  • In precision abrasive belt grinding process of titanium alloy aeroengine blade, the wear of diamond belt has a great influence on machining accuracy and surface quality consistency. To solve this problem, the simulation of the grinding process of titanium alloy with single diamond grain was carried out on ABAQUS. On this basis, the grinding experiments of titanium alloy blade with diamond abrasive belt was carried out. The results of simulation and experiment show that the temperature of friction contact point is more than 700 K in the range of grinding speed of 10~20 m/s, and that the temperature increases with the increase of grinding speed. It is also found that the wear degree of abrasive belt increases with the increase of grinding speed, which is consistent with the effect of grinding speed on the grinding temperature of friction contact point. The wear forms of M10/20 diamond belt are grain wear and grain shedding, and the adhesion of abrasive debris aggravates the wear of belt.
