ABSTRACT:
An output waveform control device generates a pulse wave by processing waveform data from a CNC (Computer Numerical Control) unit and delivers the pulse wave for pulsed oscillation of a laser beam. The waveform data transferred from the CNC (Computer Numerical Control) unit is input to a duration-allocating device provided within a laser oscillator. The duration-allocating device of the laser oscillator allocates a duration .DELTA.T, set to a desired value, to each step of the waveform data W. The durations .DELTA.T are allocated in a shorter-to-longer order, and the resulting waveform data is transferred to a pulse wave-generating device. The pulse wave-generating device generates a pulse wave P1 based on the received waveform data W. The pulse wave P1 thus generated is preferably includes 20 pulse segments, each of which has a duration .DELTA.T allocated thereto which can vary from one segment to another. Accordingly, each pulse segment of the pulse wave P1 has a duration set as desired, and the pulse wave duration .SIGMA..DELTA.T as a total of the durations .DELTA.T, can be set as desired. This makes it possible to carry out laser beam machining in a suitable manner dependent on the type of machining.
