| Abstract: | The grinding force signals during grinding Si 3N 4 ceramics are verified by using digital signal processing (DSP) method. The results indicate that the distribution regularity of grinding force signals during grinding Si 3N 4 ceramics are different from that during grinding metal and other non metal materials, the grinding force signals of Si 3N 4 ceramics are periodic vibration signals with stationarity and ergodicity which don't follow the normal distribution in general. |
