<p>A system which controls the jump of an electric spark machine. The discharge condition is estimated from the discharge voltages (Vn, Vm, Tn) across an electrode (34) and a workpiece (35) and from the discharge current (In). The estimated discharge condition is inputted to a fuzzy control unit (12), which makes fuzzy reasoning about the estimated discharge condition in order to determine the increment (δT) of the jump period and the increment (δD) of the jump distance. Jump period distance changing means (23) determines the jump period (T) and jump distance (D), and jump control means (24) makes jump control on the basis of these values so as to conduct discharge machining. The improvement in the machining speed and condition of electric spark machining can be accomplished thereby.</p> |
