Evaluation of measurement results in coordinate measuring technique based on a CAD model

V diplomskem delu obravnavam izdelavo merilnih programov, izvajanje meritev in vrednotenje merilnih rezultatov na osnovi CAD modela pri meritvah dimenzij, oblik in lege na koordinatni merilni napravi DEA Global. Obravnavani in primerjani so načini kontaktnega in brezkontaktnega merjenja v treh koordinatah, njihove prednosti in pomanjkljivosti. Izvedena je primerjava med vrednotenjem merilnih rezultatov po konstrukcijski risbi in vrednotenjem merilnih rezultatov na osnovi CAD modela, ter predstavljene prednosti slednjega. Uporaba CAD modela je predstavljena na primeru meritev geometrijskih toleranc grelnika nafte, ki je v fazi razvoja. Razvoj potrebuje hitro in natančno vrednotenje merilnih rezultatov, na osnovi katerih se izvaja korekture na izdelku in orodjih.In the thesis I discuss the elaborate of measurement programs, measurements and evaluation of measurement results based on CAD model in measuring the dimensions, shape and position on the coordinate measuring device DEA Global. Discussed and compared these modes of contact and contactless measurement of three coordinates and their advantages and disadvantages. Comparison is made between evaluation measurement results according to design drawings and evaluation measurements results based on CAD model, and presents the advantages of the latter. Use of CAD model is presented in the case of measurement of geometric tolerance, of oil heater, which is under development. Development requires rapid and accurate valuation of measurement results based on which is made a correction on the product and tools
