Abstract： In order to optimize the gasbag polishing effect on mould curved surfaces，polishing experiments on mould curved surfaces with different radius of curvature were made on the 6-DOF gasbag polishing experiment platform. The contact size， the contact force and polishing quality of the contact area and the polishing effect were studied. On this basis，a method was presented that through the adjustment of pressure amount and inflation pressure of the gasbag，the contact size and contact force can be adjusted and the polishing effect on the mould curved surface can be optimized. The two-dimensional surface of mould polishing was tested using the above method. The experimental results show that after optimizing the contact characteristics，polishing quality on different radius of curvature is on the same level and the polishing effects can be optimized.
