Cutting tool suffers rapidly during machining titanium-based alloys due to low thermal conductivity. Thus most of the heat is concentrated on the tool rather than chip during machining. To overcome this problem, a suitable cutting parameter, tool geometry, and sustainable methods are necessary. This paper presents the effect of MoS₂ solid lubricant (SL), cutting speed, and nose radius during turning of Ti-6Al-4V alloy using the TiAlN coated carbide tool. The experiments are performed at different cutting speeds, nose radius, and flow rates of solid lubricant to study tool wear, surface roughness, and chip morphology. The results show that the use of solid lubricant reduces the tool wear (37%), and the surface roughness (65%) compared to the dry cutting. Similarly, the effects of nose radius and cutting speed have also been studied for both conditions.

由于钛合金的热导率低，切削刀具在加工钛基合金时会迅速遭受损失。因此，在加工过程中，大部分热量集中在工具上，而不是切屑上。为了克服这个问题，需要合适的切削参数，刀具几何形状和可持续的方法。本文介绍了MoS ₂的作用使用TiAlN涂层硬质合金工具切削Ti-6Al-4V合金时的固体润滑剂（SL），切削速度和刀尖半径。实验在不同的切削速度，刀尖半径和固体润滑剂的流速下进行，以研究工具的磨损，表面粗糙度和切屑形态。结果表明，与干切削相比，使用固体润滑剂可减少刀具磨损（37％）和表面粗糙度（65％）。同样，还研究了两种情况下刀尖半径和切削速度的影响。
