LASER MACHINING METHOD AND LASER ROBOT FOR EXECUTINGF THIS METHOD

摘要

In a method for effecting precision laser machining to a work by a laser machining head through additional operation shaft means (8) mounted to a robot body (1) of a multi-joint type laser robot, a required time (A+B) for taking the machining head by rapid feed from an origin point (OR) to a machining start point (E) according to various machining specifications stored in a rewritable storage means and a required time (C) for taking it similarly to the starting point without using rapid feed are calculated and compared with each other by arithmetic means (CPU) provided to a robot controller (10) of the laser robot. Only when the required time (A+B) is shorter than the required time (C), a rapid feed command is given automatically to driving motors (MA, MB) of the additional operation shaft means (8) so that the rapid feed operation of the laser machining head becomes effective to a predetermined laser machining trajectory. In this way, judgement is made automatically and laser machining efficiency can be improved.
