Get PriceMechanical effects and proper grinding result in a compressive residual stress at the surface. This is beneficial for fatigue. Thermal effect produces the opposite effect, with a residual tensile field at the surface. As the part is locally heated, the surface layer expands, but it is constrained by the lower undisturbed material.
Get PriceJan 01, 2012· An even simpler formula that's used in calculations in just about every grinding process is the specific material-removal rate, Q', known as "Q-prime." Q' = a e × v w. where a e is the DOC measured in mm and v w is the feed rate measured in mm/sec. The specific mrr is the total mrr per unit width of the grinding wheel.
Get PriceThe abrasives consist of several chemical and mineral ingredients and the formula varies depending on the hardness of the material the wheel is intended to grind, polish or cut. There are two types of abrasive grains used to make grinding wheels.
