Dynamic Characteristics Analysis and Simulations of Transverse Vibration of Axially Moving Electrode Wire in WEDM
Many factors influence WEDM (Wire-cut Electrical Discharge Machining) processing precision, and the influence of various factors on the processing 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 wire vibration are analyzed and simulated. This study provides a relevant theoretical basis for optimizing processing parameters, reducing the wire vibration and improving machining precision.
