Abstract

The electrode, a tool which is used for wire electrical discharge machining (WEDM), is a tiny flexible metal wire, therefore, in WEDM machining process, its form and position will inevitably vary because of the action of many forces, and these dynamic variations have a direct influence on machining precision and stability, especially in the high-speed WEDM (WEDM-HS) machine process; the variations of form and position have been a critical obstacle to improving machining quality and implementing multi-cut processing. In this paper, the variation regularity of wire-electrode has been investigated by experimental analysis, and some corresponding measures have been suggested to stabilize the form and position of the wire electrode in the WEDM-HS machining process.
