Kwicandelo lokwenziwa kweenqwelo-moya, umda wempazamo awukho. Ukususela kwiibhloko ze-turbine ze-jet injini ukuya kwi-fuselage yesakhiwo sesathelayithi, yonke into kufuneka ihlangabezane nemigangatho elinganiswe kwii-microns ezinenombolo enye. Kule meko inzima, ukuchaneka kwenkqubo yokwenziwa kulungile kuphela xa kuthelekiswa nokuzinza kwezixhobo ezisetyenziselwa ukwakha nokulinganisa ezi ndawo. Nangona isoftware ephucukileyo kunye nesikhokelo se-laser zihlala zitsala ingqalelo, isiseko sobunjineli bokuchaneka sixhomekeke kakhulu kwizinto eziye zahlala ixesha elide: i-granite echanekileyo kakhulu.
Izinto zegranite azisezona nje iipleyiti zomphezulu ezilula zokuhlolwa ngesandla; ziye zaguquka zaba zizinto ezintsonkothileyo, zesakhiwo eziyinxalenye yeeCoordinate Measuring Machines (CMMs), amaziko oomatshini akhawulezayo, kunye neenkqubo zokulungelelanisa i-optical. Eli nqaku lihlola isizathu sokuba igranite echanekileyo ihlala iyinto ekhethwayo kushishino lweenqwelo-moya kunye nendlela eqinisekisa ngayo ukhuseleko kunye nokusebenza kwesizukulwana esilandelayo sokubhabha.
Ukubaluleka kozinzo lwemilinganiselo
Izinto zeenqwelo-moya zihlala zinkulu, zintsonkothile, kwaye zenziwe ngezinto ezilukhuni ukwenza umatshini ezifana ne-titanium kunye ne-Inconel. Ngexesha lenkqubo yokuvelisa, ezi ndawo ziphantsi kwamandla amakhulu kunye notshintsho lobushushu. Ukuqinisekisa ukuba inxalenye ifanelekile ukuba nomoya, kufuneka ilinganiswe neplane yesalathiso ezinzileyo kunenxalenye ngokwayo. Le yingcamango "yeplane yesalathiso". Ukuba iqonga lokulinganisa liyakhula, lincipha, okanye lingcangcazela kancinci, idatha eqokelelweyo iyachaphazeleka, nto leyo enokubangela ukufakwa kweendawo ezineziphene.
I-granite echanekileyo kakhulu, ngakumbi iiklasi ezifana ne-granite emnyama enobunzima obumalunga ne-3100 kg/m³, inika isisombululo esigqibeleleyo sozinzo olunemilinganiselo. Ngokungafaniyo nentsimbi okanye isinyithi esityhidiweyo, esinokugoba phantsi koxinzelelo okanye utshintsho lobushushu, i-granite isebenza njengesiseko esingathathi cala, esingenamsebenzi. Ibonelela "ngenqaku le-zero" elingatshintshiyo, iqinisekisa ukuba imilinganiselo ethathwe ngabalandeleli be-laser okanye ii-CMM zizibonakaliso ezichanekileyo zenyani. Kwishishini apho ukuphambuka okuncinci kunokukhokelela ekuphelelweni kokudinwa okukhulu, olu zinzo aluyonto nje yokunethezeka—luyimfuneko yokhuseleko.
Uzinzo lobushushu: Umgcini othuleyo woBuchule
Enye yezona ngxaki zibalulekileyo kwimveliso yeenqwelo moya kukulawula ubushushu. Iiholo ezinkulu zokwenza izinto zinokuba nokuguquguquka kobushushu imini yonke, kwaye inkqubo yokwenziwa kwezinto ngokwayo ivelisa ubushushu obukhulu. Iintsimbi zine-coefficient ephezulu yokwandiswa kobushushu (CTE), oko kuthetha ukuba ziyakhula xa zishushu kwaye zinciphe xa zipholile. Ukuba ibhulorho yeCMM okanye isiseko somatshini senziwe ngentsimbi, siya kwanda njengoko umzi-mveliso ufudumala, nto leyo ebangela ukuba umatshini ulahlekelwe kukulinganiswa kwawo kwaye ungenise iimpazamo zokulinganisa.
I-Granite ine-CTE ephantsi kakhulu, ephantsi kakhulu kuneyentsimbi. Le propati yendalo yenza ukuba ikhuseleke ngokupheleleyo kutshintsho oluncinci lobushushu olufumaneka kwiindawo ezilawulwayo. Ngokusebenzisa i-granite kwiindawo zokwakha iinkqubo zokuhlola kunye nokuvelisa, iinjineli zeenqwelo-moya ziqinisekisa ukuba i-geometry yomatshini ihlala ihleli nokuba imeko yemozulu injani na. Olu zinzo lobushushu olungasebenziyo lususa isidingo seenkqubo zokupholisa ezisebenzayo ezintsonkothileyo nezibizayo kwizicelo ezininzi, zibonelela ngesiseko esithembekileyo somsebenzi ochanekileyo.

Xa isixhobo sokusika sidibana nezinto eziqinileyo ezifana ne-titanium landing gear component, sivelisa ukungcangcazela okuphezulu. Ukuba isakhiwo somatshini siyafunxa kwaye sibonakalise oku kungcangcazela, ukugqitywa komphezulu kuyaphela, kwaye ubomi besixhobo buyancipha kakhulu.
Ulwakhiwo lwe-granite oluyikristale lunika iipropati zokudambisa ezigqwesileyo—zingcono ngokuphindwe kalishumi kunentsimbi. Oku kuthetha ukuba izinto zegranite zifunxa amandla okungcangcazela endaweni yokuwathumela. Kwimeko yomatshini we-CNC okanye iskena se-laser esinesantya esiphezulu, isiseko segranite sisebenza njengesifunxi esikhulu sokutshoka. Olu buchule bokudambisa buvumela amazinga aphezulu okutya kunye nezenzo zokusika ezithambileyo, okubangela ukugqitywa okuphezulu komphezulu kunye nokuncipha kokuguguleka kwizixhobo zokusika ezibizayo. Kwiinkqubo zokuhlola ukukhanya, olu zinzo lubaluleke ngokulinganayo; nokuba kukungcangcazela okuncinci okuvela kwinkqubo ye-forklift okanye ye-HVAC ekufutshane kunokufiphaza iiskeni zesisombululo esiphezulu, okwenza idatha ingabi namsebenzi.
Ukuqina kunye nomthamo wokuthwala umthwalo
Izinto ze-aerospace zihlala zinzima, kwaye izixhobo ezisetyenziselwa ukuzibamba nazo zinkulu ngokulinganayo. Iqonga le-granite elichanekileyo kufuneka lixhase le mithwalo ngaphandle kokuguqa. I-granite emnyama enobunzima obuphezulu ine-modulus ephezulu yokuthamba, nto leyo ethetha ukuqina okungaqhelekanga. Oku kuqina kuqinisekisa ukuba iqonga lihlala lithe tyaba nokuba liphantsi kwemithwalo enzima.
Ngaphezu koko, igranite ayinamagnethi kwaye ayibolisi. Kwimveliso yeenqwelo-moya, apho kusetyenziswa khona izixhobo ze-elektroniki kunye nee-sensors zemagnethi ezibuthathaka, uhlobo lwegranite olungenamagnethi luthintela ukuphazamiseka. Ukongeza, ngokungafaniyo nentsimbi ephosiweyo, igranite ayibolisi. Ayinakumelana nezinto ezipholileyo, iioyile, kunye nezinyibilikisi ezifumaneka rhoqo kumgangatho wevenkile, ukuqinisekisa ukuba umphezulu ochanekileyo uhlala ungaguquki kangangeminyaka emininzi ngaphandle kokugcinwa kakhulu. Olu bude bexesha elide lwenza ukuba ibe lutyalo-mali olungabizi kakhulu kwiinkqubo zeenqwelo-moya zexesha elide ezinokuthatha iminyaka engamashumi amabini nangaphezulu.
Ukwenziwa Kwemveliso Okuphambili kunye Nokwenziwa Ngokwezifiso
Imfuno yegranite kwi-aerospace iqhubele phambili kakhulu kwindlela ezi zinto zenziwa ngayo. Akwanelanga ukunqumla nje ibhloko yelitye; usetyenziso lwe-aerospace lwanamhlanje lufuna iijometri ezintsonkothileyo, izinto ezifakwe ngaphakathi, kunye nokuqina kwinqanaba le-nanometer.
Izakhiwo zanamhlanje ngoku zisebenzisa oomatshini bokugaya abakhulu abazenzekelayo abalandelwa kukutsalwa ngesandla ziingcali ukuze kufezekiswe ukunyamezelana kokuthamba okwakucingelwa ukuba akunakwenzeka ngaphambili. Ezi nkqubo ziqinisekisa ukuba izinto zegranite ziyahlangabezana nemigangatho yamazwe ngamazwe efana ne-DIN 876 okanye i-ASME B89.3.7. Ukongeza, eli shishini libona umkhwa wokufikelela kwiinkcukacha ezinkulu. Njengoko izakhiwo zeenqwelo-moya zikhula—njengeendawo zamaphiko eenqwelo-moya zothutho zesizukulwana esilandelayo—iitafile zokuhlolwa kwegranite ziyanda, ubude obuthile ngoku budlula iimitha ezili-9.
Kukwakho nomkhwa okhulayo wokusetyenziswa kwe-"granite yokwenziwa" okanye iimineral castings kwizixhobo ezithile zoomatshini. Ezi zinto zidibanisa i-granite etyumkileyo kunye nee-epoxy resins ukwenza izakhiwo ezikhaphukhaphu kwaye zinokuphoswa kwiimo ezinzima ngelixa zigcina iingenelo zobushushu kunye nokufuma kwelitye lendalo. Nangona kunjalo, kwinqanaba eliphezulu le-metrology kunye nokuzinza kwexesha elide, i-granite emnyama yendalo ihlala isemgangathweni wegolide ngenxa yobudala bayo bejoloji kunye nendalo yayo engenaxinzelelo.
Indima yoQinisekiso kunye nokuLandelelwa
Kwicandelo leenqwelo-moya, uxwebhu lubaluleke njengenxalenye ebonakalayo. Yonke inxalenye yegranite esetyenziswa kwisiqinisekiso seendawo ezibalulekileyo zokubhabha kufuneka nayo iqinisekiswe. Oku kubandakanya uvavanyo oluqatha kwiilabhoratri ezilawulwa yimozulu ukuqinisekisa ukuba zithe tyaba, ziyafana, kwaye zixinene.
Abavelisi kufuneka banike izatifikethi zokulinganisa ezinokulandelelwa ngokwemigangatho yesizwe neyehlabathi (njenge-NIST okanye i-PTB). Olu luhlu lokugcinwa luqinisekisa ukuba "umlawuli" osetyenziselwa ukulinganisa inxalenye yenqwelo moya uchanekile. Ngaphandle kolu landelelwano, idatha eveliswe yi-CMM okanye i-laser tracker ayisebenzi.
