  • Grinding Operation an overview ScienceDirect Topics

    For surface grinding operations, the process parameters, i.e. the linear feed, the cross feed, and the depth of cut, have a direct influence on the roughness of the ground surface. Higher values of any of them would result in a higher material removal rate, and therefore, a Chapter 16: Grinding Wheels and Operations Cutting ,2020-6-29 · Grinding pressure. Grinding pressure is the rate of in-feed used during a grinding operation; it affects the grade of wheel. A general rule to follow is that as grinding pressures increase harder wheels must be used.
