Many factors influence WEDM(Wire-cut Electrical Discharge Machining) machining precision, and the influence of various factors on the machining precision are expressed by wire electrode dynamic form ultimately. In this paper, the transverse vibration theoretical model of the axially moving electrode wire coupled with thermal stresses is established by the principle of Hamilton. The influence of various processing parameters on machining precision are analyzed and simulated. This study provides a relevant theoretical basis for optimizing processing parameters, reducing the wire vibration and improving machining precision of workpiece.
