Title:
ELECTRICAL DISCHARGE MACHINING METHOD AND DEVICE THEREOF
Document Type and Number:
Japanese Patent JP2001025921
Kind Code:
A
Abstract:
To minimize wear of an electro-tool at the time of electrical discharge machining.
This servo control means is provided with a regulator 62 for the internal voltage of a power source, a discharge generating device 63, a first element 64 disposed for computing a gradient Pn of an increase in discharging current, a second element 65 appropriate to compute the predetermined average gradient of the frequency of discharge, and a third element 61 appropriate to compute an arithmetic difference between a reference gradient Pref and the average gradient.
