Furthermore, the values predicted according to proposed model are consistent with the experimental data, with the average deviation of % and % for the normal and tangential force, respectively. This suggests that the proposed model is acceptable and can be used to simulate the grinding force for RBSiC ceramics in practical.

removal rate, grinding force, power consumption, specific energy, and grinding ratio. This process is time consuming, destroys the product, and is an indirect method of characterizing the wheel. Measuring the surface texture, however, would be faster and automatable, be completely noncontact, and give a direct characterization of the wheel.

the grinding wheel and the surface of the workpiece is introduced by the equation 1c2 = li2 + 1g2. The orthogonal combination of the contact length due to the deformation which would occur with zero depth of cut and the contact length due to the depth of cut is a new finding that clarifies for the first time the effects of the grinding geometry,

The grinding forces increases with increase in speed and depth of cut. SiC exhibits high grinding force compared to that of CBN wheel. In case of Diamond wheel it is even lesser. The specific grinding energy is high for SiC wheel followed by Diamond wheel and CBN wheel. The influence of coolant is also studied and the effect is marginal in both cases.

In centerless grinding, the workpiece is held between two wheels, rotating in the same direction at different speeds, and a workholding platform. One wheel, known as the grinding wheel (stationary wheel in the diagram), is on a fixed axis and rotates such that the force applied to the workpiece is directed downward, against the workholding platform.
