Effect of crystallographic orientation on residual stress ...

In the micro-grinding process, thermal stress history is obtained considering a single loading pass. However, the mechanical loading is repeated, because the grit travels at a speed of (V w + V s) which is much higher than the feed rate V w. Moreover, the contact length l c is larger than the average distance between active grits l 0. The ...

Cylindrical Grinding Process | Microinches to Microns ...

A cylindrical grinding process finishes most wheel spindle surfaces. It is essential that this grinding process leave a surface finish that is smooth and free of defects with minimal runout. No grinder produces a perfect surface. Grinder wheel runout, improperly dressed wheels and fixture vibrations can cause chatter on the spindle surface finish.
