Laser output control system

Abstract

A laser output control system responsive to a command signal from a CNC, which is capable of sharply reducing time required for transfer of waveform data from the CNC in executing laser-beam machining. An output control device, upon receiving the command signal from the CNC, reads registration data and a set of waveform data stored in advance in one of the registers and a memory of an output control circuit, respectively, and then multiplies a peak value of a specified set of waveform data by a waveform scale factor and an override value set in advance to a PMC to form the waveform data into a waveform having a desired peak value. Then, by the use of a frequency and the number of times of output of the registration data, a repetition period and the number of repetitions of the set of waveform data are determined. The output control device delivers an output waveform thus determined to a power supply for a laser oscillator.
