Product and Process Design,nd a research project was therefore undertaken to study this possibility. What emerged from the effort was software that proved to be of value to industry and for teaching of manufacturing engineering in universities. The concepts underlying this software are outlined here and we commence by looking at the nature of product and process design.

Tutorial on Part Planning, developed through teaching. The software and to how to install it can be downloaded from the website .. There are a number of steps involved in part planning and they are outlined in Fig. 5.1. To experience them in detail we go through a simple exercise involving the manufacture of a pencil sharpener shown in Fig. 5.2
