Experiments of internal thread grinding and flat groove grinding show that grinding efficiency and quality can be significantly improved by increasing the wheel speed. According to the characteristics of internal thread grinding and flat groove grinding, the grinding force measurement experiment is designed. The equivalent substitution method is used to compare with the Grinding Force per Unit Area in surface grinding test under the same conditions. The experimental results show that the measurement error of Grinding Force per Unit Area is less than 25 %.
