ASPECTS CONCERNING THE MEASUREMENT OF FLATNESS DEVIATIONS
Abstract
This article points out the problems resulting from the calculation of flatness deviations against the adjacent surface defined according to SR EN 1101-2017 and proposes the use of a larger number of measurement points for improved accuracy, along with the identification of a reference plane surface with the help of matrix calculations. All deviations should be re-calculated by comparison to this reference plane. In order to reduce the large number of errors resulting from many rounding applied, this paper proposes the method of deviation measurement at symmetrical coordinates, while the calculation of the reference plane surface would be made with the help of an original method, whereby the number of operations is reduced to a minimum in order to increase accuracy.
