“…Meanwhile, it is considered to be a material that is particularly difficult to process due to the following characteristics: high strength, low thermal conductivity and easily adhering to the tool surface during cutting [2]. During turning Ti6Al4V with coated cemented carbide tools, it is found that high cutting temperature concentrates at the tool-chip interface adjacent to the cutting edge, where the highest temperature can exceed 1000℃, accelerating the formation of wear [3,4]. This restricts cutting speed and feed speed, and thus reduces the machining efficiency of titanium alloy.…”

Tool wear has great impacts on tool life and cutting parameter selection in the machining process. As ceramic inserts are widely employed in efficient machining, it is of great significance to predict accurately the wear of ceramic tools. Crater wear is one of the most significant tool wear modes when turning difficult-to-cut materials at high speeds. The purpose of this research is to demonstrate the forming and influence mechanisms of crater wear in Ti6Al4V turning with ceramic inserts while considering cutting temperature at the tool-chip interface. An effort is made to describe quantitatively the appearance of crater wear from the perspective of temperature distribution based on crater wear experiments under various cutting conditions. In order to obtain the cutting temperature distribution efficiently, an analytical temperature prediction model is used in this paper. Then a prediction model for crater wear depth and width considering the influence of the maximum temperature is developed. The maximum crater wear depth and width models are validated by a series of cutting experiments, and the outcomes prove that the proposed models are practical.Additionally, the influence of various cutting parameters on crater wear is discussed.The cutting speed has the greatest impact on crater wear, followed by the feed rate.Furthermore, this research can be used to improve cutting parameters for controlling crater wear.

Titanium alloys have been extensively applied due to their outstanding features, including high specific strength and corrosion resistance. However, the machining of these alloys presents challenges, leading to significant tool wear and reduced tool lifetime, ascribed to the difficult-to-machine features of Ti alloys. In the context of pursuing environmental sustainability and enhanced productivity, high-speed dry-cutting technology coupled with high-quality tool coatings are prospective. This paper comprehensively explores wear patterns and recent advancements in tool coatings for high-speed dry cutting of Ti-alloys. Key coating properties such as resistance to abrasion, adhesion, oxidation, fatigue, hot hardness, and self-adaptability are briefly introduced. Design strategies for enhancing micro-hardness, toughness, and adhesion, including nanocomposite, multilayer, and gradient architectures, are also discussed. Furthermore, the paper highlights several Boron (B) doped hard coatings as promising candidates for high-speed dry cutting against Ti-alloys, exploring the impact of B on microstructure, hardness, thermal stability, oxidation resistance, and lubrication. In summary, this work provides a systematic overview of novel B-doped tool coatings applied in high-speed dry cutting against Ti-alloys.
