激光加热辅助车削高温合金薄壁件变形仿真及试验研究
Simulation and Experimental Study on Deformation of Thin-walled Superalloy Parts in Laser-assisted Turning
摘要
Abstract
As an important part of aero-engine,casing is a typical thin-walled part.Its large size,thin wall and low rigidity make it prone to workpiece deformation and tool chatter in the machining process,resulting in substandard machining accuracy and poor surface quality.In this paper,models of conventional turning and laser-assisted turning of superalloys were established by the software ABAQUS,and the accuracies of the models were verified by tests.The maximum error of the models is 10.1%,the minimum error is 5.5%and the average error is 7.8%,which is within an acceptable range.Then,models of conventional turning and laser-assisted turning of thin-walled parts were developed to study the effect of laser-assisted turning on the deformation of thin-walled parts.The results of the study show that compared with conventional turning,the cutting forces of laser-assisted turning decreased by 20.2%,19.8%and 15.2%respectively when the laser irradiation temperature reached 650°C or more.The machining deformation of thin-walled parts can be reduced in laser-assisted turning.Compared with conventional turning,the machining deformation of thin-walled parts in laser-assisted turning is reduced by 13.5%,11.2%and 10.4%respectively.关键词
