<p><P>PROBLEM TO BE SOLVED: To facilitate the teaching of a posture by automating the vertical regulation of a nozzle in a laser beam machine of five-axis control. <P>SOLUTION: An index (n) is initialized (S1), the nozzle is made to take initial posture (S2), and in the case the detected value by a photo detector 30 lies within an allowable range, it is determined that the vertical regulation is completed (S3, 12). In the case other than that, the nozzle is tilted to the designated angle/direction of the n-th by fixing control for a front point (S4), and, as a C axis is rotated by 360 degrees by fixing control for the front point, the transition in the intensity of reflected light is recorded (S5). In the case the maximum value lies within an allowable range, it is determined that the vertical regulation is completed (S6, 12). In the case other than that, while the A axis value is changed to±both directions within a prescribed angle range by fixing control for the front point from the tilted state where the maximum value has been obtained, the transition in the intensity of reflective light is recorded (S8). In the case the maximum value lies within the allowable range, it is determined that the vertical regulation is completed (S9, 12). Thereafter, the treatment is repeated in the range not exceeding a limiting number N (S10, 11). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
