Research on Inverse Dynamics and Trajectory Planning for the 3-PTT Parallel Machine Tool

In this paper, dynamics modeling of the 3-PTT parallel machine tool is carried out by the Lagrange method. The cycloid curve is adopted in the planning of the trajectory. Combined with a practical example, the computer simulation is carried out. It provides a theoretical basis for the control of the machine tool. The work will provide help for the control and structural optimization design of the parallel machine tool.
