Oomatshini bokulungelelaniswa abathathu (i-CMMs) bacacisa kakhulu kwaye izixhobo ezichanekileyo ezinokulinganisa ubungakanani bejometri yento egqibeleleyo. Zisetyenziselwa kakhulu kwimizi-mveliso yokwenziwa kunye nobunjineli ukuqinisekisa ukuba iimveliso ziveliswa zihlangabezane nemigangatho echazayo. Ukufezekisa oku, kubalulekile ukuba ube nesiseko esomeleleyo nesizinzileyo apho i-CMM ingafakwa khona. IGranite yeyona nto iqhelekileyo isetyenziswayo, ngenxa yamandla ayo aphezulu, uzinzo, kunye nokuxhathisa kutshintsho lobushushu.
Ukukhetha ubungakanani obufanelekileyo kunye nobunzima besiseko seGranite yinto ebalulekileyo ekufuneka uyiqwalasele xa ukhetha i-cmm. Isiseko kufuneka sikwazi ukuxhasa i-CMM ngaphandle kokuguqula okanye ukujikeleza ngexesha lokulinganisa ukuqinisekisa iziphumo eziguqukayo nezichanekileyo. Ukwenza ukhetho olugqibeleleyo, zimbalwa izinto eziyimfuneko kufuneka zithathelwe ingqalelo, njengokuchaneka okufunekayo, ubungakanani bomatshini wokulinganisa, kunye nobunzima bezinto eziza kulinganiswa.
Okokuqala, ukuchaneka okufunekayo kommiselo kufuneka kuthathelwe ingqalelo ngelixa ukhetha ubungakanani obufanelekileyo kunye nobunzima besiseko segrani se-CMM. Ukuba ukuchaneka okuphezulu kuyafuneka, emva koko isiseko esikhulu nezethutyana esikhulu ngakumbi sikhetheke, njengoko siza kusizisela ukuzinza okukhulu kunye nokuphazamiseka okungapheliyo ngelixa kulinganiselwe. Ke, ubungakanani obufanelekileyo besiseko seGranite ikakhulu buxhomekeke kwinqanaba lokuchaneka okufunekayo kumlinganiso.
Okwesibini, ubungakanani be-CMM ngokwayo nayo ngokwayo ikwaphembelela ubungakanani obufanelekileyo kunye nobunzima besiseko seGranite. I-CMM inkulu i-CMM, inkulu enkulu yesiseko esihle kakhulu, ukuqinisekisa ukuba ibonelela ngenkxaso eyaneleyo kunye nozinzo. Umzekelo, ukuba umatshini we-CMM yimitha enye kuphela ngemitha enye, emva koko isiseko esincinci seGranite esijikeleze iikhilogres ezingama-800 sinokwanela. Nangona kunjalo, kumatshini omkhulu, njengenye yokulinganisa iimitha ezi-3 ngeemitha ezi-3, isiseko esikhulu kwaye sisekele kakhulu kwaye sisekele kakhulu.
Okokugqibela, ubunzima bezinto ezinokuthi zilinganiswe ziya kufuneka zithathelwe ingqalelo xa ukhetha ubungakanani obufanelekileyo kunye nobunzima besiseko segrani se-COMM. Ukuba izinto zinzima kakhulu, emva koko ukukhetha okungakumbi, kwaye ke uzinzo ngakumbi, isiseko seGranite kuya kuqinisekisa imilinganiselo echanekileyo. Umzekelo, ukuba izinto zinkulu kune-1,000 yeekhilogramu, emva koko isiseko seGranite sivavanya iikhilogram ezili-1,500 okanye ngaphezulu zinokufaneleka ukuqinisekisa uzinzo kunye nokuchaneka komlinganiso.
Ukuqukumbela, ukukhetha ubungakanani obufanelekileyo kunye nobunzima besiseko seGranite kubalulekile ukuqinisekisa ukuchaneka kunye nokuchaneka kwemilinganiselo ethathiweyo kwi-CMM. Kubalulekile ukuqwalasela inqanaba lokuchaneka elifunekayo, ubungakanani bomatshini we-CMM, nobunzima bezinto ezinokuthi zilinganiswe ukufumanisa ubungakanani obufanelekileyo kunye nobunzima besiseko seGranite. Ngokuqwalaselwa ngenyameko kwezi zinto, isiseko esifanelekileyo seGranite sinokukhethwa, esiya kubonelela ngenkxaso eyaneleyo, uzinzo, kunye nokuqinisekisa imilinganiselo echanekileyo ngalo lonke ixesha.
