Part of the Fundamental Manufacturing Processes (FMP) video series, this program explains the basics of Computer Numerical Control, or CNC by featuring segments on: Computer Numerical Control Principles and Computer Numerical Control Programming. The CNC Principles section 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 section 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, and computer-aided manufacturing.
