This paper presents measurement of the angular error motions of a precision linear stage by using a high resolution clinometer in the production process of the stage, where the measurement is repeatedly carried out together with a hand scraping operation for correction of the form errors of the stage guideways. Differing from a conventional autocollimator, the clinometer does not require a reference mirror on the stage since its angle reference is the direction of the gravitational vector. In this paper, two clinometers are employed to measure roll error motion of a linear stage, while eliminating the influences of external vibrations.
