Computer Numerical Control

Part of SME's Fundamental Manufacturing Processes Video Series, this program explains the basics of computer numerical control (CNC) by featuring segments on CNC principles and CNC programming. The CNC principles segment highlights the rectangular coordinate system and its use in generating precision tool paths. Integral elements of the rectangular coordinate system are presented, including: program zero, coordinate points, coordinate polarity, the absolute mode, the incremental mode, quadrants, and the various axes of motion. The CNC programming segment features the step-by-step examination of CNC part program commands and their various letter addresses and numeric values. Also presented are discussions of point-to-point positioning, contouring, interpolation, compensations, special programming features, manual programming, computer-aided part design, or CAD, and computer-aided manufacturing, or CAM.
