Problems solved by technology

However, the cylindricity error measurement uses the laser diffraction method and the part projection image method. The disadvantages are: the measurement accuracy is affected by many environmental factors, and the repeatability of the measurement results is poor. In addition, because the method uses rotating sampling, the sampling data is small. The sampling efficiency is low, the measurement accuracy of this measurement method is low, and the resolution of the measurement results is low
