Ukuthenga ipleyiti yomphezulu wegranite echanekileyo akuyonto nje yokukhetha ubungakanani kunye nomgangatho wokunyamezelana. Kwiinjineli ezininzi, abaphathi bomgangatho, kunye neengcali zokuthenga, umceli mngeni wokwenene usekuqinisekiseni ukuba ukuchaneka kweqonga legranite okufunwayo kuyahlangabezana neemfuno zobugcisa. Kwimizi-mveliso echanekileyo, i-metrology, kunye namashishini anxulumene ne-semiconductor, ipleyiti yomphezulu wegranite idla ngokuba sisalathiso esisisiseko. Ukuba ukuchaneka kwayo akuqinisekanga, yonke inkqubo yokulinganisa okanye yokuhlanganisa elandelayo iyathandabuzeka.
Ukuchaneka kwiipleyiti yomphezulu wegranite echanekileyoayisiyongcinga engabonakaliyo. Ichazwa, ilinganiswe, kwaye iqinisekiswe ngemigangatho eyaziwayo kunye neendlela zokuhlola ezilandelekayo. Xa kuvavanywa amabango omthengisi, abathengi kufuneka bagxile kakhulu kulwimi lokuthengisa kodwa bagxile ngakumbi kubungqina obungakhethi cala obubonisa indlela iqonga elilinganiswe ngayo, phantsi kweziphi iimeko, kwaye zeziphi izixhobo.
Eyona nto ibalulekileyo ebonisa ukubaiqonga lokuchaneka kwegraniteihlangabezana neemfuno zokuchaneka yingxelo yayo yokuhlolwa kobucaba. Olu xwebhu kufuneka luchaze ngokucacileyo ixabiso lobucaba obulinganisiweyo, indlela yokulinganisa esetyenzisiweyo, umgangatho wesalathiso osetyenzisiweyo, kunye neemeko zokusingqongileyo ngexesha lokuhlolwa. Amaxabiso obucaba ngaphandle komxholo anikeli ntsingiselo ingako yobugcisa. Ingxelo ethembekileyo ichaza ukuba iqonga liyahambelana na nemigangatho eyaziwayo kwihlabathi liphela efana ne-DIN, i-ASME, i-JIS, okanye iinkcukacha ezifanayo zelizwe. Le migangatho ayichazi kuphela imida yobucaba eyamkelekileyo kodwa ikwachaza nendlela ekufuneka kwenziwe ngayo imilinganiselo ukuqinisekisa ukuhambelana nokuthelekisa.
Okubaluleke ngokufanayo kukulandeleka. Ingxelo yohlolo ethembekileyo kufuneka iqinisekise ukuba izixhobo zokulinganisa ezisetyenzisiweyo zilinganisiwe kwaye ziyalandeleka kwiziko lemetrology elivunyiweyo likazwelonke okanye kwihlabathi liphela. Oku kulandeleka kuqinisekisa ukuba ukuchaneka okuxeliweyo akuchanekanga ngokwembono okanye ngaphakathi ngumvelisi. Ngaphandle kokulinganiswa okulandelekayo, nezixhobo zokulinganisa eziphambili azinakuqinisekisa iziphumo ezithembekileyo. Kubathengi, olu mahluko lwahlula ukuchaneka kokwenyani kwizimangalo ezingaqinisekiswanga.
Iimeko zendalo ezibhalwe kwingxelo yokuhlolwa zezinye izinto ezibalulekileyo ezidla ngokungahoywa ngexesha lokuthengwa. Ukulinganiswa kwegranite echanekileyo kuchaphazeleka kakhulu kubushushu obuqhelekileyo, ukufuma, kunye nokungcangcazela. Ingxelo esebenzayo idla ngokurekhoda ubushushu obungqongileyo, uzinzo lobushushu ngexesha lokulinganisa, kunye neemeko zokuxhasa ipleyiti yomphezulu. Ukuba ezi parameter azikho, ukuthamba okuxeliweyo kusenokungabonisi ukusebenza kwehlabathi lokwenyani xa iqonga lifakwe kwindawo yemizi-mveliso okanye yelebhu.
Ngaphaya kokuba tyaba, abathengi kufuneka baqwalasele iziphumo zovavanyo ezinxulumene nejometri. Ukuhambelana, isikwere, kunye nokuthe tye kubaluleke kakhulu kumaqonga egranite asetyenziswa ekuhlanganiseni izixhobo, oomatshini bokulinganisa abalungelelanisiweyo, okanye kwiinkqubo zokuhamba ezithe ngqo. Ezi mpawu zichaphazela indlela ipleyiti yomphezulu wegranite edibana ngayo neendlela zokuqondisa, iibheringi zomoya, okanye izigaba zokuchaneka. Iingxelo zokuhlola ezibandakanya ukuba tyaba kuphela kodwa ezingabandakanyi ezinye iiparameter zejometri zisenokunganeli kwizicelo eziphambili.
Isiqinisekiso sezinto ezibonakalayo sikwadlala indima ebalulekileyo ekuvavanyeni ukuthembeka kokuchaneka. Ingxelo efanelekileyo yezinto ezibonakalayo iqinisekisa uhlobo lwegranite esetyenzisiweyo, uxinano lwayo, kunye neempawu zayo zomzimba. Igranite emnyama enoxinano oluphezulu enesakhiwo esincinci ibonisa uzinzo olungcono lwexesha elide kunye nokuxinana kokungcangcazela. Ngaphandle kwamaxwebhu ezinto ezibonakalayo, abathengi abanakuqiniseka ukuba iqonga lenziwe ngegranite yokwenyani okanye ilitye eliphantsi elinokuphumelela ekuhlolweni kodwa liwohloke ngokukhawuleza ngokuhamba kwexesha.
Enye into ekufanele ukuba iqwalaselwe yindlela yokuhlola ngokwayo. Iindlela zokulinganisa eziphambili, ezifana ne-laser interferometry okanye i-electronic level mapping, zibonelela ngokuzithemba okuphezulu kuneendlela ezisisiseko zoomatshini zodwa. Iingxelo zokuhlola ezichaza igridi yokulinganisa, ubuninzi beesampulu, kunye nendlela yokucubungula idatha zibonelela ngokucace ngakumbi. Eli nqanaba leenkcukacha libonisa ukuba umenzi uyaqonda ukulinganisa ngokuchanekileyo njengenkqubo, kungekhona ukujonga kube kanye.
Kubathengi abafumana amaqonga okuchaneka kwegranite kwiindawo ezifuna kakhulu, iingxelo zokuhlolwa komntu wesithathu zinokuqinisa ngakumbi ukuzithemba. Ukuqinisekiswa okuzimeleyo ngamaziko e-metrology avunyiweyo okanye iilebhu ezivunyiweyo kubonelela ngongqinisiso olongezelelweyo, ngakumbi kwizicelo ezibalulekileyo. Nangona kungasoloko kuyimfuneko, ukuqinisekiswa komntu wesithathu kunciphisa umngcipheko wokuthenga kwaye kuxhasa amaqhinga okulawula umgangatho wexesha elide.
Kubalulekile nokuqaphela ukuba ukuthobela ukuchaneka akupheleli nje ekuhlolweni kokuhanjiswa. Umthengisi othembekileyo unika isikhokelo malunga namaxesha okulungisa kwakhona kunye neendlela zokuqinisekisa ixesha elide. Iipleyiti zomphezulu wegranite ezichanekileyo zizixhobo zokubhekisa, kwaye ukuchaneka kwazo kufuneka kuqinisekiswe rhoqo kulo lonke ixesha lenkonzo yazo. Amaxwebhu axhasa ukulinganiswa kwexesha elizayo anceda abathengi ukuba bagcine imigangatho yokulinganisa ehambelanayo endaweni yokuphatha ukuchaneka njengemfuneko yexesha elinye.
Ekugqibeleni, ukugweba ukuba iqonga lokuchaneka kwegranite liyahlangabezana neemfuno zokuchaneka kufuna umbono opheleleyo wedatha yokuhlolwa, ukulandeleka, iimeko zokulinganisa, kunye nomgangatho wezinto eziphathekayo. Izigqibo zokuthenga ezisekelwe kuphela kumanqanaba okunyamezelana okuqhelekileyo okanye uthelekiso lwamaxabiso zihlala zingazinaki ezi nkcukacha zibalulekileyo. Ngokuphonononga ngononophelo iingxelo zokuhlolwa nokuqonda oko zikumeleyo ngokwenene, abathengi banokuqinisekisa ukuba iqonga legranite abalikhethayo liya kusebenza njengesalathiso esithembekileyo nesizinzileyo kwizicelo zokuchaneka.
Kwimizi-mveliso apho izinto eziluncedo ze-microns kunye nokungaguquguquki kwexesha elide kuchazwa umgangatho, ukuqinisekiswa akulonyathelo lolawulo. Lusisiseko sokuthembana phakathi kwenjongo yoyilo, inyani yokuvelisa, kunye nokuthembeka kokulinganisa.
