摘要：Through fabricating the micro-textures to improve surface property, the surface texturing technology has become a widely used way to prepare the functionalized surface. This study proposed a surface texturing method of one-dimensional ultrasonic vibration-assisted turning to generate micro-textured end face. The generation principle for the micro-textured end face was presented through the description of cutting conditions, the theoretical analysis of textured features, and the simulation prediction of surface topography. The polycrystalline diamond cutting tools with different clearance angles (7 degrees and 20 degrees) and nose radiuses (400 mu m, 200 mu m, and 100 mu m) were used in the experimental tests to investigate the influence of tool geometry on the micro-dimple features. The results show that the micro-dimples with different sizes and shapes can be successfully fabricated on the end face of Copper 1100. Same as the theoretical analysis and simulation prediction, through changing the cross-sectional profile of dimple along cutting direction, the clearance angle and the radius of observed point were verified to play a key role in the shape of micro-dimple. The oval-like dimples and the scale-like dimples can be respectively manufactured under the different intersection states between the flank face and the cutting trace. It was also confirmed that by choosing proper nose radius and the corresponding feed rate, the textured surface covered by micro-dimples of different widths can be generated. This texturing method used for fabricating the micro-textured end face was verified to be feasible and efficient, which laid a foundation for further research on the application of the textured surface.
