Biomimetic studies have shown that the micro-textures of pits and grooves have much excellent properties such as drag reduction, noise reduction and self-cleaning. It is of great significance to realize micro-texture precision machining to improve the product performance. However, the current micro-texture machining methods have the problems of poor adaptability of the reference surface, high machining cost and long processing cycle. Therefore, taking the V-grooving as the target micro-texture, this paper presents a layered elliptical vibration assisted cutting micro-texture method, and realizes the machining of the V-grooving on the surface of the workpiece. Firstly, according to the trajectory characteristics of elliptical vibration, the morphological parameter model of V-grooving was established, and the relationship between the maximum scallop height and the cutting speed was derived. Secondly, according to the machining depth of V-grooving, designed
layered elliptical vibration assisted cutting path; Finally, the V-grooving machining experiment was carried out, and the obtained V-grooving is compared, which verified the theoretical analysis of the topography model. It shows that the layered elliptical vibration assisted cutting of the V-grooving can reduce the cutting force and inhibit the generation of burrs.
