Abstract
In carrying out precision laser-beam machining by using a laser-beam machining head driven by an additional motion-axis means 8 of a laser robot unit 1, a CPU accommodated in a robot controller 10 calculates time A+B necessary for a laser beam projecting nozzle to travel a distance between a position corresponding to a position of origin OR of a machining locus and a position corresponding to a starting point E on the machining locus at a quick-feed speed, and time C necessary for the laser beam projecting nozzle to travel the same distance in a laser-beam machining mode not including quick-feed operation, compares the times A+B and C, and provides feed motors MA and MB accommodated in the additional motion-axis means 8 with an automatic quick-feed command, when the time A+B is shorter than the time C to thereby enhance an efficiency of the laser machining operation.
