Abstract
A three-dimensional laser beam machining apparatus using a YAG cutting tool. A robot controller functioning as a YAG cutting tool controller is connected to a laser beam supply through a optical fiber and to a robot having an arm end on which the YAG cutting tool is mounted. When a diagrammatic machining command for the YAG cutting tool is given, an first internal program for the diagrammatic machining command and a second internal program for compensating a robot position in a z-axis direction are created. These internal programs are executed in parallel by a multi-task function. The YAG cutting tool is two-dimensionally controlled so as to depict a diagram, such as a rectangle and a circle. When the YAG cutting tool moves across the axis of a cylindrical workpiece, the robot position in the z axis direction is compensated so that the gap between the laser head and an cylindrical surface of the workpiece is kept constant.
