A novel method is reported for predicting the distribution of normal and tangential grinding forces in wheel and workpiece contact zone or along their contact arc. This work was motivated by the need to obtain the maximum force acting on individual active abrasive grains for establishing the probability of grain fracture and pullouts due to this force. Horizontal and vertical forces measured in the transient cut-in or cut-out stage of a grinding pass are utilized in this method to predict the horizontal and vertical forces acting on each portion of the contact arc. And then these forces are subsequently converted to tangential and normal forces per unit length along the arc to obtain the force distribution. To illustrate the application of this method, forces measured in the transient cut-out stage in the grinding of tungsten carbide with electroplated diamond wheels were employed to predict the force distribution, which was further applied to predicting the transient grinding power at the cut-in and cut-out stages. The predicted power was found to match very well with the measured power.
