Report on the topic: “Problems of using datum-based methods to form deviations and surface waviness”

The paper discusses the state-of-the-art on research and development of activities relating to wider application of datum-based methods in the field of measurements of surface texture of machine parts. Despite the fact that datum-based methods are well-known, in hitherto practice their application area has been limited. Research activities car-ried out by authors indicate that datum-based methods can be very useful as a part of computer-aided measurement systems allowing conducting measurements directly on a machine tool (in-situ measurements). One of the results of the research work conducted by authors was prov-ing that datum-based methods can be applied to evaluate cylindricity deviations and, with some limitations, to evaluate surface waviness of machine parts.
