Abstract :
The characteristics of accuracy control of large-scale airfoil-wainscot parts are analyzed. The accuracy of airfoil-wainscot is controlled by its rib curves, and the rib curves are straight lines whether after processing or before on the direction of face projection. The method of compensating the radius of measuring probe is presented also based on measuring data from 1D scanning probe. Aiming at the inspection requirement of the measured part and the characteristics of rib curves, the algorithms of curve matching and error analysis are proposed. The experimental results show that the proposed methods can meet the accuracy requirement of online inspection of airfoil-wainscot parts.
