Abstract
Machining accuracy is one of the most important criteria of electro discharge drilling (EDD) processes and this phenomenon is serious due to excessive electrode wears. In this study, the workpieces were machined with regard to EDD parameters to obtain blind holes. The machining accuracy was analyzed experimentally based on machining depth and shape of the holes. Experimental results were assessed by statistical methods such as analysis of variance and regression analysis. In addition, grey relation analysis was used to determine optimal machining condition and to improve the machining accuracy. It has been observed that working current is the determinative parameter. The lower working current and the higher pulse time are suggested to obtain the more accurate shape of the drilled holes in EDD of materials.
