Abstract:
To solve the problems of current probes for blade profile metrology, such as poor flexibility, low accuracy and efficiency, a form-free high-precision probe system is proposed in this study. First, a novel and form-free optical probe system is developed based on the concept of 'Synchronization of Planning and Measurement'. Secondly, the operational principle, the theoretical model and key technologies of the probe system are analyzed in detail. Finally, experimental evaluations are carried out to verify the feasibility and accuracy of the probe technical scheme. Experimental results show that the path planning and the blade profile data collection are achieved simultaneously without theoretical model data and attitude fine-tuning of the blade. The measurement is completed in the positions near the reference distance of the sensor. Thus, the inclination error is effectively limited and the measurement error is reduced to be less than 10 μm. The designed probe system has the advantages of simple algorithm, high precision and form-free, which has a good application prospect in the field of free-form surface measurement. © 2018, Science Press.
