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.
