Die-Sinking by Electroerosion-Dissolution Machining

The electroerosion-dissolution machining (EEDM) is a combination of pulsating electroerosion action aided by electrochemical dissolution. In the present study, the process is sustained for shaping small shallow dies. The kinematics of EEDM leading to the elevated rates of metal removal as well as satisfactory surface integrity and dimensional quality are identified. The machining parameters such as the specific metal removal rate, power utilization factor and die-shaping factor are evaluated experimentally and by empirical relation. The process characteristics are contrasted with electrochemical machining and electrodischarge machining processes.
