Abstract
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.
