摘要

在机械加工过程中，刀具和工件会承受很高的热机械负荷。因此，众所周知，氧化磨损取决于刀具和工件组合的选择。然而，在无氧环境中进行加工的情况却不为人知。为此，我们开发了一种方法来研究氧气在适当的 XHV 环境中的影响。研究表明，在使用未涂层硬质合金加工 Ti-6Al-4 V 时，氧气含量对工件的机械负荷和表面完整性有很大影响。在无氧气氛中加工，刀具磨损明显减少，刀具寿命延长了 170%。

Study of the effect of oxygen level on tool wear in machining Ti-6Al-4V

During machining, tools and workpieces are exposed to high thermomechanical loads. Consequently, it is known that oxidation wear is determined by the choice of tool and workpiece combination. However, machining in an oxygen-free atmosphere, is not known. For this purpose, a method was developed to investigate the influence of oxygen in an XHV-adequate atmosphere. The investigations show a significant influence of the oxygen content on the mechanical loads and the surface integrity of the workpiece when machining Ti-6Al-4 V with uncoated cemented carbide. Machining in an oxygen-free atmosphere resulted in significantly less tool wear, which increased the tool life by 170%.
