Abstract
Drilling micro holes on various engineering materials have been performed using electrochemical discharge machining (ECDM), especially non-conductive material. A predefined and controlled work material feeding is essential and plays a crucial role during drilling. Thus various feeding approaches have been developed and investigated for the ECDM process. The adaptive tool feeding system in the ECDM process has specific features to fulfill all the relevant requirements for the ECDM process. This system is rarely found in the published literature due to its complexity in design and operation. Therefore, the present research explains the process mechanism of an adaptive tool-feeding system for ECDM. Extensive experiments are performed to investigate the effect of the working gap, tool feed, and dwell time on machined hole depth and hole entrance diameter. A clear process mechanism is presented for all theinput process parameters during the machining process. Besides, multi-criteria optimization is performed to obtain the optimum values of process parameters.
