Abstract: In practical machining processes,the dimensional accuracy of thin-walled workpiece was significantly afected by multiple factors including cutting forces, forced vibrations,chatter phenomena,geometric characteristics of workpiece and material properties,rendering deformation prediction and control particularly challnging.A multi-source information fusion method for deformation error prediction in thin-walled workpiece miling processes was developed. Machining parameters,vibration signals,and other relevant data were integrated to establish a deformation error prediction model through Stacking ensemble learning methodology, with comprehensive experimental validation performed. Comparative analyses reveal that the constructed model demonstrates superior robustness, higher accuracy,and enhanced practicality when compared with conventional data-driven prediction methods.

薄壁零件廣泛應(yīng)用于電子信息、航空航天等領(lǐng)域,是一類非常重要的典型零部件,但其剛度較低,在銑削加工過程中受切削力、強(qiáng)迫振動(dòng)、顫振等多方面因素影響極易出現(xiàn)較大的變形誤差,導(dǎo)致最終產(chǎn)品加工質(zhì)量下降。(剩余12550字)
