【Abstract】 The cooling performance of the low temperature field used in wet grinding is modeled based on FEM code ABAQUS. And the temperature contour map of wet grinding temperature field is obtained. Compared with grinding experiments, the simulation result of FEM model is proved to be right. The study results show that the low temperature wet cutting grinding fluid performs better than the traditional cutting fluid, and it has better characters in cooling ability, restraining the thermal expansion of workpieces and improving the machining accuracy.更多还原
