基于应力场分析的铣刀片冲击破损目标函数研究

以哈尔滨理工大学开发的波形刃(前刀面为波形曲面)铣刀片为例,以最小冲击破损为目标,进行铣刀片槽型优化目标函数的研究。在已建立的三维复杂槽型铣刀片受力密度函数的基础上,进行铣刀片不同切削参数下的应力场有限元分析,应用模糊数学理论对应力场进行模糊综合评判,建立应力场模糊评判结果与冲击破损切削参数之间的目标函数关系,从而进行目标函数的槽型优化设计。本研究为铣刀片的开发及解决自动化生产中刀具破损这一关键技术问题打下理论基础。

Study on Object Function of Milling Insert Impact Disrepair Based on Stress Field Analysis

This article takes the waved-edge milling insert（the curve rake plane） developed by Harbin University of Science and Technology as an example,as the goal of minimal impact disrepair,the optimization object function of the milling insert grooves is studied.Based on the force density function of the 3D complex groove milling insert,we have the finite element analysis on the stress field of different cutting parameters,and have fuzzy comprehensive judgement on the stress field with fuzzy mathematic theory.We build the object function relation between the fuzzy judgement result and cutting parameters of impact disrepair,so to have optimization groove design.All these studies provide the theoretic basis for the groove development and the cutter disrepair which is the key problem in the automatization production and groove optimization.
