Xa kufikwa ekukhetheni isiseko segranite somatshini wokulinganisa i-coordinate (CMM), kukho iinkcukacha zobugcisa kunye neeparameter ezininzi ekufuneka ziqwalaselwe ukuqinisekisa ukuchaneka nokuthembeka kokulinganisa. Kweli nqaku, siza kuxoxa ngezinye zezi zinto kunye nokubaluleka kwazo kwinkqubo yokukhetha.
1. Umgangatho wezinto: I-Granite yenye yezona zinto zidumileyo kwisiseko se-CMM ngenxa yokuqina kwayo okuphezulu, i-coefficient ephantsi yokwandiswa kobushushu, kunye nokukwazi kwayo ukudambisa kakuhle. Nangona kunjalo, ayizizo zonke iintlobo ze-granite ezifanelekileyo kule njongo. Umgangatho we-granite osetyenziselwa isiseko se-CMM kufuneka ube phezulu, ube neziphene ezincinci okanye ubuthathaka, ukuqinisekisa umlinganiselo ozinzileyo nochanekileyo.
2. Uzinzo: Enye into ebalulekileyo ekufuneka iqwalaselwe xa ukhetha isiseko segranite se-CMM kukuzinza kwaso. Isiseko kufuneka sibe nokuphambuka okuncinci okanye ukuguqulwa okuncinci phantsi komthwalo, ukuqinisekisa ukulinganiswa okuchanekileyo nokuphindaphindwayo. Uzinzo lwesiseko lukwachaphazeleka ngumgangatho womphezulu oxhasayo kunye nenqanaba lesiseko somatshini.
3. Ukuthe tyaba: Ukuthe tyaba kwesiseko segranite kubalulekile ekuchanekeni kokulinganisa. Isiseko kufuneka senziwe ngokuchanekileyo kwaye kufuneka sihlangabezane nokunyamezela ukuthe tyaba okuchaziweyo. Ukuthe tyaba ukusuka ekuthe tyaba kunokubangela iimpazamo zokulinganisa, kwaye i-CMM kufuneka ilinganiswe rhoqo ukuze kulungiswe ezo ziphambuko.
4. Ukugqitywa komphezulu: Ukugqitywa komphezulu wesiseko segranite kubalulekile ekuqinisekiseni ukuchaneka kokulinganisa. Umphezulu orhabaxa unokubangela ukuba iprobe itsibe okanye inamathele, ngelixa umphezulu ogudileyo uqinisekisa amava angcono okulinganisa. Ke ngoko, ukugqitywa komphezulu kufuneka kukhethwe ngokweemfuno zesicelo.
5. Ubungakanani kunye nobunzima: Ubungakanani kunye nobunzima besiseko segranite buxhomekeke kubungakanani kunye nobunzima bomatshini weCMM. Ngokubanzi, isiseko esinzima nesikhudlwana sinika uzinzo olungcono kunye nokuchaneka kodwa sifuna isakhiwo esixhasayo esomeleleyo kunye nesiseko. Ubungakanani besiseko kufuneka bukhethwe ngokusekelwe kubukhulu besixhobo somsebenzi kunye nokufikeleleka kwendawo yokulinganisa.
6. Iimeko Zokusingqongileyo: Isiseko segranite, njengayo nayiphi na enye inxalenye yomatshini weCMM, sichaphazeleka ziimeko zokusingqongileyo ezifana nobushushu, ukufuma, kunye nokungcangcazela. Isiseko segranite kufuneka sikhethwe ngokusekelwe kwiimeko zokusingqongileyo zendawo yokulinganisa kwaye kufuneka sahlulwe kuyo nayiphi na imithombo yokungcangcazela okanye yokutshintsha kobushushu.
Ukuqukumbela, ukukhethwa kwesiseko segranite kumatshini weCMM kufuna ukuqwalaselwa ngononophelo kweenkcukacha zobugcisa kunye neeparamitha ezininzi ukuqinisekisa ukulinganiswa okuchanekileyo nokuthembekileyo. Umgangatho wezinto ezisisiseko, ukuzinza, ukuthamba, ukugqitywa komphezulu, ubungakanani, kunye nobunzima, kunye neemeko zokusingqongileyo zonke zizinto ezibalulekileyo ekufuneka ziqwalaselwe ngexesha lenkqubo yokukhetha. Ngokukhetha isiseko segranite esifanelekileyo, umatshini weCMM unokubonelela ngokulinganisa okuchanekileyo nokuthembekileyo, okukhokelela ekuphuculweni komgangatho wemveliso kunye nokwaneliseka kwabathengi.
