Teaching manner null of job position teaching

摘要

PURPOSE:To set a work position beyond the work area of a work machine by fixing a dummy work which has the same work position as the work machine and obtaining the fixed position of the dummy work and the work position on the dummy work. CONSTITUTION:The x-coordinate and y-coordinate of a positioning pin 29 are transmitted to pulse encoders 17 and 24 by wires 15 and 23 and are converted into electric signals. The teaching of the work area is that a length is set to correspond to a pulse by a calibration jig having a specified length, the dummy work 32 is fixed on a base plate 8, and the coordinate of a reference point on the dummy work is obtained so as to store it in a storage device (not illustrated). Next, the positioning pin 29 is shifted to the objective work position and the coordinate is stored. For setting the approaching direction of the positioning pin 29, a rotary head 28 is rotated, and a value corresponding to the angle of rotation is stored.
