Abstract
Doktorsko delo zajema razvoj metodologije za razširjeno vrednotenje in popis geometrije zobnikov na osnovi optičnih meritev. Optične metode omogočajo hitrejše in celovitejše merjenje zobnikov ter posledično vrednotenje kakovosti z upoštevanjem geometrije v celoti in ne le z manjšim številom odsekov. Celovitejše merjenje in vrednotenje kakovosti omogoča stabilnejše določevanje obstoječih in razvoj novih geometrijskih kakovostnih parametrov. V sklopu doktorskega dela so razviti algoritmi za določevanje standardnih in novih geometrijskih parametrov. Poravnava merjenih podatkov in referenčne geometrije je predpogoj za ustrezno kontrolo kakovosti, zato je raziskan vpliv poravnave in razvita nova metoda poravnave. V vrednotenje kakovosti je prav tako vključen nadzor dimenzij in toleranc s pomočjo opredelitve izdelka na osnovi modela, ki omogoča avtomatski prenos informacij in zmanjša možnost napak pri ponovnem vnosu informacij. Dodatno je razvita metodologija za prikaz rezultatov na dejanskem zobniku s pomočjo obogatene resničnosti.

Title:A method for analysing the geometric quality of gears based on optical measurements and CAD model
Abstract:
The doctoral thesis covers the development of a methodology for extended evaluation of gear geometry based on optical measurements. Optical methods offer fast and comprehensive measurements of gears and consequently enable their evaluation based on the entire geometry and not just a small number of sections. More comprehensive measurement and evaluation of geometrical quality enables robust determination of standard and development of new geometric quality parameters. As part of the doctoral thesis, algorithms for determining standard and new geometric quality parameters are developed. The alignment of measured data and reference geometry is a prerequisite for proper quality control, thus the impact of alignment and the development of a new alignment method were investigated. The quality evaluation includes the control of dimensions and tolerances through model-based definition, which allows an automatic transfer of information and reduces the possibility of errors in re-entering information. Additionally, a methodology to display the results on the actual gear using augmented reality is developed.

Keywords:gears, optical metrology, quality control, geometrical quality parameters, alignment, augmented reality, model-based definition
