Abstract—Grinding is one of the main methods of precision machining. Grinding wheel wear, dynamic performance of the manufacture equipment, geometric accuracy and surface quality of work piece are greatly influenced by grinding forces, so some considerable research developments in calculating grinding force were made by various authors. Grinding forces are composed of chip formation force and sliding force. In surface grinding a new mathematical model of grinding forces is developed. Effectiveness of this model is proved by comparison of the experimental results and the model calculation results. Static chip formation energy and dynamic chip formation energy are mainly divided chip formation energy, which is mainly influenced by heat in the metal removal process,shear strain rate and shear strain. By analyzing the relationship between specific chip formation energy and chip formation force a formula for calculating the chip formation force is proposed. A new formula for calculating sliding force considering the influence of processing parameters on friction coefficient is obtained as a combined achievements of other researchers. By using Simulink software the experimental data’s are validated. Thus validate the correctness and effectiveness of proposed grinding force model.
