【 摘 要 】

Both instrumental errors and method errors of measuring tools, depending on reference values deviation, should be taken into account in measurement accuracy tolerance calculation. Uncorrected form deviations of measuring surfaces originate from dimensions procedural errors. A geometrical representation of a smooth cylindrical pin specifying primary errors, coordinate systems and bases is developed. The measuring methods of cylindrical pin form deviation in longitudinal and cross sections are developed based on this model. According to the measurement data realistic pin surfaces are constructed. The form deviation measurement rules are proposed. The mentioned measurement methods reveal procedural errors of measurement that depend on the kind of form deviation and error values.
