| Abstract: | The dynamic and static characteristic is studied through the FEA model of the machine tool, According to the practical machining ~ the definition of static stiffness is given. When the headstock moves along the slider, the changes of the dynamic characteristic is investigated, The contribution of various assemblies to the whole stiffness is studied also. The conclusion is the important theory base of the design and remodeling. |
