Next, the operation of the above device will be described. In order to focus the laser beam 1 and irradiate the insulating material 5 to be cut, and to cut with a good-quality cut surface, an appropriate laser output corresponding to the cutting speed is required. Figure 6 shows 6.4
This is a quality evaluation of the cut surface viewed from the relationship between the cutting speed and the laser output of a press board (insulator to be cut) having a thickness of mm. In the figure, area A: Due to lack of laser beam energy
An area where an uncut part remains at the bottom of the press board due to (laser output shortage) or excessive laser processing speed. Region B: The press board is completely cut, but there is a portion where the flow of assist gas is insufficient at the lower part of the cutting groove, and as a result, some carbide is generated. Region C: A region where high-quality cutting is possible without the formation of carbide on the cut surface. Region D: A region where a small amount of carbide is generated due to a thermal oxidation reaction at the upper part of the cut surface due to the influence of the visual field of the focused distribution of the laser beam because the processing speed of the pressboard is too slow. Region E: A region where the carbides can be clearly discriminated by the naked eye because the thermal oxidation reaction time is long and the temperature is high when the pressboard processing speed is further reduced. As described above, depending on the combination conditions of the output of the CO 2 laser and the cutting speed depending on the thickness of the press board, there is a good region where carbide is not generated on the cut surface. Therefore, the cutting speed of the insulating material 5 to be cut by the laser beam 1 is detected, and the output of the laser oscillated from the resonator 7 is variably controlled to the optimum output by the power control from the power board 11 corresponding to this cutting speed. Thereby, it becomes possible to cut an insulator having a good cut surface.
