Abstract
Grinding wheel wear equation for optimization of grinding process has been given in the form of the equation representing the relationship between grinding ratio and feed rate. However the other factors (work material, wheel, wheel speed, etc.) which affect to the wheel wear, seem not to be taken into consideration. In this paper, the wheel wear equation in abrasive cut-off operation is presented, in which chemical compositions and mechanical properties in work materials, abrasive grain, grain size, grade and wheel speed are treated as independent variables together with the feed rate, using input and output data given by the experiments and GMDH (Group Method of Data Handling) algorithm with successive determination of polynomial trends. As the results, the wheel wear equation can be obtained, of which construction is rather simple and accuracy is satisfactory.
