航空难加工材料螺旋铣孔专用刀具设计及开发

摘要

For aircraft use difficult to machining titanium alloy and composite materials , spiral hole milling technology the certain advantages , but due to the operation in the process of using traditional milling cutter , so there are still many problems and need to for aircraft assembly of spiral hole milling special tool for improvement . The aviation difficult processing special material spiral hole milling knife design and application research , through the analysis of the process of spiral hole milling cutter movement characteristics and traditional milling cutters in spiral hole milling processing problems , and design for modern processing materials of drilling tool , so as to improve the drilling tool utilization efficiency and create conditions .%对于飞机上用到的难加工的钛合金以及复合材料，螺旋铣孔技术表现出了一定优势，但因操作过程中多使用传统的立铣刀，所以仍存在不少问题，需要对飞机装配的螺旋铣孔专用刀具进行改良。本文将对航空难加工材料螺旋铣孔专用刀的设计与应用进行研究，通过分析螺旋铣孔过程中刀具的运动特点以及传统立铣刀在螺旋铣孔加工中出现的问题，进而设计出适合现代加工材料的钻孔刀具，从而为提高钻孔刀具的利用效率创造条件。
