Yiziphi izici ezibalulekile ezithinta ukunemba kokulinganisa okuphelele kwe-CMM?

I-Granite iyinto evame ukusetshenziswa ezakhiweni zomshini wokulinganisa ohlangene (i-CMM) ngenxa yokuqina kwayo okuhle kakhulu kanye nokumelana nokushintshashintsha kwezinga lokushisa. Ukunemba kokulinganisa okuphelele kwe-CMM kuthinteka yizici eziningana ezibalulekile, futhi ukukhetha i-granite njengezinto zokwakha kudlala indima ebalulekile ekuqinisekiseni ukulinganisa okunembile nokuthembekile.

Esinye sezici ezibalulekile ezithinta ukunemba kokulinganisa okuphelele kwe-CMM ukuqina kwesakhiwo somshini. I-Granite inobukhulu obuphezulu kanye ne-coefficient ephansi yokwanda kokushisa, okunikeza isisekelo esiqinile nesiqinile sama-CMM. Lokhu kuzinza kunciphisa imiphumela yokudlidliza kanye nezinguquko zokushisa ezingathinta ukunemba kokulinganisa. Ngaphezu kwalokho, izakhiwo zemvelo zokunciphisa umswakama ze-granite zisiza ekunciphiseni umthelela wokuphazamiseka kwangaphandle, okuthuthukisa kakhulu ukunemba kokulinganisa.

Esinye isici esibalulekile ukuzinza kobukhulu bezingxenye ze-CMM. I-Granite ikhombisa izinguquko ezincane zobukhulu ngokuhamba kwesikhathi, okuqinisekisa ukuthi umshini ugcina ukunemba kwawo kanye nokuphindaphindeka kwawo isikhathi eside sokusetshenziswa. Lokhu kubalulekile ezinhlelweni zokusebenza ezidinga ukulinganiswa okulinganayo nokuthembekile.

Ikhwalithi yobuso begranite esetshenziswa ekwakhiweni kwe-CMM nayo idlala indima ebalulekile ekunembeni kokulinganisa. Izindawo ezibushelelezi nezisicaba zibalulekile ekufakweni okufanele kwezinhlelo zokulinganisa kanye nezinto zokulungisa, kanye nokuhamba kwezimbazo zomshini. Ubuso begranite obusezingeni eliphezulu bunegalelo ekunembeni okuphelele kwe-CMM.

Ngaphezu kwalokho, ukwakheka nokukhiqizwa kwezingxenye ze-CMM njengemijikelezo yokuqondisa kanye nama-air bearings kungathinta ukunemba kokulinganisa okuphelele. Ukuqondanisa kahle kanye nokulinganiswa kwalezi zingxenye, kanye nokuqina okunikezwa yisisekelo se-granite, kubalulekile ekufinyeleleni izilinganiso ezinembile neziphindaphindwayo.

Ngamafuphi, ukukhethwa kwe-granite njengezinto zokwakha ze-CMM kuyisici esibalulekile ekuqinisekiseni ukunemba okuphezulu kokulinganisa. Ukuqina kwayo, ukuqina kobukhulu, ikhwalithi yobuso kanye nezakhiwo zokudambisa konke kunegalelo ekunembeni nasekuthembekeni komshini. Uma kuhlanganiswa nezingxenye eziklanywe ngokucophelela futhi ezilinganisiwe, i-granite idlala indima ebalulekile ekufezeni izilinganiso ezinembile ezinhlobonhlobo zezicelo zezimboni kanye ne-metrology.
