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.
