The direct measurement mode of the high-precision measuring tape is that a plurality of measuring points are taken between guide rails by the measuring tape to measure, and the measuring point data is compared and judged to determine the parallelism of the guide rails. The laser interferometer measuring method needs to install a laser interferometer and a reflecting mirror on a guide rail sliding block, needs to erect an interference mirror, measures at a plurality of point positions by adjusting the positions of the interferometer, the reflecting mirror and the interference mirror, and judges the parallelism through software reading.
The measurement by the high-precision measuring tape is easy to operate, but the requirement of the equipment on the parallelism of the two guide rails cannot be met due to poor precision.
