Abstract

This paper describes a variant approach to computer-aided tool engineering and its application to a green sand casting foundry. The primary goal of the project was to develop methods for reducing the lead time and cost required to bring casting jobs into production. A general approach integrating the concepts of group technology (GT), group tooling, and numerical control (NC) machining into a computer-aided engineering system to generate patterns and core boxes for castings is presented. The steps used in implementing the approach-analysis of requirements, GT coding and classification, development of the tooling concepts, determining logic for converting part dimensions in tooling dimensions, and verification-are discussed in detail. Implementation of the concepts is discussed with respect to automotive disc brake rotors. The features of the computer software developed to create the integrated system elements are also described.
