Abstract

Abstract

To solve the problems of low elastic modulus and large elastic deformation when grinding titanium alloy with diamond grinding wheel, the force of grinding wheel was analyzed theoretically. Based on the chip separation criterion and the material friction properties, the cutting force model of titanium alloy grinding was established, and the cutting force state of a single abrasive particle was simulated by finite element method. The grinding experiment of titanium alloy was designed to study the influences of process parameters on the grinding forces of grinding wheel. The results show that the grinding force decreases with the increase of grinding speed. When the feed rate and the grinding depth increase, the grinding forces increase. When the grinding process parameters are changed, the change trend of tangential and normal grinding forces of the grinding wheel is roughly the same, and the ratio of the tangential and the normal force is 0.29～0.37. The variation trend of the theoretical value of grinding force is basically consistent with the experimental value, and the average value of the relative error between the two is within 5%, which verifies the correctness of the theoretical model of grinding force.
