Some Issues Regarding Finite Element Modelling of Micro-Electrical Discharge Machining Aided by Ultrasonics

Abstract:

The paper deals with finite element modelling (FEM) of the process of micro-electrical discharge machining of micro-holes aided by ultrasonic longitudinal oscillations of workpiece (μEDM+US). FEM of the process comprises two components: the thermal one due to μEDM removal mechanism, and the ultrasonic one caused by cavitation effect generated inside the lateral working gap. The FEM results obtained are validated by experimental data in terms of craters dimensions produced by single discharges, leading to optimization strategy of process parameters.
