Digital twin-driven staged error prediction and compensation framework for the whole process of robotic machining

Contribution

The main contributions of this paper can be summarized as follows:

1. For the differentiated performance of the error in the whole process of robot machining, an error staging strategy is established;
2. The error perception and compensation units for each stage are established based on the characteristics of the error in the respective stage and the equipment characteristics of the system;
3. A digital twin system embedded with a stage-by-stage error sensing and compensation function block is developed to realize system-level control of robot machining error for the characteristics of error variation in the whole process of robot machining.
