Research on Path Planning Method for On-Line Measurement of Blisk

Abstract:

The blisk is an important component of aviation engine and its level of machining and measurement will directly affect the application properties of the engine. This paper investigates the on-line measurement of single blade of the blisk. The section lines and the points to be measured are determined by using the empirical formula based on B-spline theory and feature point extraction algorithm. The probe-blade interference problem is solved by dividing the measurement area into different sectors and the posture angle of the probe in different inference-free sector domain is determined. The CATIA simulation is conducted to validate the correctness of the path planning algorithm for measurement. The measuring path planning plays an important role in improving the efficiency and reducing the cost of measurement.
