摘要

对钛合金可加工性的研究为降低钛合金因大量热积累而产生的加工难度提供了新的途径。为了提高可加工性,必须调节热积累和切削温度等关键因素。在本研究中,对Ti-6Al-4V进行车削加工,并通过连接两个喷嘴的涡流管提供冷却的CO2气体来降低切削温度。记录了切削力、切削温度和表面粗糙度随切削速度、进给量和切削深度的变化。随后,比较了不同切割速度下单喷嘴涡流管、干燥和压缩空气环境下的响应。切削力和表面粗糙度随切削速度的减小、进给量的增大和切削深度的增大而增大。切削温度随三个变量的增加而增加。所提出的冷却系统在切削温度和表面粗糙度方面提供了更好的结果,而与干切削相比,观察到略高的切削力

Machinability Study in Turning of Ti-6Al-4V under CO2-based Vortex Tube Cooling System
The study on the machinability of titanium alloys provides new ways to minimize the difficulty levels of machining the alloys due to substantial heat accumulation. To improve machinability, pivotal factors such as heat accumulation and cutting temperature must be regulated. In this study, a turning operation was performed on Ti-6Al-4V and the cutting temperature was reduced by supplying cooled CO2 gas through a vortex tube connected with two nozzles. Variations in cutting force, cutting temperature, and surface roughness with cutting speed, feed, and depth of cut were recorded. Subsequently, responses were compared for single nozzle vortex tube, dry, and compressed air environments at different cutting speeds. Cutting force and surface roughness followed a similar trend which increased with decreasing speed, and increasing feed and depth of cut. The cutting temperature increased with all three variables. The proposed cooling system provided better results in terms of cutting temperature and surface roughness, while a marginally higher cutting force was observed compared to dry cutting
