Kind Code:
A1
Abstract:
The purpose of the present invention is to determine the position of generation of a shockwave in an assist gas (AG) freely ejected from a nozzle (2b) used for cutting a work using laser light. In an entire gap range (Ga) that can be set as a gap (G) which is a distance between a distal end of the nozzle (2b) and a surface of a work (W), an appropriate gap range (G1) that does not include at least the position of generation of a shockwave is set. The work (W) is cut with the gap (G) being set to a value within the appropriate gap range (G1).
