Abstract: In order to study the influence of micro-groove structure precision grinding, based on grinding wheel dressing and grinding kinematics, a grinding simulation model for the micro-groove structural surface is established. The influence of dressing, grinding parameters and pitch length on the profile of micro-groove structure was analyzed systematically, the grinding conditions for forming complete or interfering micro-groove profile are described, the profile and size of micro-groove are predicted, and the grinding test is carried out on carbon steel. The test results are consistent with the trend of the simulation model. The profile and size of the micro-groove structure are greatly affected by the grinding depth and the pitch length, and the influence on the dressing depth and the dressing overlap rate is small. At the same time, the test is verified by simulation. The simulation result of micro-groove has an average size error of 7.61%, which has high precision and reliability.
