Provided are a wire electric discharge machine, a correction device, and a correction method which accurately correct position information indicating the position of a supporting point of each of an upper guide and a lower guide. The correction device includes: a storage unit that stores the position information; an inclination control unit that causes a wire electrode to incline at a predetermined angle; a measurement unit that measures a relative movement amount from a state in which the lower guide and a measurement site are separated by a predetermined distance in a relative movement direction to a state in which the wire electrode inclined at the predetermined angle reaches the measurement site; and an information correction unit that corrects the position information of the storage unit on the basis of the predetermined angle and the relative movement amount.

Wire electric discharge machine, correction device, and correction method

A machine learning device provided in a controller for controlling a wire electrical discharge machine uses state variables (including data relating to a correction amount, a machining path, machining conditions, and a machining environment) observed by a state observation unit and determination data acquired by a determination data acquisition unit to machine-learn a correction for a machining path. Using the learning result, the machining path can be corrected automatically and accurately on the basis of a partial machining path, the machining conditions and the machining environment of the machining performed by the wire electrical discharge machine.

Controller and machine learning device

A wire electrical discharge machine for performing electrical discharge machining on a workpiece by applying voltage across an electrode gap between a wire electrode stretched between an upper nozzle and a lower nozzle and the workpiece to generate electrical discharges, includes a lifting mechanism configured to move the workpiece in the travelling direction of the wire electrode.
