Aircraft bearing component is the key bearing component of large passenger aircraft and fighter aircraft

which is prone to dimensional deformation during the forming process. However

the current caliper

plug gauge testing method has some problems

such as low efficiency and poor consistency of results. To this end

this paper intends to solve above problems by three-dimensional measurement technology. This paper proposes a crude registration method based on standard spherical characteristics and a fine registration method based on the shaft hole key characteristics. Meanwhile

studies the size/shade error systematic automatic calculation method of the aircraft support member

and conducts digital detection experiment of a model aircraft holder member based on autonomous software modules. The results show that the proposed method has significantly improved the detection efficiency and stability compared with the manual detection method.
