Description
Summary:In this study, electrical discharge hole drilling processes was applied to DIN 1.2379 tool steel by using single-channel brass electrode and dielectric liquid which possess various level of temperature. In the study, the machining parameters were kept constant and the effect of the dielectric liquid temperature on the performance parameters such as material removal rate, electrode wear rate, white layer thickness, surface roughness, overcut in diameter and taper at the tip was examined. The results show that the decrease of dielectric liquid temperature improves performance parameters. The material removal rate was increased nearly 30%, surface roughness value R a is improved from 4.8 to 2.7 μm, white layer thickness was decreased and the hole geometry is improved in terms of hole diameter and taper.
