| Abstract: | The connection performances of the spindle/toolholder interface in high speed NC machine has important influence on machine tool accuracy and process stability. With the example of HSK - E63, based on nonlinear finite ele- ment method （FEM） , the contact performance of the spindle/toolholder interface under high rotational speed was investiga- ted, the effect of magnitude of interference, clamping force and rotational speed on the contact pressure and clearance dis- tribution were discussed in detail. The results can he used as theoretical consideration to design and optimize the high speed spindle/toolholder interface. |
