Abstract
A laser machining control method using a numerical control system for controlling an X-Y table. A command program (2) in a memory is read out for each one block to cause a lamp on an operation panel (5) to be lit. An operator changes, sets and inputs an output power (S), a frequency (P) and a pulse duty (Q) depending on required conditions. The input conditions are applied to a high-frequency power source (6), and laser machining is carried out under these conditions.
Claims1
A laser oscillator control method for changing a command program and executing laser machining by controlling an X-Y table with a numerical control system, said method comprising the steps of:
- (a) reading out a block of command program, from a copy of the program being used for laser machining, stored in a memory and transferring the block of the command program to a preprocessing arithmetic unit;
- (b) converting the block of the command program into executable form, laser machining being carried out during converting of the block of the command program into executable form;
- (c) lighting a lamp for alerting an operator each time one block of the command program is converted;
- (d) changing laser machining conditions of the converted block of the command program by a keyboard or a switch on an operation panel;
- (e) depressing an executing button on the operation panel;
- and
- (f) executing laser machining with the changed block of machining conditions by distributing a pulse to the X-Y table while simultaneously performing laser machining.
