摘要： A wire electrical discharge machining apparatus includes an NC control device, and the NC control device determines, during taper machining, whether the type of machining is a type (first type) in which an upper die is located on a workpiece side in comparison with a lower die or a type (second type) in which the upper die is located on the side opposite to the workpiece in comparison with the lower die on the basis of a machining program and corrects the positional relationship between the upper die and the lower die in accordance with the determined type of machining.

摘要： A wire electrical discharge machining apparatus capable of improving the shape precision of a continuous corner part includes a corner speed coefficient calculation device calculating a machining speed ratio between a middle corner section and a straight part from a machining volume ratio between the straight part and the middle corner section in which machining volume becomes a constant value. A corner speed coefficient interpolation device interpolates a speed coefficient calculated by the corner speed coefficient calculation device in a pre-corner section and a post-corner section. A speed reference calculation device calculates a machining speed reference based on a representative speed and the corner speed coefficient, and a drive control device controls a drive device. A continuous corner detection device determines whether continuous corner sections overlap each other when the length of the straight part connecting two corner parts is shorter than the length of the pre-corner section.
