Prediction Method of Milling Tool Life Based on Analysis of Modal Characterization
During the machining process of Ti-6Al-4V titanium alloy,the machining vibration is prone to occur,which can accelerate tool wear and reduce tool life.In this study,based on the Taylor tool life exten-sion model,a milling tool life prediction model considering the modal parameters of the thin-walled machi-ning system is proposed.First,modal measurement experiments and milling tool wear tests are conducted to obtain the system's modal parameters and tool wear values.Then,the milling tool life prediction model is established using the modal parameters and wear values,and the impact of various parameters on tool life in milling is compared and analyzed.Finally,The accuracy and reliability of the model were validated through cutting experiments using titanium alloy Ti-6Al-4V.The results show that the milling tool life prediction method based on the analysis of machining chatter characteristics can more accurately predict tool life in the machining of thin-walled components,providing theoretical guidance and practical references for further im-proving tool life and machining quality.
