Title: Laser beam cutting method
Inventor: KANEOKA MASARU
IPC: B23K26/00
Filed: 1990-07-11
Abstract: PURPOSE:To obtain the same machining speed as at the time of machining continuously even if a laser beam is not emitted continuously and to perform laser beam machining with little streaks by regulating a duty ratio of an output pulse of the laser beam to a specific ratio and setting frequency of the output pulse above specific Hz. CONSTITUTION:The oxidation reaction temperature at a workpiece is raised and the extension region of the oxidation reaction temperature is reduced by regulating the duty ratio of the output pulse of the laser beam to <=70% (except zero) and setting the frequency of the output pulse above 1,000Hz. Accordingly, for instance, a pitch interval of a cut plane is made to <=0.18mm and roughness of the cut plane can be improved and the effect that the need for finish machining is eliminated is obtained. The effect of pulse cutting according to the invention can be also applied to metal and nonmetal in addition to aluminum, stainless steel, titanium, high carbon steel, etc., except mild steel material. In addition, in a pulse oscillator having the same pulse peak value and average value, the power of a power source and the strength of an electrode are increased and the frequency and duty ratio of this invention can be used.
