PURPOSE:To vertically control a nozzle to surface of a work with hand control by obtaining two vectors from three points on the work surface and the vertical vector from vector product and making the posture of the nozzle to agree with this. CONSTITUTION:In a three dimensional laser beam machine, the nozzle 33 is vertically controlled to the work 34 with the hand control. Then, three points P1, P2, P3 on the work 34 surface are teached from an operation panel. From these three points P1, P2, P3 two vectors V1, V2 are obtd., and from the vector product of these vectors V1, V2, the vertical vector V to the work 34 surface is obtd. to match the posture of the nozzle 33 to the vertical vector V. By this method, the posture of the nozzle can be vertically controlled. |
