In this study a comprehensive model to predict micro grinding forces is discussed and compared with experimental data of micro grinding Based on modeling techniques of thermal and mechanical deformation on the micro grinding zone that were presented in Park and Liang [1] a model was developed to predict micro grinding forces incorporating material
The diamond wheel is commonly used in ultraprecision grinding in the semiconductor and microelectronics industries Wang et al 2018 Tawakoli and Rabiey 2008 found through the grinding experiment of the structured CBN grinding wheel that the surface structure can reduce the friction between the grinding wheel and the workpiece surface thus

The above research only discussed the surface processing of brittle materials without analyzing the processing brittleness force Furthermore Li et al [25] obtained theoretical expressions for the microgrinding forces through the study of friction ploughing and crack initiation by silicon carbide RB SiC ceramics Hecker et al [26] derived a coupling function of
Microgrinding is a material removal technique by means of mechanical force used for machining pins and grooves with small dimensions and for obtaining flat surfaces with very fine finishing The main reason for this is that the chip size in microgrinding is very small because cutting is realized by means of micrograins
The critical microgrinding depth of SiC material is 65 nm; thus several microgrinding depths of models in simulation are 20 nm 30 nm 40 nm and 50 nm As shown in Figure 4 the corresponding tangential forces are μ N μ N μ N and μ N respectively; and the homologous normal forces are μ N 0
