Uma kukhulunywa ngokuthenga i-Coordinate Measuring Machine (CMM), ukukhetha isisekelo se-granite esifanele kubalulekile. Isisekelo se-granite siyisisekelo sesistimu yokulinganisa futhi ikhwalithi yaso ingathinta kakhulu ukunemba kwezilinganiso. Ngakho-ke, kubalulekile ukukhetha isisekelo se-granite se-CMM esifanele esihlangabezana nezidingo ezithile zesicelo sakho sokulinganisa.
Nazi ezinye izinto okufanele uzicabangele lapho ukhetha isisekelo se-granite se-CMM esifanele:
1. Usayizi nesisindo: Usayizi nesisindo sesisekelo se-granite kufanele kukhethwe ngokusekelwe kusayizi nesisindo sezingxenye ezizolinganiswa. Isisekelo kufanele sibe sikhulu futhi sibe nesisindo esanele ukunikeza ukuzinza nokunciphisa ukudlidliza okungathinta ukunemba kokulinganisa.
2. Ukuthamba kanye nokulingana: Isisekelo segranite kufanele sibe nezinga eliphezulu lokuthamba kanye nokulingana ukuqinisekisa ukuthi i-CMM ingahamba ngendlela eqondile nebushelelezi ngesikhathi sokulinganisa. Ukuthamba kanye nokulingana kufanele kuchazwe ngezinga elifanele izidingo zakho zokulinganisa.
3. Ikhwalithi yezinto ezibonakalayo: Ikhwalithi yezinto ezenziwe nge-granite ezisetshenziselwa isisekelo nayo ibalulekile. I-granite esezingeni eliphezulu izoba nokungapheleli okuncane okungathinta ukunemba kokulinganisa. I-granite kufanele futhi ibe ne-coefficient ephansi yokwanda kokushisa ukuze kuncishiswe izinguquko zobukhulu ngenxa yokushintshashintsha kwezinga lokushisa.
4. Ukuqina: Ukuqina kwesisekelo se-granite kungenye into ebalulekile okufanele icatshangelwe. Isisekelo kufanele sikwazi ukusekela isisindo se-CMM nanoma yiziphi izingxenye ezengeziwe ngaphandle kokugoba noma ukugoba, okungathinta ukunemba kokulinganisa.
5. Ukuphela kobuso: Ukuphela kobuso besisekelo se-granite kufanele kukhethwe ngokusekelwe ekusetshenzisweni kokulinganisa. Isibonelo, ukuqeda kobuso okubushelelezi kungadingeka ukuze kulinganiswe ngokunemba okuphezulu, kanti ukuqeda okuqinile kungafaneleka ukuze kulinganiswe okungabalulekile kangako.
6. Intengo: Okokugcina, intengo yesisekelo se-granite nayo iyinto okufanele icatshangelwe. I-granite esezingeni eliphezulu kanye nosayizi omkhulu ngokuvamile kuzobiza kakhulu. Kodwa-ke, kubalulekile ukukhetha isisekelo esinikeza izinga elidingekayo lokunemba kwezidingo zakho zokulinganisa, kunokukhetha nje inketho eshibhile.
Ngamafuphi, ukukhetha isisekelo se-granite se-CMM esifanele kudinga ukucatshangelwa ngokucophelela usayizi, ukuthamba kanye nokulingana, ikhwalithi yezinto ezibonakalayo, ukuqina, ukuqeda ubuso, kanye nentengo. Ngokucabangela lezi zici, ungaqinisekisa ukuthi isisekelo se-granite sinikeza isisekelo esizinzile nesinembile sesistimu yakho yokulinganisa.
