Ai. Astashenkov et al., ANALYSIS OF THE ERRORS OF AUTOMATED COORDINATE METHODS FOR MEASURING STEP PARAMETERS OF MACHINED SURFACES, Measurement techniques, 39(8), 1996, pp. 886-891
Computer coordinate methods of measurement are now becoming the main m
ethods for the metrology of surface quality. Nevertheless they lead to
certain additional specific errors which are manifested to the greate
st degree in the measurement of step parameters and the parameters of
extremum values of surface coordinates. An estimate is given below of
the errors of computer coordinate methods of measuring step parameters
of the roughness profile of machined surfaces and practical recommend
ations are given concerning the choice of measurement regimes.
