| Abstract: | A novel orthogonal 5-DOF parallel machine tool is proposed,and the kinematics analysis of the 5-DOF parallel machine tool is presented.First of all,the kinematics and Jacobian matrix for the 5-DOF parallel machine tool were derived analytically.Then the kinematics transmission index and global kinematics transmission index were defined.Finally the kinematics atlases were analyzed by using the physical model technique.The results can provide theoretical basis for the applications of the 5-DOF parallel machin... |
