Umsebenzi Oyinhloko we-CMM
Umshini wokulinganisa oxhumanisayo (i-CMM) iyithuluzi lokulinganisa ukunemba elisebenza kahle kakhulu elasungulwa ngasekupheleni kwawo-1960. Ukuvela kwalo, ngakolunye uhlangothi, kungenxa yezidingo zokuthuthukiswa kokukhiqiza. Okusho ukuthi, ukuvela kwemishini yokucubungula esebenza kahle kakhulu, ukuthuthukiswa okuqhubekayo kwezidingo zekhwalithi yomkhiqizo, kanye nokuthuthukiswa kobuchwepheshe bokucubungula obunezinhlangothi ezintathu obuyinkimbinkimbi kudinga imishini yokulinganisa esheshayo nethembekile ukuze ibambisane nayo; Ngakolunye uhlangothi, ngenxa yokuthuthukiswa kobuchwepheshe be-elekthronikhi, ubuchwepheshe bekhompyutha kanye nobuchwepheshe bokucutshungulwa kokunemba, kunikeza isisekelo sobuchwepheshe sokuvela kwe-CMM.
Ama-coordinate amathathu Umshini Wokulinganisa (CMM) uhlobo lwethuluzi lokuthola olusekelwe emishinini enembile, ukusetshenziswa okuhlanganisiwe kobuchwepheshe be-elekthronikhi, ubuchwepheshe bekhompyutha, ubuchwepheshe be-grating kanye nobuchwepheshe bokuphazamiseka kwe-laser. Imisebenzi eyinhloko ye-CMM yile:
1) Ingakwazi ukulinganisa amaphuzu okuxhumanisa endawo, futhi ingalinganisa kalula usayizi we-contour onezinhlangothi ezintathu kanye nokunemba kwesikhundla sezingxenye ezahlukahlukene. Ukulinganisa okunembile nokuthembekile, okuqinile emhlabeni wonke.
2) Ngenxa yokukhanga kwekhompyutha, ingaba lula ekubalweni kwedijithali nasekulawulweni kohlelo, futhi inobuhlakani obuphezulu. Ngakho-ke, ayikwazi nje ukukala kalula ubukhulu besikhala obunezinhlangothi ezintathu, kodwa futhi ikwazi ukulinganisa okusebenzayo kanye nokutholwa okuzenzakalelayo. Embonini yokukhiqiza isikhunta, ikhombisa ngokugcwele ukuguquguquka kokulinganisa kanye nokuhlukahluka kwezinto zokulinganisa.
I-CMM Isetshenziswa kabanzi ekukhiqizeni imishini, ekukhiqizeni amathuluzi, embonini ye-elekthronikhi, eminyangweni yezindiza kanye neyokuvikela kazwelonke, ifaneleka kakhulu ekulinganiseni izingxenye zebhokisi zebanga lembobo kanye nebanga lobuso, isikhunta, ukuphonswa okunembile, amabhodi wesekethe kagesi, igobolondo lezimoto, izingxenye zenjini, amakhamera kanye nomzimba wendiza onezingxenye zokusebenza ezigobile isikhala.
Indima yomshini wokulinganisa ama-coordinate ayikona nje kuphela ukuthi wandisa ama-coordinate eyodwa noma ezimbili kunethuluzi lokulinganisa lendabuko, ukuze into yokulinganisa ibe nkulu, futhi amandla ayo abonakala nangokuthi isibe ngumlingani obalulekile weminye imishini yokucubungula. Isibonelo, ingalungiselela ngempumelelo itheyiphu yedijithali enezimbobo zamathuluzi omshini we-CNC, futhi lo msebenzi kunzima ukuwuqeda ngezindlela zendabuko ngenxa yobunzima obukhulayo bendawo yokucubungula, ngakho-ke inesihloko esithi "isikhungo sokulinganisa" kanye ne-CNC "isikhungo somshini".
