Abstract
In this study, the explosive load acting on a wire surface generated by discharges at the rough cut and the finish cut of wire EDM is investigated. The hydrodynamic explosion process in the water-filled gap from each discharge is numerically analyzed using the adiabatic bubble expansion model, and the impulsive load acting on the wire surface is calculated. The distribution formula of the discharge number on the wire surface is derived and the total load acting on the wire generated by continuous discharges is estimated. The analyzed results are compared with the experimental results and also with those derived from the simple model, assuming that the impulsive load of each discharge is constant and acts normally on the wire surface. Results show that the influence of the skimmed depth on the wire deflection at the finish cut is explained by the numerically analyz.ed results but not by those of the simple modeL
