Abstract

Blade is one of the core components of the aero-engine, which requires a high degree of geometric dimension precision, so strict geometric shape detection and evaluation is very necessary to guarantee blade machining quality. Twist error is one of the important parameters of blade quality evaluation, which directly affects the evaluation results. In this paper, two kinds of methods are used to calculate the twist error of blade at first, and the calculation method based on the definition of twist degree is studied emphatically. Finally, the twist error extraction experiment was carried out with the actual measurement data of blade, and the validity of the method was verified by comparison.
