This is the third volume of three which will give the reader an insight into the current state of CNC technology with a focus on practical applications. This volume deals with CNC programming. It has been written in conjunction with a major European supplier of controllers in order to give the reader a more consistent and in-depth understanding of the logic used to program such machines. It explains how why and where to program specific features of a part and how to build them up into complete programs. Thus, the reader will learn about the main aspects of the logical structure and compilation of a program. Finally, there is a brief review of so me of the typical controllers currently available from both universal and proprietary builders. The author draws on his extensive experience as a practitioner and teacher. The text is thoroughly practical in character and generously illustrated with diagrams and photographs.
