Full credit should ASME MEMBEiiiS be given to ASME, the Technical Division, and the author (s). An analysis is presented of computerized numerical control (CNC) for manufacturing systems. Two types of CNC systems referred to a$ Reference-Pulse and Sampled-Data are· discussed. In the first system, reference pulses are generated by the computer and supplied to an external digital control loop. With the Sampled-Data technique, the computer serves as a comparator of the control loop and transmits the position error at fixed time intervals. The basis for selection of the particular type of CNC system and the required system parameters are given.
