Uma uzwa ukutshalwa kwezimali okungalungile, yini efika engqondweni? Kubantu abaningi, kuyinkulumo nje—isithembiso esingacacile sekhwalithi engcono noma izindleko eziphansi. Igama livela emibukisweni yezohwebo nasezindaweni zokuthengisa, ngokuvamile ngaphandle kwezinto eziningi. Eqinisweni, ukuthuthukisa le nqubo akukhona ngenhlamvu eyodwa yomlingo; kuwukugaya. Kumayelana nomphumela onqwabelene wokulungiswa okuncane okuyikhulu egumbini lamagobolondo, umnyango wephethini ye-wax, kanye nephansi lesisekelo. Abaningi bacabanga ukuthi konke kumayelana nokuthenga isithando somlilo esisha noma iphrinta esezingeni eliphezulu ye-3D yamaphethini. Lokho kuyingxenye yakho, impela, kodwa uma uhlelo lwakho lwegobolondo lungahambisani noma i-gating design yakho impofu, leyo mishini emisha iyisindo sephepha esibizayo. Ngike ngabona izitolo zithela imali ekuthuthukisweni okungakaze kugudluze inaliti ngamanani alahliwe.
Isisekelo: Ihlala Imayelana Negobolondo
Ake sithole okwangempela. Uma ufuna ukukhuluma ukutshala imali okuthuthukile, kuzomele uqale ngegobolondo. Yilapho izinkinga eziningi—namathuba—zihlala khona. Ngikhumbula ngisebenza ochungechungeni lwama-impellers ensimbi engagqwali kumkhiqizi wephampu. Ukucaciswa kudinga ama-vanes azacile ngendlela emangalisayo, aerodynamic. Izinga lethu le-scrap lalihamba cishe ku-40% ngenxa yokuqhekeka kwemithambo nokuqhekeka kwamagobolondo. Saxosha abasolwa abajwayelekile: i-slurry viscosity, ukuhlukaniswa kwesihlabathi se-stucco, umswakama wegumbi lokumisa. Ukuphumelela kwakungesona isixazululo sobuchwepheshe obuphezulu; ibigawula ngokucophelela izinga lokushisa elizungezile phakathi nomjikelezo wediphu ngamunye emasontweni amabili. Sithole ukwehla okungu-5-degree Celsius phakathi nesikhathi sasebusuku obekudala ukunamathelana kwamajazi okuyisisekelo okungahambisani. Ukuzinzisa lokho bekushibhile kunanoma iyiphi into entsha bese usika izinsalela ngesigamu. Ukuthuthukiswa lapha kuyimbudumbudu kabuhlungu.
Lokhu kuhlotshaniswa ngqo nobungcweti bomsebenzi osekunesikhathi eside ukhona. Thatha inkampani efana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ngaphezu kweminyaka engama-30 ekulingiseni nasekukhiqizeni imishini, kungenzeka ukuthi baphile ngokuphindaphinda inqwaba yama-tweaks weresiphi yegobolondo. Ubuchwepheshe babo kokubili isikhunta igobolondo kanye ukutshala imali kusho ukuthi bayiqonda ngokujulile isayensi yezinto—indlela izibophezelo ezihlukene ezisebenzisana ngayo nama-stuccos ahlukahlukene, indlela yokwakha igobolondo lomzimba we-valve yensimbi enkulu ngokumelene nengxenye yokuhlinza ye-cobalt alloy ethambile. Lolo hlobo lolwazi lwesikhungo luyisisekelo sentuthuko yangempela. Awukwazi ukuyithenga eshalofini.
Izinto zokwakha ngokwazo zilawula indlela yokuthuthukisa. Ukusebenza ngama-alloys asekelwe ku-nickel? Iphrofayili yokunweba okushisayo yegobolondo lakho namandla ashisayo kuba yinto engaxoxiswana nayo. Ukuthuthukiswa okuncane kokuqukethwe kukafulawa we-zircon wejazi lobuso kungaba umehluko phakathi kokusakazwa komsindo kanye nokugcwele izinyembezi ezishisayo. Akuwona umsebenzi owubukhazikhazi. Imayelana nochwepheshe abanolwazi lwamashumi eminyaka abazi, ngokubukeka nomuzwa wokudakwa, uma kulungile, kudala ngaphambi kokuba kubuye imiphumela yokuhlolwa kwelebhu.
I-Wax Room: Lapho Ukwethembeka Kwe-Dimensional Kunqotshiwe noma Kulahlekile
Wonke umuntu ugxile ensimbi, kodwa iphethini ye-wax i-DNA yokuphonsa. Noma yiliphi iphutha lapha liyakhula. Ukuthuthukiswa komjovo kuyimpi yokulwa nokucindezeleka kwangaphakathi. Sake saba nephrojekthi yabakaki be-aerospace lapho sasilokhu sithola i-warpage ecashile, engeyona into efanayo ngemva kokukhishwa kwe-waxing. Imodeli ye-CAD yayiphelele, ithuluzi lalikusha. Umlandu? Ingcindezi yomjovo we-wax nesikhathi sokubamba akuzange kulungiselelwe isilinganiso sendawo yejiyomethri yevolumu ukuya phezulu. Bekufanele sakhe umtapo wezincwadi omncane wamapharamitha womjovo womumo ohlukene wezingxenye zomndeni. Kwakuyisicefe, kodwa kwaqeda umthombo omkhulu wokukhukhuleka kobukhulu.
Yilapho ukuhlanganiswa nokusebenza kwemishini, njengama-QSY kuhlangene ukutshala imali kanye namakhono e-CNC, kukhombisa ukubaluleka kwawo kwamasu. Uma ukwazi ukukhiqiza iphethini ye-wax yomumo oseduze nenetha ngokusebenzisa ukunemba komshini wokufa okuyinhloko, uqala kusukela kusisekelo esiphezulu sokuthembeka. Ukuthuthukiswa kubhekwa ekuqaleni. Bese, noma yikuphi okulandelayo kwe-CNC machining engxenyeni yokugcina yensimbi kuncane, kugcina ubuqotho bempahla kanye nezindleko zokonga. Kungumbono ophelele wochungechunge lokukhiqiza.
Esinye isici esivame ukunganakwa ukuhlangana kwe-wax. Ikhono lezandla labashiseli abahlanganisa izihlahla ze-wax lithinta ngokuqondile isivuno. Isango eline-engeli engalungile noma i-weld joint ebuthakathaka izobangela ukuphela kwensimbi noma ukungahambi kahle. Ukuqeqeshwa nokujikijela okulula lapha kunikeza izinzuzo ezinkulu. Ngithole ukuthi ukurekhoda ngevidiyo indlela yesisebenzi esinekhono nokuyisebenzisela ukuqeqesha kuthuthukisa ukungaguquguquki ngaphezu kwanoma iyiphi isistimu ezenzakalelayo ebesingayithola ngaleso sikhathi.
I-Melt and Pour: Control Over Chaos
Nakhu lapho ithiyori ihlangana khona nomlilo. Ungaba negobolondo eliphelele kanye nephethini ye-wax ephelele, futhi ukuthulula okubi kucekela phansi yonke into. Kimi, ukwenza ngcono inqubo yokusakaza ngokwayo imayelana nokumiswa okunonya nokuqonda i-physics yokugcwalisa. Ngama-alloys aphezulu okushisa afana nalawo asekelwe ku-cobalt, ukulawula ukushisa okuphezulu kubalulekile. Amadigri ambalwa aphezulu kakhulu, futhi ukhulisa ukusabela kwegobolondo lensimbi; iphansi kakhulu, futhi uzibeka engcupheni yokungaziphathi kahle.
Senze uguquko olulula kodwa olusebenzayo lokuthulula ama-turbine blades: ukusuka ekuthululeni kokuwa kwamahhala kuye endaweni elawulwayo, etshekile ethela ngaphansi kwengubo encane ye-argon. Ukwehliswa kwe-turbulence kanye nokwakheka kwe-oxide kwabonakala ngokushesha kuma-radiographs. Ukuthuthukiswa kwakungekho emishinini (yize idivayisi yokuthulula enyakazayo yenziwa ngokwezifiso) kodwa kufilosofi-ibeka kuqala i-laminar igcwalise isivinini. Lolu uhlobo lwe-nuance yenqubo eqoqwa yi-multi-decade Foundry.
Ngemuva kokusakaza, inqubo yokukhipha ingenye indawo eyingozi. Ngibone ukulingisa okuhle kuqhekezwe ukudlidliza okuvusa umdlandla noma indiza yamanzi isethwe phezulu kakhulu. Ukuthuthukiswa bekusho ukuthuthukisa inqubo yokuhlobisa ethambile, eqondene nezinto ezithile, kwesinye isikhathi ngisho nokucwiliswa kwamakhemikhali amaphaseji angaphakathi ayinkimbinkimbi kakhulu. Ijika lokufunda elinensa, eliphindaphindayo.
CNC Machining: The Critical Finish Line
Lokhu kuyinkokhelo. Okwenziwe kahle ukutshala imali kufanele idinge imishini encane. Kodwa okuncane akusho lutho. I-interface phakathi kwe-Foundry nesitolo somshini yilapho iminwe ikhomba khona. Ukuthuthukiswa kwangempela kuvela ekuhleleni kwangaphambili. Isibonelo, ekusebenzeni okuhlanganisiwe okufana QSY, abahleli bezinhlelo ze-CNC kungenzeka baxhumane nonjiniyela be-Foundry ngesikhathi somklamo wokuqala wokungena. Bazovumelana ngamaphoyinti edatha, bengeze isitokwe somshini esincane ezindaweni ezibucayi, kanye nezakhiwo zedizayini ezikhomba izici zokulingisa, hhayi nje imodeli ye-CAD.
Lokhu ngikufunde kanzima. Sake saphonsa uchungechunge lwezinsimbi zensimbi engagqwali yezinga lasolwandle. Ukulingisa bekukuhle ngokwengxenye, kodwa isitolo sethu semishini sithwale kanzima ngoba isango lokuqala lishiye isigxobo esiphazamisa ukusethwa kwe-vise okujwayelekile. Umhlangano wamahora amabili phakathi kokulingisa nomshini wokuhola ngaphambi kokusetshenziswa kwamathuluzi ubuzolondoloza izinsuku zokuklanywa kabusha kwemidlalo kamuva. Intuthuko imayelana nokudilizwa kwezisele zomnyango.
Kuma-alloys aqinile, isu lomshini liyingxenye yokuthuthukiswa. Ukwazi ukuthi ingxubevange esekelwe ku-nickel inokuqina kancane, okuguquguqukayo kokuvela ekusebenzisaneni kwegobolondo kusho ukuthi uhlelo lwakho lwe-CNC kufanele lube nokusikwa kokuqala okuvamile. Lolu lwazi luvela ekubuyiseleni idatha yokwenza imishini (amanani okugqoka amathuluzi, imiphumela yokuqeda phezulu) eqenjini labasunguli, ukuvala iluphu.
Isilinganiso Sangempela: Ukuvumelana Nokwethembana
Ngakho-ke, i-impro iletha ini ngempela? Ngokuvamile akuwona umkhiqizo omusha oshintshashintshayo. Ikhono lokushaya ubukhulu be-CTQ (Critical-to-Quality) engxenyeni eyinkimbinkimbi, iqoqo ngemva kwenqwaba, yenkontileka ethatha iminyaka eyishumi. Ukuthenjwa iklayenti elifana nedivayisi yezokwelapha noma umkhiqizi wempahla yamandla elibeka kuwena. Abanandaba nengalo yakho entsha yerobhothi; bayakhathalela ukuthi ingxenye ngayinye ekuhlanganiseni kwabo iyalingana futhi iyasebenza.
Lesi yindawo lapho inkampani izakhela khona isithunzi sayo. Iminyaka engamashumi amathathu ebhizinisini, njenge-QSY, iphakamisa ukuthi bazulazule lezi ntuthuko ezikhulayo ngempumelelo kuwo wonke amashifu wezinto ezibonakalayo nemijikelezo yemakethe. Umsebenzi wabo ngama-alloys akhethekile ungitshela ukuthi baxazulule izinkinga ezinzima-ukulawula ukwakheka kokusanhlamvu ekubunjweni kwesigaba esikhulu, ukulawula ukucindezeleka okusalayo, ukuzuza ukushisela kwekhwalithi ye-X-ray ekufakweni okulungisiwe (uma kuvunyelwe yi-spec).
Ekugcineni, ukwenza ngcono ukutshalwa kwezimali kuwumqondo. Kuwukuzimisela ukumba u-40% wesilinganiso se-scrap ngoLwesihlanu ntambama futhi ungashiyi kuze kube yilapho une-hypothesis yokuhlola ngoMsombuluko. Yazisa umuzwa wengcweti njengokufunda kwe-spectrometer. Ukuthuthukiswa kuthulile, kwakhelwe esimisweni sansuku zonke, futhi kubonakala enqwabeni ekhulayo yama-oda athunyelwe ngempumelelo ezingxenye okungekho omunye umuntu ofuna ukuzithinta. Yilokho okuyisilinganiso sangempela.
