Abstract:

Computer-aided design (CAD) poses a brand new change of environmental art design from concept to skills. Nowadays, computer operation is a must for environmental art design, and no one can ignore such a powerful trend. This is transition period from traditional manual design mode to advanced computer design mode, and now we are standing on top of this new start point. CAD has fully performed its charm and become an indispensable tool in the field of the environmental creative art design. Mastering relevant software has become an essential skill for designers. However they often feel lost in current complex computer software, or even when they have conquered software technology difficulties, still trapped into a hard-pressed embarrassment to combine design with ideas. This dissertation starts from CAD definition, discusses CAD development and its own characteristics, and further on CAD applications in environment art design, main types and functions in current CAD software. The end of this article also gives an outlook on future effects and scheme a better vision for CAD in environmental design.

Abstract:

A methodology for measuring the organizational effectiveness of computer-aided design (CAD) was developed and applied. A total of 295 of the 500 most frequent users of CAD in a major aerospace company provided data for the study. User-CAD effectiveness was found to be influenced by 43 major factors and 145 specific system and organizational issues. The 43 factors were classified into the following categories: system functions, system hardware, working environment, system reliability and consistency, user access, user support and training, and system administration. Indexes of User-CAD Effectiveness (UE) and System Availability and Reliability (AR) were combined into an Index of CAD Organizational Effectiveness (OE). Through the application of these methods and indexes, CAD system and organizational deficiencies can be diagnosed, potential high-payoff improvements can be identified, and the impact of developmental efforts can be assessed.

Abstract:

In modern industrial production some of the major factors of successful development include: cost reduction of the production, im-provement of its quality, as well as help to minimise the time in market en-try. Computer-aided design and Computer-aided engineering (CAD / CAE - systems) are the most effective for implementation of these requirements. Possible use of this engineering modeling simulation in conjunction with the power and speed of high performance computing could reduce costs and time of each cycle of designing, and also significantly reduce devel-opment time. The introduction of new technologies, the use of high quality products and engagement of qualified personnel would allow businesses and organizations to get on a path of innovative development of design and production systems.

Abstract:

Perkembangan Teknologi yang semakin meningkat dan berkembang dapat memudahkan orang-orang yang kreatif dalam merancang system dan elektronik. Pada elektronik terdapat komponen yang sangat penting untuk menunjang komponen dan memberikan jalur penghubung antar komponen yaitu papan PCB. Sebelum adanya technology CAD untuk membuat PCB para pengembang technology Smart System/Internet of Things masih membuat PCB dengan cara manual namun seiring berjalannya waktu dan dengan berkembangnya teknologi sekarang membuat PCB sudah mudah dengan adanya Computer-Aided Design (CAD). Teknik awal seorang pengembang IoT/Smart System membuat PCB yaitu masih dengan cara membuat tata letak komponen dan menyesuaikan skala dengan komponennya setelah itu baru proses menggambar jalur menggunakan spidol permanen yang dibuat sedemikian rupa dengan apa yang telah digambarkan terlebih dahulu baru dilakukannya proses eatching. Setelah adanya technology CAD terdapat banyak perubahan disetiap tahap pembuatannya jadi tidak perlu menggambar tata letak komponen dan menyesuaikan sklanya dengan CAD itu semua sudah otomatis di tentukan. Pada pembuatan PCB dengan CAD bisa menampilkan bagian silk atau gambar bagian depan sehingga bagian silk tersebut bisa ditempel ke bagian atas PCB untuk memudahkan menentukan tempat komponennya. Proses pembuatannya juga lebih efisien dan lebih teratur dengan menggunakan CAD dari pada membuat secara manual sehingga dengan adanya Computer-Aided Design (CAD) sangat membantu dalam proses pembuatan desain PCB.

ABSTRACT Aim To review the adhesive bonding to different computer-aided design/computer-aided manufacturing (CAD/CAM) esthetic restorative materials. Background The use of CAD/CAM esthetic restorative materials has gained popularity in recent years. Several CAD/ CAM esthetic restorative materials are commercially available. Adhesive bonding is a major determinant of success of CAD/ CAM restorations. Review result An account of the currently available bonding strategies are discussed with their rationale in various CAD/ CAM materials. Conclusion Different surface treatment methods as well as adhesion promoters can be used to achieve reliable bonding of CAD/CAM restorative materials. Selection of bonding strategy to such material is determined based on its composition. Further evidence is required to evaluate the effect of new surface treatment methods, such as nonthermal atmospheric plasma and self-etching ceramic primer on bonding to different dental ceramics. Clinical significance An understanding of the currently available bonding strategies to CA/CAM materials can help the clinician to select the most indicated system for each category of materials.

Abstract:

ABSTRACTThe aim of this review was to investigate usage of computer-aided design/computer-aided manufacture (CAD/CAM) such as milling and rapid prototyping (RP) technologies for removable denture fabrication. An electronic search was conducted in the PubMed/MEDLINE, ScienceDirect, Google Scholar, and Web of Science databases. Databases were searched from 1987 to 2014. The search was performed using a variety of keywords including CAD/CAM, complete/partial dentures, RP, rapid manufacturing, digitally designed, milled, computerized, and machined. The identified developments (in chronological order), techniques, advantages, and disadvantages of CAD/CAM and RP for removable denture fabrication are summarized. Using a variety of keywords and aiming to find the topic, 78 publications were initially searched. For the main topic, the abstract of these 78 articles were scanned, and 52 publications were selected for reading in detail. Full-text of these articles was gained and searched in detail. Totally, 40 articles that discussed the techniques, advantages, and disadvantages of CAD/CAM and RP for removable denture fabrication and the articles were incorporated in this review. Totally, 16 of the papers summarized in the table. Following review of all relevant publications, it can be concluded that current innovations and technological developments of CAD/CAM and RP allow the digitally planning and manufacturing of removable dentures from start to finish. As a result according to the literature review CAD/CAM techniques and supportive maxillomandibular relationship transfer devices are growing fast. In the close future, fabricating removable dentures will become medical informatics instead of needing a technical staff and procedures. However the methods have several limitations for now.

Abstract:

The authors have developed a simple device for computer-aided design/computer-aided manufacturing (CAD-CAM) that uses an image-guided system to define a cutting tool path that is shared with a surgical machining system for drilling bone. Information from 2D images (obtained via CT and MRI) is transmitted to a processor that produces a 3D image. The processor generates code defining an optimized cutting tool path, which is sent to a surgical machining system that can drill the desired portion of bone. This tool has applications for bone removal in both cranial and spine neurosurgical approaches. Such applications have the potential to reduce surgical time and associated complications such as infection or blood loss. The device enables rapid removal of bone within 1 mm of vital structures. The validity of such a machining tool is exemplified in the rapid (< 3 minutes machining time) and accurate removal of bone for transtemporal (for example, translabyrinthine) approaches.

Abstract:

This study examined the relation of responses from two student groups toward computer-aided design (CAD) for apparel to their computer use, computer experience, or enrollment in an elective CAD course. In the non-CAD group of 46, computer anxiety was significantly correlated with computer use and computer experience as well as future enrollment in the CAD course. In the CAD group of 17, students in the CAD course were significantly less fearful of job elimination and more interested in technical aspects of computers at the end of the course than at the beginning. Data have been applied to the continued course development of computer-aided design especially for apparel-related academic programs. As one outcome, length of instruction has been recommended over a continuous 16-wk. period. Using specific instructional methods to reinforce components from both the affective and cognitive domains of learning has helped to sustain positive responses throughout similar subsequent offerings. Finally, preparation for employment was enhanced as a consequence of acquiring specific technological skills included in the CAD course.

We describe an Internet-based CAD tool that automatically designs gripper jaws that will rotate a given rigid convex polygonal part from a selected stable resting orientation to a desired final orientation to facilitate insertion or assembly. In this paper we describe the CAD algorithm, its Java implementation, and improvements that relax input specifications and improve computational efficiency. We illustrate with physical experiments using a machined aluminum part and the resulting gripper as designed by the CAD tool. We also consider cases where a solution may not exist and derive a class of triangular parts that cannot be rotated with the planar grippers.

Abstract:

The notion of â€œdesign thinkingâ€ can be regarded as a way of thinking that consists of both divergent and convergent phases. As a creative problem solving methodology, it first defines the problem with a human-centered perspective and then analyzes all the aspects of the problem as a part of a whole. This approach can be applied in all fields, including design education. With the emerging technology, computer-aided design tools and techniques have become an indispensable part of design professions, and therefore education. However, the way how computer-aided design tools and techniques should be integrated into current design education has not been discussed adequately. This study aims to frame the problems related to the current content, structure and timing of CAD courses. The alternative solutions regarding the integration of CAD courses to product design education will be proposed by using design thinking method.Keywords: design thinking, computer aided design (CAD), design educationÂ

Abstract:

Today, a substantial part of the dental crown production uses computer-aided design and computer-aided manufacturing (CAD/CAM) technology. A recent step in restorative dentistry is the replacement of natural tooth structure with pre-polymerized and machined resin-based methacrylic polymers. Recently, a new CAD/CAM composite was launched for the crown indication in the load-bearing area, but the clinical reality forced the manufacturer to withdraw this specific indication. In parallel, a randomized clinical trial of CAD/CAM composite crowns luted on zirconia implant abutments revealed a high incidence of failure within the first year of service. Fractured crowns of this clinical trial were retrieved and submitted to a fractographic examination. The aim of the case series presented in this article was to identify failure reasons for a new type of CAD/CAM composite crown material (Lava Ultimate; 3M Oral Care, St. Paul, Minnesota, USA) via fractographic examinations and analytical assessment of luting surfaces and water absorption behavior. As a result, the debonding of the composite crowns from the zirconia implant abutments was identified as the central reason for failure. The adhesive interface was found the weakest link. A lack of silica at the zirconia surface certainly has compromised the bonding potential of the adhesive system from the beginning. Additionally, the hydrolytic stress released from swelling of the resin-based crown (water absorption) and transfer to the luting interface further added to the interfacial stress and most probably contributed to a great extend to the debonding failure.

ABSTRACT Objective To compare treatment duration and quality between standard vs computer-aided design/computer-aided manufacturing (CAD/CAM) customized self-ligating systems using indirect bonding with both. Materials and Methods This comparative trial included 24 patients: 12 treated with a CAD/CAM custom indirect bonding self-ligating system (CAD/CAM) and 12 others treated with an indirect bonding self-ligating standard system (I-STD). For each group, overall orthodontic treatment (OT) time was calculated and included the time needed to place each arch as well as the duration of the alignment and fine-tuning phases. The quality of the final result was analyzed using the American Board of Orthodontics Cast-Radiograph Evaluation. Patient-reported outcome measures (PROMs) were also evaluated. Results Patient characteristics were similar between the 2 groups except for age, which was slightly lower in the I-SDT group. Overall OT time was increased by 26% in the I-STD group compared with the CAD/CAM group (497 ± 40 days vs 393 ± 55 days, P = 0.0002) due to a shorter fine-tuning phase in the latter group (P<0.01). No difference was found between the groups for alignment phase. Quality of the final result was similar (I-STD, 25.7 ± 6.1; CAD/CAM, 21.6 ± 6.3) among the groups. Finally, no difference was found in the PROMs variables. Conclusions Despite a 26% longer OT time when compared with the CAD/CAM customized bracket system, the indirect bonding self-ligating bracket system demonstrated the same quality of treatment. PROMs demonstrated a high level of acceptance and satisfaction for both techniques.

Abstract:

ABSTRACTThe use of bi-layered all-ceramic crowns has continuously grown since the introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia cores. Unfortunately, despite the outstanding mechanical properties of zirconia, problems related to porcelain cracking or chipping remain. One of the reasons for this is that ceramic copings are usually milled to uniform thicknesses of 0.3-0.6 mm around the whole tooth preparation. This may not provide uniform thickness or appropriate support for the veneering porcelain. To prevent these problems, the dual-scan technique demonstrates an alternative that allows the restorative team to customize zirconia CAD/CAM frameworks with adequate porcelain thickness and support in a simple manner.

Abstract:

The system of computer-aided design of industrial fishing gear (CAD-FG), developed by the small innovative enterprise Digital Technologies Laboratory LLC with the support of FASIE, is an import-substituting product for manufacturers and designers of bottom and mid-water trawls. At the present stage of trawl operation, the use of CAD-FG on fishing vessels will ensure the correct setting of the trawl system (trawl doors, hydrodynamic shield, loading chain, etc.) for efficient operation of the trawl. The CAD-FG system allows you to save drawings of trawls in electronic format, which creates a database necessary for analyzing designs and transferring drawings to the relevant departments and divisions. An integral part of the competencies of highly qualified personnel is their ability to work with the CAD-FG software, with which it is possible to develop drawings of bottom and mid-water trawls, as well as to model their operation processes in 3D.

Abstract:

In the rehabilitation engineering area, the pressure ulcer prevention is an important and healthy problem, especially for people with the spinal cord injured (SCI). This paper aim to develop a computer aided design and computer aided manufacture (CAD/CAM) method to manufacture custom cushions to prevent pressure ulcer. A patient’s buttock was digitized using 3D laser scanner, and the captured buttock data was processed in reverse engineering environment to generate the 3D surface model of the buttock. The 3D surface model of the buttock is imported into Unigraphics software to create the solid model; then, a flat rectangle that represents the cushion was generated under the buttock to create the buttock-cushion system. Based on the load-deformation relation of cushion materials acquired by the test, the depth of cut of the cushion was established and a CAD model of cushion shape was created through a Boolean subtraction. The CAD model of the contour is post-processed into code that the numerically controlled milling machine (CNC milling) can use to machine the cushion.

Abstract:

CAD/CAM technology (Computer Aided Design / Computer Aided Manufacturing) in the matter of fact helps in design and development of two-dimensional or three-dimensional models and their realization on numerical controlled machines. The key to direct or indirect CAD/CAM dental restorations is the measurement of dental preparation in the mouth or on the plaster die. The aim of this paper is to describe the possibilities and the way of function of different computer aided inspection (CAI) systems as a first part of CAD/CAM systems. Different researchers have presented several approaches of methods for three dimensional (3D) measurement. Today, for chairside dental treatment, only the optical method of measurement has lead to satisfactory results in practice. Laboratory CAD/CAM systems use mechanical and optical technologies for 3D measurement. Optical impression grows as a leader of CAI segment of almost every new CAD/CAM system. The most important properties of 3D scanners are: accuracy, volume and speed of measurement and ergonomy of instrument. .

Abstract:

This article focuses on engineering developments to integrate computer-aided engineering (CAE) and computer-aided design (CAD) capabilities in a software. CAD/CAE software suites are making their way to the forefront of current design practices, because they contain capabilities that allow designers to build an initial prototype that has already been analyzed by the CAE system for design flaws. Engineers at Cannondale have used an integrated CAD/CAE package to cut one year from the design time of their full-suspension Raven frame, which is both lightweight and stiff and has a suspension fork and a rear swing arm. The CAD software is used to design the bicycle frame while the CAE software immediately analyzes design flaws, which are then corrected, eliminating the need for continual prototyping. Companies are finding that the easy-to-learn nature of these CAD/CAE programs allows them to put analysis capability in the hands of design engineers for the first time.

Abstract:

AbstractThis paper presents a preliminary comparison between the role of computer-aided design (CAD) and sketching in engineering through a case study of a senior design project and interviews with industry and academia. The design team consisted of four senior level mechanical engineering students each with less than 1 year of professional experience are observed while completing an industry sponsored mechanical engineering capstone design project across a 17 week semester. Factors investigated include what CAD tools are used, when in the design process they are implemented, the justification for their use from the students' perspectives, the actual knowledge gained from their use, the impact on the final designed artifact, and the contributions of any sketches generated. At each design step, comparisons are made between CAD and sketching. The students implemented CAD tools at the onset of the project, generally failing to realize gains in design efficiency or effectiveness in the early conceptual phases of the design process. As the design became more concrete, the team was able to recognize clear gains in both efficiency and effectiveness through the use of computer assisted design programs. This study is augmented by interviews with novice and experienced industry users and academic instructors to align the trends observed in the case study with industry practice and educational emphasis. A disconnect in the perceived capability of CAD tools was found between novice and experienced user groups. Opinions on the importance of sketching skills differed between novice educators and novice industry professionals, suggesting that there is a change of opinion as to the importance of sketching formed when recent graduates transition from academia to industry. The results suggest that there is a need to emphasize the importance of sketching and a deeper understanding as to the true utility of CAD tools at each stage of the design process.

Abstract:

Computer-aided design (CAD) is rapidly becoming an indispensable tool for landscape architects and designers. This has created the need for a simple-to-use, inexpensive, and readily available configuration for introducing computer-aided design on a limited budget to landscape students. This introduction to computer-aided landscape design can be accomplished easily and accurately using the 512K Macintosh computer and the software package MacDraw. Techniques are reported for shading, layering, and customizing plant and groundcover symbols, allowing a personal touch that is lacking in some more-advanced CAD packages. Computer-generated pages can be collaged to make full-sized landscape drawings, which are then copied onto reproduction vellum. In this manner, the design capability is not limited by the size of the minter. This design configuration is currently in use and was used to generate the design and the symbol illustrated.

Abstract:

SUMMARY The use of computer-aided design/computer-aided manufacturing (CAD/CAM) dentistry has triggered novel approaches to restoring teeth in ways that increase efficiency, improve esthetics, and conserve tooth structure. Endodontically treated mandibular incisors offer a challenging restorative opportunity due to the small amount of natural tooth structure and the required amount of reduction needed for restorative material. The case presented demonstrates how to leverage chairside CAD/CAM technology to restore a discolored and fractured endodontically treated mandibular incisor without the use of a post and core and completing the restoration in a single visit.

Abstract:

The study evaluated in vitro two-body wear and surface roughness of the recently introduced CAD/CAM dental materials. Pin-on-disk design was set against each other horizontally at a fixed distance with 5 kg (49 N) in distilled water. CAD/CAM materials used were: Feldspathic ceramic (Vitablocks Mark II), lithium disilicate (IPS e.max CAD), hybrid ceramic (Vita Enamic) and zirconia-reinforced glass ceramic (Vita Suprinity PC). Wear evaluation before and after the chewing cycles were performed by two approaches: weight and vertical height measurements. The surface roughness of the tested materials was further evaluated after chewing cycles. One-way ANOVA showed significant differences among the mean values of the materials’ vertical height loss and surface roughness (P < 0.05). However, in weight loss, no statistical differences were observed. The highest vertical height loss was observed in feldspathic ceramic while the lowest vertical height loss was recorded in zirconia-reinforced glass ceramic. Feldspathetic ceramic demonstrated the least surface roughness among all the groups. Feldspathic ceramic had a significantly least wear resistance and surface roughness, while Zirconia reinforced glass ceramic (VITA Suprinity PC) had a significantly higher wear resistance and acceptable surface roughness among tested groups.

Abstract:

ABSTRACT Objective: This study presents a comparative analysis of the color stability of computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated provisional restorations with those of conventional restorations. Materials and Methods: Three different provisional restorative materials (Systemp C&B, 3M Protemp 4, and Telio CAD) were inspected for their color stability using four solutions (Pepsi, coffee, tea, and distilled water). All samples used were fabricated using A1 shade by following the manufacturer's instructions. Color assessment was performed using CIELAB system and a colorimeter. After baseline color measurement, color assessments were done weekly after immersion in specified solutions. Triplicate readings were taken for every sample and the mean value of the color coordinates (L*), (a*), and (b*) were recorded at baseline, week 1, week 2, week 3, and week 4. The data within different groups were compared statistically using analysis of variance (⍺ = 0.05). Results: Overall, the highest color stability was found in CAD/CAM material, followed by Protemp and SystempC&B. It was also observed that the maximum color variation was observed in case of coffee, followed by tea and Pepsi. Conclusions: CAD/CAM provisional material (Telio CAD) showed better color stability compared to conventional materials (Protemp 3M ESPE and SystempC&B Ivoclar Vivadent). CAD/CAM provisional materials are recommended for long-term temporization procedures. This is attributed to the prepolymerization, higher monomer conversion, and minimal preparation errors in CAD/CAM materials.
