Iqonga lokuvavanya i-granite echanekileyo sisiseko sokulinganisa okuphindaphindiweyo nokuchanekileyo. Ngaphambi kokuba nasiphi na isixhobo se-granite—ukusuka kwipleyiti elula yomphezulu ukuya kwisikwere esintsonkothileyo—sithathwe njengesifanelekileyo ukusetyenziswa, ukuchaneka kwaso kufuneka kuqinisekiswe ngokungqongqo. Abavelisi abanjengoZHONGHUI Group (ZHHIMG) balandela imigangatho yokulawula umgangatho engqongqo, beqinisekisa amaqonga kuwo onke amanqanaba anje ngo-000, 00, 0, kunye no-1. Esi siqinisekiso sixhomekeke kwiindlela zobugcisa ezimiselweyo ezichaza ubucaba bokwenyani bomphezulu.
Ukuchonga Ubungangamsha: Iindlela Eziphambili
Injongo ephambili yokuqinisekisa iqonga legranite kukufumanisa impazamo yalo yokuba tyaba (FE). Le mpazamo ichazwa ngokusisiseko njengomgama omncinci phakathi kweenqwelo-moya ezimbini ezihambelanayo eziqulathe zonke iindawo zomphezulu wokusebenza. Iingcali zeMetro zisebenzisa iindlela ezine ezivunyiweyo ukufumanisa eli xabiso:
Iindlela ze-Three-Point kunye ne-Diagonal: Ezi ndlela zibonelela ngovavanyo olusebenzayo nolusisiseko lwe-topography yomphezulu. Indlela ye-Three-Point iseka i-avaluation reference plane ngokukhetha amanqaku amathathu ahlukeneyo kakhulu kumphezulu, ichaza i-FE ngomgama ophakathi kwe-enclosing two parallel planes. Indlela ye-Diagonal, edla ngokusetyenziswa njengomgangatho weshishini, idla ngokusebenzisa izixhobo ezintsonkothileyo ezifana ne-electronic level kunye ne-bridge plate. Apha, i-reference plane ibekwe kwi-diagonal, enika indlela esebenzayo yokubamba usasazo lweempazamo lulonke kumphezulu wonke.
Indlela Encinci Yokuphindaphinda Ezimbini (Izikwere Ezincinci): Le yindlela engqongqo kakhulu ngokwezibalo. Ichaza iplani yokubhekisa njengeyona inciphisa isimbuku sezikwere zemigama ukusuka kuzo zonke iindawo ezilinganisiweyo ukuya kwiplani ngokwayo. Le ndlela yezibalo inika uvavanyo oluchanekileyo lokuthamba kodwa ifuna ukucutshungulwa kwekhompyutha okuphambili ngenxa yobunzima bezibalo ezibandakanyekayo.
Indlela yeNdawo encinci: Le ndlela ihambelana ngqo nenkcazo yejometri yobucaba, apho ixabiso lempazamo limiselwa bububanzi bendawo encinci efunekayo ukugubungela onke amanqaku omphezulu alinganisiweyo.
Ubuchule bokuHlanganisa: I-Protocol yeSibonisi seDial
Ngaphandle kokuba tyaba okuqhelekileyo, izixhobo ezikhethekileyo ezifana nezikwere zegranite zifuna ukuqinisekiswa kokufana phakathi kobuso bazo obusebenzayo. Indlela yesalathisi se-dial ifanelekile kakhulu kulo msebenzi, kodwa ukuthembeka kwayo kuxhomekeke ngokupheleleyo ekusebenzeni ngononophelo.
Uhlolo kufuneka luhlale lwenziwa kwipleyiti yomphezulu wereferensi echanekileyo kakhulu, kusetyenziswa ubuso obunye bokulinganisa besikwere segranite njengereferensi yokuqala, elungelelaniswe ngononophelo kwiqonga. Inyathelo elibalulekileyo kukumisela iindawo zokulinganisa ebusweni obujongwayo—ezi azicwangciswanga. Ukuqinisekisa uvavanyo olupheleleyo, indawo yokujonga imiselwe malunga ne-5mm ukusuka kumda womphezulu, incediswa yipateni yegridi ebekwe ngokulinganayo phakathi, kunye neendawo ezahlulwe rhoqo yi-20mm ukuya kwi-50mm. Le gridi iqinileyo iqinisekisa ukuba yonke i-contour idweliswe ngendlela ecwangcisiweyo yisalathisi.
Okubalulekileyo kukuba, xa uhlola ubuso obuchaseneyo, isikwere segranite kufuneka sijikeleziswe ngama-degrees ali-180. Olu tshintsho lufuna unonophelo olukhulu. Isixhobo akufuneki sityibilikiswe kwipleyiti yokubhekisa; kufuneka siphakanyiswe ngononophelo kwaye sibekwe kwakhona. Le protocol yokuphatha ebalulekileyo ithintela ukudibana okurhabaxa phakathi kweendawo ezimbini ezidibeneyo ngokuchanekileyo, ikhusela ukuchaneka okufunyenwe nzima kwesikwere kunye neqonga lokubhekisa ixesha elide.
Ukufikelela kunyamezelo oluqinileyo lwezixhobo ezikumgangatho ophezulu—njengezikwere ze-ZHHIMG zeGrade 00 ezichanekileyo—bubungqina beempawu zomzimba eziphezulu zomthombo wegranite kunye nokusetyenziswa kwezi protocol zemetrology eziqinileyo nezimiselweyo.
