Creep-feed grinding with intermittent dressing a using CBN-wheel

Creep-feed grinding is an effective machining process to increase the productivity of difficult-to-machine materials. However, this method has some problems, i.e., the increase in the grinding force and the occurrence of grinding burn caused by the excessive attrition of grain cutting edges. In this study, Creep-feed grinding with intermittent dressing using a CBN-wheel is proposed in order to solve these problems. Through the experiments it is confirmed that this method is effective to suppress the increase of grinding force and is superior to Creep-feed grinding with continuous dressing because of a smaller consumption of the grinding wheel and the dresser.
