A new methodology is presented to generate all of the assembly sequences with any predetermined line configuration wherein k 1 , K 2 ,..., kN parts, or subassemblies, are to be assembled at stations 1, 2,..., N, respectively. The methodology extends the renders current approaches in sequence generation for a binary assembly process applicable to a k-ary assembly process by considering: (i) multiple joints between two parts or subassemblies; and (ii) mutual blocking among several parts or subassemblies. This methodology is based upon proposed k-piece graph and k-piece mixed graph approaches for the assemblies, the former without and the latter with assembly precedence relationship. With the k-piece graph and k-piece mixed graph approaches, all of the feasible subassemblies can be identified, and all of the sequences for a predetermined assembly line configuration are iteratively generated. A case study is presented to illustrate the advantages of the presented method over the state-of-the-art approaches in assembly sequence generation.

The paper have conducted a study on the cost calculation of spray component mould manufacturing process. In general, it is the present state that calculating machining time and cost for a unit process in mould manufacturing process depends on past experiences. In other words, it does not go beyond the level of computing and management by estimation based on the data conducted in the past. Accordingly, in the development of mould and new products tried for the first time, the cost calculation is not reasonable and thus a lot of time is needed. That is to say, not being able to actively and reasonably respond to the needs of the market that are changing every moment, the loss of management and money due to losing opportunities is frequently taking place. In this context, it have developed and applied a system that can reasonably calculate the cost by taking account of machining time calculation theory, machine, tool, material and working environment. As a result, calculating the time needed for a unit process in mould manufacturing process is possible, and it is possible to classify major processes and suggest alternatives in management. The system developed in this study used Visual Basic Language and SQL database under Windows environment.

This paper presents a successful off-line optimisation case study of a sheet-metal press line for the automotive industry. The proposed off-line optimisation method results not only in increased production rate but also in obtaining smoother material handling motions. The off-line optimisation method contains two parts. The first part is a parameter study, combining factorial design with production line simulation including emulated control systems and resulting in a simplified performance model based on multiple linear regression. The second part is an optimisation on the simplified performance model using the Nelder Mead simplex method aiming at production optimisation. Due to the complexity in a modern production line, it is not possible to create a useful model representation of the entire control system code/function. Therefore, the proposed optimisation method is based on using production line simulation including emulated control systems with the real IEC 61131-3 control code. Our approach in this work is a parameter variation strategy for optimisation, i.e. adjusting the control system parameters in the same way as the line operators do, and not changing any control strategy.

This paper introduces a design method for self reproducing hardware. Self assembly or self organization is an attractive subject in a variety of research fields such as mechanics, chemistry and physics. Especially, if hardware self reproduction is realized, revolutionary changing will occur in the industrial world. Hardware self reproduction is a kind of self assembly to obtain the same kinds of hardware as the objective hardware from the simple elements automatically. It seems to us that the best case of success regarding self reproducing is the method of the deoxyribonucleic acid (DNA), that is, semiconservative replication. We, therefore, aim at developing the design method of self reproducing hardware by imitating the semiconservative replication of DNA. Based on the aspects of the semiconservative replication of DNA, we classified the interaction of the hardware and elements into three modes, namely Assembly mode, Connection mode and Division mode. We show that we can realize self reproduction of hardware by combining these three modes. To clarify the effectiveness of the proposed method, we also show the concrete examples of the self reproducing hardware. The proposed self reproduction can be realized by controlling only the temperature and stirring in the environment.

Bottlenecks in a production line have been shown to be one of the main reasons that impede productivity. Correctly and efficiently identifying botdeneck locations can improve the utilisation of finite manufacturing resources, increase the system throughput, and minimize the total cost of production. Current bottleneck detection schemes can be separated into two categories: analytical and simulation-based. For the analytical method, the system performance is assumed to be described by a statistical distribution. Although an analytical model is good at long term prediction, this type of model is not adequate for solving the bottleneck detection problem in the short term. On the other hand, the simulation-based method has disadvantages, such as long development time and decreased flexibility for different production scenarios, which greatly impede its wide implementation. Because of all these problems, a data driven bottleneck detection method has been constructed based on the real-time data from manufacturing systems. Using this new method, bottleneck locations can be identified in both the short term and long term. Furthermore, the proposed data driven bottleneck detection method has been verified using the results from both the analytical and simulation methods.

We present a deterministic scheduling approach for flexible assembly lines and robotic workcells based on n-dimensional collision functions. By collision functions, the different process plans which include parallel robot operations are correlated and coordinated. Feasible schedules only exist for zero correlation. Coordination parameters are the release time intervals for each individual process. The scheduling algorithms rest upon an extended Gantt chart representation for the process plans which model the exclusive use of space resources.

This paper presents the results of developing an industrial prototype of a micro-gripping system. The system is based on the liquid solidification gripping principle. Part handling actions are realized by changing the gripping intermediate between its liquid phase and solid phase. The current research aims to bring the understanding of the gripping principle as well as the design of the gripping system one step closer to industrial application. The paper describes the physical principle of the gripping method and the design of an industrial prototype gripper. Tests of the gripping system show that a cycle time of 1.4 s can be achieved with 90% reliability for gripping a part with good heat conductivity (17 consecutive gripping actions in one process run, result was concluded after several runs). A cycle time of less than 1s can be achieved on gripping parts with lower heat conductivity.

The research in mini, micro and desktop factories originates from early 90's and has continued since then by developing the technological basis and different technological building bricks and applications in the field of high-precision manufacture and assembly of future miniaturized and micro products. This has paved the way to mini, micro and desktop factories which are seen as one potential solution for that kind of production by improving space, energy and material resource utilization and answering to the needs of design for postponement and customer-close customization and personalization. The research efforts done during these years are now increasingly leading also to commercialization and real industrial applications. The objective of this paper is to present an overview of the international microfactory research and to introduce in more detail the modular microfactory concept developed in the M4-project.

The contour of a special part commonly consists of line and arc segments (non-micro segments), as well as continuous micro line segments (micro segment groups) that precisely approach the complicated or irregular portions of that contour. For precise machining of the contour, especially for those complicated or irregular portions, the real-time generation of motion command for X and Y axes should be decided according to the characteristics of the contour. Thus, in this paper, a look-ahead based adaptive motion control algorithm is presented. The structure of the whole motion control algorithm is analyzed at first, which guarantees real-time machining. In addition, concrete adaptive motion control algorithms for both non-micro segments and micro segment groups are elaborated. The motion control algorithm predicts the variation of the curvature of the coming trajectory so that adaptively determining whether to accelerates feedrate to enhance machining efficiency or decelerates the feedrate to guarantee machining precision. Finally, both simulation results and experimental results are presented to verify the efficiency of the proposed motion control algorithm.

A methodology for decomposition of material removed volumes so called Delta Volumes according to the natural sequences of machining is proposed. Tool classification and coding system for automatic characteristics and parameter extraction is presented. Algorithms for identification of major access directions and machining complexity and rules determining operations and tools for roughing and finishing are presented. This article suggests a technique that generates machining operation sequences with appropriate combinations of tool and machine directly from the 3D model of a part and a given block.
