The Research of Data Acquisition and Control Method about On-Line Measurement System on High Precision of Large Diameter
The system bases on the theory of rolling-wheel to measure large diameter, by applying double counters to record the round grating’s signal and using the method of three rolling-wheels paralleling data acquisition, redundancy measurement and error amendment and so on, realizes the measurement of large axis workpieces’ diameter with high precision in on-line and dynamic condition. The experiment shows that the system can achieve the on-line dynamic measurement precision in m D µ 5 at the range of the diameter m m D 5 ~ 1 = complexly combining hardware and soft under the relevant control methods.
