Abstract

The present invention is related to a method for determining a condition of a wire electrode deployed in a fastwire cutting machine. The fastwire cutting machine comprises a wire traveling circuit in which the wire travels back and forth, with a first- and a second wire guiding head by which the wire electrode is guided and positioned in relation to a workpiece laying between these wire guiding heads. The wire electrode is in contact with a first- and a second electrical contact, both contacts being located on the wire traveling circuit,and that a value reflecting an electrical impedance Z_L of the wire electrode segment L between the first electrical contact and the second electrical contact is measured. The measurement of said wire electrode segment L is conducted in a dry state, and that the condition of the wire electrode is derived from the measured value reflecting the electrical impedance Z_L of said wire electrode segment L.
