摘要:综述了钛合金、镍基高温合金及碳纤维增强复合材料等典型航空难加工材料超声振动辅助加工现状,在刀具上施加一维或二维超声振动可以提高航空难加工材料的切削加工性,具体表现为切削力降低、表面粗糙度改善、刀具磨损降低等。试验发现二维超声振动在切削航空难加工材料时效果更加显著。试验表明,未来开展超声振动加工与其它方式的复合加工将是进一步提高航空难加工材料切削加工性的有效手段。

Abstract:The present situation of ultrasonic vibration assisted cutting of difficult to cutting materials for aviation,titanium alloy,inconel alloy and carbon fiber reinforced polymer composite,is summarized.The machinability of these materials is improved by applying onedirection or twodirection vibration on the cutting tool.The cutting forces are decreased,the surface finish is improved and the life of cutting tool is prolonged.The experiment found that the twodimensional ultrasonic vibration in the cutting of aviation difficult to process the material more significant effect.Ultrasonic vibration combined with other method will be an efficiency way for improving the machinability of difficult to cutting materials for aviation.
