Abstract

The present paper reports the results of an experimental program to study the influence of process parameters on the side gap value in the electrochemical drilling (ECD). Twenty-Seven tests were performed on an experimr ental test rig using mild steel workpieces. A 3' factorial design is used to,study the influence of feed rate, applied voltage and tool land on the side gap width. An empirical equation for the calculation of the side gap was presented which allows computing of the gap width within a tolerance of .05 mm. to 0.15 mm. Furthermore, this experimental techni-que will contribute towards the selection of optimum process conditions in the electrochemi-cal drilling processes.
