The method comprises establishment of a short-circuiting time, establishment of an arc time, and controlling the energy supplied to the electrode. The energy supply is controlled in such a way that the energy supply is increased if a measured short-circuiting time of a total period time, where the period time is the sum of the short-circuiting time and the arc time, exceeds a defined adjustable set value and decreases if said short-circuiting percentage goes below said set value.

A wire electrical discharge machine includes: a gap voltage detector for detecting a voltage across an electrode gap; a first voltage control unit for applying a first voltage to the electrode gap; a discharge determiner for determining whether or not the electrode gap is in a discharging state during application of the first voltage; and a second voltage control unit for supplying a machining current through the electrode gap when the electrode gap is in a discharging state. After a supply of the machining current to the electrode gap, even when a discharge is induced by the next application of the first voltage to the electrode gap, the second voltage control unit prohibits application of a second voltage to the electrode gap.

To automatically change and set machining conditions suitable for a plate thickness even when machining paths of a rough machining step and an end surface finishing step are different in level difference machining in which the plate thickness changes during machining. In a wire electric discharge machining method and a wire electric discharge machining apparatus of the disclosure, an XY-plane of a workpiece stand is divided into small regions to form a plurality of divided regions, and a plate thickness of the workpiece is detected and stored in association with the divided regions. Thereafter, whether there is a level difference ahead of a traveling direction of a machining path is estimated according to plate thickness information associated with the divided regions and a plate thickness of the workpiece at a current machining position, and machining conditions are changed.

A workholder with a sleeve carried by a body and providing at least in part a circumferentially continuous fluid chamber between them and at least two circumferentially spaced apart locators carried by the body axially over the sleeve and projecting radially of the sleeve. A pressurized fluid in the chamber can change the diameter of the sleeve to move the locators generally radially relative to the body into firm engagement with a workpiece so that it is carried by the workholder. The locators may be received in part in a collar received at least in part axially over the sleeve with a portion of each locator projecting radially of the collar.
