Research on impact of geometric errors of heavy CNC machine tools on machining errors of wind turbine bearing raceways
2024
Overview
To address the issue of machining errors in large rotary workpieces caused by geometric errors of heavy vertical lathes, this study focuses on measuring and modeling geometric errors of such lathes. By identifying the specific geometric errors that impact the machining accuracy of heavy vertical lathes and extracting the crucial ones, the study investigates the contribution degree of the error of geometric errors during the machining process of the wind turbine bearing raceways. The study combines the geometric error fitting function to predict the position error and profile error of feature points on the bearing raceway cross-sectional curve. It also performs an inverse evaluation of the contact angle of the wind turbine bearing raceways. The study aims to clarify the influence of crucial geometric errors in heavy vertical lathes on machining errors during the machining process of wind turbine bearings. The findings provide theoretical and practical guidance for the subsequent design and manufacture of heavy machine tools and the vertical turning process of large rotary workpieces.
