Identification of a grinding wheel wear equation of the abrasive cut-off by the modified GMDH

Abstract

A grinding wheel wear equation is identified by the GMDH (Group Method of Data Handling) algorithm with successive determination of polynomial trends containing interactive terms, considering chemical compositions and mechanical properties of work materials, abrasive grain, grain size, grade, wheel speed and feed. The established model enables the grinding to be predicted for all combinations of work materials, grinding wheels and grinding conditions, and serves as an aid in the optimization of the grinding process.
