Investigations show decreased tool wear in titanium machining with reduced oxygen, indicating improved efficiency.
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%.
