-Surface speeds involving grinding are very fast. 3 types of action Cutting, rubbing and plowing actions occur (a) (b) Grinding Process. Grinding Forces A knowledge of grinding forces is essential for: -Estimating power requirements. -Designing grinding machines and work-holding fixtures and devices. -Determining the deflections .

A grinding wheel's surface texture has a strong influence upon its grinding performance. This is clearly evidenced by the increase in grinding forces, power consumption, and cutting zone temperatures as a wheel wears [Butler and Blunt, 2002]. If the surface texture of a grinding wheel could be measured and quantified, then it could be

The material is held in place while the grinding surface moves across or is lowered into the material. Creep feed grinding is an adaptation of surface grinding which introduces a moving stock material into the path of a rotating abrasive wheel. This system then removes the material to the level of the grinding surface and no further.
