Abstract :
In this paper, the thermal characteristics of the CNC machine spindle system is simulated based on finite element method. The heat boundary conditions of the finite element model are calibrated by comparing with the experimental results. Furthermore, the spindle system thermal errors are calculated and reduced by two approaches: rational arrangement of the heat-dissipating rib plates and parametric optimization design of finite element model.
