Title:
ELECTRO-DISCHARGE MACHINING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/161764
Kind Code:
A1
Abstract:
In order that an electric discharge state in an electro-discharge machining apparatus will be held constant, an electro-discharge machining control device (101) is provided with a machining power supply which applies a pulse-like voltage across a minute gap between an electrode and a workpiece being machined that are disposed apart at a predetermined distance in such a way as to face each other, thereby generating electric discharge; a state quantity detector (8) which detects an inter-electrode voltage across the minute gap between the electrode and the workpiece being machined; an electrode vibration state detection means (13) for detecting the amplitude of the inter-electrode voltage obtained by the state quantity detector (8); an adjustment factor setting means (14) for setting a factor by which to multiply an average inter-electrode voltage (9A) obtained by the state quantity detector (8) on the basis of the amplitude of the inter-electrode voltage (9B), which is obtained by the electrode vibration state detection means (13); and an assessment voltage setting means (15) for setting an assessment voltage (16) on the basis of the factor, which is output by the adjustment factor setting means (14).
