Abstract
This paper investigates how EDM and ECM can be combined to give hybrid techniques that are capable of rapidly producing and finishing dies and moulds within a single machine. Firstly, a hybrid EDM/ECM machine which uses EDM to produce the roughing cut to the accuracy specified, then few seconds of ECM to give a smooth lustrous finish is described. Secondly, Electro-erosion-dissolution machining (EEDM), a process which utilises pulsed power in an aqueous electrolyte, thereby permitting both electrochemical dissolution and electro-discharge erosion within a single machine tool is discussed. This process is capable of using very low concentration electrolyte to give faster roughing than EDM and final finishing by electrolytic dissolution to give the required surface quality.
