Uma kukhulunywa ngokukhetha isisekelo se-granite somshini wokulinganisa ohlanganisiwe (i-CMM), kunezincazelo zobuchwepheshe eziningana kanye nemingcele okufanele icatshangelwe ukuqinisekisa ukunemba nokuthembeka kwezilinganiso. Kulesi sihloko, sizoxoxa ngezinye zalezi zici kanye nokubaluleka kwazo enkambisweni yokukhetha.
1. Ikhwalithi Yezinto Ezisetshenziswayo: I-Granite ingenye yezinto ezithandwa kakhulu zesisekelo se-CMM ngenxa yokuqina kwayo okuphezulu, i-coefficient yokukhulisa ukushisa okuphansi, kanye nekhono elihle lokudambisa. Kodwa-ke, akuzona zonke izinhlobo ze-granite ezifanele le njongo. Ikhwalithi ye-granite esetshenziselwa isisekelo se-CMM kufanele ibe phezulu, ibe namaphutha amancane noma ama-porosity, ukuqinisekisa ukulinganiswa okuzinzile nokunembile.
2. Ukuqina: Esinye isici esibalulekile okufanele usicabangele lapho ukhetha isisekelo se-granite se-CMM ukuqina kwaso. Isisekelo kufanele sibe nokuphambuka okuncane noma ukuguqulwa ngaphansi komthwalo, ukuqinisekisa ukulinganiswa okunembile nokuphindaphindwayo. Ukuqina kwesisekelo nakho kuthinteka yikhwalithi yendawo esekelayo kanye nezinga lesisekelo somshini.
3. Ukuthamba: Ukuthamba kwesisekelo se-granite kubalulekile ekulinganisweni okunembile. Isisekelo kufanele senziwe ngokunemba okuphezulu futhi kumele sihlangabezane nokubekezelela ukuthamba okucacisiwe. Ukuphambuka ekuthambatheni kungabangela amaphutha okulinganisa, futhi i-CMM kufanele ilinganiswe ngezikhathi ezithile ukuze kulungiswe ukuphambuka okunjalo.
4. Ukuphela Komphezulu: Ukuphela komphezulu wesisekelo se-granite nakho kubalulekile ekuqinisekiseni ukunemba kokulinganisa. Indawo elukhuni ingabangela ukuthi i-probe yeqe noma inamathele, kuyilapho indawo ebushelelezi iqinisekisa ulwazi olungcono lokulinganisa. Ngakho-ke, ukuqeda komphezulu kufanele kukhethwe ngokuya ngezidingo zohlelo lokusebenza.
5. Usayizi Nesisindo: Usayizi nesisindo sesisekelo se-granite kuncike kusayizi nesisindo somshini we-CMM. Ngokuvamile, isisekelo esinzima nesikhudlwana sinikeza ukuzinza nokunemba okungcono kodwa sidinga isakhiwo sokusekela esiqinile kanye nesisekelo. Usayizi wesisekelo kufanele ukhethwe ngokusekelwe kusayizi wento yokusebenza kanye nokufinyeleleka kwendawo yokulinganisa.
6. Izimo Zemvelo: Isisekelo se-granite, njenganoma iyiphi enye ingxenye yomshini we-CMM, sithinteka yizimo zezemvelo ezifana nokushisa, umswakama, kanye nokudlidliza. Isisekelo se-granite kufanele sikhethwe ngokusekelwe ezimweni zezemvelo zendawo yokulinganisa futhi kufanele sihlukaniswe nanoma yimiphi imithombo yokudlidliza noma ukushintsha kwezinga lokushisa.
Ekuphetheni, ukukhethwa kwesisekelo se-granite somshini we-CMM kudinga ukucatshangelwa ngokucophelela kwemininingwane eminingi yobuchwepheshe kanye nemingcele ukuqinisekisa ukulinganiswa okunembile nokuthembekile. Ikhwalithi yezinto eziyisisekelo, ukuzinza, ukuba yisicaba, ukuqeda ubuso, usayizi, nesisindo, kanye nezimo zemvelo konke kuyizinto ezibalulekile okufanele zicatshangelwe ngesikhathi senqubo yokukhetha. Ngokukhetha isisekelo se-granite esifanele, umshini we-CMM unganikeza ukulinganisa okunembile nokuthembekile, okuholela ekuthuthukisweni kwekhwalithi yomkhiqizo kanye nokwaneliseka kwamakhasimende.
