ABSTRACT:
A method of and an apparatus for automatically setting or resetting a machining-electrode wire on an operating set-up on a traveling-wire electroerosion machine wherein a broken free end portion of the electrode wire is vibrated with a small amplitude while being advanced along a straight line path for the electrode wire defined between a pair of guide members and with which a preformed starting through-hole in the workpiece is located in alignment. This allows a smooth and non-encumbered threading of the flexible electrode wire which has little self-supporting ability through the starting through-hole.
