摘要/Abstract

摘要： 钼镧合金是一种典型的难加工材料，在普通切削过程中极易引发材料脆性断裂和刀具磨损，难以获得高质量加工表面。超声椭圆振动切削技术是一种实现难加工材料超精密切削加工的有效方法。开展了钼镧合金金刚石切削实验研究，验证了超声椭圆振动切削对材料可加工性的提升作用，对比分析了普通切削和超声椭圆振动切削钼镧合金表面创成机制、切屑形成机制及刀具损伤机制。通过改变刀具椭圆振动轨迹，当椭圆轨迹取向角为160°时，实现了1 0351.9 nm的最大临界切削深度，相对于普通切削的最优临界切削深度52.5 nm，提升了197倍。普通金刚石切削过程，材料主要以脆性模式被去除。成形表面产生鳞刺缺陷，切屑剪切带的锯齿特征明显，且切屑与刀具接触面粗糙、产生明显撕裂，与此同时材料与刀具粘结严重。超声椭圆振动金刚石切削过程，材料主要以塑性模式被去除。成形表面鳞刺缺陷的产生被显著抑制，切屑剪切带的锯齿特征减弱，且切屑与刀具接触面光滑、无撕裂现象产生，材料与刀具的粘结得到有效抑制。分析表明，超声椭圆振动切削显著提升了钼镧合金可加工性、抑制了表面脆性缺陷和刀具损伤。本研究揭示了钼镧合金的材料去除机制，有助于推动钼镧合金在航空航天等领域中的应用。

Abstract: Mo-La alloy is a typical difficult-to-cut material, which is very prone to cause brittle fracture and tool wear in the conventional cutting process, making it difficult to obtain high-quality machined surfaces. Ultrasonic elliptical vibration cutting technology is an effective method for achieving ultra-precision cutting of difficult-to-cut materials. This research conducts diamond cutting experiments on Mo-La alloy to verify the enhancement effect of elliptical vibration cutting on material machinability and comparatively analyzes the surface generation mechanism, chip formation mechanism, and tool damage mechanism of Mo-La alloy in conventional cutting and ultrasonic elliptical vibration cutting. By changing the elliptical vibration trajectory of the tool, a maximum critical depth of cut of 10351.9 nm is achieved at an orientation angle of elliptical trajectory of 160°, which is 197 times higher than that of 52.5 nm in conventional cutting. In the conventional diamond cutting process, the material is removed mainly in a brittle mode. The scaly burr defects are generated on the forming surface. The serration feature of the chip shear band is obvious and the contact surface between the chip and the tool is rough with obvious tearing. At the same time, the material is severely adhered to the tool. In the ultrasonic elliptical vibration diamond cutting process, the material is removed mainly in the brittle mode. The generation of scaly burr defects on the forming surface is significantly suppressed. The serration feature of the chip shear band is weakened and the contact surface between the chip and the tool is smooth with no tearing phenomenon. The material adhesion on the tool is effectively suppressed. It is dictated that ultrasonic elliptical vibration cutting significantly enhances the machinability of Mo-La alloy, and inhibits surface brittle defects and tool damage. This research reveals the material removal mechanism of Mo-La alloy, which can help to promote the application of Mo-La alloy in aerospace and other fields.

Key words: Mo-La alloy, difficult-to-cut material, ultrasonic elliptical vibration cutting, ductile-to-brittle transition, material removal mechanism
