Methods that can be applied to the measurement of cylindricity directly on the machine tool belong to the above-mentioned reference methods. The cylindricity deviation consists of a roundness deviation in various sections of a workpiece, relative change of its diameter and non-centricity of roundness profiles in relation to the nominal axis of the workpiece. The reference methods applied currently allow the measurement of roundness profiles in relation to fixed points of support in various cross-sections of the measured workpiece [10, 11, 12]. It is also possible to evaluate the relative difference of diameters. In traditional reference measuring systems, on the other hand, we cannot measure the non-centricity of profiles. That is why the authors proposed developing the reference measuring system for the measurement of cylindricity consisting of two connected sets of points of support, in relation to which the measuring sensor would move along precisely constructed shears
