ABSTRACT:
A laser machining system with x, y and z-axis beam manipulating mechanisms to perform welding, cutting and localized heat treating operations on a workpiece with the operation of the system for each operation and the changeover between operations being under the control of an automatic control system. A computer numerical control (CNC) system provides control of the laser functions and movement of the laser beam using a sampled-data following error servo system.
