Abstract

The increasing use of Ti-5553 for aeronautical high-performance components has advanced the implementation of cryogenic cooling strategies. In this study, a tool wear experiment for machining Ti-5553 with uncoated cemented carbide was conducted under cryogenic cooling. The microscopic wear morphologies of the cutting tools were observed. Hence, a two-dimensional tool wear map, including three cutting elements, is proposed, and constructed. The mapping relationship between tool wear and the cutting parameters under LN₂ cryogenic was explored, and a method for determining the safe cutting area is presented.

用未涂层硬质合金对 Ti-5553 进行低温加工的刀具磨损分析和映射磨损

摘要

Ti-5553 越来越多地用于航空高性能部件，推动了低温冷却策略的实施。在这项研究中，在低温冷却下进行了用未涂层硬质合金加工 Ti-5553 的刀具磨损实验。观察了切削工具的微观磨损形态。因此，提出并构建了包含三个切削元素的二维刀具磨损图。_{探讨了LN 2}低温下刀具磨损与切削参数的映射关系，提出了一种确定安全切削区域的方法。
