Research On The New Type Instrument Of Small Size Part's Linearity

The quantity and the capability of the measure instrument are effected geometry element (size, shape, position, etc.) of parts. Error of shape is one of important geometry element that describes error of parts. As one of error of shape, linearity effect directly precision, capability and quantity of instrument. At some situation, linearity is determinant indeed. Along with developing of science and technology, parts request more minimize and more precise, so that there is higher request to the measure of small size parts. Measure technique of small size part's linearity and plan obtaining level is draggled. On the base, the task took instrument of small size part's linearity as mostly researching object and researched on the measure theory.The article discuss mostly of researching to instrument of small size part's linearity founded on air lubricated guide. First, it stated traditional measure means of linearity, as well as researching level on air lubricated guide inside and outside. Second, it probes into involved basic theory in the article (theory of air lubricated, assess means of linearity error). On the base, analyzing and demonstrating the feasibility and scientificity of the task analyzing and researching the measure elements and specialty of small size parts, as well as concretely requiring in fact, thereis a whole design frame about the instrument, moreover emphatic discussing air lubricated guide, driver and dealing with measure data with software. Finally, after experimenting with the instrument, we deal with and analyzed the data. Result indicates that the measure's system of small size part's linearity appeases measure's request and collects automatically data and analysis image, which provide us a foundation on which we exploit instrument of small size part's linearity.
