Abstract

An experimental study was made to investigate the role of cell voltage, electrolysing current, tool feed rate and additives to electrolyte, in the quality of drilled specimens, with respect to hole over-size, hole conicity and surface finish. Tests were carried with the objective of finding the operating conditions of electrochemical drilling (ECD) which can lead to good accuracy and dimensional control of the products. The results are also compared with the available literature data Finally the effects of various parameters are discussed in some detail.
