It is generally expected that conventional grinding leads to tensile residual stresses, while compressive stresses are obtained with high speed grinding (HSG). In this paper, a finite element thermomechanical model for the calculation of residual stresses induced by a surface grinding process on a steel workpiece (AISI 52100) is presented.

A new simple model of grinding force in surface grinding is proposed in this paper. The model is based on the fact that the grinding forces are composed of chip formation force and sliding force. The formula for calculating the tangential and normal grinding force per unit width is obtained based on the classical formulas. The coefficients in the formula …

Typically, creepfeed grinding results in a lower undeformed chip thickness relative to surface grinding, thereby improving surface finish on the workpiece and reducing wheel wear. However, this advantage comes with a few drawbacks. Creepfeed grinding applications tend to draw more power and have higher forces.

A surface Grinding Machine is a machine in which a grinding wheel is used as a cutting tool for removing the material from the surface of the workpiece. It is also called an abrasive machining process where abrasives are placed on the surface and corners of the grinding wheel so as to do the finishing process with much more accuracy.
