A biomimetic microtexture tool for earthworm was designed. Based on the surface morphology of earthworm, the microtexture of tool surface was processed by laser molding technology. The friction coefficient and wear of the bionic texture tool and the ordinary tool were studied through the comparative test of friction and wear, and the wear reduction mechanism of the bionic tool was analyzed. The cutting test of longan branches with different diameters was carried out by the selfmade cutting test platform to verify the wear reduction characteristics of the bionic cutting tools. The results showed that the optimized process parameters of the bionic laser forming tool were as follows: laser power was 75W, laser scanning speed was 4.8mm/s; the actual size of the microtexture of the bionic cutter was 138.3m wide and 33.5m deep. Compared with ordinary cutting tools, the texture bionic cutting tools showed the minimum friction coefficient of 0.2619 and the volume wear amount of 616.70mm3 when the groove spacing width was 1.6mm under the load of 400g, which had obvious wear reduction characteristics. With the increase of load, the wear mechanism was gradually changed from adhesive wear and microcutting wear to the complex wear forms of abrasive wear and oxidation wear. When the wear was stable, the required cutting times of 1.6mm texture bionic tool were 50~55 times higher than that of ordinary tool (45~50) times, and the stable times of 1.6mm texture bionic tool in cutting the wear area of branches with a diameter of 10mm, 15mm and 20mm were 35~40,45~50 and 50~55 respectively. The larger the diameter of the branch was, the more obvious the antiwear effect of the texture tool was.
