A method and system for control of the technological advance for sparks processing machines

摘要

According to the method, the speed of advance is modified so as to keep the voltage level between the electrodes within a given range at the moment of each discharge. A logic device (SL), which includes three comparators, determines the voltage reached and causes the speed of advance to be increased, maintained or decreased, depending on this voltage. In this manner, the working gap between electrodes remains relatively constant throughout the entire machining operation, independently of the speed. IMAGE
