Abstract Titanium alloy have excellent properties such as low density, high strength, and good oxidation resistance, which make them difficult to process. Abrasive belt grinding is an important method for precision machining of titanium alloy, which can obtain good machining accuracy and surface quality. A series of experimental studies were carried out on the surface roughness of TC17 titanium alloy under different process parameters, and the influence of feed speed, belt linear velocity and downward pressure on the surface roughness was explored. In order to predict surface features and other information more efficiently, corresponding software was developed. The experimental results show that the surface roughness first decreases and then increases as the belt linear velocity increases, and increases as the feed speed increases, while the downward pressure increases, the surface roughness value first decreases and then increases. The degree of fineness of the wear scar shows a trend of first increasing and then decreasing or first decreasing and then increasing with the process parameters. The prediction results of the developed software with a prediction error of less than 10% accounted for 92.19%, and the minimum error reached 0.35%.
