Abstract：The thermal deformation is a main factor which affects the machining accuracy of direct drive A/C axis CNC milling head.In this paper,the heat source and heat dissipation of CNC milling head were analyzed,and the finite element analysis was carried out.The temperature change of CNC milling head was continuously measured by the thermal infrared imager,and the deformation of rod connected with the milling head was measured by the API measuring instrument.According to the measured data,the model was used to compensate the thermal deformation.The experimental results showed that the heating and cooling of the C axis had a great influence on the machining accuracy of the CNC milling head,and the error was reduced to 0.001 56 mm by building the compensation system.
