Self-adaptive machining method for deformed plane of part

The invention relates to the technical field of machine manufacturing, in particular to a self-adaptive machining method for a deformed plane of a part, which comprises the following steps: selecting a plane on the other side relative to a reference plane to be parallel to any coordinate plane in a three-dimensional coordinate system of a numerical control machine tool, and enabling the reference plane to be parallel to at least one coordinate axis in the coordinate plane; deformation points, abutting against the multi-flat-plate mold, in the deformed to-be-machined plane are selected, and a first plane is constructed to serve as a machining plane of the machine tool spindle; four mark points are selected on the top plane of the flat mold, and the distance between the mark points and the reference plane where the part plane is located before deformation is obtained and serves as the deformation of the mark points; and based on the distance and deformation of the mark point on the entity plane, the rotation an
