It was confirmed by modern tribology and bionics that non high performance surface texture smooth morphology has better . Antifriction nature. It was founded by Solidworks to three-dimensional mod-eling of the bionic texture tool and use DEFORM-3D finite element analysis software. It was carried out three dimensional cutting simulation on the non-micro texture and micro texture ( pits, grooves) PCD tool under the same conditions, combing with the cutting force and cutting temperature for cutting performance a-nalysis. The results show that the size of the pits, grooves, micro texture can effectively improve the stress distribution in the cutting tool process. Then, different surface micro textures were put into in front of the PCD blade knife by rake of the laser processing method and cut experiment on a CA6136 lathe. Test results show that the surface quality of the groove type micro texture cutting aluminum alloy workpiece is better than that of untextured tool under the dry cutting conditions.%现代摩擦学和仿生学证实，具有一定非光滑形态的高性能的表面织构有更好的抗磨减摩性能。通过Solidworks对仿生织构PCD刀具进行了三维建模，利用DEFORM-3 D有限元分析软件，对无微织构和有微织构(凹坑、沟槽) PCD刀具在相同条件下进行了三维切削仿真，结合其切削力、切削温度进行切削性能分析。结果表明，一定尺寸的凹坑、沟槽微织构可以有效改善刀具在切削过程中的应力分布情况。然后，采用激光加工方法在刀片的前刀面置入不同微织构，在CA6136车床上进行切削实验。试验发现：干切削条件下，沟槽型微织构刀具切削铝合金工件的表面质量要优于无织构刀具。
