Abstract: We herein propose a cutting force model in a micro-dimple pattern process using the two-frequency elliptical vibration texturing (TFEVT) method. The TFEVT method decreases the cutting force compared to the conventional texturing (CT) method owing to the intermittent cutting behavior. The cutting force model in the TFEVT method is formulated, in which the shear angle is assumed as a transient and the transient area of cut of the micro-dimple is determined. The transient area of cut of the micro-dimple can be determined by obtaining the starting and ending time of cutting, while the shear angle can be determined by Cerniway’s hypothesis. Finally, the cutting force model was compared with the experimental cutting force value. The comparison results show that the cutting force simulation is in agreement with the experimental cutting force value. The experimental results also show that the cutting force in the TFEVT method is lower than that in the CT method.

Effect of surface texturing on friction reduction between ceramic and steel materials under lubricated sliding contact
TL;DR: In this article, the effect of micro-dimples on the frictional properties of a silicon nitride ceramic mated with hardened steel was investigated and it was found that the porosity depended greatly on the size and density of the microdimples, whilst the dimple shape did not significantly affect the friction coefficient regardless of rounded or angular profiles.
