ELECTRIC DISCHARGE MACHINING CONTROL METHOD AND ELECTRIC DISCHARGE MACHINING CONTROLLER

摘要

An electric discharge machining control method and an electric discharge machining controller capable of improving a machining speed by keeping an electrical discharge machining process in an optimum state even if an electric discharge machining area is small, wherein a difference signal from a target value and a machined-state detection value, a value obtained by adding a value obtained by multiplying the difference signal by a proportional gain and a value obtained by multiplying the difference signal by a first integral gain and integrating the multiplication result used as a first controlled variable, and a value obtained by multiplying a command value by a second integral gain used as a second controlled variable are determined, and a value obtained by adding the first controlled variable and the second controlled variable and multiplying the addition result by a machining trace vector used as the controlled variable of a drive for adjusting the distance between an electrode and a workpiece is used.
