Abstract

The invention belongs to the technical field of shell machining, and discloses a method for machining multiple holes in a large-sized global shell. The method includes the steps that a three-dimensional space coordinate system of the large-sized global shell is established, and three-dimensional data of the large-sized global shell are measured; position coordinates of a machining system in the three-dimensional space coordinate system are determined; a machining theoretical model of the large-sized global shell is compared with the three-dimensional data of the large-sized global shell to obtain machining coordinates based on the three-dimensional space coordinate system; the machining system is moved, and the holes are formed in the large-sized global shell based on the machining coordinates; and the steps are repeatedly executed, and the next holes are machined. The method for machining the multiple holes in the large-sized global shell is specially used for large-diameter specifications and is high in precision requirement.

Description

technical field [0001] The invention relates to the technical field of shell processing, in particular to a method and system for processing holes in a large spherical shell. Background technique [0002] Affected by the processing stress and the change in self-weight after material removal, the perforation of the spherical shell will lead to large deformation of the spherical shell, offset of the center of the ball, and difficult processing. [0003] In the prior art, the hole machining of the spherical shell is generally realized by the existing large-scale five-axis machining center. The limitation of this method is too strong. There is a lack of effective processing methods for high-precision perforated spherical shell processing in the range of machine tools. Contents of the invention [0004] The invention provides a method and system for processing holes in a large-scale spherical shell, which solves the technical problem in the prior art that there is a lack of hi...
