WebFeb 1, 2024 · It is observed from the figure that the flank wear at a milling length of 60 m in the UAM was about 34% less than that in the CM, and the tangential and radial forces were significantly smaller in the former than the ones in the latter. As the milling length reached 240 m, some defects such as coating shedding and tool tipping occurred in the CM. WebHu Gong. Publications 46. h-index 17. Citations 856.
