摘要

高硅铝合金材料因其优良的热导性能和较高的比强度而被广泛用于航空器热防护结构，但由于内部增强相硅颗粒的存在，导致材料加工困难。纵扭超声振动辅助微量润滑切削对改善均质材料的可加工性有明显优势，但对高硅铝合金材料的加工应用仍需进一步研究。本文利用单因素试验方法，探究纵扭超声振动辅助微量润滑铣削Al–50% Si（质量分数）合金时，不同切削参数对切削力、切削温度及工件表面质量的影响，并与微量润滑辅助铣削、纵扭超声振动辅助铣削和传统铣削对Al–50% Si合金切削性能进行对比研究。结果表明，LTUVAM MQL切削效果最佳，LTUVAM 与MQL次之，CM最差。本研究为高硅铝合金的高效、高质量加工提供了重要参考。

Abstract

High-silicon aluminum alloys

due to their excellent thermal conductivity and high specific strength

are crucial in aerospace thermal protection structures. However

the silicon particles within these alloys complicate machining processes. Longitudinal-torsional ultrasonic vibration-assisted minimum quantity lubrication (LTUVAM MQL) cutting has proven effective in enhancing the machinability of homogeneous materials

but its application in high-silicon aluminum alloys requires further study. In this research

single-factor experiments were conducted to investigate how different cutting parameters affect cutting force

temperature

and workpiece surface quality during LTUVAM MQL milling of Al–50% Si (mass fraction) alloys. Comparisons were also made between the machining performances of LTUVAM MQL

minimum quantity lubrication (MQL) milling

longitudinal-torsional ultrasonic vibration-assisted milling (LTUVAM)

and conventional milling (CM) for Al–50% Si alloys. The results indicated that LTUVAM MQL offered the best cutting performance

followed by LTUVAM and MQL

with CM being the least effective. This study provides valuable insights and important references for improving the machining efficiency and quality of high-silicon aluminum alloys.
