抄録

The electric discharge grinding of titanium was researched by R-C circuit on machining conditions, state of machined surface, change in the structure around the machined surface, etc.<br>The results showed that titanium could easily be rough-machined by electric discharge grinding, but the machining speed was greatly affected by the conditions such as source voltage, current for machining, capacity of condenser, circumferential speed of electrode disc, etc. For example, the machining efficiency increased with the rise of source voltage; however, the highest efficiency was found at some degree of current, condenser capacity, circumferential speed of the disc, etc. The efficiency decreased at either below or above that degree.<br>The machined surface was satin finished, being assembled of many discharge craters, and its degree of roughness was ordinary higher for higher machining speed. Some ground materials were slightly hardened by electric discharge machining; in particular, the hardness was distinguished around the machined surface for low disk speed.
