激光振动辅助切削Ti6Al4V加工机理的有限元仿真
Mechanism of Laser-vibration Assisted Machining of Ti6Al4V via Finite Element Method
摘要
Abstract
Ti6Al4V Titanium alloy is a typical difficult-to-machine metal.Improving its machinability and reducing processing difficulty hold significant research value.A two-dimensional plane strain finite element simulation model for machining processes of Ti6Al4V was established,covering various machining methods including laser-vibration-assisted machining,vibration-assisted machining,laser-assisted machining,and conventional machining.By comparing and analyzing key variables in the machining,such as temperature field,equivalent plastic strain,degree of chip serration,and cutting force,its machining mechanism was investigated.Comparing with other machining methods,the results of laser-vibration-assisted machining show that appropriate laser power and increasing vibration frequency can reduce the tool-workpiece temperature;the average equivalent plastic strain in the shear band decreases significantly;the degree of chip serration decreases with increasing laser power,and increases to some extent with higher frequency and amplitude;the cutting force is significantly reduced,and increasing frequency and amplitude can further decrease the cutting force.关键词
