Uma uzwa 'inkampani yokutshala imali enembayo', yini efika engqondweni? Mhlawumbe incwajana ehlanzekile enezingxenye ezicwebezelayo nezimangalo zokunemba kwezinga le-micron. Iqiniso, ukugaya kwansuku zonke, kubi kakhulu futhi kuthakazelisa kakhulu. Ukunemba kwangempela akukhona nje eshidini elicacisiwe; ishumekwe ensikeni enqwabelene yokusingatha amaphethini we-wax ngosuku oluswakeme, ekubizweni kokwahlulela ngobugqinsi begobolondo lensimbi enezindonga ezincanyana, kanye nokwethuka okuthule kokuhlolwa kwesihloko sokuqala. Izitolo eziningi kakhulu zithengisa iphupho 'lejiyometri eyinkimbinkimbi' kodwa zikhubeka ezintweni eziyisisekelo—idizayini yokungena engashintshi, ukuphathwa kwezimo ezishisayo ngesikhathi sokukhipha i-waxing, noma ukuvele bathole isiphetho esihle ngo-17-4 PH ngaphandle kokusebenzisa imishini eyeqisayo. Yilapho umugqa udwetshwa khona.
Isisekelo: Konke Kumayelana Nochungechunge Lwezinqubo
Awukwazi ukukhuluma ngokunemba ngaphandle kokuhlukanisa iketango, isixhumanisi ngesixhumanisi. Iqala ngesikhunta sephethini ye-wax. Uma lokho kucishiwe, yonke into elandelayo yizicucu ezibizayo. Ngike ngabona izitolo zithela imali ku-CNC ye-5-axis kanokusho ukuze kusetshenziswe i-wax kodwa zingawunaki umklamo womugqa wokupholisa, okuholela kuphethini ye-warpage ebonakala kuphela ngemva kokwakhiwa kwegobolondo le-ceramic. Igobolondo ngokwalo liwubuciko—i-dip ngayinye ne-stucco isicelo ayisona nje isinyathelo; kwakhiwa umgoqo oshisayo. Izendlalelo eziningi kakhulu, futhi usengozini yokuqhekeka kwegobolondo ngesikhathi sokushiswa kwezinga lokushisa eliphezulu; ambalwa kakhulu, futhi uthola ukuphumula, iphupho elibi lomuntu lapho insimbi encibilikisiwe ihlangana nesihlabathi. Ukukhethwa kwe-binder, i-zircon vs. ufulawa we-silica ohlanganisiwe wejazi lobuso... lokhu akukona okukhethiwe kwekhathalogi. Ziyizinqumo ezisekelwe ku-alloy ethelwayo. Ukuthulula ama-superalloys afana ne-Inconel 718? Udinga lelo jazi lokuqala ukuze libe ne-inert yamakhemikhali ukuze uvimbele ukusabela kwendawo. Inkampani ethola lokhu, njenge-QSY (Qingdao Qiangsenyuan Technology), ngeminyaka yayo engama-30, ungabheja ukuthi amashidi enqubo yawo anale mininingwane egxiliwe ngokuzama, yebo, iphutha.
Bese kuba khona ukuncibilika bese uthela. 'Ukunemba' lapha kuzwakala njengegama elingelona iqiniso. Kulawulwa izinxushunxushu. Ulinganisa izinga lokushisa lesithando somlilo, uketshezi lwensimbi, kanye nesidingo sokugcwalisa isikhunta ngokuphelele ngaphambi kokuba noma yisiphi isigaba siqine. Ezingxenyeni ezincane, ngezinye izikhathi udinga ukushisa igobolondo, umsebenzi obucayi othi uma weqile, uwenze buthaka. Sifunde lokhu kanzima ekuqhutshweni kwezindlu zezinzwa. I-geometry yayinalawa mashaneli amade, azacile. Ukuthulula okumbalwa kokuqala, igobolondo elibandayo, ukungahambi kahle. Sashisa ngaphambili, kodwa sashiseka ngokweqile, futhi amagobolondo aqhekeka ngesikhathi sokuphatha. Ukulungiswa bekungekho ebhukwini; bekuyi-preheat ehamba kancane, enesiteji kanye ne-tweak eya esangweni ukuze isebenze njengesinki esishisayo esingcono. Yilolo hlobo ukunemba kokutshala imali imininingwane oyithola ngokuphindaphinda kuphela.
Ukuqeda yilapho isithembiso sifezwa khona noma silahleka. Yilapho abaningi bethi khona 'i-net-shape' kodwa buthule ibhajethi yomshini osindayo. Ukusakaza okunembayo kweqiniso kunciphisa ukuvunyelwa kwesitoko. Kusho ukuthi amaphuzu akho anqunyiwe ahlelwe kusukela esigabeni sokuklama, amasango akho abekwe hhayi nje ukugeleza kodwa ukususwa kalula ngaphandle kokulimaza ingxenye. Kuhle inkampani yokutshala imali eqondile izoba nemishini yayo ye-CNC endlini, hhayi nje njengesengezo, kodwa njengesinyathelo sokugcina esididiyelwe. Kungani? Ngoba ithimba elifanayo eliphonsa ingxenye liyaqonda ukujula kwesikhumba, amandla engcindezi eyinsalela, kanye namaphoyinti edatha aqondile. Uma ngibheka ukusethwa kwe-QSY, iqiniso abalibalayo ukutshala imali kanye ne-CNC machining njenge-co-specializations akulona iqhinga lokuthengisa; kuwukuhamba komsebenzi okunengqondo. Uphonsa umzimba we-valve oyinkimbinkimbi ngensimbi engagqwali eyi-duplex, futhi umshini ubuso bokuvala endaweni efanayo, ngaphansi kwesambulela sekhwalithi efanayo. Iluphu yempendulo iqinile.
Izinto: Lapho I-Theory Ihlangana Ne-Crucible
Insimbi yekhabhoni, 316L, insimbi eyinsimbi—lezi isinkwa nebhotela. Kodwa ukuhlolwa kwangempela kwe-mettle ye-Foundry kuma-alloys angavamile. Ama-superalloy asekelwe ku-nickel kanye ne-cobalt ayisilwane esihlukile. Aziyona nje 'inzima emshinini'; yonke indlela yabo yokulingisa iyashintsha. Zinobubanzi obuqinile bokuqina obuncane, zijwayele ukudabuka, futhi zingasebenza ngomoya komoyampilo noma i-nitrogen uma ukuthela kungalawulwa. Ngikhumbula iphrojekthi ehilela ingxenye ye-cobalt-chrome yokufakelwa kwamazinyo. Imfuneko ye-bio-compatibility yayibaluleke kakhulu, okusho ukuthi akukho ukungcoliswa kwendawo. Isistimu yegobolondo evamile yayingasikwa; kwakudingeka sishintshele ejazini elikhethekile lobuso obusekelwe ku-alumina. Izinga lesivuno lalinonya enyangeni yokuqala. Yilapho isipiliyoni, noma ukuntuleka kwakho, kuvezwa khona ngesihluku. A inkampani yokutshala imali eqondile ebhala kalula 'ama-alloys akhethekile' kuwebhusayithi yayo kangcono ibe nezingodo zensimbi nezingxenye ezilahliwe ukufakazela ukuthi bawenzile umsebenzi wesikole.
Akukhona nje ukuwathela. Imayelana nokwelashwa kokushisa. Eziningi zalezi zingxubevange zithola izakhiwo zazo—amandla azo aqinile, ukumelana nokugqwala—kusukela emijikelezweni ethile yokushisa yangemva kokusakazwa. Uma isizinda sakho sisakaza futhi sihamba ngemikhumbi, sinikeza ibhomu lesikhathi esingaba khona. Ingxenye ingase idlule ekuhlolweni kokuqala kodwa yehluleke ekusebenzeni ngoba i-microstructure ayizange izinze. Ukuhlanganiswa kwe-Foundry ne-metallurgy akuxoxiswana ngakho ukuze kwenziwe umsebenzi oqondile. Udinga ukulawula indaba kusukela oketshezini kuya engxenyeni eqediwe.
Lokhu kungiletha ephuzwini elingokoqobo: ukulandeleka kwezinto ezibonakalayo. Kuzwakala kungokomthetho, kodwa kuyisisekelo sokwethembeka. Kunoma iyiphi ingxenye ebalulekile, udinga ukwazi inombolo yokushisa ye-master alloy, imibiko yekhemistri, nokuthi iliphi iqoqo legobolondo elithelwe kulo. Uma kuphakama inkinga ngemva kwezinyanga eziyisithupha, le datha ifanele isisindo sayo ngegolide. Iphendula umdlalo osolwayo ube yinkinga yobunjiniyela exazululekayo. Ukusebenza kochwepheshe kuzogxilisa lesi simiso, hhayi njengokucatshangelwa kwamuva kumakhasimende asemkhathini, kodwa njengendlela evamile.
I-Human Factor: Ama-Gauges, Amehlo, kanye Ne-Gut Feel
Alikho inani le-automation elingena esikhundleni seso elinokuhlangenwe nakho. Ngizokusho. Unjiniyela osebenza kahle angadlula endaweni yokubeka amagobolondo omisiwe futhi abone elilodwa elinenkinga ye-laminar ngenxa ye-sheen, noma ukuntuleka kwayo. 'Ukunemba' ku ukutshala imali kuvame ukukhiywa kulawa masheke wekhwalithi. Ukuhlolwa kwesihloko sokuqala kuwumkhuba. Awugcini nje ngokuqinisekisa ubukhulu nge-CMM; ubheka ukwakheka kokusanhlamvu ngaphansi kwesibonakhulu, uhlola i-micro-porosity ngokuhlola okungaphakathi, uhlola ukuphela kwendawo ngokuqhathanisa nesiqhanisi esibonakalayo. Ingabe kuzwakala kulungile? Lo mbono wakhelwe ekuboneni izinkulungwane zezingxenye, ezinhle nezimbi.
Ukuqeqesha leli hlo kuthatha isikhathi—iminyaka. Yingakho umlando weminyaka engu-30 wefemu efana ne-QSY ungewona nje umugqa wokumaketha; imele inkumbulo yesikhungo. Kusho ukuthi kukhona abantu abaphansi abakhumbula ngesikhathi i-geometry efanayo yehluleka ngo-2005 nokuthi bayilungisa kanjani. Lolo lwazi alubhalwa ngokuphelele ku-SOP; idluliswa ngesikhathi sokushintsha kwamashifu kanye nokuhlanganisana kokuxazulula izinkinga. Lesi sendlalelo somuntu siwukulawula kwekhwalithi ephezulu, ukubamba izinto isithwebuli esihleliwe esingase sizigeje.
Kodwa inkemba esika nhlangothi zombili. Ukuthembela 'olwazini lwezizwe' kungaba ubuthakathaka uma kungasekelwa idatha. Izitolo ezihamba phambili engisebenze nazo zihlanganisa lezi ezimbili. Umakadebona osebenzisa i-wax usola ukuthi umjovo we-wax usebenza kahle; bayayihlola ngokumelene nengcindezi yomlando/izingodo zokushisa zaleso sikhunta. Idatha iqinisekisa amathumbu, futhi ukulungiswa kwenziwa. Lokhu kubambisana yikho okwenza kube namandla, okuphindaphindekayo ukunemba kokutshala imali izinqubo, hhayi nje amaqoqo enhlanhla.
Lapho Ukunemba Kwehluleka: Ukufunda Ku-Scrap Bin
Noma ubani ongazange enze izicucu akenzi lutho. Okubalulekile ukuthi wenzani ngayo. Ekuqaleni kwesikhathi sami, sasine-oda eliphambili lochungechunge lwama-impeller asolwandle ngethusi. Umklamo wawuwubukhazikhazi—amavane azacile, agobile. Ukukhiqizwa kokuqala, izinga lokuhluleka elingu-70% kusuka kuma-mistruns kanye nokuvalwa okubandayo. Ukusabela ngokushesha kwaba ukusola izinga lokushisa lensimbi. Sayiphakamisa. Ukwehluleka okwengeziwe, manje nge-shrinkage porosity. Besijaha izimpawu.
Inkinga yangempela, eyavezwa ngemva kwesonto lokukhungatheka, yayikabili. Okokuqala, ukuhlanganiswa kwe-wax ('isihlahla') kwakuminyene kakhulu, okwenza igobolondo liphole ngokushesha phakathi nendawo ngesikhathi sokutubeka. Okwesibili, isango lalinganele ukuphakela lawo ma-vane azacile. Kwakudingeka sibuyele ekwakhiweni kwephethini ye-wax, sandise ubukhulu besango, futhi sibeke amaphethini ngokuhlukile esihlahleni. Kwasibiza isikhathi nemali, kodwa lokho kwehluleka kwangifundisa okuningi mayelana nesisindo esishisayo kanye nokudla kunanoma iyiphi incwadi. Ikhwalithi egxile inkampani yokutshala imali eqondile izoba nenqubo esemthethweni yokungalandeli ephoqelela lolu hlobo lokuhlaziya imbangela, hhayi nje ukulungisa ngokushesha ukuthumela i-oda.
Esinye isihibe esivamile ukwehluleka ukuxhumana nomklami. Onjiniyela abaklama ukwenza imishini ngokuvamile abaqondi ama-engeli asalungiswa, ukushwabana kwemvelo, noma isidingo sokujiya kwezindonga ezifanayo ukuze kufakwe uhlaka. Kungumsebenzi womsunguli ukubonisana, ukusho ukuthi, Singasakaza lokho, kodwa uma uvumela indawo eyi-0.5mm lapha esikhundleni sekhona elicijile, isivuno sakho nezindleko zizothuthuka kakhulu. Le mpendulo ye-design-for-manufacturability (DFM) iyisevisi ebalulekile. Akukhona ukuthi uthi cha; kumayelana nokusebenzisana ukwenza ingxenye idlaleke futhi inembe. Uma ubheka iphothifoliyo kumdlali oqavile, ungakwazi ukubona lokhu kuguquka ocwaningweni lwakhe—imiklamo iba lula ukulingisa ngokuhamba kwesikhathi, isibonakaliso sobambiswano lweqiniso, hhayi nje othatha ama-oda.
Imodeli Edidiyelwe: Ukusakaza Njengengxenye, Hhayi Ukuphela
Yilapho imboni iphokophele khona, noma lapho abadlali abaphumelele sebevele bekhona. Ukunemba kokutshala imali akuvamile ukuba kube yisinyathelo sokugcina. Ingxenye idinga imishini, mhlawumbe i-welding, ukwelashwa kokushisa, ukumbozwa kwendawo. Ukuba nalawa makhono ngaphansi kophahla olulodwa, noma kubambiswano oluphethwe ngokuqinile, kushintsha yonke into. Yehlisa izikhathi zokuhola, iqinisekisa ukuqhubeka kwekhwalithi, futhi yenza izinto zibe lula. Lapho amathimba okulingisa kanye nemishini esesakhiweni esisodwa, angahlala phansi nengxenye nomdwebo. Umakhi angakhomba lapho ukushintsha kancane kumongo wokulingisa kungabanikeza i-datum engcono. Unjiniyela we-Foundry angachaza ukuthi kungani indawo ethile inobukhulu obuphakeme kancane obufana nokusakazwa.
Lena imodeli eyenza umqondo wezingxenye eziyinkimbinkimbi, ezinenani eliphezulu. Ukubona emisebenzini enikeza imikhakha enzima njengamandla, i-aerospace, nezokwelapha. Akukhona nje ngokuba nomshini we-CNC; imayelana nokuhlanganiswa kwenqubo. Isibonelo, inkampani ehlinzeka ngesixazululo esigcwele sikakhiye wokujika kusukela ekulingiseni kuya engxenyeni eseyiqediwe yomshini, njengamasevisi ashiwo umnikelo ohlanganisiwe we-QSY, ingalawula lonke uchungechunge lwenani. Lokhu kuqeda ukukhombana ngomunwe okwenzeka lapho ukulingisa kwenqatshwa esitolo semishini esihlukile. Ukuziphendulela kucacile.
Ekugcineni, ilebula 'inkampani yokutshala imali eqondile' iyatholwa, ayifunwa. Itholwa ngokuvumelana kweqoqo elingu-100 elifanayo leqoqo 1. Itholwa ekhonweni lokuphatha hhayi nje imisebenzi eqondile kodwa ecishe ingenzeki, leyo edinga isayensi yezinto ezibonakalayo, ubunjiniyela bezinqubo, nekhono lezandla ukuze lihlangane. Kusemininingwaneni: amalogi okunakekela e-autoclave, izitikha zokulinganisa kuma-micrometer, ukubukeka okuhlelekile kodwa okusetshenziswa kahle kwelebhu yekhwalithi. Ukunemba kusesimisweni, futhi uhlelo lwakhiwe ngabantu ababone okwenzekayo uma lubhidlika. Leyo yindaba yangempela, kude nencwajana ecwebezelayo.
