Abstract:
A method of adjusting in a surface texture measuring instrument a relative attitude of a work having a feature region along a fixed direction of a surface of the work, the method comprising the steps of:a) mounting the work on a stage in such a manner that the fixed direction becomes substantially aligned with a Y axis; b) moving the detector along a X axis in order to obtain a data of the feature region after deciding a position of the detector along the direction of the Y axis; c) storing n (n&gE;2) sets of data on the feature region of the work by repeating more than once a step b); d) calculating an amount of a relative attitude correction of the work with respect to the detector from determining n shape feature points from n sets of data on the feature region of the work and from determining a feature line connecting the n shape feature points; and e) adjusting the relative attitude of the work with respect to the detector on the basis of the amount of the relative attitude correction of the work.
