The Effect of the Relative Displacement between the Grinding Wheel and the Work on the Wheel Depth of Cut in Grinding Operation

The displacement of the relative position of the grinding wheel and the work at grinding operation is investigated. The true and the equivalent wheel depth of cut, the decrease of work radius, and the cutting residue are computed under the following assumptions : (1) The effect of the vibration can be ignored. (2) The relative displacement between the grinding wheel and the work is elastic and proportional to the grinding force. (3) The parallel movement of the work and the grinding wheel is caused by the grinding force. (4) The wear of the grinding wheel can be ignored. The analysis shows that the equivalent wheel depth of cut is equal to the amount of the wheel-head advance at each pass of grinding wheel when the number of passes is increased.
