Xa usiva 'inkampani yotyalo-mali echanekileyo', yintoni ethi qatha engqondweni? Mhlawumbi incwadana ecocekileyo eneendawo ezikhanyayo kunye namabango okuchaneka kwenqanaba le-micron. Inyani, ukugaya imihla ngemihla, kubi kakhulu kwaye kunomdla ngakumbi. Ukuchaneka kokwenyani akukho kwiphepha elithile; lizinziswe kwigrit eqokelelweyo yokuphatha iipateni zewax ngemini efumileyo, kwikhwelo lomgwebo ngobungqingqwa beqokobhe lencakuba enodonga olucekethekileyo lweinjini yomoya, kunye noloyiko oluzolileyo lokuhlolwa kwenqaku lokuqala. Iivenkile ezininzi kakhulu zithengisa iphupha 'leejiometri ezintsonkothileyo' kodwa ziyakhubeka kwizinto ezisisiseko-uyilo olungagungqiyo lokungena, ulawulo lwe-thermal ngexesha lokuthotywa kwe-waxing, okanye ukufikelela nje ukugqiba okusemgangathweni kwe-17-4 PH ngaphandle kokubhenela kumatshini ogqithisileyo. Kulapho umgca utsalwa khona.
Isiseko: Konke malunga neNkqubo yeChayini
Awukwazi ukuthetha ngokuchanekileyo ngaphandle kokuqhawula ikhonkco, ikhonkco ngekhonkco. Iqala ngokungunda kwipateni yewax. Ukuba oko kucinyiwe, yonke into elandelayo yinkunkuma nje ebiza kakhulu. Ndikhe ndazibona iivenkile zigalela imali kwi-5-axis ye-CNC yezixhobo ze-wax kodwa zingaluhoyi uyilo lomgca wokupholisa, olukhokelela kwipatheni yephepha elibonisa kuphela emva kokuba iqokobhe leceramic lakhiwe. Iqokobhe ngokwalo liyi-art-dip nganye kunye ne-stucco application ayilonyathelo nje; sisithintelo sobushushu esakhiwayo. Iingqimba ezininzi kakhulu, kwaye ubeka umngcipheko wokuqhekeka kwegobolondo ngexesha lokutshiswa kobushushu obuphezulu; bambalwa kakhulu, kwaye ufumana ikhefu, iphupha elibi lobuqu apho isinyithi esinyibilikisiweyo sidibana nomgangatho wesanti. Ukhetho lwe-binder, i-zircon vs. Zizigqibo ezisekelwe kwi-alloy egalelwe. Ukugalela ii-superalloys njenge-Inconel 718? Udinga laa dyasi yokuqala ukuba ibe inert ngokwekhemikhali ukunqanda ukusabela komphezulu. Inkampani efumana oku, njengeQSY (Qingdao Qiangsenyuan Technology), ngeminyaka yabo engama-30, ungabheja amaphepha enkqubo yawo anezi nkcukacha zibethelelwe ngolingo kwaye, ewe, impazamo.
Emva koko kukho ukunyibilika kunye nokuthulula. 'Ukuchaneka' apha kuvakala ngathi kukho igama elingafanelekanga. Yisiphithiphithi esilawulwayo. Ulungelelanisa ubushushu beziko, ubumanzi besinyithi, kunye nesidingo sokuzalisa ukungunda ngokupheleleyo phambi kokuba naliphi na icandelo liqina. Kumacandelo amancinci, ngamanye amaxesha kufuneka ufudumeze igobolondo, umsebenzi obuthathaka othi xa ugqithisekile, uwenze buthathaka. Sifunde oku ngendlela enzima kwi-run ye-sensor housings. Ijometri yayinala mijelo mide, ibhityileyo. Ukugalela okumbalwa kokuqala, iqokobhe elibandayo, ukungahambi kakuhle. Safudumala kwangaphambili, kodwa saba nenzondelelo egqithisileyo, kwaye iigobolondo zaqhekeka ngexesha lokuphatha. Ulungiso lwalungekho kwimanyuwali; yayicotha, inqanaba lokutshisa kwangaphambili kunye ne-tweak kwisango lokungena ukuze lisebenze njenge-thermal sink engcono. Nantso ke uhlobo ukuphoswa kotyalo-mali oluchanekileyo iinkcukacha ozifumana kuphela kuphindaphindo.
Ukugqiba kulapho isithembiso sifezekiswa khona okanye silahlekile. Kulapho abaninzi babanga khona 'i-net-shape' kodwa ngokuzolileyo uhlahlo lwabiwo-mali lomatshini onzima. Ukuchaneka okuyinyani kunciphisa isibonelelo sesitokhwe. Kuthetha ukuba iindawo zakho ezisikiweyo zicwangcisiwe ukusuka kwinqanaba loyilo, amasango akho abekwe kungekuphela nje ukuhamba kodwa ukususwa ngokulula ngaphandle kokonakalisa inxalenye. Ulungile inkampani yotyalo-mali echanekileyo iya kuba nomatshini wayo we-CNC endlini, hayi nje njenge-add-on, kodwa njengenyathelo lokugqibela elidityanisiweyo. Ngoba? Ngenxa yokuba iqela elifanayo eliphosa inxalenye liyabuqonda ubunzulu bolusu, amandla okuxinzelela okushiyekileyo, kunye namanqaku e-datum achanekileyo. Xa ndijonga ukuseta QSY kaThixo, inyaniso badwelise utyalo mali kunye ne-CNC machining njenge-co-specializations ayiloqhinga lokuthengisa; luhambo olunengqiqo. Uphosa umzimba wevalve entsonkothileyo kwintsimbi ephindwe kabini, kwaye umatshini ubuso bokutywina kwindawo enye, phantsi kweambrela yomgangatho ofanayo. I-loop yempendulo iqinile.
Izixhobo: Apho ithiyori idibana neCrucible
I-Carbon steel, i-316L, isinyithi esityhidiweyo-ezi sisonka kunye nebhotela. Kodwa olona vavanyo lokwenyani lwe-mettle ye-Foundry lukwii-alloys ezingaqhelekanga. I-nickel-based kunye ne-cobalt-based superalloys yisilwanyana esahlukileyo. Azikho nje 'zinzima kumatshini'; yonke indlela yabo yokuphosa iyatshintsha. Zinoluhlu olumxinwa lokuqiniswa, luthanda ukukrazuka kushushu, kwaye lunokuphinda lusebenze ngeoksijini okanye initrogen ukuba ukugalelwa akulawulwa. Ndikhumbula iprojekthi ebandakanya icandelo le-cobalt-chrome yokufakelwa kwamazinyo. Imfuneko yokuhambelana nebhayoloji ibiyeyona nto iphambili, nto leyo ethetha ukungcoliseka komphezulu kungabikho nto. Inkqubo esemgangathweni yeqokobhe yayingayisiki; kwafuneka sitshintshele kwidyasi ekhethekileyo yobuso be-alumina. Umlinganiselo wesivuno wawukhohlakele kwinyanga yokuqala. Apha kulapho amava, okanye ukunqongophala kwawo, kubhencwa ngokukhohlakeleyo. A inkampani yotyalo-mali echanekileyo edwelisa ngokungaqhelekanga 'iingxubevange ezikhethekileyo' kwiwebhusayithi yayo ngcono ibe neelog zetsimbi kunye neendawo ezilahliweyo ukubonisa ukuba bawenzile umsebenzi wasekhaya.
Akunjalo nje ngokuwagalela. Imalunga nonyango lobushushu. Uninzi lwala ma-alloys afumana iipropathi zawo-amandla awo okuqina, ukumelana nokugqwala-ukusuka kwimijikelo yobushushu obuthile emva kokuphosa. Ukuba isiseko sakho siphosa kunye neenqanawa, banikezela ngebhombu yexesha elinokubakho. Inxalenye inokudlula kuhlolo lokuqala kodwa isilele kwinkonzo ngenxa yokuba i-microstructure ayizange izinziswe. Ukudityaniswa kwe-Foundry kunye ne-metallurgy ayinakuxoxwa ngomsebenzi ochanekileyo. Kufuneka ulawule ibali ukusuka kulwelo ukuya kwindawo egqityiweyo.
Oku kundizisa kwindawo ebonakalayo: ukulandeleka kwezinto eziphathekayo. Ivakala njenge-bureaucratic, kodwa sisiseko sokuthembeka. Kulo naliphi na icandelo elibalulekileyo, kufuneka wazi inani lobushushu le-master alloy, iingxelo zekhemistri, kwaye yeyiphi iqokobhe egalelwe kuyo. Xa kuvela ingxaki kwiinyanga ezintandathu kamva, le datha ixabisa ubunzima bayo kwigolide. Ijika umdlalo otyholayo ube yingxaki yobunjineli enokusonjululwa. Umsebenzi wobungcali uya kumiliselwa le nkqubo, kungekhona njengengcinga yasemva kubathengi be-aerospace, kodwa njengendlela eqhelekileyo.
I-Factor Human: I-Gauges, Amehlo, kunye ne-Gut Feel
Akukho xabiso lokuzenzekelayo elithatha indawo yeliso elidala. Ndizakuyithetha. Injineli eyinkqubo elungileyo inokuhamba ngaphaya kwendawo yokomisa amaqokobhe kwaye ibone enye enesiphako selaminar enokubakho yi-sheen, okanye ukungabikho kwayo. 'Ukuchaneka' kwi utyalo mali ihlala itshixiwe kolu vavanyo lomgangatho. Ukuhlolwa kwenqaku lokuqala lisiko. Awuqinisekisi nje imilinganiselo ngeCMM; ujonge ukwakheka kweenkozo phantsi kwemakroskopu, ujonga i-micro-porosity ngovavanyo lokungena, ukuvavanya umphezulu womphezulu ngokuchasene nesithelekisi somzimba. Ngaba ivakala ilungile? Le intuition yakhelwe ekuboneni amawaka eenxalenye, ezilungileyo nezimbi.
Ukuqeqesha eli liso kuthatha ixesha—iminyaka. Yiyo loo nto imbali ye-30 ye-firm efana ne-QSY ayingomgca wokuthengisa nje; imele inkumbulo yeziko. Kuthetha ukuba kukho abantu abaphantsi abakhumbulayo xa ijometri efanayo ingaphumelelanga ngo-2005 kunye nendlela abayilungisa ngayo. Olo lwazi alusoloko lubhalwe ngokugqibeleleyo kwiSOP; igqithiswa ngexesha lokutshintsha kweshifti kunye nokusombulula ingxaki. Lo umaleko womntu lolona lawulo lomgangatho ophezulu, ukubamba izinto ezinokuphoswa sisikena esicwangcisiweyo.
Kodwa likrele elintlangothi-mbini. Ukuthembela 'kulwazi lwezizwe' kunokuba bubuthathaka ukuba aluxhaswanga yidatha. Ezona venkile zingcono ndisebenze nazo zidibanisa ezi zimbini. Igqala lomsebenzisi likrokrela ukuba isitofu se-wax sisebenza ngokupholileyo; bayayijonga ngokuchasene noxinzelelo lwembali / amaqondo obushushu alo ngundo. Idatha iqinisekisa amathumbu, kwaye ukulungiswa kwenziwa. Le synergy yeyona nto idala ukomelela, ukuphinda-phinda ukuphoswa kotyalo-mali oluchanekileyo iinkqubo, hayi nje iibhetshi lucky.
Xa ukuchaneka kusilela: Ukufunda kwi-Scrap Bin
Nabani na ongenzanga imvuthuluka akenzanga nto. Into ephambili kukuba wenze ntoni ngayo. Ebutsheni bexesha lam, sasinocwangco kwiinqanawa ezininzi zobhedu. Idizayini yayingamabhongo—iziqwenga ezicekethekileyo nezigobileyo. Ukuqhuba kwemveliso yokuqala, i-70% yezinga lokungaphumeleli ukusuka kwii-mistruns kunye nokuvalwa okubandayo. Intsabelo ekhawulezileyo yaba kukutyhola ubushushu bentsimbi. Siyiphakamisile. Ukusilela ngakumbi, ngoku kunye ne-shrinkage porosity. Besileqa iimpawu.
Eyona ngxaki, eyatyhilwa emva kweveki yonxunguphalo, yayintlu-mbini. Okokuqala, i-wax assembly ('umthi') yayixinene kakhulu, ibangela ukuba iqokobhe liphole ngokukhawuleza embindini ngexesha lokudinwa. Okwesibini, isango lokungena lalinganelanga ukondla ezo zivane zibhityileyo. Kwafuneka sibuyele kuyilo lwepateni ye-wax, sandise ubungakanani besango, kunye nendawo yeepateni ngokwahlukileyo emthini. Kwasixabisa ixesha kunye nemali, kodwa oko kusilela kwandifundisa ngakumbi malunga nobunzima bobushushu kunye nokutya kunayo nayiphi na incwadi. Umgangatho ogxile inkampani yotyalo-mali echanekileyo iya kuba nenkqubo esemthethweni yokungahambelani enyanzelisa olu hlobo lohlalutyo lwengcambu, hayi nje ukulungisa ngokukhawuleza ukuthumela iodolo.
Omnye umgibe oqhelekileyo kukungaphumeleli konxibelelwano nomyili. Iinjineli eziyila umatshini kaninzi aziqondi ii-engile zokuyila, ukucutheka kwendalo, okanye imfuneko yobunzima bodonga obufanayo bokuphosa. Ngumsebenzi we-Foundry ukudibana, ukuthi, Singayiphosa loo nto, kodwa ukuba uvumela i-radius eyi-0.5mm apha endaweni yekona ebukhali, isivuno sakho kunye neendleko ziya kuphucula kakhulu. Le ngxelo yoyilo-yokwenziwa kwezinto (DFM) yinkonzo ebalulekileyo. Asikokuthi hayi; imalunga nentsebenziswano ukwenza indawo iphoseke kwaye ichaneke. Ukujonga iphothifoliyo evela kumdlali osekiweyo, unokusoloko ubona le nguqu kwizifundo zabo-uyilo luba luhle ngakumbi ngokuhamba kwexesha, umqondiso wobudlelwane bokwenene, kungekhona nje ukuthatha umyalelo.
Imodeli eDityanisiweyo: Ukuphosa njengeCandelo, hayi iSiphelo
Kulapho ishishini lisingise khona, okanye apho abadlali abaphumeleleyo sele bekho. Ukwenziwa kotyalo-mali oluchanekileyo kunqabile ukuba linyathelo lokugqibela. Inxalenye idinga i-machining, mhlawumbi i-welding, unyango lobushushu, i-surface coating. Ukuba nobu buchule phantsi kophahla olunye, okanye kwintsebenziswano elawulwa ngokuqinileyo, itshintsha yonke into. Inciphisa amaxesha okukhokela, iqinisekisa ukuqhubeka komgangatho, kwaye yenza lula ulungiselelo. Xa amaqela okuphosa kunye noomatshini akwisakhiwo esifanayo, anokuhlala phantsi kunye nenxalenye kunye nomzobo. Ingcali yoomatshini inokubonisa apho ukutshintshwa okuncinci kumbindi wokuphosa kuya kubanika i-datum engcono. Injineli ye-Foundry inokuchaza ukuba kutheni umphezulu othile unoburhabaxa obuphezulu kancinci.
Lo ngumzekelo onengqiqo kwizinto eziyinkimbinkimbi, zexabiso eliphezulu. Uyibona kwimisebenzi enceda amacandelo anzima njengamandla, i-aerospace, kunye nezonyango. Akukhona nje ngokuba nomatshini we-CNC; imalunga nenkqubo yokudibanisa. Umzekelo, inkampani ebonelela ngesisombululo esipheleleyo sokujika ukusuka ekujuleni ukuya kwindawo egqityiweyo yomatshini, njengeenkonzo ezichazwe ngumnikelo odityanisiweyo we-QSY, inokulawula lonke ikhonkco lexabiso. Oku kuphelisa ukukhombana ngeminwe okwenzekayo xa ukuphosa kukhatywa kwivenkile yomatshini eyahlukileyo. Ukuphendula kucacile.
Ekugqibeleni, ileyibhile 'inkampani yotyalo-mali echanekileyo' ifunyenwe, ayibangwa. Ifunyenwe ngokuhambelana kwebhetshi ye-100 ehambelana nebhetshi 1. Ifunyenwe kwisakhono sokuphatha kungekuphela nje imisebenzi ethe tye kodwa ekufutshane-engenakwenzeka, ezo zifuna isayensi yezinto eziphathekayo, ubunjineli benkqubo, kunye nobuchule bezandla ukudibanisa. Ikwiinkcukacha: iilogi zokugcinwa kwe-autoclave, izitikha zokulinganisa kwi-micrometers, ukubukeka okucwangcisiweyo kodwa kusetyenziswe kakuhle kwelebhu esemgangathweni. Ukuchaneka kukwinkqubo, kwaye inkqubo yakhiwe ngabantu abaye babona okwenzekayo xa idilika. Elo libali lokwenyani, kude nencwadana enemifanekiso emenyezelayo.
