Research on technology of wire electrical discharge machining with a rotator wire electrode

The wire electrical discharge machining with a rotary wire electrode is a new technology of WEDM, which can realize high machining quality as WEDM-LS and low price and operation cost as WEDM-HS. The machining mechanism of WEDM with a rotary wire electrode is researched in this paper. The main reasons of improving machining quality by WEDM with a rotary wire electrode are that on the one hand an inertia force effect of high speed rotation makes the stiffness of the wire stronger and the stability of the wire in space better and the vibration of the wire less, on the other hand the wire electrode of high-speed rotation has the effects of both cutting and grinding.
