摘要： A wire electrical discharge machine includes: a drive control unit for moving a wire electrode relative to a workpiece along a machining path; a path determination unit for determining whether or not the machining path includes a linear path section that crosses a boundary line between a thick portion and a thin portion of the workpiece; and a path compensator for compensating the machining path so as to form, in the thin portion, a protrusion projecting outward from the boundary line when the path determination unit determines that the linear path section is included.

摘要： Provided is a device for controlling a wire electrical discharge machining apparatus, the device making it possible to improve machining precision even in machining in which a plurality of corner control segments overlap. A device for controlling a wire electrical discharge machining apparatus, the device comprising: a storage unit that stores a machining program and a prescribed plurality of corner control patterns that can be applied to each corner part; a control unit that performs corner control for switching between prescribed machining conditions on the basis of a corner shape during machining of a corner part; a calculation unit that calculates a corner control segment from the start point and the end point of the corner control; and a selection unit that, when the corner control segments calculated by the calculation unit overlap, selects one corner control pattern to perform in a prioritized manner from the storage unit.
