Kinematics of a 3-dof (degree of freedom) parallel machine tool with large workspace was analyzed. The workspace volume and surface and boundary posture angles of the 3-dof parallel machine tool are relatively large. Firstly, three dimensional simulation manipulator of the 3-dof parallel machine tool was constructed, and its joint distribution was described. Secondly, kinematic models of the 3-dof parallel machine tool were fixed on, including displacement analysis, velocity analysis, and acceleration analysis. Finally, the kinematic models of the machine tool were verified by a numerical example. The study result has an important significance to the application of the parallel machine tool.
