Abstract： Aiming at decreasing the effect of the abrasion value of the cylindrical grinding wheel of the gantry vertical plane grinder acting on the processing accuracy of the large flat，an reign measurement device was developed based on the analysis of the characteristics and process of the wheel wear. The working principle，mechanical structure，hardware design，software functions and the applicable occasions of the measuring device were presented in detail. The experimental results indicate that not only the automatic measurement of the abrasion value of the cylindrical grinding wheel is realized by the reign measurement device，but also the straightness error of the processed plane precisely. Its measurement accuracy for abrasion value achieves 0.009 mm and for straightness error is 0.008 mm/100 mm. It could provide measurement data for wheel wear compensation，improve the process accuracy and efficiency.
