Abstract
A power control method in a CNC (computerized numerical control) laser machining system including a CNC apparatus and a laser machining apparatus. The CNC apparatus (10) lowers a laser output by reducing both a pulse duty ratio and a pulse frequency in accordance with the lowering of a machining velocity when machining a corner portion. According to this method, a machining accuracy in the corner portion is improved, thermally influenced regions on the workpiece are reduced, and a surface roughness of the machined engraved surface is improved.
