Grinding or cutting is a process whereby an abrasive particle embedded in a rotating wheel or knife edge removes material from a workpiece by mechanical means. The grinding wheel can be attached to a horizontal or vertical spindle, and the specimen can be mounted on a table surface that travels in either a rotary or reciprocating direction.
It is important that the tensile strength of the material being processed is less than that of the abrasive. Other process-related variables that are important for this operation include the depth and speed of the cut, coolant flow, wheel speed, and particle removal/filtration. A non-process-related variable that is often overlooked, yet can drive the overall grinding performance, is coolant chemistry.
