Abstract
A machining control device for discharge machining equipment. The arrangement provides discharge machining equipment such that it may accomplish discharge machining on a workpiece under appropriate machining conditions suited to the progress of machining. Effective and stable discharge machining can be effected by structuring machining conditions, which are converted to control set values for the machining control device, into such a fashion as to continuously shift from a rough machining mode to a precision machining mode as an electrode travels.
