摘要：
To further study the mechanism and rule of grinding force of 20CrMnTi steel, theoretical and mathematical model of the grinding force of single grits, maximum undeformed chip thickness, and the grinding force of tooth surface is established, which is on the basis of contact deformation zone based on Lawn indentation model and triangular cross section chip. Grinding force mainly comes from the chip deformation and friction, and the effect of grinding size exists. Grinding force increases with the increase of grinding depth, feed rate, material hardness, and top cone angle of abrasive grains. However, it decreases with the increase of grinding speed and grinding wheel diameter. In the wear process of grinding wheel, the change of grinding wheel characteristic parameters has a great influence on the grinding force. Based on the theoretical model analysis, the local grinding test of tooth surface is carried out. It also gives a detailed analysis on the residuals and F measure of the fitting curve to grinding force with variable under the different constant α situations. © 2018 Journal of Mechanical Engineering.
