The measurement of the flatness error of the surface of large mechanical parts has been an intractable problem at home and abroad. Using traditional methods, such as the level method and the self-collimator method, the measurement period is long and the measurement accuracy is not high. It is not suitable for the needs of the large-scale surface flatness error due to the development of science and technology in recent years. In recent years, research in this area has been carried out in China, and several feasible high-precision measuring instruments have been developed, such as mirror flatness measuring instrument and double-beam scanning method for high-precision large-scale plane measurement.
