Abstract
Thin walled parts are widely used in high-end manufacturing fields such as aerospace and automotive,but their milling processing faces many challenges due to their structural characteristics and high-precision requirements.This study focuses on the optimization of milling process parameters for thin-walled parts,deeply analyzes the machining difficulties,and provides a detailed analysis of the impact mechanism of key parameters such as spindle speed,feed rate per tooth,axial and radial cutting depth on machining.By comprehensively utilizing experimental design,simulation technology,and intelligent algorithms to explore optimization strategies,the optimized process parameters were verified through the example of 7075-T651 aluminum alloy thin-walled parts in the aerospace field.The machining quality was significantly improved with dimensional accuracy stabilized within±0.03mm,surface roughness reaching Ra1.2 μ m,scrap rate reduced to below 5%,single piece machining time shortened to 2.5 hours,and machining efficiency greatly improved.This research achievement provides strong support for precision machining of thin-walled parts and has significant implications for promoting the development of high-end manufacturing in multiple fields.关键词
