PURPOSE:To obtain a three-dimensional laser beam machine capable of grasping the teaching state of the whole at a glance by making up a pseudo working head corresponding to the direction of a nozzle of a working head to display the position of a teaching point and connecting the interval between the working heads through an interpolation locus. CONSTITUTION:When the working head is moved and stopped to push a teaching button, a teaching command discriminating means 27 outputs a signal to discriminate a interpolation command signal to a interpolation command discriminating means 28. At this time, when an interpolation button is pushed, the interpolation command discriminating means 28 reads the interpolation command signal to judge whether it is a linear interpolation or not. When it is judged to be a linear interpolation, it is informed to be a linear interpolation to the interpolation means 29. The interpolation means 29 interpolates the preceeding position and this new position linearly and informs a nozzle video making out means 25 of the result. The nozzle video making out means 25 makes two-dimensional transformation (axis (z) is transformed to axis (y)) of a locus drawn between the preceding position and this new position and a set nozzle direction vector and position, and a pseudo working head corresponding to the direction and position is displayed on a display part 2. |
