Paper Abstract

Ultra-precision machine components such as linear motion tables and rotary bearings are necessary to realize ultra-precision mechanisms and machines. In order to produce these components the evaluation of their accuracy is essential. This paper describes a measuring method of straight motion accuracy of a linear table with one meter working length. The method is based on the sequential three-point one but in the method it is possible to eliminate the influence of the zero-inequality of sensors. The method also makes use of merits of the conventional reversal one but there is no need to reverse a long straightedge.
