Abstract

Method for correcting the control program of an automatic glass cutting machine including the steps of adding in counters signal pulses representative of travel of a scanning head in X and Y directions, checking the counter totals at the starting and end points of travel of the scanning head and introducing pulses in the program to bring the counter totals to a zero value. A device for correcting the control program of an automatic glass cutting machine having counters for adding signal pulses representative of travel of a scanning head in X and Y directions and a pulse generator for each counter which may put a required number of pulses into memory to bring the total count in the counters to zero at the completion of travel of the scanning head.
