N2 - Mechanical polishing with abrasive slurry is a kind of finishing process that can reduce the surface roughness and improve the form accuracy effectively. In this chapter, the development of a serial-parallel machine for precision polishing of freefrom surface is presented. The topological structure of the machine is a six degrees-of-freedom (DOF) hybrid serial-parallel mechanism, including a three-DOF parallel mechanism, a two-DOF serial mechanism, and a functional extension limb providing a redundant DOF. The main features of the polishing machine are reflected in two aspects including the following: (1) the machine inherits the advantages of both serial mechanism and parallel mechanism, and (2) the rotation and translation motions between the polishing tool and the workpiece are decoupled. In this chapter, a systematic kinematics and stiffness analysis of the hybrid serial-parallel mechanism are performed. Afterward, the development of the polishing machine is explained. Finally, some preliminary experiments have been conducted on a saddle surface which aim to evaluate the performance and demonstrate the capability of the machine.
