Abstract:

 


In the present study, a comparative study of hole-EDM drilling of die steel, namely as DIN 1.2080 using electrical discharge machining method was performed in order to discover the effects of coolant types, namely distilled-water, kerosene and water. The electrical parameters of electrical discharge machining process were taken as constant. the performance parameters were defined as machining speed, electrode wear, surface roughness value (Ra) and white layer thickness. The experimental results reveal that the increasing the current causes decreasing in machining speed, increasing in white layer thickness, increasing in electrode wear and decreasing in surface quality of electrical discharge machining process. The distilled-water has comparatively better results than the other coolant types. The results indicated that machining speed 101 mg/min, electrode wear 4,9 mg/min and surface roughness value Ra 2,7 μm were obtained by using distilled-water at 10 A current level.
