Optimization of two support spindle shaft on nonlinear elastic supports by rigidity characteristics
Bulletin of the National Technical University «KhPI» Series: Dynamics and Strength of Machines, 2021 One of the main structural elements of metalworking machines is the spindle assembly (spindle), which is used to hold cutting tools or workpieces. The rigidity of the spindle assembly plays a decisive role in ensuring the accuracy and efficiency of the machine as a whole.
