Thesis (MScEng (Mechanical and Mechatronic Engineering))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: This project investigates the use of Rapid Prototyping (RP), with specific focus
on Three Dimensional Printing (3DP), in the manufacture of complex shaped advanced
composite parts, using variants of the Resin Transfer Moulding (RTM)
method of composite manufacture. This study developed design guidelines, cost
models and a process chain by studying data obtained by making example parts,
from literature and consultation with industry. Advanced composite materials offer
some of the best low weight and high specific strength properties for the solution
of design problems. A major disadvantage of these processes, however, is the
low production rates possible and the need of costly moulds. The 3DP technologies
combined with the RTM composite process was found to enable a lowering
of costs and increase in productivity if smaller batch sizes are considered. The
most meaningful area of application for RP techniques seems to be for smaller
and more complex components. The geometrical freedom allowed by RP technologies
allowed the manufacture of parts which are challenging to manufacture
by conventional technology such as CNC machining. Example part case studies
were completed for a simple part utilising the one sided mould Resin Infusion
RTM variant as well as for a complex part utilising the closed mould Vacuum Assisted
Resin Transfer Moulding (VARTM) process variant. During these two case
studies it was clear that proper part infusion with resin is critical for the manufacture
of good quality composite parts free of voids and dry spots. It is possible to
improve the resin infusion by correct placement of resin inlet and outlet ports as
well as resin channels incorporated in the mould. Correct placement of these features
for the case studies was obtained through simulations done with RTM-Worx
software. Results also indicated that another useful application of RP technology
to RTM is the manufacture of disposable cores for parts with thick cross sections.
Resin channels were included on the surface of these cores to improve the mould
filling with resin and consequently part quality. An early cost estimation model,
based on the work of Veldsman (1995), was developed for the combined RP and
RTM manufacturing process. This model may help designers to eliminate expensive
design features and enables a quick cost comparison with competing processes.
Drawbacks of applying RP techniques to RTM include the limited lifetime
of moulds produced with 3DP and the size and accuracy limitations of the RP
t echnology.<br>AFRIKAANSE OPSOMMING: Hierdie projek handel oor die toepassing van die drie-dimensionele druk metode
van Snel-Prototipering (Rapid Prototyping) op die vervaardiging van komplekse
gevorderde saamgestelde materiaal komponente met die Hars-Inspuit Giet
(Resin Transfer Moulding) metode. Die projek behels die opstel van ontwerpsriglyne,
koste-modelle en ’n proses-ketting deur data te bestudeer wat bekom
is deur middel van die vervaardiging van eksperimentele parte, literatuurstudie
asook raadpleging met individue in die industrie. Gevorderde
saamgestelde materiale verskaf van die beste sterk, dog ligte oplossings vir sekere
ontwerpsprobleme. ’n Ernstige nadeel van hierdie materiale is egter die stadige
produksietempo moontlik en die vereiste van duur gietstukke. Die Snel-
Prototipering metodes, gekombineerd met ’n saamgestelde materiaal vervaardigingsproses,
maak laer kostes met beter produktiwiteit moontlik indien ontwerpers
die part grootte- en akkuraatheidsbeperkings in ag neem. Die mees betekenisvolle
area van toepassing blyk kleiner en meer komplekse komponente te
wees. Die vryheid in geometrie wat moontlik gemaak word deur die Snel-
Prototipering tegnologie laat die vervaardiging toe van parte wat uitdagend is om
te vervaardig met konvensionele tegnologie soos CNC masjinering. ’n Gevallestudie
is voltooi vir ’n eenvoudige part vervaardig met die enkelkant gietstuk
vakuum-infusie weergawe van die Hars-Inspuit Giet metode asook vir ’n komplekse
part wat vervaardig is met die geslote gietstuk Vakuum Hars-Inspuit Giet
weergawe van die basiese metode. Dit het tydens die twee gevallestudies duidelik
geword dat deeglike hars infusie van kritieke belang is vir die vervaardiging van
goeie kwaliteit parte sonder enige droë kolle of lugruimtes. Dit is moontlik om die
hars infusie te verbeter deur hars inlate en uitlate asook hars kanale in die korrekte
posisies te plaas. Die korrekte posisies vir hierdie komponente is verkry deur
middel van ’n reeks simulasies met die RTM-Worx sagteware. Resultate dui ook
daarop dat Snel-Prototipering tegnologie handig te pas kom by die vervaardiging
van verbruikbare kerne vir saamgestelde materiaal parte met groter diktes. Hars
kanale kan maklik op die kerne se oppervlak geskep word om die hars verspreiding
en gevolglik part kwaliteit te verbeter. ’n Vroeë kostevoorspellings model,
gebaseer op werk voltooi deur Veldsman (1995), is saamgestel vir die gekombineerde
Snel-Prototipering en Hars-Inspuit Giet proses. Hierdie model kan gebruik
word om duur ontwerpsbesonderhede op parte te elimineer en om ’n vinnige
koste vergelyking met ander vervaardigingsprosesse te toon. Nadele van die toepassing
van Snel-Prototipering tegnieke op Hars-Inspuit Giet sluit die beperkte
gietstuk-leeftyd en beperkte akkuraatheid in.

In conjunction with the Leaders for Global Operations Program at MIT.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 102-106).<br>Carbon Fiber Reinforced Polymer (CFRP) composite manufacturing requires the CFRP part on the associated tool to be heated, cured, and cooled via a prescribed thermal profile. Current methods use large fixed structures such as ovens and autoclaves to perform this process step; however heating these large structures takes significant amounts of energy and time. Further, these methods cannot control for different thermal requirements across a more complex or integrated composite structure. This project focused on the below objectives and approaches: - Gather baseline energy and performance data on ovens and autoclaves to compare with estimations of new technologies; - Determine feasibility, applicability, and preliminary thermal performance of proposed heated tooling technologies on certain part families via heat transfer analyses. The project yielded the below results and conclusions: - Proved the capability of the modeling software to mimic an oven cure with less than 3% error in maximum exothermic temperature prediction; - Provided guidelines on when to use 1D, 2D, and 3D heat transfer analyses based on part thickness; - Concluded which size/shape of parts would work best for the single sided integral heating technologies; - Calculated energy intensity of incumbent technologies for comparison of future experiments on integrally heated tooling. Overall, this project helped steer the team into the next phase of their research of the technology and its applications. It provided recommendations on what type of parts the technology can be used as well as quantified the energy intensity of incumbents for comparison.<br>by Harrison Scott Bromley.<br>S.M.<br>M.B.A.

Whatcott, Tyler Blaine. "Effects of Conformal Cooling Channels on Additively Manufactured Injection Molding Tooling." BYU ScholarsArchive, 2020. https://scholarsarchive.byu.edu/etd/8727.
Full textAbstract:
This study focuses on the cycle-averaged mold temperature of additively manufactured injection molding tooling and how it is affected by conformal cooling channels. This was done by producing a benchmark mold out of Digital ABS produced by Stratasys, an acrylic based photopolymer, which was then used to produce injection molded parts until tool failure. Another, more cost-effective material, High Temp Resin produced by Formlabs, another acrylic based photopolymer, was also tested but yielded very little success. Then the mold design was altered by adding conformal cooling channels and again tested by producing injection molded parts while tracking the mold temperature. This experimentation was then compared to an injection molding cooling channel model in order to validate the model for use with additively manufactured tooling with conformal cooling channels for use in injection molding. The benchmark Digital ABS mold was able to produce 66 shots in the injection molding machine before complete mold failure. The Digital ABS mold had a cycle-averaged mold temperature of about 155°F. The High Temp Resin mold was able to produce 3 shots before complete mold failure. The High Temp Resin material is much more brittle, and the mold design did not take into account how brittle the material was. The Digital ABS mold with conformal cooling channels had a cycle-averaged mold temperature of 111°F. This is significantly lower than without cooling channels and has a high potential for improving tooling life. The cooling channel model predicted the cycle-averaged mold temperature to be 116°F. This proved to be a very good model and can be used as a design tool when choosing cooling channel geometry and position in additively manufactured tooling. This research shows the potential that conformal cooling channels have to help improve additively manufactured tooling life for injection molding. As shown in other research done, the ability to maintain the mold below 120°F significantly improves the life of additively manufactured tooling. The results of this study demonstrate the effectiveness of conformal cooling channels in controlling mold temperature. It should be researched further, but the use of conformal cooling channels has the potential to produce more production or prototype parts with additively manufactured tooling for injection molding.

Full textAbstract:
3D printing technologies have been gaining a lot of popularity in the last fifteen years, technologies like Fused Deposition Modeling (FDM) 3D printing have never been as accessible as they are today, and with the introduction of the desktop 3D printer, the technology is becoming a mainstream tool for developing prototypes and direct part production from a Computer-Aided Design (CAD) file. In an industrial context, the technology is utilized for different purposes, among which is the development and production of customized and task-specific tools. The proposed work in this thesis is an approach to simplify and streamline the development process of customized production tooling and workstation. The approach was used to identify problems and improvement opportunities at a production facility that delivered IT products. Furthermore, the Technical framework included in the proposed approach provided a guiding path to follow for the prototype development of tools to address identified problems. Developed tools and proposed solutions positively affected the production line work procedure and were accepted and adopted. While other solutions required further exploration and iterative cycles as some reluctance was experienced hence it implied changes in the workflow and daily routines.

Full textAbstract:
Användningen och intresset för additiv tillverkning (AM) har ökat markant de senaste åren och det finns en teori kring att tillverkningsmetoden kan vara det nästa steget i den industriella revolutionen. Eftersom AM fortfarande befinner sig i utvecklingsstatidet går det att anta att tekniken ännu inte uppnått sin fulla potential och att det kan komma att finnas möjligheter att implementera tekniken i fler branscher och företag. Detta skulle innebära en bredare marknad för AM. Syftet med examensarbetet var att undersöka vilka möjligheter och hinder som finns för ökad användning av AM i Sverige. Studien genomfördes genom kvalitativa intervjuer med åtta olika verksamheter tillhörande den svenska industrin och en litteraturgenomgång för att presentera nuläget för AM i svensk industriell marknad. Resultatet av datainsamlingen analyserades med modellerna PEST, 4P och slutligen SWOT. De fördelar som har setts med användningen av AM har varit minskade ledtider, minskade kostnader för tillverkning av produkter och verktyg, minskat materialspill och en optimal designprocess med ökad kreativitet. De begränsningar som finns i tekniken i dagsläget är att priset för material och maskiner är dyrt. Vidare anses även kvalitet på slutdetalj, begränsad byggvolym och opålitliga processer vara problematiska. De möjligheter som finns beror huvudsakligen på den forskning som görs. Förutsättningarna för AM i svensk industri kommer att bero på hur tekniken kommer att utvecklas. De hinder som finns är kopplat till kompetensbrist och att det inte finns befintliga standarder för material eller process inom AM.<br>Within the industrial sector, an increased interest and usage of Additive Manufacturing (AM) throughout the decade has been formed. The layer-upon-layer building technology has been seen and recognized as one of the next industrial revolutionizing methods of production. As the technology is still in the trending and uprising phase it should be considered that its full potential has not yet been achieved, as large opportunities for implementation of AM exist and that new companies and markets have a growing interest in this technology. Through this study a market research was conducted to identify and present what opportunities and obstacles there are for an increased usage of AM in Sweden. A literature study on the Swedish market has been made to present the market as of today. Eight qualitative interviews have also been conducted with companies within the industrial sector to identify the areas of use within AM for production. The concepts and models used to analyze these questions was PEST, Marketing Mix and SWOT. The concluded results for advantages in using AM are shortened lead times, reduced costs of production of components and tools, reduced material waste and optimization of design processes with increased creativity. The concluded challenges are expensive materials and machine, the quality of finished components, limited printing volume due to the 3D-printers and reliability of printing processes. The finalized opportunities that are presented in this work are that AM is dependent on how much research on the subject and factors around it is done. How AM will be applied in the coming future revolves around the advancement in the technology. The obstacles that are found in this study are lack of competence and lack of standard for materials and processes within AM.

Thesis (MScEng (Industrial Engineering))--University of Stellenbosch, 2010<br>ENGLISH ABSTRACT: Additive Manufacturing (AM) refers to the technologies that use Computer Aided Design
(CAD) data to produce plastic, metal, ceramic, paper, wax or composite materials parts.
Their ability to join thin layers of liquid, powder or sheet materials together permits the
production of parts, which are difficult or even impossible to produce, using any other
manufacturing method. Even though these technologies are still developing, they are
considered a major breakthrough in industry.
One of the main problems that is facing the improvement and the spread of AM
technologies, and its benefits worldwide, is the lack of knowledge about them. Still a lot of
countries, educational and industrial organizations do not even know about AM
technologies. This lack of knowledge of such technologies is keeping their cost artificially
high, which is limiting the access to more AM advanced technologies and materials. It also
makes it difficult to market the technologies and those who do not use AM technologies yet
become unable to compete against those who do.
The numbers of AM systems are continually growing, their capabilities and applications are
improving and their cost is decreasing. Today there are more than 40 companies that
produce over 100 different systems in Canada, China, France, Germany, Israel, Italy,
Japan, South Korea, Sweden and the United States. These systems vary in their strengths,
defects, applications, functions and limitations. This growth has led to an increase in current
and potential users of AM from both the manufacturing and educational sectors. These
users are however facing increasing complex problems when it comes to selecting the most
appropriate commercial system(s) to suit their needs.
The aim of this study is to develop an AM system selection program. The program will
serve both as an educational tool and a decision making support tool to assist any potential
purchasers in both the educational and industrial sectors. The AM system selection
program is divided into two sections: the learning section and the selecting section. The
learning section introduces the AM technologies by imparting knowledge to the new users;
moreover, it inspires them to start using these technologies to get their benefits. Having a
background in AM technologies enables the new users to make educated decisions and to
discuss technical issues about the systems with the providers. The selecting section offers a decision making support tool to help the users to decide which system best suits their
needs. This study can contribute to the promotion of AM technologies and their benefits
worldwide, especially for the countries and organizations that have not yet used such
technologies.<br>AFRIKAANSE OPSOMMING: Toevoegende vervaardiging verwys na al die tegnologie wat rekenaargesteunde ontwerp
data gebruik om plastiek, metaal, keramiek, papier, saamgestelde materiale en waks parte
te vervaardig. Die vermoë van die tegnologie om dun lae vloeistof, poeier of plaatmateriaal
op mekaar te verbind laat die vervaardiging van parte wat moeilik of selfs onmoontlik is,
deur die gebruik van ander vervaardigingsmetodes. Alhoewel hierdie tegnologieë nog in ‘n
ontwikkelingsfase is, word dit as ‘n reuse deurbraak vir die bedryf beskou.
Die verbetering, verspreiding en voordele van die tegnologie word hoofsaaklik belemmer
deur ‘n tekort aan inligting daaroor. Baie lande, akademiese en industrieële organisasies is
nog nie eens bewus dat sulke tegnologieë bestaan nie. Die tekort aan inligting veroorsaak
dat kostes hoog bly en verhoed die vinnige uitbreiding van nog meer gevorderde
tegnologieë en materiale. Verder bemoeilik dit ook die bemarking van die tegnologieë.
Die aantal toevoegende vervaardigingsmasjiene groei jaarliks met beter vermoëns, laer
kostes en ‘n groter verskeidenheid van toepassings. Tans is daar meer as 40 vervaardigers
wat meer as 100 verskillende masjiene vervaardig in Kanada, China, Frankryk, Duitsland,
Israel, Italië, Japan, Suid-Korea, Swede en Amerika. Al die masjiene verskil ten opsigte van
hul funksies, beperkings en ook ten opsigte van sterkte, materiale en toepassings van
parte. Die groei het gelei tot ‘n toename in gebruik van die tegnologie deur huidige en
potensiële nuwe gebruikers van beide die vervaardigings en akademiese sektore. Die
keuse van ‘n geskikte sisteem wat aan al ‘n gebruiker se vereistes voldoen, raak elke dag
meer kompleks.
Die doel van hierdie studie is die ontwikkeling van ‘n seleksie program vir toevoegende
vervaardigingmasjiene. Die program sal dien as ‘n opleidingshulpmiddel en as ‘n basis vir
masjienseleksie deur potensiële kopers. Die program bestaan uit twee dele: die
opleidingsgedeelte en die selekteringsgedeelte. Die opleidingsgedeelte beskryf die
verskeie toevoegende prosesse en motiveer gebruikers om die tegnologie aan te skaf
weens die voordele. ‘n Agtergrond oor die verskeie tegnologieë stel die gebruiker in staat
om ingeligte besluite te neem en tegniese vrae te kan stel aan verskaffers. Die
selekteringsdeel het ‘n besluitnemingstruktuur wat help om die regte masjien te kies ten
opsigte van verlangde vereistes.
Hierdie studie kan help met die bevordering van toevoegende tegnologieë en hul voordele,
veral vir lande en organisasies wat nog nooit voorheen sulke tegnologieë gebruik het nie.

Syngas fermentation via gasification is a two-stage process, which contains gasification of feedstock into syngas and syngas bio-methanation by anaerobic microorganisms. This project is a study on syngas fermentation. The gasification feedstock can be difficult-to-degrade solid waste so; waste volumes are reduced while green energy is produced. The main target of this thesis was to study novel configurations of reverse membrane bioreactor (RMB) in order to retain microbial cells inside the digester and thereafter increase methane production. In the first experiment, microbial cells encased in PVDF sachets were proved to perform efficiently in batch mode in comparison to free cells at optimum temperature, 55 oC. Moreover, encased cells in co-digestion of syngas and organic waste exhibited higher methane amounts compared to pure syngas treatment. Encased cells were then tested in thermophilic semi-continuous process and showed better performance compared to the free cell reactor. The RMB containing encased cells retained successfully the cells during the 154 days of the experiment, while free cells were washed-out. The highest amounts of methane from RMB and the free cell reactor were produced during the 126th - 130th day (6 and 1.5 mmol/day, respectively). In the last experiment, a RMB containing 13 membrane layers of enclosed cells was studied and compared to a conventional reactor of free cells. The RMB performed successfully in syngas bio-methanation under semi-continuous conditions during 49 days. The highest methane amount produced was 10 mmol/day in both RMB and free cell reactor.<br>Program: Industriell bioteknik

Full textAbstract:
Thesis (PhD (Industrial Engineering))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: Information on the milling of Ti6Al4V is limited; with most studies concluding that it is not possible to obtain a significant increase in the material removal rate (Qw). Tool wear maps can be a diagnostic instrument for failure analysis. Cutting speed (vc), maximum un-deformed chip thickness (heMax) and the radial immersion percentage (ae/Ø %) are the key variables in understanding the milling of titanium alloys. The objective of this research study was to construct tool wear maps for the milling of Ti6Al4V. This will form the foundation of understanding the cutting demands on the tool, in order to analyse the main wear mechanisms. Remedial actions, which are developed by tool suppliers, can be considered and integrated via this understanding of the failure modes and related mechanisms.
Firstly, experimental data from background studies, literature and industry on wear rates and wear mechanisms pertaining to the milling conditions was gathered to construct the tool wear map. Mathematical models describing the wear behaviour for these conditions were also investigated. Secondly, work piece failure maps have been superimposed onto the tool wear maps constructed to understand the global failure boundaries. Experimentation was carried out to validate the constructed maps. The tool wear map could then be used to discuss the observed effects and consider remedial actions.
Cutting speed corresponds to the magnitude of the thermal load and heMax represents the mechanical load. The ae/Ø % defines the duration of the exposure to the thermal load at the edge of the cutting tool. This investigation has shown the following issues to be of importance when considering tool performance via the tool wear map approach:
1. The key to designing tool wear maps is to identify the most economic Scheduled Replacement Time (SRT) for the specific components. Knowing the correct SRT makes it possible to optimize the milling conditions so that the cutting tool wears gradually under the cutting conditions, and lasts longer than the economic SRT.
2. Increased vc will decrease tool life (TL). However, in low transverse rupture strength tools there may be a minimum vc below which mechanical overload may occur. Similarly, a local maximum TL (a sweet spot) may exist if there is a phase change in the work piece material.
3. Increased heMax will decrease TL. However, heMax must be kept below a maximum critical value to avoid mechanical overload, but above a minimum critical value to avoid work hardening.
4. Increased ae/Ø % will decrease TL. The best balance of high Qw and economic TL is found with ae/Ø between 30-40% for rough milling. In finish milling the radial cut is limited to 1 mm finishing stock of the work piece. This study revealed the following important factors when considering work piece failure in the milling of Ti6Al4V:
1. Increased vc will reduce the cutting resistance of the work piece and increase Qw. However, vc must be kept below a maximum critical value to avoid work piece material burn, but above a minimum critical value to avoid burring and poor surface finish, due to tool build-up and chip jamming.
2. Increased heMax will increase the cutting resistance of the work piece and increase Qw. The heMax must be kept below a maximum critical value to avoid poor surface finish, poor flatness and parallelism (due to work piece bending). Likewise, heMax must be kept above a minimum critical value to avoid work hardening and burring.
The constructed tool wear maps are validated with experimental work. This research work identified safe zones to productively mill Ti6Al4V, while producing components with a sufficient surface integrity.<br>AFRIKAANSE OPSOMMING: Inligting rondom freeswerk van Ti6Al4V is beperk en volgens meeste studies is dit nie moontlik om ‗n wesenlike toename in die materiaal verwyderingstempo (Qw) te behaal nie. Snybeitel verwerings kaarte kan ‗n diagnostiese hulpmiddel wees tydens analisering van snybeitels. Snyspoed (vc), maksimum onvervormende spaanderdikte (heMax) en radiale snitdiepte persentasie (ae/Ø %) is die sleutel veranderlikes om die freeswerk van Ti6Al4V beter te kan verstaan. Die doel van die navorsingstudie was om snybeitel verweringskaarte vir die freeswerk van Ti6Al4V te bou. Die werk vorm ‗n fondasie om die eise van freeswerk op die snybeitel beter te verstaan. Sodoende kan die hoof verweringsmeganismes analiseer word. Regstellende aksies wat deur snybeitel vervaardigers ontwikkel is, was ondersoek en integreer met die huidige kennis rondom die falingstipe en verwerings meganismes.
Aanvanklik was eksperimentele data van agtergrond studies, literatuur en industrie oor die verweringstempos en -meganismes rondom die freeswerk van Ti6Al4V versamel. Hiermee is verweringskaarte gebou. Wiskundige modelle wat die verwering kan beskryf was ook ondersoek. Daarna was werkstuk falingskaarte integreer met die ontwikkeling van die snybeitel verweringskaarte om sodoende die grense in geheel te verstaan. Eksperimentele werk was gedoen om die snybeitel verweringskaarte se uitleg te toets. Sodoende kon die snybeitel verweringskaarte gebruik word om die gedrag van die snybeitel te bespreek en regstellende aksies te ondersoek.
Snyspoed (vc) stem ooreen met die grootte van die termiese lading en heMax verteenwoordig die grootte meganiese lading. Die ae/Ø % omskryf die tydperk van blootstelling aan die termiese lading op die snyrand. Die ondersoek het bewys dat die volgende faktore belangrik is wanneer snybeitel prestasie met die snybeitel verweringskaart evalueer word:
1. Die sleutel tot die ontwerp van snybeitel verweringskaarte is om die mees ekonomies beplande vervangingstyd (SRT) vir spesifieke komponente te identifiseer. Sodoende is dit moontlik om die frees toestande te optimaliseer, waaronder die snybeitels geleidelik sal verweer onder die eise en vir ‗n langer tydperk as die ekonomiese SRT sal kan sny.
2. Toename in vc sal snybeitelleeftyd (TL) laat afneem. Snybeitels met ‗n lae dwarsbreuksterkte, kan ‗n minimum vc hê waaronder meganiese oorlading plaasvind. Terselfdertyd, kan ‗n maksimum TL (‗n ―sweet spot‖) bestaan as daar ‗n fase verandering in die werkstuk materiaal plaasvind.
3. Toename in heMax sal TL laat afneem, maar moet laer as ‗n maksimum- en hoer as ‗n minimum kritiese waarde wees, om sodoende meganiese oorlading en werksverharding onderskeidelik te vermy. 4. Toename in ae/Ø % sal TL laat afneem. Die beste balans tussen TL en ae/Ø % is gevind met ae/Ø % tussen 30-40% vir growwe freeswerk. In afrondingsfreeswerk is die radiale snit beperk tot 1 mm van die oorblywende werkstuk.
Die ondersoek het bewys dat die volgende faktore belangrik is wanneer werkstukfaling in ag geneem word met snybeitel verweringskaarte:
1. Toename in vc sal die werkstukweerstand geleidelik verminder en Qw laat toeneem. Ongelukkig is vc beperk tot ‗n maksimum kritiese waarde om werkstukfaling te voorkom weens ‗material burn‘. Die snyspoed moet ook hoër as ‗n kritiese waarde wees om werkstukklitsing en swak afronding weens spaander probleme te vermy.
2. Toename in heMax sal die werkstuk weerstand geleidelik vermeerder en Qw laat toeneem. Die heMax is beperk tot ‗n maksimum kritiese waarde om swak werkstuk afronding, weens die buiging van die werkstuk, te vermy. Terselfdertyd moet heMax hoër as ‗n kritiese waarde wees om werkstukverharding en -klitsing te voorkom.
Die saamgestelde snybeitel verweringskaarte was bekragtig met eksperimentele werk. Die navorsingswerk het veiligheidsareas identifiseer om Ti6Al4V produktief te frees, sonder om die werkstukoppervlak krities te beïnvloed.

Published Article<br>The design, manufacture and use of diaphragm valves in the minerals industry is becoming increasingly important since this sector is restricted from using excessive amounts of water for their operations. This forces a change in the flow properties of these devices from turbulent to laminar in nature and thus necessitates the characterization of these flows for future designs. Furthermore, diaphragm valves have a short service life due to a variety of reasons that includes the abrasive nature of the flow environment.
This paper describes the activities of the Adaptronics Advanced Manufacturing Technology Laboratory (AMTL) at the Cape Peninsula University of Technology in the research and development of diaphragm valves using rapid prototyping technologies. As a first step, an experimental diaphragm valve was reverse engineered and retrofitted with ultrasonic transducers used in Ultrasonic Velocity Profiling (UVP) measurements. The use of this device enables measurements of velocity profiles to gain insight into the flow structure within the valve and the increased pressure losses generated within the valve. It also showed that components fabricated using the Z-Corporation machine could withstand the working environment of diaphragm valves. Research is now conducted on ultrasonic transducer placement in the device to further enhance the velocity profiling through the device.
As a second step we produced a thin-walled stainless steel diaphragm valve using rapid prototyping technology and investment casting processes. A study of the durability of this device will be conducted and certain geometric and manufacturing aspects of this valve will be discussed.

material, measures etc. Nowadays, that work is covered by the Brazilian Nationa Health Service (SUS) and is accomplished in a manual way being used commo measuring tapes characterizing a quite rudimentary, handmade work and without an accuracy.In this dissertation it is presented the development of a computer integrate tool that it include CAD theory, for visualization of both above and below-knee prosthesis in 3D (i.e. OrtoCAD), as well as, the design and the construction a low cos electro-mechanic 3D scanner (EMS). This apparatus is capable to automatically obtain geometric information of the stump or of the healthy leg while ensuring smalle uncertainty degree for all measurements. The methodology is based on reverse engineering concepts so that the EMS output is fed into the above mentioned academi CAD software in charge of the 3D computer graphics reconstruction of the residualimb s negative plaster cast or even the healthy leg s mirror image. The obtained results demonstrate that the proposed model is valid, because it allows the structura analysis to be performed based on the requested loads, boundary conditions, material chosen and wall thickness. Furthermore it allows the manufacturing of a prosthesis cartridge meeting high accuracy engineering patterns with consequent improvement in the quality of the overall production process<br>A fabrica??o de pr?teses para amputados de membros inferiores (transfemural e transtibial) exige a confec??o de um cartucho com encaixe adequado e personalizado ao perfil de cada paciente.

Il potenziale delle nuove tecnologie digitali applicate al settore industriale ha consentito di ridurre enormemente la durata dei cicli produttivi grazie alla rapida gestione di quantità di dati sempre più considerevoli attraverso l’introduzione delle Macchine a Controllo Numerico (Computer Numerical Control – CNC).
Nel corso delle ultime tre decadi, l’industria manifatturiera ha subito notevoli e sostanziali cambiamenti grazie ad una sempre più forte connessione con il mondo dell’informatica.
La più grande rivoluzione in tale ambito è stata segnata dall’avvento della Manifattura Additiva (Additive Manufacturing - AM), conosciuta sotto diversi nomi, tra i quali Prototipazione Rapida (Rapid Prototyping), Manifattura Rapida (Rapid Manufacturing) o Libera Fabbricazione di Forme (Free Form Fabrication).
Materia di ricerca e sviluppo sin dalla fine degli anni ’80, la Manifattura Additiva consente la creazione di elementi fisici tridimensionali partendo da modelli CAD attraverso la sovrapposizione successiva di materiale strato per strato (layer by layer), offrendo i benefici di una elevata flessibilità geometrica degli elaborati, altrimenti irraggiungibile attraverso le tradizionali tecniche di Manifattura Sottrattiva operanti per asportazione di materiale. In seguito ad intensive ricerche, progressi significativi sono stati fatti nello sviluppo e nella commercializzazione di nuovi ed innovativi processi AM.

碩士<br>國立臺灣科技大學<br>機械工程系<br>88<br>The purpose of this research is to increase performance of rapid tooling by developing a new powder-epoxy material and by introducing metal powder metallurgy techniques to molding industry. The study involves the application of the injection molding, new material for temporary mold, as well as the process development of rapid tooling for permanent mold using cold-isostatic pressing (CIP) technology.
The injection molding of driving mirror has been completed by using aluminum-epoxy compound mold. In general, the prototyping of the driving mirror is handwork or built by a rapid prototyping system and the cast-molding technology directly generates the mold. This study is to apply FRP(fiber reinforce plastic) to build the prototype mirror along with a casting process to generate the aluminum-epoxy compound mold.
Because the expensive of the aluminum-epoxy compound used in current temporally mold, which draw back the interesting of mold makers. New material has been developed in this research and intends to reduce the cost of the compound. As the result, the formula of experience for the mix ratio of aluminum powder and epoxy has been suggested.
In order to increase the strength of the aluminum-epoxy compound mold to compete the conventional steel mold, the CIP process as one of the typical powder metallurgy technology has been introduced. The study is to focus on pressing tooling using the previous developed ceramic-epoxy compound and followed by the process study of injection molding using CIP technology. The result shows that the final aluminum mold after pressing and sintering steps reveals a very good accuracy (0.05mm) and gains a great enhancement compared to current aluminum-epoxy compound mold.

Full textAbstract:
碩士<br>國立臺灣大學<br>工業工程研究所<br>84<br>Rapid prototyping (RP) is a new technology which builds
physical prototypes by combining layered raw material into
desired shape. Reverse engineering (RE) refers to the working
process which builds CAD models or physical prototypes by
consolidating measured data from a physical object. Both
technologies contribute a great deal in facilitating computer
aided design and manufacturing for product development. While
it is seldom concerned that the two technologies should be
integrated in order to gain better benefit. In this study, a PC-
based integrating system entitled RP_RE INTEGRATION is proposed
and implemented which entails three tasks: (1) Interface
CAD_RP, (2) Interface RP_NC, and (3) Interface RE_CAD. The
CAD_RP interface translates geometric models into triangulated
stereo lithography (STL) files which drives the RP machines in
order to integrate RP and CAD systems. The RP_NC interface
translates STL files into NC tool path to integrate RP and NC
systems. The RE_CAD interface re-builds geometric models from
measured data to integrate RE systems with RP, CAD, and NC
systems. The thesis is constructed on Pentium 90 and Windows 95
with Visual C++ v2.0 and verified by Helisys/Lom (RP), and
Micromil/Denford (NC). The integrated RP and RE system can be
structured when all proposed interfaces are completed.

Full textAbstract:
碩士<br>國立臺灣大學<br>機械工程學研究所<br>88<br>Rapid Prototyping and Reverse Engineering are becoming more and more popularly in the industry because of Rapid Prototyping can reduce design time and cost of product and Reverse Engineering offers a new way of product design. The integration of both technologies currently use CAD system to rebuild surface model or solid model from scan points, then translate to STL format for rapid prototyping system. Disadvantages of the method are spending long time on rebuild model and STL format having redundancy and accuracy problems.
This thesis propose a integrated method which bases on the theory of NURBS curve, direct slicing and adaptive slicing. The objectives are improving the disadvantages of currently method and constructing an integrated system by Visual C++ language, the main function of this system is to generate HPGL file directly from scan points. By comparing file size of STL file and HPGL file reveals that system has advantages of direct slicing and adaptive slicing. The HPGL file, which output from system, can be accepted by rapid prototyping machine. These results show the feasibility of integrated method.

Full textAbstract:
Intervertebral disc (IVD) degeneration disease (IDD) is considered the main cause for low back pain (LBP), which has a world socioeconomic burden of 70 billion euros a year. Tissue Engineering (TE) is an exponentially growing area due to its potential of finding patient-specific treatments in terms of immunological compatibility by using the patient’s own cells. Though, it is possible to increase TE patient-specificity by combining other technologies such as Reverse Engineering (RE) and Rapid Prototyping (RP). In this sense, it is possible to prepare a biodegradable scaffold that is both immunological and structurally compatible. This strategy has the potential to significantly increase implant integration and decrease immunological rejection, allowing the scaffold to be progressively replaced with newly synthesised tissue to ultimately regenerate the IVD into a fully functional anatomical motion segment.
Herein is reported a preliminary proof-of-concept for that strategy using rabbit IVD’s cells as well as morphology and structure. In this sense, the annulus fibrosus (AF) structure was replicated by RE and RP into a polycaprolactone scaffold, and the cells were encapsulated in methacrylated gellan gum (GG-MA) hydrogel as a nucleus pulposus (NP) substitute. The AF scaffold’s cytotoxicity, mechanical behaviour, porosity and superficial morphology were also analysed. It was observed a significant level of biocompatibility from the AF replica and a similar porosity in relation with the native IVD. Cell adhesion, proliferation and viability were assessed until 21 days of culture in GG-MA. The metabolic activity was higher in the NP cells than in the fibroblast cell line, both cultured in GG-MA. In the future, this novel strategy is envisaged to treat IDD, and remove LBP, by fully regenerating the intervertebral disc.<br>A degeneração do disco intervertebral é considerada a maior causa de dor lombar, que por sua vez tem um impacto socioeconómico mundial na ordem dos 70 mil milhões de euros por ano. A Engenharia de Tecidos é uma área de investigação que está a crescer exponencialmente e que tem o potencial de desenvolver novos tratamentos, livres de rejeição imunológica, uma vez que são utilizadas células do próprio paciente. No entanto, é possível aumentar esse potencial de compatibilidade com o paciente combinando Engenharia Reversa com Prototipagem Rápida. Com isto visa-se o desenvolvimento de uma estrutura biodegradável e compatível tanto imunologicamente com estruturalmente, que vai sendo progressivamente substituída por novo tecido até se alcançar uma regeneração definitiva do disco intervertebral.
A prova-de-conceito preliminar desta estratégia terapêutica é reportada neste estudo através da utilização tanto de células, como a própria estrutura e morfologia, do disco intervertebral de coelho. A estrutura do anel fibroso foi replicada por Engenharia Reversa e Prototipagem Rápida em policaprolactona, enquanto que para servir como substituto do núcleo pulposo foram encapsuladas células num hidrogel de goma gelana metacrilada. A citotoxicidade, comportamento mecânico, morfologia superficial e porosidade da réplica do anel fibroso foram analisadas. Verificou-se que a porosidade é similar ao disco nativo e que o nível de biocompatibilidade está acima de 80%. As imagens de miscroscopia mostraram que as várias camadas da estrutura apresentam uma boa ligação após a solidificação do polímero. A adesão, proliferação e viabilidade celular na goma gelana metacrilada foram analisadas até 21 dias de cultura. Observou-se uma maior actividade metabólica nas células do núcleo pulposo do que na linha celular de fibroblastos, ambas encapsuladas em goma gelana metacrilada. Como trabalho futuro, pretende-se utilizar esta estratégia para tratar casos de degeneração do disco de uma forma efetiva em que o resultado final, após absorção da estrutura, é um disco intervertebral nativo biomecanicamente funcional.

碩士<br>長庚大學<br>機械工程研究所<br>89<br>Abstract
Clinical surgeons have always needed to perform anaplasties for patients, due to inborn or acquired factors, who are injured in the skull, face or limbs. At present, anaplasties are invariably executed solely based on the surgeon''s experiences - planning the steps of the surgery and designing the shape of the implant all on an x-ray film. The entire process not only consumes time but also affects the quality of the implant. In modern times, the technology of "Reverse Engineering" has been broadly applied to industries of moulds, aerospace and automobiles but still not so much in the medical field. The purpose of our research, is to develop RE for medical application through the aid of CAD/CAM、RP/RT and image scanning and regrouping technologies. As a result, our findings will help doctors perform skull and facial implantations、darns for artificial ears、designing and making the template for orientation of the lower jaw and pre-surgery-route-plannings and simulations. In addition, our study will also employ medical RE and RP/RT technologies in designing and manufacturing even-pressured shoe insoles for rehabilitation of diabetics.
The content of our thesis includes 4 sub-topics: making and development of the flow path of medical RE、making and development of the application of implantation for skull and facial surgeries、3D images and physical models for the application of surgical simulations and finally, designing and manufacturing even-pressured shoe insoles for rehabilitation of diabetics. The first section of the thesis defines the distinguishing characteristics for the technology of medical RE/RP and sets forth the actual-clinical application and verification of CT、Thresholding、Stack Region Growing、Image Segmentation and Surface Separation. The second section of the thesis deals with the manufacture and application techniques of implants for skull and facial surgeries which includes repairment implantation、darns for artificial ears、designing and making of the template for orientation of the lower jaw. Moreover, actual-clinical cases will be presented to prove the practicability of our newly developed techniques. The third section of the thesis adopts methods of "Digital Imaging" and "Physical Modeling" in pre-surgery-route-plannings and simulations for skull and facial surgeries. Besides comparing and contrasting the two methods mentioned above, we will also verify the feasibility of the surgical procedures through a light-hardening-resin model for surgical simulation. The final section of the thesis, assisted with the foot-pressure measuring system developed by my instructor and integrated with the image collecting system, we have developed a "Simultaneous Foot Profile and Pressure Distribution Measuring System". In addition, we have also developed the CAD techniques for designing even-pressured shoe insoles for rehabilitation of diabetics.
In completion of our research, our developed medical RE manufacturing flow path and the application techniques of implantation will be used in conjunction with the clinical needs through CAD manufactured implants、artificial ears or positioning board. Besides shortening the time for performing a surgery, our methods will also improve the quality of the surgery. Furthermore, the proof of the application of "Digital Imaging" and "Physical Modeling" in surgical plannings can provide clinical surgeons pre-surgery-route-plannings and simulations. In which, DI offers repetitive-surgical simulations and PM offers the physical segmentation drills for doctors. As for the technologies of "Simultaneous Foot Profile and Pressure Distribution Measuring System" and the even-pressured shoe insoles for rehabilitation of diabetics, will effectively aid in the production of even-pressured shoe insoles for rehabilitation of diabetics with the use of RE and RP. Our method not only establishes a unique style of making the rehabilitation shoes but will also bring their healing power into full play.
