Research on groove optimization for milling insert based on finite element analysis

摘要

This article takes the waved-edge milling insert (the rake face is curve plane) developed by Harbin University of Science and Technology as an example, based on the force density function and heat density function, we have the finite element analysis (FEA) on the stress fields and temperature fields of different cutting parameters, and have fuzzy synthetical judgement on them with fuzzy mathematic theory. We build the quantitative function relation between the fuzzy synthetical judgement results and cutting parameters, so to have groove optimization design and provide the groove optimization process. All these studies provide the theoretic basis for the groove exploitation and the cutter disrepair which is the key problem in the automatiz ation production.
