Determining Structural Modes of HSK Tool System and Influential Factors
The mode analysis of the HSK tool system structure is the base for determining HSK high speed spindle-tool system dynamic performances. In this paper, considering the HSK63A tool system as the research object, by way of the dynamic finite elements analysis method (FEM), the finite element assembly model of HSKA63 tool system was established, the natural frequencies and the modal shapes were obtained under the free condition. Then, with the method of experimental modality analysis (EMA), the FEM results were determined whether the construction of the finite element modal was reasonable or not, the factors were discussed, such as tool diameters, tool length, connection conditions of shank and cutter etc, which affected the mode parameters of HSK tool system structure. The computing results can be offered for evaluating the tool system’s dynamic performances as the theoretic evidences.
