Abstract

Abstract: This study investigates the performance of micro-grooved polycrystalline diamond (PCD) tool in dry machining of Ti6Al4V titanium alloy. Regular micro-groove array was successfully fabricated on the rake face of PCD tools by a fiber laser. The effect of the micro-grooved PCD tools and the untextured PCD tools on cutting force, average friction coefficient, and anti-adhesion was studied in detail. It is found that better tribological properties of the tool–chip interface can be achieved by the micro-grooved PCD tools compared with that of the untextured PCD tools even under dry cutting conditions. Furthermore, the action mechanism of the micro-grooved PCD tools on the friction behaviors has been discussed and revealed by the tool-chip contact length, direction of micro-grooves, and formation of TiC.
