Machining and sorting method and system for hole characteristics of rotary cabin

The invention provides a machining and sorting method and system for hole characteristics of a rotary cabin, and the method comprises the following steps: S1, constructing a projection plane for a rotary shaft of a cabin part, and building a rectangular coordinate system; S2, determining a projection point of the hole feature on the projection surface, and calculating an included angle between the projection point and a coordinate axis; S3, establishing a hole group set according to the included angle, and establishing a mapping relation between the angle and a hole group; S4, on the basis of the one-way principle, the machining sequence of different hole groups being subjected to arrangement optimization; and S5, arranging the hole feature machining sequence in the arranged hole group. According to the method, the projection plane is constructed to divide and integrate the hole features according to the positions of the hole features on the projection plane, and then the hole group set used for sorting is co
