Manufacturing cycle time (the time that elapses from work order release to completion) affects the cost of developing and manufacturing a product. However, most cost models consider only the setup and processing times and ignore the move times and queue times, which form most of the manufacturing cycle time. This paper discusses the economic impact of manufacturing cycle time. It presents metho...

This paper presents an overview of a neutral reference architecture for integrating distributed manufacturing simulation systems with each other, with other manufacturing software applications, and with manufacturing data repositories. Other manufacturing software applications include, but are not limited to, systems used to: 1) design products, 2) specify processes, 3) engineer manufacturing s...

As a new approach, grid technology is rapidly used in scientific computing, large-scale data management, and collaborative work. But in the field of manufacturing, the application of grid is just at the beginning. The paper proposes the concept of manufacturing. The needs, definition and architecture of manufacturing gird are discussed, which explains why needs manufacturing grid, what is manuf...

An integrated process planning system for layered manufacturing (LM) reduces the time between design and part fabrication and improves the quality of the final part. Process planning for most LM processes includes part orientation, support structure generation, slicing, and path planning. In this paper we describe an integrated process planning system we are developing. Our software accommodate...

Although separation of product design from manufacturing capabilities is a major advantage of Additive Manufacturing (AM), the impact of AM is not only limited to the design and manufacturing stages. In addition to the freedom of design such as elimination of design constraints, material saving, and free complexity, AM offers other potential benefits to the manufacturing industry as well. One o...

Agent based distributed manufacturing control and scheduling systems are subsets of new manufacturing systems. Multi agent systems (MAS) not only drive design and engineering control solutions but also influence flexibility, agility, and re-configurability, which makes MASs a better centralized systems than its traditional counterparts. However, implementation of all MASs in the real factories ...

This paper discusses the informational requirements of layered manufacturing (LM). The most common industrial use of LM today is for rapid prototyping, but we take a wider view of it as a flexible fabrication technology. Its use in building functional metallic parts under computer control has already been demonstrated in the research context. Commercial LM machines for building production parts...

rapid prototyping (rp) is a technique of manufacturing parts by the additive layer manufacturing technology; where, a three-dimensional (3d) model created in a computer aided design (cad) system is sectioned into 2d profiles, which are further constructed by rp layer by layer. its use is not limited to industrial or engineering fields and has extended to the medical field for the manufacturing ...

“Passive” convergence of knowledge and technologies has had an important effect on manufacturing development. Manufacturing enterprises have evolved for the most part as centralized and concentrated urban complexes, primarily driven by the need to minimize manufacturing costs. Examples include the automobile industry of southeastern Michigan and the electronics manufacturing complex in Shenzhen...

tire manufacturing industry has a history of more than half a century in iran, where 14 thousand workers are employed. the old and semi-automated processes equipment, backward technology, and raw materials impurity lead to significant exposures to occupational carcinogens such as benzene. this study was to assessment of benzene exposures and evaluation the resulting cancer risk in two tire-manu...
