| Summary: | The most important concepts regarding precision when designing, building and setup of the machine tools are discussed. Therefore, in the present article, the most important design principles when developing a machine tool are explained. Besides, the most common method used nowadays for quantifying the uncertainty in machine tools is detailed: the error budged. Moreover, the principles required for a proper design are described. Finally, the most important global standards for measur-ing the precision of a machine tool are reviewed.; Zehaztasunaren ikuspuntutik makina-erreminten diseinuan, eraikun-tzan eta martxan jartzean kontuan eduki behar diren puntu garrantzitsuenak bildu dira ikerlan honetan. Horregatik, artikulu honetan, makina-erremintaren diseinu-printzipio garrantzitsuenak azaltzen dira. Gainera, makina-erremintetan ager daitezkeen erroreen ondoriozko ziurgabetasuna zenbatesteko gaur egun gehien erabiltzen den metodoan sa-kontzen da: errore-aurrekontua. Are gehiago, diseinu egokirako kontuan hartu behar diren printzipioak deskribatzen dira. Azkenik, makina-erreminta muntatu ostean, ha-ren zehaztasuna zenbatesteko existitzen diren nazioarteko arau garrantzitsuenak aztertu dira.
