Abstract
The application provides a dynamic error compensation and control method and system in multi-axis linkage tool machining, relates to the technical field of numerical control machining, and comprises the following steps: acquiring real-time machining data, performing error decomposition, constructing an error transmission tensor field to extract a dynamic coupling relationship, constructing and integrating an error compensation vector field in a tool movement space based on the relationship and precision constraints, generating each axis compensation track to adjust a driving instruction, and correcting the error model by using feedback information after the compensation is implemented, so that online compensation and control of the dynamic coupling error are realized, and the machining precision is improved.
