| Abstract: | The 3-TPT parallel machine tool developed by Northeastern University was investigated. Based on a structure analysis, the 3-TPT parallel mechanism shows the translation as its kinematic feature. The position equation is given as well as both the direct and inverse kinematic solutions to it. How the telescopic rod of driving link moves due to the movable platform which is moving in accordance to a planned movement was discussed and proposed. The planned trajectory was verified via a kinematic simulation done for the virtual prototype. The results showed that the way proposed to plan the trajectory is simple to implement with favorable applicability. |
