Finite Element Simulation of Grinding Performance and Grain Shapes in Grinding Superalloy-Inconel

The influence of different grain shape on the grinding characteristics was simulated based on DEFORM in grinding superalloy-incone. The grinding force, heat flux and maximum grinding temperature were studied in different grain shapes. Results indicated that increasing of the edges number of the multi-pyramid, the resultant force F, normal grinding force Fz and tangential grinding force Fy were uptrend, but the grinding force in feeding direction was downtrend. Heat flux of grain was small in triangular pyramid, rectangular pyramid, pentagonal pyramid, hexagonal pyramid. The temperature area of cone and multi-pyramids was larger than others. The influence of the grain number of edges, the maximum grinding temperature appeared uptrend overall. Keywords-grain shape; grinding force; grinding temperature; heat flux; superalloy-inconel718.
