Curvature-adaptive Multi-jet Freeform Polishing System for Precision Manufacturing

Polishing freeform surfaces is a great engineering challenge, as the curvature effect always results in considerable residual errors. Our novel technology enables jet array customization and real-time control and adjustment of the fluid pressure of each jet according to surface curvatures, in order to compensate residual errors induced by the curvature effect. Compared to conventional single jet polishing, it tremendously enhances the efficiency and accuracy of freeform surface polishing. It has been developed into a portable apparatus which can be integrated into various types of machines such as polishing machines, robotic arms and 3D printing machines.
