ABSTRACT:
A sinker electric discharge machine jump control device for reciprocating a tool electrode along a Z-axis with respect to a workpiece using a servo motor in order to expel contaminated fluid from a work gap. The jump control device includes a commanded current generator, the current generator generating a commanded current for the servo motor, and a commanded velocity generator, the velocity generator dividing a locus of a jump stroke into a plurality of segments and generating a commanded velocity for each of the plurality of segments. Additionally, the jump control device includes a velocity override calculator, the calculator generating a velocity override according to the commanded current, and a commanded velocity modifying device, the modifying device modifying the commanded velocity according to the velocity override during the jump stroke.
