Aspects of computer-aided fixture design

Abstract Computer software developed for the design of a modular fixture device for use in a computer-integrated manufacturing system is described. The software can guide a designer towards the optimum design of a fixture device by taking account of external forces and their positions, thus preventing obstacles from being placed in the cutting path, or the deflection of a workpiece. The flexibility of the modular system, which is known as SPUD, has been utilized and supported by the Computer-Aided FIXture Design (CAFIXD) system, which offers a high level of automation within the manufacturing process, and the economic benefits which a flexible manufacturing system brings.
