Depth of Cut Control for Thin-walled Parts in Robotic Milling Based on FLADRC

Abstract： Weakly rigid large thin-walled parts had large deformations and vibrations during ro botic thinning machining，which led toa degradation of the surface quality of the workpieces and difficulties in ensuring the accuracy of the remaining wall thickness.To this end，a VCM-driven follower support head was used for vibration and deformation suppression，and a FLADRC based control strategy was proposed for depth of cut of robotic milling thin-walled parts. In order to verify the effectiveness of the control strategy，the system control models were firstly established based on the MATLAB/Simulink simulation and experimental platform，and the simulation analysis was carried out， then experimental verification was carried out on the thin-walled parts robotic milling experiment platform.Both of the simulation and experimental results show that the depth-of-cut control strategy based on the folower support head may significantly suppress the vibrations and deformations during the machining processes of thin-walled parts and efectively ensure the accuracy of the remaining wall thickness. In addition，compared with the traditional fuzzy PID control，the FLADRC has a better control effectiveness and exhibits higher robustness in the presence of external disturbances.
