Study on Deformation Prediction and Cutting Parameters Optimization for Turning of Thin-walled Gear Spoke in Aerospace
To fulfill the lightweight requirements of helicopter transmission systems,transmission gears as a critical component of helicopters,possess the noticeable characteristic of thin walls,which presents challenges in terms of severe deformation and the assurance of dimensional precision during the machining process.This article focuses on the study of thin-walled gear spoke plate made from high-strength medium alloy carburized steel.Using the ABAQUS finite element analysis software,a simulation study on the cutting process was conducted.By establishing a three-dimensional dynamic cutting simulation model,the relationship between the cutting forces and the cutting parameters on the parts in the machining was analyzed.Static simulation methods were used to analyze the influence of the superposition of cutting force and clamping force on the processing deformation of thin-walled spoke.Then range analysis was used to examine the simulation results.Finally,the experimental validation of the simulation results was carried out.The results indicate that in the static analysis of gear thin-walled spoke plate machining deformation,the axial deformation of the gear spoke plate is most significant,and the radial deformation is most prominent at the hub.Range analysis reveals that the optimal cutting parameters are the cutting speed of 150 m/min,the feed rate of 0.06 mm/r,and the cutting depth of 1.8 mm,with the prediction error for the maximum deformation of below 10%.
