Combination of two machining processes has possibility to increase the productivity. This kind of approach is worthy to be tried especially for the machining of so called difficult-to-machine materials. In this study, cutoff and groove grinding with diamond wheel is combined with electric discharge machining. The effect of this new machining process is experimentally investigated in grooving and cutoff operations of cemented carbide, sendust, and several kinds of ceramics. Experimental results show that this process is effective for some materials to decrease grinding forces, which makes it possible to increase the workpiece speed. In addition, effect of the combination on the wheel wear, surface roughness, and geometrical accuracy of the workpiece is investigated.
