CNC Turning Center Operations and Prove Out. Computer Numerical Control Operator/Programmer. 444-334.
Skowronski, Steven D.
This student guide provides materials for a course designed to instruct the student in the recommended procedures used when setting up tooling and verifying part programs for a two-axis computer numerical control (CNC) turning center. The course consists of seven units. Unit 1 discusses course content and reviews and demonstrates set-up procedures for various tool length compensation methods. Unit 2 instructs the student in methods of recovering from emergency stop or feed hold conditions, the trial run of a part, and methods of adjusting machined dimensions using program editing and offset register adjustments. Unit 3 lists almost all the errors that the student may encounter. In units 4-7, the student performs a set-up and program verification of the following: (1) a CNC program using point to point and linear interpolation programming methods; (2) two more CNC programs while being introduced to the concepts of tool nose radius compensation; (3) a CNC program using circular interpolation methods; and (4) a CNC program using metric units of millimeters for positional data. Contents of each unit include an introduction, list of objectives, contents, and materials for three sections. These sections contain narrative instructional materials, an assignment section that requires written answers, a project section with instructions and necessary data sheets, and competency check list.
