| Abstract: | A finite element model on high-precision CNC vertical frustum of cone grinding machine is established. Through analysis of the heat source and heat load calculation methods, the temperature distribution is solved, and the thermal characteristics and thermal deformation of the vertical grinder are predicted after thermal-structural coupling solution. Then through analysis of thermal deformation impact on precision, the heating control, structure optimization and thermal error reduction measures are provided. |
