Grinding active measurement instrument is widely used in grinding process. In order to improve the intelli- gence degree, measurement accuracy and operability of the active measurement instrument, the theory and application of active measurement technology were studied and analyzed, and a novel grinding active measurement instrument was developed on the basis of precision measurement and control technology. The hardware system of the active measure- ment instrument was designed on the basis of bus modularity mode of industrial personal computer motherboard, and the key data processing technologies in the online measurement process were studied. At the same time, the software control system of the measurement controller was also developed using the configuration software development plat- form, which effectively ensures the high speed data acquisition and high accuracy data processing and control of the new active measurement instrument. The active measurement and control function of the new active measurement in- strument was implemented. The experiment measurement and analysis of the active measurement instrument were car- ried out, and experiment results show the effectiveness and feasibility of the instrument. The new instrument has been used in practical grinding process, and achieves good results in terms of intelligence level, display intuitionistic char- acteristic, operability, and measurement and control precision
