ABSTRACT:
A three-dimensional laser coordinate transformation system for a three-dimensional laser machining apparatus includes a preprocessing calculation unit (4) decodes a machining program stored in a memory (2) and outputs a command value for each axis. Coordinate transformation unit (8, 9) transform the command value into a command value on the coordinate system of an actual workpiece by a coordinate transformation matrix, and the transformed coordinate command value is interpolated by an interpolation means (11) to output an interpolation pulse. Servo motors (21, 22, 23, 24, 25) are driven in response to the interpolation pulse to thereby machine the workpiece.
