随着航空制造业的发展,对航空发动机关键零部件的质量提出更高的要求,由于其材料大多为难加工材料,并具有复杂结构特征,给加工制造带来了很大的困难。如何能高效、高质量地加工出这些复杂零部件是亟需解决的难题,而盘铣加工技术及其刀具应用则是解决这一难题的有效途径之一。本文首先对航空发动机部件整体叶盘的材料特性进行分析;然后,进行整体叶盘盘铣加工技术的探讨,对其可行性制造方法进行比较,明确高效盘铣加工技术在整体叶盘的加工中具有显著优势;其次,在对盘铣切削特点及其加工方式进行分析基础上,还就盘铣刀的应用及其失效形式进行探讨;进而,从盘铣刀具材料的选用、几何特征的特殊设计、刀片新型槽型开发等方面实现对刀具结构的优化设计。以上分析探讨将为解决整体叶盘的高效切削问题及航空航天领域核心零部件国产化提供参考。
With the development of the aviation manufacturing industry, the quality of the key components of aeroengines is put forward higher requirements. Since most of the materials are difficult to machine materials and have complicated structural characteristics, it brings great difficulties to the manufacturing. How to process these complex components efficiently and with high quality is an urgent problem to be solved. Disk milling technology and its tool application are one of the effective ways to solve this problem. In this paper, we first analyze the material properties of the whole leaf disk of aeroengine components. Then, we discuss the disk leaf milling processing technology and compare the feasibility of the manufacturing method. It is clear that the efficient disk milling technology in the processing of the leaf disk And has the significant advantage; Secondly, based on the analysis of the characteristics of milling and milling and its processing methods, the paper also discusses the application of the disk milling cutter and its failure forms; Furthermore, from the selection of the material of the milling cutter, the special geometric features Design, new slotted blade development and other aspects of the optimal design of the tool structure. The above analysis will provide a reference for solving the problem of efficient cutting of the leaf disc and localization of the core components in the aerospace field.
