In the field of aeronautical aircraft, no matter military aircraft or civil aircraft, a large number of special-shaped forgings and castings with hole characteristics need to be machined to ensure the dimensional accuracy. Such parts are characterized by a relatively complex structure, generally requiring machining of each face. Therefore, the processing procedure is long, the types of machine tools are more, and the processing period and the cost are high. How to realize multi-surface and multi-process machining on one machine tool is a poor choice for solving the problems. This requires that the arrangement of the locators, the compactors, etc. used in the associated machining jig does not occupy the feed path, even if the machining surface is completely open. The positioning and pressing of the clamp design are required to be started from internal structural elements of the product, the most common hole elements are used, and the problems can be solved by fully utilizing the positioning and tensioning of the holes. The present invention has been made in view of the above technical background.
