Single grit grinding is the simplified model to abstract the macro scale grinding. Finite element analysis is a strong tool to study the physical fields during a single grit grinding process, compared to experimental research. Based on the dynamic mechanical behavior of 2Cr12Ni4Mo3VNbN steel and the mathematical statistics of abrasive grit, modeling of the single grit grinding process was conducted by using commercial software AdvantEdge. The validation experiment was designed to validate the correctness of the FEA model by contrast with grinding force. The validation result shows that the FEA model can well describe the single grit grinding process. Then the grinding force and multi-physics fields were studied by experimental and simulation results. It was found that both the normal and tangential grinding forces were linearly related to the cutting speed and cutting depth. The maximum temperature is located in the subsurface of the workpiece in front of the grit, while the maximum stress and strain are located under the grit tip. The strain rate can reach as high as about 10(6) s(-1) during the single grit grinding,which is larger than other traditional machining operations.
