Grinding Basics | NORITAKE CO.,LIMITED

The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.

Basic Grinding Theory 221 - Tooling U-SME

Basic Grinding Theory provides an overview of the general process of grinding . Grinding occurs at the point of contact between an abrasive wheel and a workpiece. Like any other cutting process, grinding removes material in the form of chips. In order for a wheel to grind properly, its abrasive grains must wear and self-sharpen at a consistent rate.

Grinding Theory and Adaptive Control Optimization ...

The abrasive grains of the grinding media represent thousands of tiny cutting edges that remove metal from the surface of the workpiece. As pressure is applied between the workpiece and grinding wheel, normal and tangential forces are generated. These forces cause the grain to cut into the workpiece and remove metal in the form of chips.
