Experimental Research on Grinding Force of HIPSN Ceramics with Diamond Grinding Wheels

In this paper studies are made on the internal grinding of HIPSN ceramics with diamond grinding wheels in different working conditions,the change characteristics of grinding force during grinding are researched.The grinding force experience formula is derived by means of experimental results.By the rotation dynamometer,the experiment with different speed of grinding wheel,different feed rate and working piece speed have been carried out.The results of experimental dates in different working conditions are obtained.Conclusions are drawn as follows.Through the experimental results,the grinding force ratio of HIPSN is obtained as Fn/Ft=6～11.The essential differences of the material removal mechanism between ceramics and metals have been analysed.According to the grinding force experience formula,The results which are affected by speed of grinding wheel,feed rate and working piece speed are received.
