Written in simple, easy-to-understand language by a skilled programmer with many years of experience teaching CNC machining to industry and in the classroom, this book provides thorough descriptions of many operation and programming functions and illustrates their practical applications through examples. It includes in-depth information on how to program turning and milling machines that is applicable to almost all control systems and presents detailed coverage of subjects not addressed by the majority of existing texts. Hundreds of drawings, screen shots, and photos are used to improve clarity. It keeps all theoretical explanations to a minimum so as to not detract from a full understanding of practical programming skills and strategies. With its wide range of data about the selection of tools, cutting speeds, and the technology of machining, this book would be a handy on-the-job reference for engineers, programmers, supervisors, and machine operators, besides serving as a proven and effective textbook for anyone learning CNC programming for the first time. It contains expanded sections on CAD/CAM and Conversational Programming that offer insight into the modern methods of CNC programming. It includes a modern CNC controller representation in the Operation Section. It thoroughly describes mathematical formula usage necessary for creating programs manually. It provides many practical examples and study questions throughout, allowing users to demonstrate their proficiency. It offers a glossary of terminology and useful technical data and charts needed for effective programming. It illustrates how to create each programming example through clear step-by-step presentations.
