Ngaba ibhedi yegranite ibalulekile xa ukhetha umatshini wokulinganisa i-bridge coordinate?

Umatshini wokulinganisa i-bridge coordinate (CMM) lutyalo-mali olubalulekileyo kulo naliphi na ishishini lokuvelisa njengoko lunceda ukuqinisekisa ukuba iimveliso eziveliswayo ziyahlangabezana neemfuno kunye nemigangatho efunekayo. Xa ukhetha i-bridge CMM, kufuneka kuqwalaselwe izinto ezahlukeneyo, kwaye enye yezona zinto zibalulekileyo luhlobo lwezinto zebhedi eziza kusetyenziswa. Ibhedi yegranite lukhetho oludumileyo kwii-bridge CMM ezininzi, kwaye eli nqaku liza kuxoxa ngesizathu sokuba iibhedi zegranite zibalulekile kwinkqubo yokukhetha.

I-Granite luhlobo lwelitye eliyi-igneous elenziwe ngokuqiniswa kancinci kwe-magma phantsi komphezulu woMhlaba. Eli litye laziwa ngokuqina kwalo, ubulukhuni, kunye nokumelana nokuguguleka, okwenza libe yinto efanelekileyo yokwakha iibhedi ze-CMM. I-Granite izinzile kakhulu ngobukhulu, oko kuthetha ukuba inokugcina imo kunye nobukhulu bayo nokuba iphantsi kotshintsho lobushushu kunye nokufuma. Ukongeza, i-granite inomlinganiselo ophantsi wokwanda kobushushu, okwenza ibe yinto efanelekileyo yokunciphisa ukukhula kobushushu ngexesha lokulinganisa.

Esinye isizathu sokuba iibhedi zegranite zidume kakhulu kwiibridge CMMs kungenxa yokuba zinamandla aphezulu okufunxa. Ukufunxa kubhekisa kumandla ezinto zokufunxa ukungcangcazela nokunciphisa ingxolo. Amandla aphezulu okufunxa igranite anceda ekunciphiseni ukungcangcazela kunye nengxolo eveliswa ngexesha lokulinganisa, ngaloo ndlela kuphucula ukuchaneka kokulinganisa kunye nokuphindaphinda. Ukongeza, igranite ine-conductivity ephantsi yombane, enceda ukunciphisa umngcipheko wokuphazamiseka kombane ngexesha lokulinganisa, okwandisa ukuthembeka kokulinganisa komatshini.

I-granite esetyenziswa ekwakhiweni kweebhulorho ze-CMMs idla ngokuba semgangathweni ophezulu, nto leyo enceda ekuphuculeni ukuchaneka kunye nobude benkqubo. Oku kungenxa yokuba i-granite iyagrunjwa, ipolishwe, kwaye igqitywe ngokwemigangatho ethile ukuqinisekisa ukuba inomphezulu othe tyaba nofanayo. Ukuthe tyaba kwebhedi ye-granite yinto ebalulekileyo kuba ibonelela ngomphezulu ozinzileyo apho i-probe ihamba khona ngexesha lokulinganisa. Ukongeza, ukufana kwebhedi ye-granite kuqinisekisa ukuba akukho tshintsho okanye ukuphazamiseka okuncinci kwindawo yokulinganisa, okukhokelela ekulinganisweni okuchanekileyo nokuphindaphindiweyo.

Ngamafutshane, ukukhetha i-CMM yebhulorho enebhedi yegranite yinto ebalulekileyo ekufuneka iqwalaselwe ngenxa yeenzuzo ezininzi ezibonelelayo. Ibhedi yegranite inika uzinzo oluphezulu, i-coefficient ephantsi yokwandiswa kobushushu, amandla aphezulu okudambisa, umbane ophantsi, kunye nokugqitywa komphezulu okumgangatho ophezulu. Zonke ezi zinto zinegalelo ekuchanekeni, ukuphindaphindeka, kunye nobude benkqubo. Ke ngoko, xa ukhetha i-CMM yebhulorho, qinisekisa ukuba ibhedi yegranite iyahlangabezana nemigangatho efunekayo kunye neenkcukacha ukuze kufezekiswe iziphumo zokulinganisa ezifanelekileyo.
