The concept of Virtual Computer-Integrated Manufacturing (VCIM) has been proposed for one and a half decade with purpose of overcoming the limitation of traditional Computer-Integrated Manufacturing (CIM) as it only works within an enterprise. VCIM system is a promising solution for enterprises to survive in the globally competitive market because it can exploit effectively locally as well as g...

This paper addresses the need to generate functionally large geometries/objects for layered manufacturing machines. Novelty is found in the translation from an initial shape in CAD to subdivision as interlocking objects that are further subdivided into slicing layers using traditional layered manufacturing software. Translation from an initial shape to individual component geometry is guided by...

With the development of computer-aided design/computer-aided manufacturing (CAD/CAM) technology, it has been possible to reconstruct the cranio-maxillofacial defect with more accurate preoperative planning, precise patient-specific implants (PSIs), and shorter operation times. The manufacturing processes include subtractive manufacturing and additive manufacturing and should be selected in cons...

In the manufacturing industry, they are using various concepts and solutions in order to reduce time and costs in the product development. This article introduces an approach that enables Virtual Engineering and links engineering applications with Virtual Reality (VR) solutions. Thus an environment is provided to implement virtual design reviews and enable the application of virtual prototyping...

Much better results in terms of perforniancekost ratio and reliability may be achicvcd if largc machines and structures are replaccd by swarms of smaller ones capablc of co-opcrating on spccificd tasks and negotiating ~ i t h each other what to do next. Armadas of small communication satellites are being dcsigncd to replace largc geostationary units and swarms consisting of hundreds of miniatur...

Cellular Manufacturing (CM) has been emerged as a strong approach for improving operations in batch and job shop environments. In cellular manufacturing, Cell formation, static layouts, dynamic layouts are the prime areas for achieving the optimal cellular layout for any problems. In this paper it is decided to review the recent research work in this particular area and to project the effective...

One of the designs of cellular manufacturing systems (CMS) requires that a machine population be partitioned into machine cells. Numerous methods are available for clustering machines into machine cells. One method involves using a similarity coefficient. Similarity coefficients between machines are not absolute, and they still need more attention from researchers. Although there are a number o...

This paper addresses the formal specification and description of manufacturing systems. It is considered the use of SDL (Specification and Description Language), a standard FDT (Formal Description Technique), to model the behaviour, data and structure aspects of a manufacturing system. SDL was originally developed for telecommunication systems (protocol specification and data processing). The a...

Manufacturing process of gear is fairly complicated due to the presence of various simultaneous motions of the cutter and the job. In this paper, an attempt is made to generate meaningful design data for a spur gear and the corresponding rack form cutter necessary for the manufacturing process. Using these information, solid models for the cutter and blank are developed and finally gear-manufac...
