PURPOSE:To automatically and accurately carry out follow-up at high speed by calculating the deviation based on a reference signal from a reference dimension setting means and a detection signal from a machining dimension detection means by a deviation calculation means and controlling a driving means based on a deviation signal from deviation calculation means. CONSTITUTION:Width dimensions of an iron plate 2 slit-cut are detected by a vision sensor 5 and this detected value is compared with a preset reference value. The deviation is calculated and it is discriminated whether or not the deviation is within a tolerance and when it is expected to deviate from the allowance, a motor 4 to move a laser beam machining head 3 is controlled based on the deviation and the laser beam machining head 3 is corrected and moved as the quantity of correction by the deviation amount. By this method, the quality of a product can be improved. |
