To predict the effect of conventional short arc grinding on the machining depth of honeycomb rings under different voltages,the simulation heat source formula for the temperature field of short arc grinding honeycomb rings was studied.Focusing on the relationship between heat source coefficient and voltage,the heat source formula obtained through ANSYS software was studied,and the temperature field of short arc grinding honeycomb ring was simulated.The heat source formula suitable for short arc conventional grinding of honeycomb ring under different voltages was studied.Through the simulation results of temperature field,the temperature distribution and change trend of honeycomb ring grinding under different voltages were analyzed.The results show that the obtained heat source formula is suitable for the temperature field of short arc grinding honeycomb ring machining under different voltages.The variation and distribution of the simulated temperature cloud maps are in line with the actual situation of short arc grinding machining.The error of the simulation results is within 5.9%,with good agreement,providing a theoretical basis for predicting machining depth.
