Working method using laser light

Abstract

Abstract PURPOSE:To improve the accuracy of cutting sizes and to reduce a working time by performing both scribing and cutting continuously by changing the output of laser light. CONSTITUTION:First a scribing line is drawn on the surface of the work 21. For example, gaseous Ar 19 is selected with a valve stand 17 by the signal from a control device 23, and is ejected from a nozzle 15. The scribing line is beforehand programmed in an NC unit 22, and the on-off of laser light 12 and the high speed movement of an X-Y table are accomplished by the signal from the unit 22. Upon completion of the scribing work, the auxiliary gas is changed over to gaseous O2 18 for cutting from the inert gas for scribing by a solenoid valve in the stand 17 according to the signal from the unit 22. The laser output is also increased to the output at which cutting is possible by increasing the discharge current of a laser oscillator 11 in accordance with the signal from the unit 22.
