Surface Roughness Investigation in the Electrical Discharge Machining of Powder Metal Material

S. Abdurrahman CelIk

Abstract:
In this study, various EDM parameters (current, pulse on-time, pulse off-time, gap voltage) applied on a work piece made of Powder Metal (PM) methods. The work piece has similar mechanical properties with DIN 1.2379 material. Experiment specimen is hardened up to 60 Rockwell C average. Meanwhile with different electrode materials EDM process has been applied on the hardened material. Surface roughness Ra (μm) on specimens with different parameters and electrodes is measured. Then, surface roughness values are compared with the values in literature.
