  • Research on Microscopic Grain-Workpiece Interaction in

    Grinding is regarded as a special multiple edge cutting process which can be decomposed into grain-workpiece interface chip-workpiece/bond interface and bond-workpiece interface at microscopic level. The grain-workpiece interface which resembles a micro-cutting process directly modifies the workpiece surface and dominates all the output measures of a grinding process.

    Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.
