Abstract
Electric discharge machining properties of some biometals, namely, Co-Cr alloy, two kinds of stainless steel (SUS 304, SUS 316L), and pure titanium were investigated. Co-Cr alloy and two kinds of stainless steel had similar machining properties. The machining speed, the surface roughness, and the clearance between the electrode and the metal increased with the increase of pulse magnitude from 4A to 16A. Pulse on time also had an effect on the machining speed, and there was a suitable pulse on time for each pulse magnitude. The electrode elimination ratio increased with the increase of pulse magnitude, and decreased with the increase of pulse on time. Pure titanium showed very low machining speed and a high electrode elimination ratio compared with the other alloys. The machining speed increased with the increase of pulse magnitude and pulse on time. The effect of pulse magnitude and pulse on time on other machining properties was similar to that on other alloys.
