As a new hole-making technology, helical milling has advantages of stable machining process, small cutting forces and the use of a single tool to process various diameter hole etc., and it is widely used in machinery manufactory industry, in which the aircraft assembly is a typical representative. With helical milling as the research object, the advan- tages of helical milling over traditional drilling are investigated. The research progress of helical milling technology is expounded from the aspects of kinematics, dynamics and virtual prototype design, and its prospect is presented.作为一种新型制孔方式，螺旋铣孔工艺具有切削过程平稳、切削力小及使用单一刀具可加工多种直径孔等诸多优点，被广泛应用于以飞机装配为代表的机械制造业。以螺旋铣孔工艺为研究对象，分析其相对于传统钻孔工艺的优点，从运动学、动力学和虚拟样机设计等角度，阐述了螺旋铣孔技术的研究进展，并展望了其研究方向。
