Large twisted blade Measuring

Large twisted blade Measuring

Aiming at the inspection of large twisted engine blades which are composed of complex thin structures, variable curvature, and single-dovetail tenon, MTI has developed a special profile measurement method by combining the rotary continuous scanning probe of 3-axis measurement machine (hardware) and the coordinate system (software) set up by the best fitting method. An innovative method that scans the blade tips by auxiliary coordinate system was accordingly adopted. This effectively eliminates the problems of tip-probe resonance phenomenon, variable geometric tolerance, and reduction of stiffness of blade tips caused by increasing scanning height. This method greatly improves the measurement accuracy of large twisted blade and is one of the significant measuring methods for engine structures.
