    2020-12-1 · Pure electrolytic copper (99.9 %) of 10 mm diameter was utilized as tool electrode in a high accuracy CNC machine tool. Surface roughness was found to rise as gap current and duty factor rises. Surface roughness was achieved in the range of 2.30–3.33 μm by rotating electrode; in contrast, stationary electrode gave surface roughness in the range of 2.50–3.50 μm.
