Design and Development of Electro-Discharge Drilling Process

Abstract:

There still exist numerous difficulties in generating holes in super alloys, advanced materials and metal matrix composite materials. Electro-discharge drilling (EDD) is a proficient drilling process for the hole making and hole grinding resulting from its characteristics of being a conductive and a thermal process. The EDD process has been investigated with the developed set-up. A EDD set up has been designed and developed as part of the present investigation. The experiments have been conducted on the constant input parameters. This type of process is generally unstable, but its efficiency is very high. The process parameter has been compared with EDM process. The MRR of EDD process has been found to increase as compared to the EDM process. However, this process has a serious problem caused by the tool wear rate, which significantly deteriorates the machining accuracy.
