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： It is a purpose of the present invention to provide a wire electrical discharge machining system allowing a wire electrical discharge machining device and a robot to operate in conjunction with each other with high efficiency. A wire electrical discharge machining system 1 includes wire electrical discharge machining devices 7, 11, and 15, and a robot unit 17 that mounts a workpiece on the wire electrical discharge machining device. The wire electrical discharge machining devices 7, 11, and 15 may each perform either rough machining with supported cores or finishing machining after the cores are removed. Subsequently, core processing may be performed by means of a corresponding dedicated apparatus. Also, the core processing may be performed by means of a single common apparatus. The robot unit 17 mounts and collects the workpiece so as to allow these wire electrical discharge machining apparatuses to effectively operate, thereby providing wire electrical discharge machining with improved efficiency for the overall system.

摘要： A wire electrical discharge machine machines a workpiece so as to have different machined shapes on a top surface and a bottom surface of the workpiece. The wire electrical discharge machine includes: a distance measuring sensor for moving within a machining area of the wire electrical discharge machine and measuring a distance between the distance measuring sensor and an object to be measured; and a vertical position calculating unit for calculating a distance between a reference surface and the top surface and a distance between the reference surface and the bottom surface, from a distance between the reference surface and the distance measuring sensor, a distance between the top surface and the distance measuring sensor, and a distance between the bottom surface and the distance measuring sensor, measured by the distance measuring sensor.

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.

摘要： A wire electrode is hung from an upper die guide of a wire electric discharge machine toward a workpiece, a distance from a position where the wire electrode on the top surface of the workpiece is hung down to a top end position of a machined groove formed by the electric discharge machining is calculated based on a commanded taper angle and the distance from the top surface of the workpiece to an upper die guide fulcrum position of the upper die guide, and automatic wire connection is performed by moving an upper nozzle by the calculated distance. In this way, a wire connecting operation can be performed in the vicinity of the tapered groove.

摘要： A machining path creating device for wire electric discharge machines creates a machining path for machining a keyway in a side surface of a round hole. The machining path creating unit compares a “keyway depth” and a diameter of the round hole input by an operator. The machining path creating device determines that the input “keyway depth” is a cut depth when the input “keyway depth” is smaller than the diameter of the round hole and that a value obtained by subtracting the diameter of the round hole from the input “keyway depth” is the cut depth when the input “keyway depth” is larger than the diameter of the round hole.
