WIRE ELECTRICAL DISCHARGE MACHINING DEVICE, WIRE ELECTRICAL DISCHARGE MACHINING METHOD, LEARNING DEVICE, AND INFERENCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/157308
Kind Code:
A1
Abstract:
A wire electrical discharge machining device according to the present invention comprises: a machining mechanism (13) for electrical discharge machining; a thickness estimating device (24) that estimates the thickness of a workpiece at a position where machining is being carried out during rough machining of the workpiece by electrical discharge machining; a thickness output device (25) that outputs, to outside of the wire electrical discharge machining device, thickness data in which position data is associated with thickness information indicating the estimated thickness; a thickness input device (26) into which thickness data is input from outside of the wire electrical discharge machining device; a step position estimating device (27) that estimates, on the basis of the inputted thickness data, the position of stepped sections where the thickness of the workpiece changes; an electrical condition control device (22) that controls application of a pulse voltage on the basis of the thickness data and the step information indicating the position of the stepped sections when finishing of a workpiece by electrical discharge machining is being carried out after the rough machining; and a control device that controls the machining mechanism on the basis of the thickness data and the step information when finishing is being carried out.
