Abstract

The invention discloses a cylindricity three-section measuring method. The method comprises the steps that (1) three sections are selected on the side face of a cylindrical workpiece to be measured to be provided with three sensor sets; (2) the radius difference of the three sections is measured; (3) the axis linearity error is measured; (4) the cylindricity is measured. In this way, the cylindricity three-section measuring method has the advantages of achieving design optimization, being novel, stable in performance, free of positioning, convenient to operate, precise and accurate, improving the efficiency, being suitable for measuring devices in a production line and the like, and has the wide market prospect when popularized.

Description

technical field [0001] The invention relates to the field of precision measurement, in particular to a three-section measurement method for cylindricity. Background technique [0002] Cylindricity error is one of the main geometry errors controlled in precision machining. The cylindricity of the workpiece is the minimum distance that the cylindrical surface is contained in two coaxial cylindrical surfaces. Cylindricity is the combination of section roundness, taper of different sections and generatrix straightness. [0003] The existing measurement method is to take coordinate points on the surface of the workpiece and then use the least square cylinder method, the maximum inscribed cylinder method, the minimum circumscribed cylinder method, and the minimum contained area cylinder method to calculate the cylindricity of the workpiece. However, the existing methods are sensitive to environmental requirements, most of them need positioning, and can only be used on the measur...
