Query: Terrific user-friendly textbook

Extreme care and painstaking detail went into this user-friendly primer on Mastercam. I feel it is a great way to introduce machinists and CNC operators to Mastercam 9 and virtually minimize the traditional learning curve. It is also good for advanced programmers who need to brush up on some of the basics. I myself needed to master some specific processes such as creating operations and tool libraries, which isn't explained well in the help menu or other Mastercam texts. I found it was explained in this book in a thorough manner with graphic details of each step. I would recommend it to CNC tech students, machinists and operators who would appreciate something written from a machinist's point of view.
