Abstract:

The development of pulp and paper production and technology is reviewed with special emphasis on its influence on the waste water discharge. The chemical pulping methods are in a rapid development phase, including novel processes as well as substantial changes taking place in the kraft pulping process. Due to the changing chemical pulping and bleaching practice, the chlorinated organic compounds in the effluent will lose their importance. Research should be focused on the effects of new contaminants introduced in chlorine-free bleaching, and on the natural substances occurring in wood that are causing the remaining toxicity of the effluent from both mechanical and chemical pulp mills. Enhanced recycling of post-consumer paper and board leads to an increased number of deinking plants with new types of discharges. Closure of process water loops are also expected in the near future, which may totally eliminate the process water discharges from modern mills.

Abstract:

Globally, own store brands or private labels are rapidly gaining share at the cost of manufacture brands. In India, where the share of organised retail is minuscule, manufacture brands still dominate. With the retail sector poised for growth, national brand manufacturers will have to contend with competition within distribution channel, which calls for revised marketing strategy locally, to thwart the threat of the private label in a store. The phenomenon also offers national brand manufacturers the opportunity to service the production needs of the private labels efficiently. The problem is India's internet-savvy consumers aren't as convinced about Private labels as their global counterparts. Consumers may be happy with the quality of private label when it comes to kitchen towels and staples like wheat flour but are wary when it comes to buying a store version of, say, baby food or shampoo. The paper has also discussed the different types branding strategies used by retailers in the developing countries. The manufacturer brands have an advantage relative to own brand where symbolic association and/or product innovation are important to customers. Conversely, where symbolic associations and product innovations are less important there is an opportunity for retailers to compete successfully with manufacturer brands if they can demonstrate comparable product quality and provide value or money. This paper deals with the power of private label in modern retail market.

Abstract:

In a closed-loop supply chain (CLSC), the right alliance can help manufacturers better manufacture green products and make more profits. Choosing the most suitable alliance partner is also critical for manufacturers. In regard to product greenness and recycling competition, this paper considers the CLSC comprised of a dominant manufacturer, a retailer, and a third-party recycler. Based on the Stackelberg game and equilibrium analysis, we discuss the optimal supply chain decision-making under four different models. Then, in order to ensure supply chain (SC) members’ enthusiasm to participate in the alliance, we design a profit distribution method to distribute the total profit to SC members. The results show that manufacturer’s optimal alliance decision is related to the degree of recycling competition. When less than the threshold, C alliance(the manufacturer make an alliance with the retailer and the third-party recycler at the same time) is optimal, otherwise, MR alliance(the manufacturer and the retailer make an alliance ) is more beneficial for the manufacturer.

Abstract:

As to spiral groove grinding, a formed wheel was needed to be designed and manufactured conventionally based on envelope theory, and then this wheel was used to grind the specified spiral groove. This paper tried to find the other way to manufacture the specified spiral groove with common dish wheels. A generic model for groove grinding is presented in this paper, the groove geometries can be calculated under certain grinding parameters. The relations between the grinding parameter and groove geometries were studied numerically. To manufacture the specified spiral groove with common dish wheels and no special wheel is needed to be designed. This method offers a new way for the spiral groove grinding. This technology also makes the spiral groove virtual machining possible. The technology is also a real DFM (Design For Manufacture), because the design process for spiral groove is the process for selecting manufacture parameters.

Abstract:

An innovative approach to the manufacture of impulse turbine blades using rapid prototyping, fused decomposition modelling (FDM), is presented in this paper. These blades were designed and manufactured by the Wave Energy Research Team (WERT) at the University of Limerick for the experimental analysis of a 0.6m impulse turbine with fixed guide vanes for wave energy power conversion. The computer aided design/manufacture (CAD/CAM) package Pro-Engineer 2000i was used for three-dimensional solid modelling of the individual blades. A detailed finite element analysis (FEA) of the blades under centrifugal loads was performed using Pro-Mechanica. Based on this analysis and FDM machine capabilities, blades were redesigned. Finally, Pro-E data were transferred to an FDM machine for the manufacture of turbine blades. The objective of this paper is to present the innovative method used to design, modify and manufacture blades in a time and cost effective manner using a concurrent engineering approach.

Abstract:

The electric motor components are manufactured through the additive process of fused filament fabrication in order to verify the functionality of the electric motor assembly. This process was chosen due to the advantages it confers: fast obtaining of components, low manufacturing costs, no tools required for processing or for moulds manufacturing. Through the fused filament fabrication process, parts with complex geometries, which cannot be obtained by classical machining, can be manufactured. Due to the above-mentioned advantages, this technology is extremely useful for the manufacture and testing of prototypes. The paper aims to manufacture components of a brushless electric motor in order to verify the assembling compatibility and manufacturing accuracy.

Abstract:

In some cases the spatial cam is manufactured with a cutter whose diameter is smaller than that of the roller of cam mechanism, which is defined as nonequivalent manufacture method in the paper. By the analysis for manufacture of contact lines between the cam and the roller, it is indicated that errors caused by the different directions of normal vector are unavoidable for the nonequivalent manufacture method. In order to find the best tool axis vector to minimize the machining error, this paper realized the nonequivalent machining of spatial cam surfaces using the NC flank milling method and proposed a new generation algorithm of the tool path based on NURBS. The NURBS ruled surface of tool axis trajectory is confirmed based on the least square optimization method and the machining error model is given. At last, a numerical calculation and simulation example is described to verify the effectiveness of the algorithm proposed in the paper.

Abstract:

One of the key application areas of Single Point Incremental Forming is in the manufacture of parts for bio-medical applications. This paper discusses the challenges associated with the manufacture of cranio-facial implants with extreme forming angles using medical grade titanium sheets. While on one hand, the failure wall angle is an issue of concern, the parts also need to be manufactured with accuracy at the edges where the implants fit into the human body. Systematic steps taken to overcome these challenges, using intelligent intermediate part design, feature analysis and compensation, are discussed. A number of case studies illustrating the manufacture of accurate parts in aluminium, stainless steel and titanium grade-2 alloy are discussed.

Abstract:

Tool manufacture and use are observed not only in humans but also in other animals such as mammals, birds and insects. Manufactured tools are used for biomechanical functions such as effective control of fluids and small solid objects and extension of reaching. These tools are passive and used with gravity and the animal users' own energy. From the perspective of evolutionary biology, manufactured tools are extended phenotypes of the genes of the animal and exhibit phenotypic plasticity. This incurs energetic cost of manufacture as compared to the case with a fixed tool. This paper studies mechanics and energetics aspects of tool manufacture and use in non-human beings. Firstly, it investigates possible mechanical mechanisms of the use of passive manufactured tools. Secondly, it formulates the energetic cost of manufacture and analyses when phenotypic plasticity benefits an animal tool maker and user. We take a synthetic approach and use a controlled physical model, i.e. a robot arm. The robot is capable of additively manufacturing scoop and gripper structures from thermoplastic adhesives to pick and place fluid and solid objects, mimicking primates and birds manufacturing tools for a similar function. We evaluate the effectiveness of tool use in pick-and-place and explain the mechanism for gripper tools picking up solid objects with a solid-mechanics model. We propose a way to formulate the energetic cost of tool manufacture that includes modes of addition and reshaping, and use it to analyse the case of scoop tools. Experiment results show that with a single motor trajectory, the robot was able to effectively pick and place water, rice grains, a pebble and a plastic box with a scoop tool or gripper tools that were manufactured by itself. They also show that by changing the dimension of scoop tools, the energetic cost of tool manufacture and use could be reduced. The work should also be interesting for engineers to design adaptive machines.

Abstract:

Coriolis mass flowmeters are highly customized products involving high-degree fluid-structure coupling dynamics and high-precision manufacture. The typical delay from from order to shipment is at least 4 months. This paper presents some important design considerations through simulation and experiments, so as to provide manufacturers with a more time-efficient product design and manufacture process. This paper aims at simulating the fluid-structure coupling dynamics of a dual U-tube Coriolis mass flowmeter through the COMSOL simulation package. The simulation results are experimentally validated using a dual U-tube CMF manufactured by Yokogawa Co., Ltd. in a TAF certified flow testing factory provided by FineTek Co., Ltd. Some important design considerations are drawn from simulation and experiment. The zero drift will occur when the dual U-tube structure is unbalanced and therefore the dynamic balance is very important in the manufacturing of dual U-tube CMF. The fluid viscosity can be determined from the driving current of the voice coil actuator or the pressure loss between the inlet and outlet of CMF. Finally, the authors develop a simulation application based on COMSOL’s development platform. Users can quickly evaluate their design through by using this application. The present application can significantly shorten product design and manufacturing time.

The last decade has seen strong interest from high-volume manufacturers such as the automotive industry in the development of processes which provide cost effective routes to the manufacture of components in fibre-reinforced composite materials. This paper considers one family of processes that have been targeted as offering a solution—that of resin transfer moulding (RTM)—and reviews the findings of work based at the University of Nottingham. The mechanisms involved are examined together with the variants on the basic process and the implications for high-volume production. Consideration is given to process technology, materials and the relationship between design and manufacture. A route to high-volume manufacture based upon computer aided engineering is proposed.

Abstract:

Honeycomb paper core stretching is an important process in paper core manufacture because the performance and the quality of paperboard are greatly enhanced when the honeycomb hole is stretched to a regular hexagon structure. In view of the above, first the finite element method is used to compare the mechanical performances of honeycomb paperboards of different aperture ratios, and the aperture ratio, which has an important influence on the performance of the honeycomb paper, is explained. Next, a paper core stretching simulation is carried out by means of the dynamic software; thus the variation trend of the stretching force, the stretching speed, and the lateral shrinkage needed in paper core manufacture of different specifications can be obtained. This research can provide useful instruction in the actual manufacture of honeycomb paper core.

Abstract:

Abstract Effects of alkali swelling of kraft pulp fibers and the order of alkali swelling and beating treatments on paper bulk and paper strength were evaluated in terms of NaOH concentration in order to produce high bulk sheet (i. e., high porous and low density sheet). Effects of replacement of part of furnish with the alkali swollen pulp on paper properties were also investigated. It was found that alkali swelling of pulp fiber can increase the bulk of handsheet. NaOH concentration and beating treatment influenced paper bulk and paper strength. Alkali swollen pulp without beating showed the highest handsheet bulk. The paper bulk of alkali swollen pulp with pre-beating was higher than that with post-beating. Paper strength decreased with increasing the bulk of handsheet. In addition, replacement of part of furnish with alkali swollen pulps increased paper bulk, adversely decreasing paper strength. The highest improvement in paper bulk was achieved with the addition of alkali swollen SwBKP without beating.

Abstract:

Abstract This paper offers a re-evaluation of the significance of porcelain during the Yuan dynasty by analyzing a type of ceramics known as luanbai or shufu wares. These matt white porcelains, sometimes inscribed with the characters shu and fu, have generally been seen as official wares, manufactured on the orders of the highest echelons of the Yuan central government and classified as high-quality luxury wares associated with the imperial court. This paper proposes that this conventional interpretation is misleading. Instead of understanding luanbai wares as part of the narrative of ceramics manufacture and the history of porcelain, I explore their relevance by situating them in the context of Yuan-dynasty material culture more broadly, court-sponsored craft manufactures, and the practice of inscribing objects. This approach reveals a different story, highlighting the absence of court control over ceramic production, the ensuing freedom to experiment locally with new ceramic production methods, and the significance of the demands of consumers in territories outside Yuan China.

Abstract:

Inventory management is one of important issues in the manufacture system. Thus, this paper proposes a new fuzzy approach to solve the inventory management problems in the manufacture system. In the past, few papers discussed the square roots of fuzzy number. The square roots of fuzzy number can be applied to solve the optimal inventory quantity problems in the fuzzy manufacture system. This paper first proposed the square roots of fuzzy number. Finally, the square roots of fuzzy number are applied to obtain the optimal order quantity for the fuzzy backorder inventory model in the manufacture system.

Abstract:

Fibre-reinforced polymers (FRP) have attracted much interest within many industrial fields where the use of 3D printed molds can provide significant cost and time savings in the production of composite tooling. Within this paper, a novel method for the manufacture of complex-shaped FRP parts has been proposed. This paper features a new design of bike saddle, which was manufactured through the use of molds created by fused deposition modeling (FDM), of which two 3D printable materials were selected, polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS), and these molds were then chemically and thermally treated. The novel bike saddles were fabricated using carbon fiber-reinforced polymer (CFRP), by vacuum bag technology and oven curing, utilizing additive manufactured (AM) molds. Following manufacture the molded parts were subjected to a quality inspection, using non-contact three-dimensional (3D) scanning techniques, where the results were then statistically analyzed. The statistically analyzed results state that the main deviations between the CAD model and the manufactured CFRP parts were within the range of ±1 mm. Additionally, the weight of the upper part of the saddles was found to be 42 grams. The novel method is primarily intended to be used for customized products using CFRPs.

Abstract:

In industrial engineering and management, to know the demand quantities of downstream manufacturer is an important issue which can help the upstream suppliers to control and predict the level of manufacturing process. The supplier may encounter competitors who also provide the materials or product to the same downstream manufacturer. This paper proposes a stochastic model to forecast the total demand of the manufacture company with characteristic function. This model can be used to detect the quantities which are provided from other competitors to the same manufacturer.

Abstract:

Our presentation develops the study of cement mortars manufactured with melamine waste, either in the form of powder or cellulose paper, taken from the industrial production of particle boards, characterizing all of their properties and comparing them with traditional cement mortars. The objective is to determine in what way the addition of melamine powder and melamine paper will modify traditional mortar, once these materials have been subjected to a polymerization process under pressure and under increased temperature, in order to assess the possibility of using these new materials for applications in the construction industry. The behaviour of mortar in the fresh state is studied, determining the variations produced with the addition of melamine powder and melamine paper on the workability and the on-site use of these mortars. Likewise, their mechanical properties under flexion, compression, and adherence to a ceramic surface are studied and compared with those obtained from the reference mortar. Water absorption by capillary action and vapour permeability are also studied, in order to understand the interaction of the polymerized melamine in the capillary network of the mortar. Dosages were prepared for a reference mortar and a further two series of mortars with different quantities of melamine powder and melamine paper, together with cement, sand and water. In this first phase, the use of additives in the mixtures was not considered. The process of selecting the materials and the dosage criteria of the mixtures are subsequently described. The results of the study show that the use of powder melamine and paper cellulose melamine can be used to manufacture mortars with properties that are equivalent to traditional mortars, although further studies with greater precision will be needed on the contribution of the melamine polymerization process to the internal structural cohesion of the mortar.

Abstract:

Due to the reasons of manufacture cost and mechanical efficiency, the gear transmissions for electric vehicles are helical gear reducers. For electric vehicles, the reduction ratios are required to be 11~30 and their gear reducers are helical gear reducer with two gear pairs. This paper focused on the design and prototype manufacture of helical gear reducers with two gear pairs. First, according to the kinematic requirements of electric vehicles, their reduction ratios were derived. Then, based on the involute theorem, the gear data of helical spur gear pairs we obtained. Finally, according to the gear data, its corresponding engineering drawings were accomplished and its corresponding prototype was manufactured. The results of this paper can be used as reference for engineers to design the gear reducers for electric vehicles.

Abstract:

As to spiral groove grinding, convertionally was based on envelope theory, a formed wheel was needed to be designed and manufactured, and then this wheel was used to grind the specified spiral groove. This paper tried to find the other way to manufacture the specified spiral groove with common disc wheel or dish wheels. A generic model for groove grinding is presented in this paper. With the model, the groove geometries can be calculated under certain grinding parameters. The relations between the grinding parameter and groove geometries were studied numreically. A test was done and the results proved the model is correct. This technology make the spiral groove virtual machining possible. The technology is also a real DFM (Design For Manufacture), because the design process for spiral groove is the process for selecting manufacure parameters.

Abstract:

This paper aims to contribute to developing a new approach related to the viability concept. This paper also demonstrates the relevance of change from the 'object' concept to the concept of 'relation' for organizational design. A system, or a viable unit in a relational sense, cannot be separated from its circumstances: what surrounds it must remain with it. What is referred to as external is not an entity apart from the unit, and, for that reason, the definitions of 'medium' and 'environment' that are being used do not correspond to these criteria. In the present context, the value generation process is mainly located in the strategic role of intangibles; as noted earlier, value propagation necessarily implies the understanding that this process is distanced from traditional physical rules whenever there emerges a relational field that allows its implementation. Emergent design or warp network is fundamentally a relational process developed from co-autonomy upon a heterarchical operational structure.

Abstract:

There are currently various technologies for the manufacture of warm mix asphalts (WMA). This paper presents the possibility of using a natural zeolite to manufacture WMA as an alternative to existing synthetic products for the manufacture of this type of mixture. Moreover, the possibility of manufacturing WMA with the addition of recycled asphalt pavement (RAP) using natural zeolite as the basis of a warm mix technology was evaluated. Firstly, asphalt mixtures were manufactured at three different temperatures (145 °C, 135 °C, and 125 °C) with different percentages of natural zeolite to determine the temperature and the optimum content for the manufacture of WMA. Then, the zeolite moisture content and its release over time were determined at different temperatures, and its distribution in the binder was checked at different concentrations by scanning electron microscopy and fluorescence. Next, with the optimum zeolite content, the addition of RAP between 10–30% in the WMA at the same three manufacturing temperatures was evaluated. Two types of compaction were used: the impact and gyratory compactions. The Marshall parameters were evaluated for all the designed mixtures. The results indicated that the manufacture of WMA with the addition of natural zeolite is feasible, and depending on the required mixing temperature, recycled WMA with different percentages of RAP can be obtained.
