Abstract:

Straightness error measurement is a basic measurement item in the field of geometric quantity. It is the basis of flatness, parallelism, verticality and coaxiality measurement. It has absolute influence on the performance of products. In this paper, the straightness measurement method of indoor large length standard device is mainly solved. In this paper, the laser interferometer is used to collect and splice the straightness of indoor large length standard device within the range of 50 m. The final results show that the horizontal straightness is 0.43 mm and the vertical straightness is 0.39 mm when the endpoint method is used. The horizontal straightness is 0.43 mm and the vertical straightness is 0.41 mm when the least square method is adopted.
