| Abstract: | High-speed single-grit grinding tests were carried out for 45 and 20Cr steels. The plastic upheaval, the area removal ratio and chip morphology, as well as the effects of grinding speed and grinding sectional area on the single-grit grinding forces have been studied. The friction coefficients under different grinding conditions have been obtained using the experimental results and the model of friction coefficient. The effects of grinding speed, work material and grain type on the friction coefficient have been discussed. |
