Ultrasonic elliptical vibration-assisted micro-texturing

Abstract

Various micro-texturing techniques are used to generate the surface topography. However, conventional methods are inherently difficult to adapt for efficient production of micro-textures on cylindrical surface. In this paper, an ultrasonic elliptical vibration-assisted (UEVA) cutting technique based on discussed control parameters is proposed to fabricate the micro-texture on cylindrical surfaces. In the proposed UEVA micro-texturing method, a control model is developed based on shape and distribution parameters for the micro-texture. The locus of UEVA cutting is actively controlled with this EVA model to generate the micro-texture. The simulation model based on the proposed micro-texturing method is developed to predict the topography of the generated micro-texture. The cutting experiment to produce the micro-texture is conducted to verify the established control model. A comparison of the obtained results shows that the proposed UEVA micro-texturing method can be used to predict and generate the micro-texture on the cylindrical surfaces.
