Ezweni lanamuhla lokukhiqiza ngokunemba, ukunemba kuseyiyona nto efunwa kakhulu. Kungakhathaliseki ukuthi umshini wokulinganisa ohlanganisiwe (i-CMM), ipulatifomu yelabhorethri yokukhanya, noma imishini ye-semiconductor lithography, ipulatifomu ye-granite iyitshe legumbi elibalulekile, futhi ukuthamba kwayo kunquma ngqo imikhawulo yokulinganisa yesistimu.
Abantu abaningi bacabanga ukuthi kule nkathi yokwenza izinto ngokuzenzakalela okuthuthukile, ukukhanda ipulatifomu yegranite kumele kwenziwe ngamathuluzi omshini we-CNC azenzakalelayo ngokuphelele. Kodwa-ke, iqiniso liyamangaza: ukuze kufezwe ukunemba kokugcina ezingeni le-micron noma ngisho ne-submicron, isinyathelo sokugcina sisathembele ekugayeni ngesandla ngabachwepheshe abanolwazi. Lokhu akulona uphawu lokubuyela emuva kwezobuchwepheshe, kodwa kunalokho ukuhlanganiswa okujulile kwesayensi, ulwazi, kanye nobungcweti.
Ukubaluleka kokugaya ngesandla kulele kakhulu emandleni ayo okulungisa aguquguqukayo. Ukugaya nge-CNC empeleni "kuyikhophi engaguquki" esekelwe ekunembileni okungokwemvelo kwethuluzi lomshini, futhi ayikwazi ukulungisa njalo amaphutha amancane ayenzeka ngesikhathi sokugaya. Ukugaya ngesandla, ngakolunye uhlangothi, kuwumsebenzi ovalekile, odinga ochwepheshe ukuthi bahlole njalo ubuso besebenzisa amathuluzi afana namazinga kagesi, ama-autocollimator, nama-laser interferometers, bese benza ukulungiswa kwendawo ngokusekelwe kudatha. Le nqubo ivame ukudinga izinkulungwane zezilinganiso kanye nemijikelezo yokupholisha ngaphambi kokuba ubuso bonke bepulatifomu bucwengisiswe kancane kancane bube sezingeni eliphezulu kakhulu lokuthamba.
Okwesibili, ukugaya ngesandla akunakuthathelwa indawo ekulawuleni ukucindezeleka kwangaphakathi kwe-granite. I-Granite iyinto yemvelo enokusatshalaliswa okuyinkimbinkimbi kokucindezeleka kwangaphakathi. Ukusika ngomshini kungaphazamisa kalula lokhu kulinganisela esikhathini esifushane, okuholela ekuguqukeni okuncane kamuva. Ukugaya ngesandla, nokho, kusebenzisa ukucindezela okuphansi nokushisa okuphansi. Ngemva kokugaya, ingcweti ivumela umsebenzi ukuthi uphumule, okuvumela ukucindezeleka kwangaphakathi kwezinto ukuthi kukhululeke ngokwemvelo ngaphambi kokuqhubeka nokulungisa. Le ndlela "ehamba kancane futhi eqinile" iqinisekisa ukuthi ipulatifomu igcina ukunemba okuzinzile ngokusetshenziswa kwesikhathi eside.
Ngaphezu kwalokho, ukugaya ngesandla kungadala izakhiwo zobuso obuyi-isotropic. Amamaki okugaya ngomshini avame ukuba aqondiswe, okuholela ekungqubuzaneni okuhlukahlukene kanye nokuphindaphindeka ngezindlela ezahlukene. Ukugaya ngesandla, ngokusebenzisa inqubo eguquguqukayo yomenzi wezandla, kudala ukusatshalaliswa okungahleliwe nokufanayo kwamamaki okuguga, okuholela ekhwalithini yobuso ehambisanayo kuzo zonke izindlela. Lokhu kubaluleke kakhulu ezinhlelweni zokulinganisa nokunyakaza okunembile kakhulu.
Okubaluleke kakhulu, i-granite yakhiwe ngamaminerali ahlukahlukene, njenge-quartz, i-feldspar, ne-mica, ngalinye linokuguquguquka okuhlukile kobulukhuni. Ukugaya ngomshini kuvame ukuholela ekusikweni ngokweqile kwamaminerali athambile kanye nokuphuma kwamaminerali aqinile, okudala ukungalingani okuncane kakhulu. Ukugaya ngesandla, ngakolunye uhlangothi, kuncike kokuhlangenwe nakho kanye nomuzwa womdwebi. Bangakwazi ukulungisa njalo amandla kanye ne-engeli ngesikhathi senqubo yokugaya, bandise ibhalansi phakathi kokushintshashintsha kwamaminerali futhi bafinyelele indawo yokusebenza efanayo futhi engagugi.
Ngandlela thile, ukucutshungulwa kwamapulatifomu e-granite anembile kakhulu kuwuphawu lobuchwepheshe besimanje bokulinganisa ngokunemba kanye nobuciko bendabuko. Imishini ye-CNC inikeza ukusebenza kahle kanye nesimo esiyisisekelo, kuyilapho ukuthamba okuphelele, ukuzinza, kanye nokufana kumele kufezwe ngesandla. Ngakho-ke, yonke ipulatifomu ye-granite esezingeni eliphezulu imelela ukuhlakanipha nokubekezela kwabakhi abangabantu.
Kubasebenzisi abaphishekela ukunemba okuphelele, ukuqaphela ukubaluleka kokugaya ngesandla kusho ukukhetha into ethembekile ezohlala isikhathi eside. Kungaphezu nje kwengcezu yetshe; kuyisisekelo sokuqinisekisa ukunemba okuphelele ekukhiqizeni nasekulinganisweni.
