Iwo matatu-anoronga, anonziwo dimension, muchina wekuyera kurongeka, unonzi CMM.Icho chiridzwa chinoshanda chekuyeresa chakagadzirwa muma1960s.Izvo zvakabuda nekuda kwepamusoro-kushanda machining e otomatiki muchina maturusi uye CNC muchina maturusi, pamwe nekudiwa kwekukurumidza uye yakavimbika yekuyeresa michina yekugadziriswa kweakawanda uye akaomarara maumbirwo.

Parizvino, kuyerwa kwehutatu-kurongeka kwave kushandiswa zvakanyanya mumaindasitiri akasiyana sekugadzira michina, indasitiri yemotokari, indasitiri yemagetsi, indasitiri yezvemhepo, nezvimwewo, uye yave chinhu chakakosha chekuyeresa chepamusoro chekuongorora maindasitiri uye kutonga kwemhando.Kune edu akasarudzika asiri-akajairwa magaji, iwo matatu-anoronga kuyerwa chinhu chakakosha chekuyedza michina.Mushure mekunge tawana zvigadzirwa zvemutengi kudhirowa uye dhizaini chirongwa chegage chinosangana nezvinodiwa zvechigadzirwa uye mutengi agutsikana, zvinodikanwa.Tanga matanho ekugadzirisa mune inotevera nhanho, saka isu tinofanirwa kushandisa yedu-yechitatu-yekubatanidza kuyerwa, nekuti iko kurongeka kwemudziyo wacho kwakakwira zvakanyanya, saka shandisa iyo kuyedza kurongeka kwechikamu chimwe nechimwe chegeji redu, kune gage pacharo zvakanyanya. inovimbisa huchokwadi hwezvishandiso zvedu zvekuongorora.Semuenzaniso, imwe nzvimbo yegeji, flatness uye chimiro chake zvinosanganisira zvimwe zvikamu zvemotokari.Tese tinogona kuwana saizi chaiyo nekuona iyo coordinate kuyerwa
