Advances in Robot-Assisted Abrasive Polishing for Precision Manufacturing

Robot-assisted abrasive polishing is a promising surface-finishing technology for precision manufacturing because it combines robotic flexibility and repeatability with controlled abrasive material removal. The review shows that robotic polishing can reduce operator dependency, improve surface consistency, and provide better control when finishing complex and curved geometries. Different polishing technologies offer different capabilities depending on workpiece material, geometry, required surface finish, and production requirements. Robot-assisted polishing provides a flexible approach for automated finishing and is particularly suitable for precision components and complex surfaces. The overall polishing performance is influenced by process parameters, tool wear, abrasive degradation, robot stiffness, surface curvature, contact force, and tool-workpiece interaction. Proper control of these factors is essential for achieving uniform material removal and improved surface quality. Despite its advantages, wider industrial implementation requires improved control of force, tool condition, and surface quality. Future research should focus on adaptive force control, machine-vision-assisted inspection, real-time process monitoring, digital-twin simulation, and intelligent optimization. Integration with Industry 4.0 technologies can support closed-loop and autonomous polishing systems.   Overall, robot-assisted abrasive polishing has considerable potential to provide repeatable, flexible, and high-quality surface finishing for precision manufacturing. Continued development of sensing, adaptive control, process modelling, and intelligent automation will be important for achieving more efficient and autonomous polishing operations.
