| Abstract |
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. |
