摘要： A wire electrical discharge machine includes: a determination unit that determines whether or not a first route and a second route, each including an approach path, a machining path and an escape path in this order, are set in this order as a movement route of a wire electrode; and a wire movement control unit that, when the first route and the second route are determined to be set in a machining program in this order as the movement route of the wire electrode, causes the wire electrode to transition from the machining path of the first route to the machining path of the second route without moving the wire electrode along the escape path of the first route and the approach path of the second route.

摘要： A wire electrical discharge machine includes: a mounting table having a placement plane on which a workpiece can be placed; a first guide portion and a second guide portion for stretching a wire electrode therebetween. The first guide portion is integrally equipped with a probe. The relative position in the placement plane between the probe detecting its abutment with the workpiece and the first guide portion before moving the relative position between the first guide portion and the second guide portion is stored as an offset. This offset is corrected based on the tilt information indicating the tilt state of the workpiece relative to the placement plane. Thus, it is possible to obtain the corrected offset in accordance with the tilt state of the workpiece after changing the relative position between the first guide portion and the second guide portion.

摘要： To provide a wire electrical discharge machine for which the machining precision of corner parts and corner exit parts in a workpiece are improved. A wire electrical discharge machine includes a machining path compensation unit which compensates a machining path, in a case of creating a corner part which is a circular arc as a second machining block, by compensating a position of a center of the circular arc of the second machining block by way of a first compensation vector calculated based on at least one indicator among the four indicators of deflection of a wire electrode, etc., and inserting a linear first compensation block between an end point of the first machining block and a start point of a second machining block which was compensated, and by eliminating a predetermined distance from the start point of a third machining block, creates a starting point of this third machining block, and then inserts a second compensation block between the end point of the compensated second machining block and the created starting point of the first machining block.
