PURPOSE:To make possible the cut processing, where finishing is unnecessary, for the material to be processed which is being bent into an arc, by providing the automatic control mechanism, which can adjust the cut speed of the laser beam for the material to be processed into a fixed value, in the laser processing device equipped with the numerical control device and so on. CONSTITUTION:In the known laser processing device consisting of the mechanical system, which supports the laser beam oscillator rotatably and can incline the oscillator for the rotation axis properly, and the mechanical system equipped with the numerical control device, which causes the laser beam to run on the material to be processed automatically according to commands, at the processing point of the material to be processed, automatic control mechanism 100 which adjusts the relative speed between the material to be processed and the laser beam to move the laser beam for the material to be processed in the processing direction in a constant speed and can perform cut procession for longitudinal-direction cut procession of the part of the material to be processed which is being bent into an arc is arranged in the known numerical control mechanism (the numerical control mechanism consisting of cut processing instruction tape 62, tape reader 64, operation brain part 66, and so on), thus constituting the device. |
