For longitudinal grinding . when the grinding direction is parallel to the applied tensile stress the wheel grit depth of cut hmax has no effect on the flexural strength. 3. For transverse grinding . when the grinding direction is perpendicular to the applied tensile stress the flexural strength drops off when the wheel grit depth of cut hmax is increased beyond a critical value. 4. Each ceramic material appears to have its own critical hmax value. 5. The lapping and strength testing approach can be used to experimentally determine the effective depth of damage caused by grinding of ceramics. 6. With the knowledge of the depth of damage a strategy is proposed for high removal rate grinding including both roughing and finishing while still achieving maximum strength. References 1.
