Abstract: A new 3-legged parallel root machine tool was designed. This machine tool can machine vertically as well as horizontally when the mill head is rotated some angle. The structure and characteristic of the machine tool were introduced. The kinematics of the machine tool was studied. The kinematics equations of Corresponding position, velocity, and acceleration were deduced by analyzing the parallel stopper mechanism. Formula of the Jacobian matrix was obtained. The kinematic equations of this machine tool are very simple and easy to solve. The real-time control of the machine tool is easy. This machine tool can be applied to the wood, soft metal or nonmetal machining.
