Cutting performance and surface quality of Ti-6Al-4V by longitudinal ultrasonic vibration-assisted high-speed dry milling with coated carbide tools

Abstract: Longitudinal ultrasonic vibration-assisted high-speed dry milling (LUVAHSDM) is performed to improve cutting performance and surface quality of Ti-6Al-4V (TC4). Multifaceted comparisons are presented in milling results of AlCrN, AlCrSiN, AlTiN and AlTiSiN-coated tools in terms of milling force, milling temperature, tool wear, 3D surface roughness and residual stress. The results show that maximum milling force in both the feed and longitudinal directions rst decreased and then increased with increasing Al elem… Show more

“…AlTiN coatings possess higher thermal conductivity at an elevated temperature, while AlCrN coatings have excellent oxidation and abrasion resistance [21,22]. It was found that the hardness of coatings with Ti, Si, and Cr elements has a positive influence on the cutting tool life and cutting force when dry-milling Ti-6Al-4V [23]. Moreover, advanced arc PVD AlCrN coatings have been applied in the process of machining Ti-6Al-4V and have demonstrated enhanced frictional behavior and reduced cutting force [24].…”
