Abstract

PURPOSE:To enable extremely fine and multidimensional control over the machining conditions by cheking up the adequacy of the state of machining gap at the beginning and ending stages of the period of stoppage of an interrupted high-frequency pulse. CONSTITUTION:Monostaple elements 19 and 20 oscillate an output pulse at the beginning and ending stages of the period of stoppage Toff of a monostaple element 18. The output pulse makes switching elements 6 and 7 continue, on one hand, and makes discriminating circuits 28 and 29 function on the other. When these discriminating circuits 28 and 29 receive operation instructing pulses from the monostaple elements 19 and 20, respectively, they check up the wave forms of voltage pulses generated in the therminals of resistances 9 and 10, respectively. When the state of machining gap is inadequate at both points of time, Toff is prolonged.
