Study on High-depth-of-cut Grinding (2nd Report)

Creep-feed grinding has been considered to be far more advantageous than the conventional swing grinding, especially with regard to wheel wear. However, the validity of the inference has not yet necessarily been made clear experimentally. In this study, some characteristics of wheel wear in creep-feed grinding were investigated experimentally comparing with the ones of the conventional swing grinding under similar metal removal rate conditions. The results obtained here are as follow : (1) Creep-feed grinding is not necessarily more advantageous than the conventional grinding with respect to attritious wear of the grinding wheel. (2) Creep-feed grinding is effective for holding the sharp profile of the grinding wheel due to reduced impact force at the edges of the work.
