1. A three-dimensional laser beam machining apparatus comprising:

  • a robot having a plurality of robot axes;

    a YAG cutting tool mounted on said robot and having a laser head movable on an operating plane; and

    general control means for controlling the individual axes of said robot and said YAG cutting tool by software processing,wherein said general control means chronologically controls a two-dimensional position of said laser head based on a diagrammatic machining command for defining a path of movement of said laser head on said operating plane, and also chronologically controls a position of said robot in a direction perpendicular to said operating plane of said laser head in accordance with said two-dimensional position of said laser head and a three-dimensional configuration of a surface of a workpiece to be machined.
