Abstract： ANSYS software was used to simulate the instantaneous temperature fields in the polishing processes with abrasive cloth wheel using a rectangular heat source loading method. The temperature distribution on the blade surfaces and along the blade thickness direction in the polishing processes was studied，and the influences of processing parameters on the polishing temperature was explored. The results show that as the polishing process progresses，the polishing temperature distribution gradually stabilizes. When the polishing temperature stabilizes，the temperature values of the machined parts of the bladeat different depths tend to be consistent，while the temperature of the machining parts decreases continuously along the depth direction; the polishing temperature gradient graduall decreases from the contact area being machined to the machined area；the polishing temperature increases with the increase of spindle speed，the effects of feed speed on the polishing temperature are not significant and the polishing temperature is positively correlated with the tangential polishing forces；the deviation rates between the measured and the simulated temperature values are not more than 10% ，indicating that the good consistency and high accuracy of the simulation.
