摘要
在航空制造领域,高温合金、钛合金、复合材料等难加工材料高效低损伤加工一直是制约行业产能的瓶颈问题。随着我国制造业的不断升级,智能制造、先进数控、先进刀具、先进冷却等前沿技术已在难加工材料加工方面得到了广泛应用,然而传统连续切削模式下难加工合金切削线速度仍未能得到实质性突破,限制了其产能的进一步提升。近年来,出现了高速波动式超声加工技术,该技术将传统连续切削模式升级为高速断续切削模式,不仅打破了传统振动切削技术的加工速度限,而且实现了难加工合金材料降力降热高速精细加工,大幅提升了其加工精度、表面完整性和加工效率。在简要概述高速波动式超声加工的提出背景和基本原理基础上,重点介绍了高速波动式超声加工技术在车削、铣削、制孔3方面的工艺原理、工艺效果和应用进展。最后,对高速波动式超声加工技术的工艺适应性优化和应用前景优势进行了展望。
In the field of aviation manufacturing,high-efficiency and low-damage processing of difficult-tomachine materials such as superalloys,titanium alloys and composites has always been the bottleneck restricting the industry production capacity.With the continuous upgrading of China’s manufacturing technology,frontier technologies such as intelligence,advanced numerical control,advanced cutting tools and advanced cooling have been widely used in the processing of difficult-to-machine materials.However,the traditional continuous cutting mode still fails to make a substantive breakthrough in cutting linear speed of difficult-to-machine alloy,which limits further improvement of its production capacity.In recent years,high-speed wave-motion ultrasonic machining technology has emerged.This technology upgrades the traditional continuous cutting mode to high-speed separate cutting mode,which not only breaks the machining speed limit of traditional vibration cutting technology,but also realizes the high-speed machining of difficultto-machine alloy materials and greatly improves its machining accuracy,surface integrity and machining efficiency.Based on a brief overview of background and basic principle of high-speed wave-motion ultrasonic machining,this paper focuses on the process principle,process effect and application of high-speed wave-motion ultrasonic machining technology in turning,milling and hole drilling.The process adaptability optimization and application advantages of high-speed wavemotion ultrasonic machining technology are also prospected in this paper.
