Abstract
This paper shows how production engineering practice can be built into the software routines of CADCAM systems to aid the integration of design and manufacture. The paper describes aspects of a software package which has good production engineering practice built into it so that the good practice is standardized. The package has been developed to carry out the process planning of turned parts using as a starting point the component geometry entered into the CADCAM system. The package automatically plans the part for specified manufacturing facilities. The use of the package is thought to have considerable economic benefits.
