Research on Blade Error Variable Margin Compensation Based on Online Measurement
Blade is an important component in the aircraft engine,and the machining and molding quality of the blade has a great impact on the safety and efficiency of the engine when it actually works.In this paper,base on the online meas-urement results,the overall error value of the blade after machining is obtained,and the variable margin compensation is de-signed according to the error results,and the blade margin is reconstructed through NURBS curve compensation to compen-sate for the machining error.The results of machining before and after compensation are analyzed through experimental com-parative study.The results show that the accuracy of the machined parts can be effectively improved after compensation.Un-der the experimental parameters,the maximum contour error without compensation is 0.057mm;after compensation,the contour error becomes 0.024mm,and the optimized machining result meets the accuracy requirements,which can effectively meet the requirements of practical use.
