Abstract

The effect of the tool electrode wear on the accuracy is very important problem in the Rotating Electrical Discharge Machining (REDM). Two mathematical models of REDM are presented: the first one considers machining with the face of the end tool electrode and the second one considers EDM with the lateral side of the electrode. The software for computer simulation of EDM machining with the side and face of the electrodes has been developed. This simulation model for NC contouring EDM using rotating electrode may also be applied for tool electrode path optimization. The experimental results confirm the validity of the proposed mathematical models and the simulation software.
