Abstract
Zahtjevi za preciznost u suvremenoj proizvodnoj industriji doveli su do situacije da se trokoordinatni CNC mjerni uređaji nalaze u gotovo svim velikim, a nalazimo ih već i u manjim radionicama. Međutim, većina tih strojeva koristi se kao alat za ispitivanje gotovih proizvoda, da li isti zadovoljavaju određene specifikacije, obično primjenjujući opće pravilo da nesigurnost mjerila ne smije biti veća od jedne petine (idealno desetine) izmjerene vrijednosti. U ovom se radu opisuje usporedba takvog načina generalno usvojenim načelom i izračunate ponovljivosti i obnovljivosti CNC mjernog stroja. Usporedba se provodi u stvarnom radnom okruženju sa stvarnim proizvodima.
Abstract (english)
The requirements for precision in modern manufacturing industry has led to situation where three coordinate CNC measuring machines are found in almost all but smallest workshops. However, majority of those machines are used as inspection tool for pass/fail tests, usually applying general rule that the measuring machine uncertainty should be no more than one-fifth (ideally one-tenth) of measured value. In this paper comparison between such rule of the thumb approach and calculated reproducibility and repeatability of the measuring machine will be described. Comparison is performed in real work environment with actual products.
