Research on the Dynamic Modeling and Simulation of Milling Robot

The dynamic conditions of milling robot in milling process have great influence on the movement and stability of the mechanism.This paper takes the 6-dof milling machining robot as research object.The three-dimensional model of the robot is established using the three-dimensional modeling software Creo,which is used to obtain the inertial parameters of the robot dynamic modeling.The dynamic analysis of the industrial milling robot is performed by using Newton-Euler recursive method.And in the MATLAB environment,the established dynamic equations are programmed,then,the robot movement process is calculated and analysed.And then,ADAMS software is used to conduct the dynamic simulation analysis of the established three-dimensional model,and the results of MATLAB calculation and ADAMS simulation analysis show that the established dynamic equation is correct.The certain theoretical basis is provided for researching on the dynamic condition of milling robot in the milling process.
