Abstract

Accurately straightness measuring has a direct relation to the promotion of the machine precision. In the process of straightness measurement, since the measuring interval has a great impact on the accuracy and efficiency of large-size straightness measurement, and there is no detailed measurement interval calculation method at present, it is necessary to make a deeply research to the measuring interval. This paper gives theoretical derivation to the measuring interval based on the Nyquist sampling theorem. Maximum frequency M and the number of measuring points in one period N are determined based on measurement tolerance, and then calculate the optimal theoretical measuring interval. Finally, measure the straightess of the guide rail under diferent measuring interval including the optimal one. Validate the calculation method through the straightess measuring experiment. The experimental results show that the optimal theoretical measuring interval derived in this paper is suitable, which proves the correctness of the calculating method.
