Precisions of Wire-EDM are spoiled by a wire deflection and a wire vibration during the machining.
In the previous report, we described about the simulating procedure of Wire-EDM, treating from voltage supply to discharge, explosion, machining, wire movement and their repetition. Also we showed experimentally obtained characteristics of ignition delay times and gap lengths, which is necessary for the simulation. Next we showed few analyzed results and described that the viscosity in cut groove should be greater than that in open space.
In this report we investigate the propriety of the simulation model analyzing straight rough cuttings, and describe the influence of electrostatic force and EDM conditions on cutting accuracies.
