20.500.12556/RUL-119183 Analiza pnevmatskega merilnega sistema za dimenzijsko kontrolo batov Analysis of a pneumatic measuring system for dimensional control of spools V diplomskem delu je obravnavana analiza pnevmatskega merilnega sistema za merjenje batov v hidravličnih ventilih. Bati morajo biti brušeni v toleranci nekaj mikrometrov, za izboljšanje kvalitete batov in izboljšave poteka proizvodnje pa je treba zagotoviti ustrezen merilni sistem, s katerim nadzorujemo proizvodnjo batov. Za analizo merilnega sistema smo izbrali eno od metod šest sigma, s katero izračunamo ponovljivost in obnovljivost merilnega sistema. V delu so predstavljene tri analize. Prva je analiza mehanskega merilnega sistema, ki deluje na principu dvotočkovnega merjenja, nato pa sta predstavljeni dve analizi pnevmatskega merilnega sistema, ki deluje na principu merjenja povprečnega premera bata. The diploma thesis deals with the analysis of a pneumatic measuring system for spools in hydraulic valves. The spools must be ground to a tolerance of a few micro meters, and in order to improve the quality of the spools and the production process, an appropriate measuring system must be provided to control the production of the spools. For the analysis of the measuring system, we chose one of the Six Sigma methods to calculate the repeatability and reproducibility of the chosen measuring system. The thesis presents three analyses. The first one is the analysis of a mechanical measuring system operating on the principle of two-point measuring method, the other two analyses comprise a pneumatic measuring system which is based on measuring the average diameter of a spool. pnevmatski merilni sistemi merilni obroči šest sigma analiza merilnih sistemov ponovljivost in obnovljivost meril pneumatic measuring systems gauge rings six sigma measuring system analysis gauge repeatability and reproducibility true false false [M.
