Imishini yokulinganisa emithathu (ama-CMM) angamathuluzi anembe ngendlela emangalisayo futhi anembile akwazi ukukala izilinganiso zejiyomethri zento ngokunemba okuphezulu.Asetshenziswa kakhulu ezimbonini zokukhiqiza nezobunjiniyela ukuze kuqinisekiswe ukuthi imikhiqizo ekhiqizwayo ihlangabezana nezindinganiso eziqondile.Ukufeza lokhu, kubalulekile ukuba nesisekelo esiqinile nesizinzile lapho i-CMM ingagxunyekwa khona.I-Granite iyinto esetshenziswa kakhulu, ngenxa yamandla ayo aphezulu, ukuzinza, nokumelana nokushintsha kwezinga lokushisa.
Ukukhetha usayizi ofanelekile nesisindo sesisekelo segwadle kuyisici esibalulekile okufanele icatshangelwe lapho ukhetha i-CMM.Isisekelo kufanele sikwazi ukusekela i-CMM ngaphandle kokuguquguquka noma ukudlidliza phakathi nokulinganisa ukuze kuqinisekiswe imiphumela engaguquki nenembile.Ukuze wenze ukukhetha okuphelele, izici ezimbalwa ezibalulekile kudingeka zicatshangelwe, njengokunemba okudingekayo, ubukhulu bomshini wokulinganisa, nesisindo sezinto okufanele zikalwe.
Okokuqala, ukunemba okudingekayo kwesilinganiso kudinga ukucatshangelwa ngenkathi kukhethwa usayizi ofanelekile nesisindo sesisekelo segwadle se-CMM.Uma kudingeka ukunemba okuphezulu, khona-ke isisekelo se-granite esikhulu kakhulu nesibaluleke kakhulu siyathandeka, njengoba sizonikeza ukuzinza okukhulu kanye nokuphazamiseka okuncane kokudlidliza ngenkathi kulinganiswa.Ngakho-ke, usayizi ofanele wesisekelo se-granite uncike kakhulu ezingeni lokunemba elidingekayo ukuze kukale.
Okwesibili, ubukhulu be-CMM ngokwayo buphinde buthinte ubukhulu obufanele nesisindo sesisekelo se-granite.Uma i-CMM inkulu, isisekelo se-granite kufanele sibe sikhulu, ukuze kuqinisekiswe ukuthi inikeza ukusekelwa okwanele nokuzinza.Isibonelo, uma umshini we-CMM uyimitha elingu-1 kuphela ngemitha elingu-1, khona-ke isisekelo esincane segwadle esinesisindo esingamakhilogremu angu-800 singase sanele.Kodwa-ke, emshinini omkhulu, ofana nowokulinganisa amamitha angu-3 ngamamitha angu-3, isisekelo segwadle esikhulu ngokuhambisanayo sizodingeka ukuze kuqinisekiswe ukuzinza komshini.
Okokugcina, isisindo sezinto ezizokalwa sizodinga ukucatshangelwa lapho kukhethwa usayizi ofanelekile nesisindo sesisekelo segwadle se-CMM.Uma izinto zinzima kakhulu, bese ukhetha isisekelo esikhulu, futhi esizinzile, isisekelo se-granite sizoqinisekisa izilinganiso ezinembile.Isibonelo, uma izinto zizinkulu kunamakhilogremu angu-1,000, isisekelo se-granite esinesisindo esingamakhilogremu angu-1,500 noma ngaphezulu singase sifaneleke ukuze kuqinisekiswe ukuzinza nokunemba kwesilinganiso.
Sengiphetha, ukukhetha usayizi ofanelekile nesisindo sesisekelo segwadle kubalulekile ukuze kuqinisekiswe ukunemba nokunemba kwezilinganiso ezithathwe ku-CMM.Kubalulekile ukucabangela izinga lokunemba elidingekayo, usayizi womshini we-CMM, nesisindo sezinto okufanele zikalwe ukuze kunqunywe usayizi ofanele nesisindo sesisekelo segwadle.Ngokucatshangelwa ngokucophelela kwalezi zici, isisekelo se-granite esiphelele singakhethwa, esizohlinzeka ngokusekela okwanele, ukuzinza, nokuqinisekisa izilinganiso ezinembile ngaso sonke isikhathi.
