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.
