Abstract Virtual reality (VR) refers to an immersive, interactive, multi-sensory, viewer-centered, three-dimensional (3D) computer generated environment and the combination of technologies required to build such an environment (Cruz-Neira, 1993). Related to problems of engineering design and manufacturing, this new technology offers engineers the ability to work with computer models in a three-dimensional, immersive environment. This paper describes a virtual reality application where the results of a discrete event simulation of a manufacturing cell are integrated with a virtual model of the cell to produce a virtual environment. The program described in this paper, the VR Factory, allows the user to investigate how various changes to the manufacturing cell affect part production. This investigation is performed while immersed in a computer generated three-dimensional representation of the cell. This paper describes the creation of the VR model of the manufacturing cell, the animation of the environment and the implementation of the results of the discrete event simulation.

Abstract The purpose of this research is to develop a methodology and a prototype system that allows the integration of product design and manufacturing planning. The task is achieved through an integrated CAD-CAPP-CAFP# environment. The system consists of three major modules, namely, Feature Analyzer, Process Planner and Fixture Planner. The manufacturing information of a part required for process and fixture planning is extracted from the 3-D geometric model and the 2-D engineering drawing, thereby both geometric and non-geometric attributes of a part can be obtained. An integrated approach to process and fixture planning is adopted to ensure that the process plan for a part is generated on the basis of a workable fixture plan. The approaches to feature analysis and to integrating process and fixture planning are introduced.

This paper describes the work that has been done with an intention to integrate the design and manufacturing functions by developing a feature-based 'front-end' to a CAD solid mode11er. This enables designers to express their concepts in terms of manufacturing features and processes, and simultaneously captures this information in a form suitable for an outline process plan.

Manufacturing Applications

Abstract Virtual Reality has been used for several years by architects to bridge the gap between their vision of the product and the finished product. Many of these applications use VR on a completed design and allow minor modifications to the design in the VR environment. This paper presents a feasibility study which was conducted to evaluate the accuracy of VR systems when used for conceptual design and in general, for engineering applications. A truck cab interior was modeled in a virtual environment and several ergonomic tests were performed in this virtual environment. The same tests were performed in a physical prototype of the truck cab and results of the two tests were compared. The virtual reality hardware and software systems used, the design evaluation scenario and the results of the tests are presented.
