摘要:
This paper presents for the first time the concept of anisotropy of measurement for complex curved surfaces. Based on the theory of differential geometry, the relation between measurement error and micro-structure & form of curved surfaces is studied, which is existence proof of anisotropy, and also the basic rule of anisotropy is clarified. Through anisotropic analysis of the measurement for complex curved surfaces, series of conclusions relating to that are obtained. Those conclusions have not only theoretical meaning but also far-reaching practical value on the following aspects: precision instruments design, error budget, measuring method design, and etc..
