One of the most productive tools in the CNC world today is going largely unused! Indeed, most CNC users have never even heard of parametric programming, yet virtually all have excellent applications for it that will not only streamline their operations, but cut time, cost, and complexity from every machining cycle they run. Until now, parametric programming has been the best kept secret of CNC!

​

In Parametric Programming for CNC Machine Tools and Touch Probes, CNC expert and author Mike Lynch de-mystifies this simple yet sophisticated programming tool. In an easy-to-understand tutorial format, he presents a comprehensive how-to of parametric programming from a user's point of view. Focusing on the three most popular versions of parametric programming Å Fanuc's custom macro B, Okuma's user task, and Fadal's macro Å this book describes what parametric programming is, what it can do, and how it does it more efficiently than manual programming.

​

Part one of the book introduces you to the many features and benefits of parametric programming and how to apply them to improve the general utilization of your CNC machine tools. Part two shows you how to write parametric programs to drive your probing systems.

​

Including many real-world example programs and applications, this text shows how to identify applications for parametric programming and realize the dramatic gains it affords. For the CNC user wanting to stay at the cutting edge of manufacturing technology, this book is essential.
