Integration of CAD and a cutting tool selection system

This paper describes a novel concept for the integration of a CAD system and a knowledge based system of the selection of cutting tools and conditions for turning operations (EXCATS). This integrated system (CADEXCATS) is capable of processing CAD data and automatically generating the component representation file for EXCATS using the IGES neutral format and a feature recognition approach. The workpiece representation model is capable to describe sophisticated turned components using Prolog facts and other operational linked keywords. In addition, CAPP related features are effectively incorporated into the CADEXCATS system. A set of rules is established for the automatic determination of set-up, detection of complex geometries, recognition of grooves and other important features. Illustrative examples are presented to test and validate the developed system.
