A comparative analysis of measurement results obtained in measuring parts having complex geometric shapes by means of 3D scanners and CMM

Abstract

This study compares the dimension measurements results obtained for two parts that had convex and concave parabolic profiles. Three different measurement systems were employed for measurements: coordinate measuring machine (CMM), 3D laser and 3D photometric scanners. It was found using Student’s t – test that results obtained by CMM measuring system are statistically significantly (p < 0.001) more accurate than results obtained by means of 3D laser and 3D photometric scanners. It was also established that results obtained by means of 3D laser scanning system are statistically significantly more accurate (p < 0.05) than those obtained by means of 3D photometric scanning system.

Matavimų rezultatų, gautų matuojant sudėtingos geometrinės formos detales 3D skeneriais ir koordinatine matavimo mašina, lyginamoji analizė


Santrauka

Straipsnyje lyginami dviejų detalių matmenų matavimų rezultatai, gauti skirtingomis matavimo sistemomis: koordinatine matavimo mašina (KMM), 3D lazeriniu skeneriu ir 3D fotometriniu skeneriu. Buvo matuojamos iškilaus ir įgaubto paraboloidinio profilio detalės. Išanalizavus matavimo rezultatus gauta, kad KMM matavimo sistema gauti rezultatai pagal Stjudento t kriterijų (t-test) statistiškai reikšmingai (p < 0,001) tikslesni už rezultatus, gautus 3D lazeriniu ir fotometriniu skeneriais. Taip pat nustatyta, kad rezultatai, gauti 3D lazerine skenavimo sistema, yra statistiškai reikšmingai tikslesni (p < 0,05) už gautuosius 3D fotometrinio skenavimo sistema.

Reikšminiai žodžiai: KMM, fotometrinis skeneris, lazerinis skeneris, 3D modelis.
