ABSTRACT:
A discharge-servo curve control method and device for an electrical discharge machine enables multiple discharge-servo curves to be chosen during a machining process in real-time. The control device includes a storage unit, a setting unit, a reading unit, a program unit and an instruction-judging unit capable of swapping control during execution of the program whenever a discharge-servo curve instruction is encountered.
