Paper Abstract

Nowadays in china the straightness of guiding parts such as guiderod and guideway whose straightness required is very high is mostly measured in off-line state. The staightness of machine moving part'' s track (slide carriage working bench) is also measured with the help of comparative measurement with standard core rod or level scale. So we introduce straight measurement principle of two-point type and measure directly the straightness error of a workpiece and the straightness error of the machine motion locus by sampling densely. After the data are processed and the errors are seperated by 8095 microcomputer the straightness diagram and assessed result data of workpiece generatrix and slide will be obtained. Based on YZCS-1A Comprehensive measurement instrument as a hardware the system can be used not only to measure straightness error in static on-line state but also to measure and analyse it in dynamic state.
