Visual evaluation system for straightness error based on LabVIEW

Abstract

Because of exiting inefficient and incomplete functional problems in traditional straightness error evaluation, Error measure and evaluation system based on virtual instrument was designed. Two endpoint link line, least-squares algorithm and minimum zone algorithm methods for evaluation straightness error were programmed by means of LabVIEW8.5, the corresponding data processing algorithms and program charts were given. Through experiments the validity of this software was proved, This software can realize visual evaluation.
