Surface characteristics comparison between additively manufactured Ti6Al4V and wrought Ti6Al4V turned samples

Abstract

Abstract. This paper aims to contribute increasing the knowledge surrounding Ti6Al4V by making a comprehensive comparative analysis of surface characteristics between additively manufactured and conventionally wrought Ti6Al4V turned samples. The tests were carried out by varying the process parameters such as cutting speed and lubricant conditions (dry and cryogenic), and by keeping fixed the feed rate and the depth of cut. The comparison of these two manufacturing methods allows to explore how the different surface properties, such as roughness, microstructure and hardness, can change.
