Overview: Introduction to computer numerical control, fifth edition is the industry's most thorough, easy-to-follow, and well-illustrated introduction to the fundamentals of CNC technology and programming. Throughout, it relies on illustrations and interactive software to promote learning, not lengthy narratives. Coverage includes: programming linear profiles, programming with cutter diameter compensation, programming with subprograms, CNC lathe programming, and more. Program patterns are provided with many programs, quickly explaining what groups of programming blocks are intended to accomplish. This edition contains an all-new chapter on wire EDM technology and programming, as well as new and updated reference appendices.
