在可替代性弱且常被用于制造航空发动机关键部件的前提下,钛合金等难加工材料的高效高质切削面临挑战.针对钛合金Ti-6Al-4V加工表面完整性不佳和使役性能有待提升难题,开展了钛合金Ti-6Al-4V的高速车削试验,分析了高速超声振动切削技术对钛合金Ti-6Al-4V表面完整性和已加工表面耐磨损性能的改善效果,进而为钛合金Ti-6Al-4V的高质量加工提供理论支撑.结果表明,相比于普通切削,高速超声振动切削有效降低了钛合金Ti-6Al-4V的表面粗糙度,提高了表面强度和表面残余压应力,以及增强了耐磨损性能.
Experimental Study on Surface Integrity and Wear Resistance of Titanium Alloy During High-Speed Ultrasonic Vibration Cutting
On the premise of weak substitutability and being often used to manufacture key components of aero-engine,high-efficient and high-quality machining of difficult-to-cut materials such as titanium alloys is facing challenges.Aiming at the problems of poor surface integrity and service performance of titanium alloy Ti-6Al-4V,high-speed cutting tests of titanium alloy Ti-6Al-4V were carried out,and the improvement of high-speed ultrasonic vibration cutting technology on the surface integrity and the wear resistance of machined surface was analyzed,thus providing theoretical support for high-quality machining of titanium alloy Ti-6Al-4V.The results show that compared with conventional cutting,high-speed ultrasonic vibration cutting effectively reduces the surface roughness,and improves surface strength,surface residual compressive stress and wear resistance of titanium alloy Ti-6Al-4V.
