Study on Measuring Flange Hole of Aviation Conduit

摘要

This research is based on the scientific special project "research and application validation of key technologies for intelligent production line of aircraft ducts". This project number is MJ-2016-G-64. This paper is aimed at the small holes on the flange face of the aviation conduit, two different measuring methods are discussed for measuring the aperture and center coordinates, that is. the accuracy and repeatability of projection method and cylindrical fitting method. The triangular laser scanning probe used in the system is more convenient for data acquisition and less affected by light occlusion. With this system, high precision, high efficiency and high repeatability can be selected.
