We outline a procedure for implementing a virtual CNC lathe prototype using software for creating virtual environments. The prototype constructed focus on the lathe’s interlocking system (its functionality) and on its geometric model (its physical design). This project allowed us to identify the possibilities and limitations of applying current Virtual Reality technology for virtual prototyping...

Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and alternative process routes. In this dynamic model, we attempt to resolve the problem of integrated family (par...

This paper describes the initiation of our project to study three-dimensional navigation through manufacturing knowledge domains suitable for training. In summary we are organizing and representing knowledge from the NIST Manufacturing Engineering Laboratory (MEL) and associating that knowledge with virtual objects within a virtual, three-dimensional environment. We are using the MEL Shop as a ...

The emergence of Cellular Manufacturing Systems has resulted in signific ant productivity improvement in manufacturing systems. The Cellular Manufacturing System has received wide attention and is well documented in the literature. This study demonstrates the use of Decision Support Systems (DSS) to cellular manufacturing.

This paper presents a mathematical model for designing cellular manufacturing systems (CMSs) solved by genetic algorithms. This model assumes a dynamic production, a stochastic demand, routing flexibility, and machine flexibility. CMS is an application of group technology (GT) for clustering parts and machines by means of their operational and / or apparent form similarity in different aspects ...

Historically, manufacturing engineering education has focused on teaching mathematical models using simplifying assumptions that can mask the realities of complex manufacturing systems. Recent pedagogical approaches to manufacturing education have focused on developing a more holistic view of the manufacturing enterprise. In this paper, we describe the contents and development methodology of a ...

In order to implement the cellular manufacturing system in practice, some essential factors should be taken into account. In this paper, a new mathematical model for cellular manufacturing system considering different production factors including alternative process routings and machine reliability with stochastic arrival and service times in a dynamic environment is proposed. Also because of t...

The research area " Virtual Manufacturing (VM) " is the use of information technology and computer simulation to model real world manufacturing processes for the purpose of analysing and understanding them. As automation technologies such as CAD/CAM have substantially shortened the time required to design products, Virtual Manufacturing will have a similar effect on the manufacturing phase than...
