Abstract
The possible reason for the incorrect form deviations calculated using an algorithm available in the selected software of coordinate measuring machine was identified. This method is available in the Calypso software and it is based on local deviations calculated at nominal points. The analysis was made for the selected examples of free-form surfaces. There are presented the results of numerical investigations based on simulations of coordinate measurements of selected object. The measured points were generated with assumed values of scatter in relation to the nominal profiles of the analyzed product. The simulations were made using 3 selected methods for computing the form deviations and various distances between the measured points. In order to verify the results of simulation studies there were made experimental investigations. The experimental investigations were done using selected coordinate measuring system and chosen measurement parameters. The results of performed measurements confirm the simulation results.
Highlights
Wskazano możliwą przyczynę błędów w obliczaniu odchyłek kształtu z wykorzystaniem algorytmu wybranego oprogramowania współrzędnościowej maszyny pomiarowej
In the step there are computed local deviations associated with the distances between nominal points and the curves representing real shape of measured object
The form deviation is computed based on the local deviations
Summary
The possible reason for the incorrect form deviations calculated using an algorithm available in the selected software of coordinate measuring machine was identified This method is available in the Calypso software and it is based on local deviations calculated at nominal points. The simulations were made using 3 selected methods for computing the form deviations and various distances between the measured points. Symulacje zrealizowano z użyciem 3 wybranych metod obliczania odchyłek kształtu oraz różnych odległości między punktami pomiarowymi. Badania eksperymentalne zrealizowano z użyciem wybranego współrzędnościowego systemu pomiarowego oraz wybranych parametrów pomiaru. Based on obtained results of numerical investigations there is indicated one potential reason for incorrect computations of form deviations using the method N, which is available in the Calypso software. The last part of the paper contains conclusions following the investigations
