What is it about?
The characters of parallel or serial-parallel machine tool are: It is difficult to determine the machine point and the working space is small and the NC system is not perfecting of parallel machine tool. It is droved by parallel mechanism and improved the stiffness of machine tool.

Why is it important?
It is easy to process the part of complex surface, such as aircraft wing and turbine blade, because the machine tool has high machining accuracy and processing speed. However the dynamics coupling problem of parallel or serial-parallel machine tool is the premise of the solution of structural optimization design, parameter calibration, accurate control and so on. It has important practical value to determine the working situation, working space and the force of tool for machine tool and the processing quality of part.
