【摘要】：麻花钻钻孔是机械加工领域最为常用的孔加工方法。传统麻花钻钻孔加工中,特别是对一些难加工材料进行钻孔加工时,存在轴向力大、表面质量差等诸多问题。超声振动辅助钻削属于振动钻削技术的一种,即在钻孔过程中在麻花钻上施加大于15 k Hz的高频振动,钻头的周期性振动改善了切削刃工作状况,可在一定程度上解决难加工材料制孔难题。介绍超声振动辅助钻削技术的分类、技术特点和系统组成的基础上,从动力学研究、振动断屑理论研究、切削力研究、精度及加工质量研究、在新材料上的应用和超声振动钻削装置六个方面论述了超声振动辅助钻削理论和技术的国内外研究进展。基于超声振动辅助钻削技术的发展现状,结合航空航天等领域难加工材料制孔技术的需求,从理论研究、超声振动系统开发完善、新材料工艺研究、专用超声辅助钻削机床开发以及超声振动辅助加工规范标准制定等方面指出了现有研究和应用中存在的问题并对未来发展趋势做以展望。
[Abstract]:Twist drilling is the most commonly used drilling method in the field of mechanical machining. There are many problems such as large axial force, poor surface quality and so on in the traditional drilling process of twist drill, especially for some difficult materials. Ultrasonic vibration assisted drilling belongs to one of the vibration drilling techniques, that is, the high frequency vibration of more than 15 kHz is applied to the twist drill during the drilling process, and the periodic vibration of the bit improves the working condition of the cutting edge. To some extent, it can solve the problem of hole making of difficult-machined materials. This paper introduces the classification, technical characteristics and system composition of ultrasonic vibration assisted drilling technology. Based on the research of dynamics, vibration chip breaking theory, cutting force, precision and machining quality, the paper introduces the research of ultrasonic vibration assisted drilling technology. The research progress of ultrasonic vibration assisted drilling theory and technology is discussed in six aspects of the application of new materials and ultrasonic vibration drilling device. Based on the development status of ultrasonic vibration assisted drilling technology, combined with the requirements of the drilling technology of difficult machining materials in aerospace and other fields, the theoretical research, the development of ultrasonic vibration system and the study of new material technology are discussed. The development of special ultrasonic assisted drilling machine tool and the standard formulation of ultrasonic vibration aided machining standard are pointed out in this paper. The existing problems in research and application are pointed out and the development trend in the future is prospected.
