Abstract
A method of automatically measuring the flexure value of a wire electrode 1 in a wire-cut electric discharge machine is disclosed. At a measurement point in the course of electric discharge machining, the electric discharge is temporarily stopped, and whether or not the wire electrode 1 and a workpiece 2 come into contact is sensed by a contact sensing device 107a. The wire electrode 1 and the workpiece 2 are moved relatively to advance or retreat in accordance with the sensed touch signal TS, and the distance .epsilon..sub.1 of movement until the contact state changes, is measured. The flexure value .epsilon. is obtained calculatively from the measured movement distance .epsilon..sub.1.
