Ti-6Al-4V合金的可加工性一直是工业上的一个挑战，尽管由于其机械性能，特别是其强度重量比，该材料广泛应用于航空航天和医疗行业。为了提高Ti-6Al-4V合金车削加工的可加工性，提出了一种激光和超声辅助混合加工（LUAM）技术。这与超声辅助加工（UAM）、激光辅助加工（LAM）和常规车削（CT）进行了比较。结果表明，与CT相比，UAM和LAM可以降低切削力和表面粗糙度（Ra）。然而，这些主要是在最低切削速度范围内实现的。混合LUAM工艺具有更大的切削速度和切削深度范围，这是由于混合工艺的综合减力和热软化效应。
The machinability of Ti-6Al-4V alloy has been a constant challenge in the industry, although the material is widely used in the aerospace and medical industries due to its mechanical properties, particularly its strength-to-weight ratio. The current research presents a hybrid laser- and ultrasonic-assisted machining (LUAM) technique to improve the machinability of Ti-6Al-4V alloy in a turning process. This is compared with ultrasonic-assisted machining (UAM), laser-assisted machining (LAM), and convectional turning (CT). The results reveal that UAM and LAM can reduce the cutting forces and surface roughness (Ra) compared to the CT. However, these are achieved mainly at the lowest range of cutting speeds. The hybrid LUAM process demonstrates process improvement with wider range of cutting speeds and depths of cut, which is achieved due to the combined force reduction and thermal softening effect by the hybrid process.
