Abstract
In order to apply the workpiece surface machining quality detection data to tool wear prediction, an experiment on the relationship between workpiece surface machining quality and turning tool wear was carried out. Firstly, the experimental parameters are selected, and the workpiece surface quality is determined as the parameter to study the tool wear law; Secondly, by changing the tool material and workpiece material, the change law of tool wear is analyzed, and the internal reason of blade initial wear is revealed; Finally, the relationship between workpiece surface machining quality and tool wear is analyzed by measuring workpiece surface machining quality parameters. The experimental results show that the relative hardness of workpiece material and tool is the main factor determining the wear speed of tool flank, and the tool geometry is the main factor of rapid tool wear in the initial stage. The workpiece surface roughness increases gradually with tool wear. When the tool enters the severe wear stage, it decreases slightly and then continues to increase. The outer diameter of the workpiece decreases with the tool wear in the initial stage, and then fluctuates and increases gradually. The influence of tool wear on the cylindricity error of shaft parts can be ignored.
