Digital Twin for Robotic Multi-Axis Additive Manufacturing and Precise Measurement

Original language description

This function sample evaluates the performance and advancements achieved in the past year, specifically in the field of multi-axis additive manufacturing with an industrial robot coupled with a rotary-tilt positioner. Our system, utilizing a filament extruder mounted on the robot's end-tip, has demonstrated significant improvements in the geometric complexity of objects produced and precision in printing parameters. The integration of a laser tracker has been pivotal in this progress. It played three essential roles: enhancing machine calibration, correcting positional errors through online feedback, and precisely measuring calibration artifacts. This advancement has enabled our operators to more effectively calibrate the robot's workspace, conduct extrusion calibration, monitor the robot's accuracy during production, and analyze calibration artifacts for deeper insights into the additive manufacturing process. A key aspect of this year's progress involved aligning the real-world conditions of our equipment with their virtual counterparts. We created a digital twin of the workspace and automated the code preparation process for the robot, thus eliminating the need for specialized personnel. This automation was facilitated by a custom-developed module. We also focused on experimentally identifying the optimal printing process parameters by producing samples under various settings. These results were fed into our digital twin software, enhancing its accuracy and relevance. Our experimental setup, a workstation designed for robotic multi-axis additive manufacturing, has been instrumental in validating our methodologies. The effectiveness of our approach was confirmed by producing and analyzing four parts through robotic multi-axis additive manufacturing. These parts underwent laser scanning, and their dimensional deviations were meticulously evaluated to assess our system's precision and efficiency.
