Abstract

PURPOSE:To obtain a hole of high quality by moving an end effector along a curve having a prescribed shape connected smoothly to the closed figure and then, performing drilling on a work. CONSTITUTION:The respective teaching data on the central point P and the radius R are read out from a memory. The position of a point Q separated by distance R in the prescribed direction from the central point P is obtained by operation and the position and shape of a semicircle S with the two points P and Q as both end points are specified. When the semicircle S is specified, a laser beam torch is positioned toward the central point P and then, moved from the central point P to the shifting point Q along the semicircle S. The work is cut, namely, the hole H is cut off along a circle C by moving the torch by 360 deg. along the semicircle S while irradiating the work with laser beam. By this method, the cut surface of the cut-off hole H is smoothed without changing suddenly the mobile direction of the torch and generating vibration.
