Abstract: Drilling all kinds of connecting holes is one of the major process in aircraft assembly. Because difficult-to-cut materials are using more and more and hole diameter is becoming bigger and bigger in the new large aircraft, hole-making is more difficult to carry out, as a result, conventional drilling process is failing to meet the requirement gradually. Helical milling is a new hole-making process for aircraft assembly, in which the cutting tool rotates on a helical path and generates the borehole. Due to the changed cutting principle, helical milling has more advantages compared with conventional drilling process, such as high quality, high efficiency, low tool cost and wide applicability. For these reasons, helical milling becomes one of the research focuses currently. Firstly, the fundamental and advantages of helical milling are expounded. Secondly, the research status of helical milling is summarized from the machining mechanism and special equipment. Finally, the development trend of helical milling for aircraft assembly is analyzed.
