Abstract
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.
