Imishini yokulinganisa yokulinganisa ezintathu (CMMS) iyithuluzi elinembile kakhulu futhi elinembile elingalinganisa ubukhulu bejometri yento enokunemba okuphezulu. Zisetshenziswa kakhulu ezimbonini zokukhiqiza nezobunjiniyela ukuze kuqinisekiswe ukuthi imikhiqizo ekhiqizwa amazinga aqondile. Ukufeza lokhu, kubalulekile ukuba nesisekelo esiqinile nesinzinzile lapho i-CMM ingafakwa khona. I-Granite iyinto evame kakhulu esetshenziswayo, ngenxa yamandla ayo aphezulu, ukuqina, kanye nokumelana nezinguquko zokushisa.
Ukukhetha usayizi ofanele nesisindo sesisekelo se-granite kuyinto ebucayi okufanele uyicabangele lapho ukhetha i-CMM. Isisekelo kumele sikwazi ukuxhasa i-CMM ngaphandle kokuguquguquka noma ukudlidliza ngesikhathi sokulinganisa ukuqinisekisa imiphumela engaguquki futhi enembile. Ukwenza ukukhetha okuhle, izici ezimbalwa ezibalulekile ezidinga ukubhekwa, njengokunemba okudingekayo, usayizi womshini wokulinganisa, kanye nesisindo sezinto okufanele zilinganiswe.
Okokuqala, ukunemba okudingekayo kwesilinganiso kudinga ukubhekwa ngenkathi ukhetha usayizi ofanele nesisindo sesisekelo se-granite se-CMM. Uma kudingeka ukunemba okuphezulu, khona-ke isisekelo esikhulu sama-granite futhi esiphakeme kakhulu se-granite sincono, ngoba sizohlinzeka ngozolwazi olukhulu kakhulu kanye nokuphazamiseka okuncane ngenkathi kulinganiswa. Ngakho-ke, usayizi ofanele wesisekelo se-granite ikakhulukazi kuncike ezingeni lokunemba elidingekayo ukuze kulinganiswe.
Okwesibili, ubukhulu be-CMM uqobo buthonya ngosayizi ofanele nesisindo sesisekelo se-granite. I-CMM enkulu yi-CMM, ubukhulu besisekelo se-granite kufanele kube, ukuqinisekisa ukuthi inikeza ukwesekwa okwanele nokuqina. Isibonelo, uma umshini we-CMM unemitha elilodwa kuphela ngemitha eyi-1, bese isisekelo esincane samagreni esinesisindo esingamakhilogremu angama-800 singase sikwanele. Kodwa-ke, ngomshini omkhulu, njengokulinganisa okukodwa amamitha ama-3 ngamamitha amathathu, kuzodingeka isisekelo esikhulu sama-granite futhi esinamandla sokuqinisekisa ukuqina komshini.
Okokugcina, isisindo sezinto okufanele zilinganiswe kuzodingeka ukuthi kubhekwe lapho ukhetha usayizi ofanele nesisindo sesisekelo se-granite se-CMM. Uma izinto zisinda ikakhulukazi, bese zikhetha okubaluleke kakhulu, futhi ngenxa yalokho zizinzile, isisekelo segreni zizoqinisekisa ukukalwa okunembile. Isibonelo, uma izinto zikhulu kunamakhilogremu ayi-1 000, bese kuba isisekelo se-granite esinesisindo esingu-1,500 amakhilogremu noma ngaphezulu kungahle kufanelekile ukuqiniseka ukuqina nokunemba kwesilinganiso.
Ekuphetheni, ukukhetha usayizi ofanele nesisindo sesisekelo segranite kubalulekile ukuqinisekisa ukunemba nokunemba kwezilinganiso ezithathwe ku-cmm. Kubalulekile ukucubungula izinga elidingekayo lokunemba, usayizi womshini we-CMM, kanye nesisindo sezinto okufanele zilinganiswe ukuthola usayizi ofanele nesisindo sesisekelo se-granite. Ngokucabanga ngokucophelela ngalezi zinto, isisekelo se-granite esifanele singakhethwa, esizonikeza ukwesekwa okwanele, ukuqina, futhi kuqinisekiswe izilinganiso ezinembile ngaso sonke isikhathi.
