Simulation and Experiment Study for Spindle of Numerical Control Machine Tool
Processing precision of numerical control machine tool is decided by static rigidity and dynamic rigidity of spindle to a great extent. 3- D model of numerical control machine tool was established by using parametric modeling and virtual assembly function of Solidworks. Simultaneously, simulation and Experiment study of the spindle static rigidity was carried out, and practicability of the simulation analysis method was proved. The result indicates that the biggest deformation appears in the front of spindle. The static rigidity of spindle can been enhanced greatly by enhancing three carriage-feed system’s static rigidity of machine tool. The simulation for the dynamic rigidity of spindle indicates that the dynamic rigidity of spindle is uniformly distributed and resonance can be avoided effectively by the spindle when working.
