In grinding process an emery or corundum wheel is used as the cutting tool. Emery and corundum are naturally found abrasives and are impure form of aluminium oxide Al2O3. A grinding wheel is made up of thousands of tiny abrasive particles embedded in a matrix called the 'bond' An abrasive is an extremely hard material second in hardness ...
Grinding process quality, accuracy and the resulting workpiece surface quality were affected by the forces in grinding. Grinding forces consist of frictional force, chip forming force and ploughing force respectively by rubbing, cutting and ploughing actions. All the three forces are greatly dependent on process parameters [12].

A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process.
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.
