Notes:
This paper develops a novel five DOF hybrid polishing kinematics machine tool in orderto obtain more stable machining result in the elastic polishing on the free-form surfaces. Becausethe machine tool is a complex multi-body system that comprises many close-loop structures,jointing clearance becomes the important influence factor to its moving stability. The unified rigidmulti-body and flexible multi-body dynamics equation of for the parallel mechanism of hybridpolishing kinematics machine tool is respectively built, which considers the influence of joint withclearance and applies the kinematics model of Newton second state. The result of analysis showsthat the moving stability of the hybrid polishing kinematics machine tool is reduced due to theexisting jointing clearance. However, the interior flexibility of the mechanism can reduce the shockeffect of collision in the part of motion pair. It can improve the working stability of mechanism
