Uma kuziwa ekukhetheni isisekelo se-granite somshini wokulinganisa wokuxhumanisa (CMM), kunezicaciso eziningana zobuchwepheshe kanye nemingcele okufanele icatshangelwe ukuze kuqinisekiswe ukunemba nokuthembeka kwezilinganiso.Kulesi sihloko, sizoxoxa ngezinye zalezi zici kanye nokubaluleka kwazo enqubweni yokukhetha.
1. Ikhwalithi Yezinto Ezibalulekile: I-Granite ingenye yezinto ezithandwa kakhulu zesisekelo se-CMM ngenxa yokuqina kwayo okuphezulu, i-coefficient ephansi yokwandisa okushisayo, kanye nekhono elihle kakhulu lokudambisa.Nokho, akuzona zonke izinhlobo zegwadle ezifanele le njongo.Izinga le-granite elisetshenziselwa isisekelo se-CMM kufanele libe phezulu, libe namaphutha amancane noma i-porosity, ukuze kuqinisekiswe izilinganiso ezinzile nezinembile.
2. Ukuzinza: Esinye isici esibalulekile okufanele icatshangelwe lapho ukhetha isisekelo se-granite se-CMM ukuzinza kwayo.Isisekelo kufanele sibe nokuchezuka okuncane noma ukuwohloka ngaphansi komthwalo, ukuze kuqinisekiswe izilinganiso ezinembile neziphindaphindekayo.Ukuzinza kwesisekelo nakho kuthinteka yikhwalithi yendawo esekelayo kanye nezinga lesisekelo somshini.
3. Ukucaba: Ukucaba kwesisekelo segwadle kubalulekile ekunembeni kokulinganisa.Isisekelo kufanele senziwe ngokunemba okuphezulu futhi kufanele sihlangabezane nokubekezelelana okucacisiwe kwe-flatness.Ukuchezuka kokuthi flatness kungabangela amaphutha okulinganisa, futhi i-CMM kufanele ilinganiswe ngezikhathi ezithile ukuze inxephezele lokho kuchezuka.
4. I-Surface Finish: Ukuqedwa okungaphezulu kwesisekelo se-granite nakho kubalulekile ekuqinisekiseni ukunemba kwezilinganiso.Indawo emangelengele ingabangela ukuthi i-probe yeqe noma inamathele, kuyilapho indawo ebushelelezi iqinisekisa ukuzizwisa kokulinganisa okungcono.Ngakho-ke, ukuphela kwendawo kufanele kukhethwe ngokuvumelana nezidingo zohlelo lokusebenza.
5. Usayizi Nesisindo: Usayizi nesisindo sesisekelo se-granite sincike kusayizi nesisindo somshini we-CMM.Ngokuvamile, isisekelo esindayo nesikhudlwana sinikeza ukuzinza nokunemba okungcono kodwa sidinga isakhiwo esiqinile sokusekela nesisekelo.Usayizi wesisekelo kufanele ukhethwe ngokusekelwe kusayizi we-workpiece kanye nokufinyeleleka kwendawo yokulinganisa.
6. Izimo Zemvelo: Isisekelo segwadle, njenganoma iyiphi enye ingxenye yomshini we-CMM, sithintwa izimo zemvelo ezifana nezinga lokushisa, umswakama, nokudlidliza.Isisekelo se-granite kufanele sikhethwe ngokusekelwe ezimweni zemvelo zendawo yokulinganisa futhi kufanele ihlukaniswe nanoma yimiphi imithombo yokudlidliza noma ukushintsha kwezinga lokushisa.
Ekuphetheni, ukukhethwa kwesisekelo se-granite somshini we-CMM kudinga ukucatshangelwa ngokucophelela kwemininingwane eminingi yobuchwepheshe kanye nemingcele ukuze kuqinisekiswe izilinganiso ezinembile nezithembekile.Ikhwalithi yezinto eziyisisekelo, ukuzinza, ukucaba, ukuphela kwendawo, usayizi, nesisindo, kanye nezimo zemvelo yizo zonke izici ezibalulekile okufanele zicatshangelwe phakathi nenqubo yokukhetha.Ngokukhetha isisekelo se-granite esifanele, umshini we-CMM unganikeza izilinganiso ezinembile nezithembekile, okuholela ekuthuthukisweni kwekhwalithi yomkhiqizo nokwaneliseka kwamakhasimende.
