Advances in Robot-Assisted Gas Bag Polishing for Precision Manufacturing

Robot-assisted gas bag polishing has emerged as a promising flexible polishing technology for precision manufacturing, particularly for complex free-form surfaces. Its compliant polishing mechanism enables uniform contact pressure and improved surface quality compared with conventional rigid polishing methods. Recent developments, including magnetorheological and magnetic abrasive gas bag polishing, have significantly enhanced material removal efficiency, polishing stability, and surface finish. Although considerable progress has been achieved, maintaining accurate contact force and pressure remains a critical challenge for achieving consistent polishing performance on complex geometries. Future advancements are expected to focus on intelligent force control, AI-based process optimization, digital twin technology, machine vision, and real-time surface roughness prediction. The integration of these technologies with smart robotic systems will enable autonomous, adaptive, and highly efficient polishing processes, making robot-assisted gas bag polishing a key technology for next-generation precision manufacturing applications.
