ABSTRACT:
An electroerosive wire-cutting method and apparatus in which the traveling wire electrode is heated in its position-setting step prior to a desired machining operation so as to establish for the operative section of the wire electrode thermal conditions the same as those to be experienced during the machining operation. Such heating may be effected, for example, by passing a heating current through that section of the wire electrode from an independent heating current source via wire guides.
