Emhlabeni wanamuhla wokukhiqiza okunembayo, ukunemba kusewumgomo ophakeme kakhulu. Kungakhathaliseki ukuthi umshini wokulinganisa wokuhlanganisa (i-CMM), iplathifomu yaselabhorethri yokubona, noma okokusebenza kwe-semiconductor lithography, inkundla yegwadle iyitshe legumbi elibaluleke kakhulu, futhi ukucaba kwayo kunquma ngokuqondile imikhawulo yokulinganisa yesistimu.
Abantu abaningi bacabanga ukuthi kulesi sikhathi sokuzenzakalela okuthuthukisiwe, ukwenziwa kweplathifomu yegwadle kumele kwenziwe ngamathuluzi omshini we-CNC azishintshayo ngokuphelele. Kodwa-ke, iqiniso liyamangaza: ukuze uthole ukunemba kokugcina ezingeni le-micron noma ngisho ne-submicron, isinyathelo sokugcina sisancike ekugayeni okwenziwa izingcweti ezinolwazi. Lokhu akulona uphawu lokusalela emuva kwezobuchwepheshe, kodwa kuwukuhlanganisa okujulile kwesayensi, ulwazi, nobungcweti.
Inani lokugaya mathupha lilele ngokuyinhloko emandleni ako okulungisa aguqukayo. I-CNC machining empeleni “iyikhophi emile” esekelwe ekunemba kwemvelo kwethuluzi lomshini, futhi ayikwazi njalo ukulungisa amaphutha amancane okwenzeka ngesikhathi somshini. Ukugaya mathupha, ngakolunye uhlangothi, kuwumsebenzi ovaliwe, odinga ukuthi izingcweti zihlole ngokuqhubekayo indawo engaphezulu zisebenzisa amathuluzi afana namaleveli e-electronic, ama-autocollimator, nama-laser interferometers, bese enza ukulungiswa kwendawo okusekelwe kudatha. Le nqubo ivamise ukudinga izinkulungwane zezilinganiso nemijikelezo yokupholisha ngaphambi kokuba yonke indawo yesikhulumi icwengwe ibe sezingeni eliphezulu kakhulu lokucaba.
Okwesibili, ukugaya okwenziwa ngesandla akubuyiseleki ngokulinganayo ekulawuleni izingcindezi zangaphakathi zegwadle. I-Granite iyinto engokwemvelo enokusabalalisa kokucindezeleka kwangaphakathi okuyinkimbinkimbi. Ukusika ngomshini kungaphazamisa kalula le bhalansi ngesikhathi esifushane, okuholela ekuwohlokeni okuncane kamuva. Ukugaya ngesandla, nokho, kusebenzisa ukucindezela okuphansi nokushisa okuphansi. Ngemva kokugaya, ingcweti ivumela ucezu lokusebenza ukuba luphumule, okuvumela ukucindezelwa kwangaphakathi komsebenzi ukuthi kukhululeke ngokwemvelo ngaphambi kokuqhubeka nezilungiso. Le ndlela "ehamba kancane futhi ezinzile" iqinisekisa ukuthi inkundla igcina ukunemba okuzinzile ekusetshenzisweni kwesikhathi eside.
Ngaphezu kwalokho, ukugaya ngesandla kungakha izakhiwo ze-isotropic. Omaki bemishini bemishini bavamise ukuthi baqondise, okuholela ekukhuhlaneni okuhlukahlukene kanye nokuphindaphinda ngezindlela ezihlukene. Ukugaya okwenziwa mathupha, ngobuchule bengcweti obuvumelana nezimo, kudala ukusatshalaliswa okungahleliwe nokufana okufanayo kwamamaki okuguga, okuholela kukhwalithi yendawo engashintshi kuzo zonke izinhlangothi. Lokhu kubaluleke kakhulu kumasistimu wokulinganisa anembe kakhulu namasistimu okunyakaza.
Okubaluleke nakakhulu, i-granite yenziwe ngamaminerali ahlukahlukene, njenge-quartz, i-feldspar, ne-mica, ngayinye enokwehluka kobunzima obuhlukile. Ukugaya ngemishini kuvame ukuholela ekusikeni ngokweqile kwamaminerali athambile kanye nokuphuma kwamaminerali aqinile, okudala ukungalingani okuncane kakhulu. Ukugaya mathupha, ngakolunye uhlangothi, kuncike kokuhlangenwe nakho nomuzwa womdwebi. Bangakwazi njalo ukulungisa amandla kanye ne-engeli phakathi nenqubo yokugaya, bakhulise ibhalansi phakathi kokuhluka kwamaminerali kanye nokuzuza indawo yokusebenza efanayo nengagugi.
Ngomqondo othile, ukucutshungulwa kwezinkundla zegwadle ezinemba okuphezulu kuyi-symphony yobuchwepheshe besimanje bokulinganisa ukunemba kanye nobuciko bendabuko. Imishini ye-CNC ihlinzeka ngokusebenza kahle kanye nokuma okuyisisekelo, kuyilapho ukucaba okuphezulu, ukuzinza, nokufana kufanele kuzuzwe ngesandla. Kanjalo, yonke inkundla yegwadle esezingeni eliphezulu ihlanganisa ubuhlakani nesineke sezingcweti ezingabantu.
Kubasebenzisi abaphishekela ukunemba okuphelele, ukuqaphela inani lokugaya mathupha kusho ukukhetha into ethembekile ezokwazi ukumelana nesikhathi. Kungaphezu nje kocezu lwetshe; kuyisisekelo sokuqinisekisa ukunemba okuphelele ekukhiqizeni nasekukaleni.
