Abstract

This paper deals with the grinding energy distributions in wheel-workpiece contact zone and the wear behaviors of grain cutting edges in cBN deep grinding. By measuring the tangential grinding force distribution in the grinding zone, the grinding energy distribution form could be approximated to be triangular. However, the grinding energy distribution forms changed a little occurring workpiece burn. The wear behaviors of the grain cutting edges were observed by a Scanning Electron Microscope (SEM) and quantitatively evaluated in terms of attritious wear flat percentage. It is shown that the variation of the grinding energy distributions has an effect on the cutting edge wear characteristics.
