Electrical Discharge Machining (EDM).
Abstract
The objectives of this program were to increase the efficiency of the electrical discharge machining process, decrease manufacturing costs, increase reliability and structural integrity of production parts, and extend the utilization of EDM manufacturing processes. Optimization of the EDM parameters in order to obtain the maximum efficiency was accomplished by a study of the parameters using multivariable regression analyses. This study has shown the quantitative effects of the independent variables and certain interactions on the machining results. The conditions for obtaining maximum metal removal rates consistent with specified surface integrity were established for eight materials. It was determined that the on-time influences the surface integrity more than the peak current. The recognition of this has permitted increasing metal removal rates by using higher peak currents in finishing operations and maintaining low on-times to limit surface degradation. As a result the efficiency of the EDM process is increased and the costs can be decreased.
