一种新的铣刀刀齿等效直径确定方法
A New Method for Determining Equivalent Diameters of Milling Cutters
摘要
Abstract
In order to determine the equivalent diameters of milling cutters,an equivalent model of milling cutters was established,which was divided into tool holder and cutter teeth,then based on structural analysis and results calculated theoretically,the target function of optimizing cutter teeth e-quivalent diameters was established,and cutter tooth's equivalent diameters were determined using genetic algorithm.Taking several two fluted milling cutters,three fluted ones and four fluted ones with different parameters as the study obj ects,adopting the proposed method to determine their teeth's equivalent diameters,which were used to calculate their tool point frequency response func-tions respectively,and comparing the tool point frequency response functions calculated by the pro-posed method with ones calculated by equivalent mass method and experimental results.It is shown that the proposed method has higher calculation accuracy and better adaptation.关键词
