Abstract

The invention discloses a complex component machining residual wall thickness self-adaptive compensation method based on coordinate origin translation, and belongs to the technical field of measurement-machining integration. According to the method, on an open type numerical control platform, wall thickness data of a component is measured through an ultrasonic thickness measuring device, a machining target curved surface related to the residual wall thickness is reestablished, inclusiveness analysis is completed, coordinate origin translation amount calculation is conducted, and machining compensation is completed through machining code origin correction. According to the method, the defects of an existing residual wall thickness compensation method are overcome, the machining requirement that the residual wall thickness and the profile tolerance of the complex component are restrained at the same time is met, the machining precision is improved, the labor intensity is reduced, and self-adaptive compensation of the machining residual wall thickness of the complex component is achieved.

Description

technical field [0001] The invention belongs to the technical field of measurement-processing integration, and in particular relates to an adaptive compensation method for remaining wall thickness of complex component processing based on coordinate origin translation. Background technique [0002] Complex components are typical parts of major equipment in aerospace and other fields, such as cabin components, etc. The remaining wall thickness of the processed parts must meet the processing requirements of equal wall thickness or variable wall thickness according to a certain rule, and the remaining wall thickness is often The core requirements for the processing of such components. However, in the actual machining process, some complex components are affected by factors such as structure, and after semi-finishing, only the outer surface can be machined. The outer surface is an ideal shape approaching the design model; while the inner surface of the workpiece is a cast shape. ...
