This paper analyzes the calculation method of grinding temperature at home and abroad, and points out the advantage of finite element method and finite difference method in time recursion to deal with two-dimensional unsteady grinding temperature field. The calculation formula of grinding temperature which has important theory and practical value is drawn, the corresponding computer program is drawn up, the temperature field under different grinding dosage is numerically calculated and a large number of experiments are compared, and the Peklenik temperature measurement method is adopted by computer Achieve data collection. The experimental results show that the calculated values are in good agreement with the experimental values and some important conclusions are drawn.
