盘形可转位大模数齿轮铣刀强度有限元分析

通过分析影响盘形可转位大模数齿轮铣刀切削力的几个因素,确定每齿进给量变化是影响切削力的主要因素。以此为基础,介绍了齿轮铣刀的强度有限元分析的方法。利用有限元方法分析齿轮铣刀的刀体强度,验证了铣刀的设计安全性,为铣刀的优化设计提供了参考。

Finite Element Analysis of Disc Indexable Big Modulus Gear Milling Cutter

In this paper, several influence factors of disc indexable big module gear milling cutter on cutting force was analysed. It was determined that feed per tooth change is the main factor affecting cutting force, on this basis, the strength finite element analysis method of gear milling cutter was introduced. The finite element method was used to analyse gear milling cutter body strength, which can verify the cutter design safety and provide the reference to optimize the design.
