| Abstract: | This paper discusses the characteristics of the parallel kinematic machines in high speed machining, analyzes the limitations of the conventional machine tools which is characterized as the serial kinematics, and poses the design requirements which consists of direct drive technology, light weight complex construction and new machine kinematics for the realization of high speed machines. Based on the analysis of kinematics, dynamics and machining precision, the diagrams of the displacement, velocity, acceleration, and driving force are presented. Finally, such problems as backlash and singular workspace are analyzed, which need to be solved when putting parallel kinematics to the application in machine tools. |
