The kinematics character of the 3 TPT in parallel mechanism of virtual axis machine was analyzed. The kinematics model of virtual axis machine was given. Based on the model,the explicit kinematics reverse formula and forward formula were obtained together. Using the ActiveX operation mechanism provided by MDT and object oriented based method,the motion simulation method of 3 TPT virtual axis machine was studied and the specific procedure was given. The procedure is programmed in Visual Basic environment. By simulation analysis this kind of 3 TPT in parallel mechanism proves to be simple and has explicit forward & reverse kinematics formula,by which real time motion control can be realized easily.
