“…The milling process is a subtractive process including a material removal at the work piece as well as an appearance of wear characteristics at the milling cutter [ 39 , 40 , 41 ]. Different mechanical, thermal, and chemical impacts are responsible for decreasing tool performance during tool life time [ 42 , 43 , 44 ]. Most frequently occurring wear causes for milling cutters are adhesion, abrasion and diffusion [ 45 , 46 ].…”

We report on milling and tool wear characteristics of hybrid additive manufacturing comprising laser powder bed fusion and in situ high-speed milling, a particular process in which the cutter mills inside the powder bed without any cooling lubricant being applicable. Flank wear is found to be the dominant wear characteristic with its temporal evolution over utilization period revealing the typical s-shaped dependence. The flank wear land width is measured by microscopy and correlated to the achievable surface roughness of milled 3D-printed parts, showing that for flank wear levels up to 100 μm a superior surface roughness below 3 μm is accessible for hybrid additive manufacturing. Further, based on this correlation recommended tool, life scenarios can be deduced. In addition, by optimizing the finishing tool start position and the number of afore-built layers, the milling process is improved with respect to the maximum millable angle for undercut surfaces of 3D-printed parts to 30∘ for the roughing process and to 40∘ for the entire machining process including finishing.

“…Molinari and Nouari [18] found that the temperature-sensitive diffusion process had the strongest effect on the wear rate, particularly at higher cutting speeds. Sun et al [19,20] studied the crater wear patterns of carbide tools and discovered that pressure and temperature had a significant impact on the wear rate when turning Ti6Al4V. To give a clear description, available wear models developed in the previous studies considering temperature variable are summarized in Table 1.…”

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.
