Inclined hole multi-reference location degree detection method

The invention belongs to the technical field of aviation machinery, and discloses an inclined hole multi-reference location degree detection method, which comprises the following steps: establishing a three-dimensional mathematical model of a structure where an inclined hole is located, generating a corresponding inclined hole theoretical value, performing regular offset on the inclined hole theoretical value to obtain a correspondingly generated location degree deviation, and forming a series of data of each orientation. Carrying out statistical analysis on the series of data of each orientation to form a position degree deviation contribution rate calculation formula of different orientations; and synthesizing the position degree deviation contribution rate calculation formulas of different directions to obtain a comprehensive position degree. From the perspective of processing, the synthetic location degree is analyzed, the main source of location degree deviation is found, a three-dimensional mathematical
