Chapter 7Conventional Numerical Control
Many of the achievements in computer-aided design and manufacturing have a common origin in numerical control (abbreviated NC). The conceptual framework established during the development of numerical control is still undergoing further refinement and enhancement in today’s CAD/CAM technology. It is appropriate that we devote a major part of this book to the subject of NC.
This chapter defines the basic concepts and applications of conventional numerical control. Modern NC systems rely heavily on computer technology. Chapter 8 deals with the topic of NC part programming, a procedure that depends greatly on computer-aided methods. Chapter 9 is concerned with computer control in NC systems. ...
