ABSTRACT:
A laser machining apparatus capable of changing a laser output condition at a desired machining position and time without regard to interpolation period (ITP). When the remaining motion command amount in the former of successive blocks, used for the interpolation period Q0between these blocks, is less than a motion command amount corresponding to a command speed in the ITP, such deficiency is supplemented by a motion command for the latter block, thus maintaining a moving speed unchanged. The laser output condition is changed between the blocks. In an ITP Q−1, a CNC sets the time period and the laser output condition in laser output control signal generating unit which changes the laser output condition when the time period has elapsed from the start of the ITP Q0, making it possible to change the laser output condition at an arbitrary time without being limited by the ITP.
