Uma onjiniyela abaningi bezwa 'i-precision prototype machining', ngokushesha bacabanga ngokubekezelela kwezinga le-micron kanye nokuqedwa kwangaphandle okungenasici. Lokho kuyingxenye yakho, impela, kodwa uma uke waba sesitezi sesitolo isikhathi eside ngokwanele, uyazi ukuthi inselele yangempela akukhona nje ukushaya inombolo ephrintiwe. Kumayelana nokwenza ingxenye esebenza ngempela emhlabeni wangempela, ngokuvamile ngezinto ezikulwela ngaso sonke isikhathi. Ngibone ama-prototypes amaningi amahle kakhulu, aphelele ahluleka ekuhlolweni ngenxa yokuthi inqubo igxile ohlotsheni olungalungile lokunemba. Ukunemba kweqiniso kusekucabangeni, hhayi nje ukusika.
I-Material Isithiyo Sokuqala
Ungaba nomshini ohamba phambili wama-axis angu-5 emhlabeni, kodwa uma ungaqondi ubuntu bezinto ezibonakalayo, ubhekene nezinkinga kusukela ekuqaleni. Yilapho isizinda sokulingisa, njengalokho esikwakhe khona amashumi eminyaka I-Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), iba yigugu. Asigcini nje ngokwenza amabhlogo omshini wesitoko; sivame ukuqala ngezethu abalingisi. Ngakho-ke uma iklayenti liletha idizayini yengxenye ye-aerospace enezinga lokushisa eliphezulu ku-Inconel 718, asigcini nje ngokucabanga ngokuphakelayo nesivinini. Sicabanga ngengcindezi eyinsalela evela ohlelweni lokutshala imali, ukuthi lokho kungase kusonte kanjani uma sikubamba, nokuthi singasishiya kuphi isitoko esengeziwe. Lolo lwazi lokuqala luwuhlobo lokunemba kwezitolo eziningi zemishini emsulwa eziphuthelwe.
Ngikhumbula i-prototype yengxenye ye-turbine seal. Ukuphrinta kubize ukucaba okuphambene okuqinile ku-flange elincanyana, elibanzi. Umzamo wokuqala, usebenzisa i-vise ejwayelekile kanye nokulandelana komshini wezincwadi zokufunda kusuka kubhulokhi ye-nickel-based alloy, kubangele ingxenye enhle, e-in-spec. Okusho ukuthi, kuze kube yilapho ikhululeka emshinini futhi isonteka njenge-chip yamazambane. Sizuze ukunemba komshini kodwa sehlulekile ukunemba kwe-prototype. Ingxenye yayingenamsebenzi.
Ukulungiswa kwakungewona umshini wokuthakazelisa. Bekubuyela emthonjeni. Sihlanganyele nethimba lethu labadidiyeli be-shell mold ukuze sidizayine ukulingisa okwenziwe ngomshini ngezimbambo eziyisisekelo zosekelo ezindaweni ezingabalulekile. Lezi zimbambo zazinza ingxenye ngesikhathi somshini futhi zacinywa i-EDM'd njengesinyathelo sokugcina. Ingxenye yokugcina yayibambe isimo sayo. Lokho kuhlanganisiwe ukunemba kwe-prototype machining-kucatshangelwa lonke uhambo ukusuka ensimbi encibilikisiwe kuya engxenyeni eseqediwe.
Lapho Sekwanele Isitha
Ama-prototypes awokufunda, ngakho-ke kunesilingo sokusika amakhona. Basho nje imodeli yokulinganisa isheke. Kodwa ngokubona kwami, yonke i-prototype kufanele yenziwe ngomshini ngenhloso yokuthi ibe yingxenye yokukhiqiza. Kungani? Ngoba ukwehluleka okuthola esigabeni se-prototype kungamaphuzu edatha abaluleke kakhulu ozowathola. I-prototype ebudlabha ingase ilingane, ifihle iphutha ledizayini eliba yisikhumbuzo sesigidi samadola kamuva.
Sake saba neklayenti lensiza yezokwelapha—ithuluzi lokuhlinza. I-prototype yokuqala yezindlu eziyinhloko yenziwa ngomshini isuka ku-316 engenasici. Ihlanganiswe kahle, futhi umshini wasebenza. Kodwa ngesikhathi sokuhlolwa kokusebenza, i-anodized aluminium actuating lever yaqala ukudlala kancane ngemva kwemijikelezo engamakhulu ambalwa. Inkinga kwakungekona umshini wesivikelo; kwakuwubulukhuni kanye nezici zokugqoka ze-prototype material ngokumelene nempahla yokukhiqiza ehleliwe. Besisebenzisa isitokwe esitholakala kalula emshinini ngesivinini. I-prototype enhle eyanele icishe yaqinisekisa ukubhanqa kokubalulekile okunephutha.
Siphikelele ekwenzeni i-iteration elandelayo kusukela kungxubevange ye-cobalt-chrome yangempela ecaciswe ukukhiqizwa. Kwakuyisihogo kumathuluzi, kubiza ngokuphindwe kathathu, futhi kuthatha isikhathi eside. Kepha kwembule inkinga ebabazekayo phakathi kwezingxenye ezimbili ezingaphansi komthwalo, okuphoqa ukuthi kuguqulwe ukwakheka kusixhumi esibonakalayo. Lokho ukunemba ekuthathweni kwezinqumo: ukwazi ukuthi ukwethembeka kwe-prototype kufanele kudlulele nini ekuqinisekiseni izinto ezibonakalayo, hhayi nje i-geometry.
Amathuluzi Eshedini: Ngaphezulu nje kwe-CNC
Wonke umuntu ukhuluma nge-CNC machining yama-prototypes, futhi iyi-workhorse. Kodwa ikhono langempela livela ekubeni nezinqubo ezifanele zesibili nezokusekela ngaphansi kophahla olulodwa. Ngo QSY, ngenxa yokuthi siphuma kusizinda se-foundry, asiboni ukwenza imishini njengesevisi ehlukile. Ithuluzi elilodwa ebhokisini.
Isibonelo, i-impeller prototype eyinkimbinkimbi ingaba ngcono njenge-hybrid. Singase sikhiqize i-core geometry njengendlela yokutshala imali ku-duplex stainless steel, sithole amavesi angaphakathi angenakwenzeka noma abize kakhulu umshini. Bese siyiletha emnyangweni we-CNC ukuze kwenziwe ngokunembayo ubuso obukhuphukayo, ibhore, namathiphu ensimbi. Le ndlela exubile ithola i-prototype esebenzayo, emele iklayenti ezandleni zeklayenti ngokushesha futhi ngokuvamile ngezindleko eziphansi kunokuzama ukukhipha i-billet eqinile. Ukunemba kusekukhetheni iketango lenqubo elilungile.
Yilapho ubona khona umehluko phakathi kwesitolo semisebenzi kanye nomnikezeli wezixazululo. Isitolo somsebenzi sicaphuna umbhalo. Sibheka okubhaliwe bese siyabuza, Kwenzelweni lokhu? Yini okudingeka imelane nayo? Khona-ke singase siphakamise ukuthi, Umzimba oyinhloko ungaba ukunemba kwesikhunta segobolondo ukuze konge isikhathi nezinto ezibonakalayo, futhi sizoqedela ukuxhumana okubalulekile ku-CNC. Lokho kuxoxisana, okuzalwe kusukela eminyakeni engu-30 yokwenza kokubili izingxenye zabalingisi neziwumshini, kuwungqimba olubalulekile lwesevisi.
I-Communication Loop Iwukubekezelelana Okubalulekile
Nansi imfihlo encane engcolile: umthombo omkhulu wephutha ku ukunemba kwe-prototype machining akukhona ukunemba kwethuluzi lomshini; ukuxhumana. Umdwebo uyimodeli yenhloso. Izikhala ekuqondeni zigcwaliswa ngokuqagela, futhi kulapho ama-prototypes ahamba kahle khona.
Manje sigcizelela ucingo lokuqala kunoma iyiphi i-prototype eyinkimbinkimbi, ngisho noma ibambezela i-PO ngosuku. Sibuza ukuthi kungani mayelana nezici ezithile. Ingabe leyo ndawo ingeyobuhle kuphela, noma eyokugeleza kwengcindezi? Ingabe le ndawo iwubuso obuvaliwe noma isembozo nje? Impendulo ishintsha indlela esibhekana ngayo—isu lendlela yamathuluzi, ukukhetha komsiki, ngisho nohlelo lokusebenza.
Lokhu ngakufunda kabuhlungu kusenesikhathi. Iklayenti lithumele imodeli yendlu yezinzwa enembobo eyimpumputhe ejulile, enobubanzi obuncane. Siyifake kahle ukuze sicacise. Babethukuthele. Kungani? Ngoba behlulekile ukuxhumana ukuthi imbobo bekungeyomugqa we-fiber optic onamathiselwe, futhi isiphetho esingaphezulu kusuka ekusebenzeni kwethu kokumba besingaqinile ngokwanele ukuze okunamathelayo kuhlangane kahle. Kwadingeka sibuyele emuva futhi siwubhoboze mathupha umgodi. Ingxoxo yemizuzu emihlanu ibingayigcina isonto. Manje, leyo ngxoxo iyingxenye evamile yenqubo yethu. Ukunemba kwengxenye yokugcina kuhambisana ngokuqondile nokunemba kwengxoxo yokuqala.
Ukubheka Phambili: Ukunemba Njengefilosofi
Pho lokhu kusishiya kuphi? Ngemva kweminyaka engamashumi amathathu ekulingiseni nasekukhiqizeni imishini, ngiyabona ukunemba kwe-prototype machining iyavela. Kuncane mayelana nokujaha okweshumi kwe-micron embikweni we-CMM nokunye mayelana nokwethembeka okuphelele. Ingabe i-prototype iziphatha ngendlela ezokwenza ingxenye yokukhiqiza? Yilowo mbuzo.
Kusho ukuthi kwesinye isikhathi ukukhetha ukubekezelelana okuxega kancane ukuze kulondolozwe impahla, noma ukuchitha isikhathi esengeziwe esicini esingabalulekile ngoba kwazisa isinqumo senqubo yokukhiqiza. Imayelana nokusebenzisa amandla e-spectrum egcwele, njengalokhu esakhe kukho QSY, lapho ulwazi oluvela esithandweni lwazisa i-vise yomshini, futhi impendulo evela esikhungweni somshini yazisa umklamo wokubunjwa kwesikhunta.
Umgomo wokugcina awulokothi ube yingxenye ecwebezelayo ebhokisini. Kuwucezu lwedatha oluqinisekisiwe. I-prototype ephumelelayo, eyenziwe ngomshini ngale ncazelo ebanzi yokunemba, ayibonisi nje ukuthi umklamo uyasebenza. Isusa engozini yonke indlela eya ekukhiqizeni. Ikutshela ukuthi izindleko zangempela zizoba kuphi, ukuthi izinselelo zezinto ezibonakalayo zikuphi, nokuthi umklamo udinga ukugoba ukuze uhlangabezane neqiniso lokukhiqiza. Lelo inani langempela. Futhi ukufeza lokho kudinga okungaphezu nje kwesitolo semishini esihle; idinga uzakwethu ocabanga ngawo wonke umjikelezo wempilo wengxenye, kusukela kokusetshenziswa okuluhlaza kuya ekusetshenzisweni ekugcineni. Lolo uhlobo lokunemba olubalulekile.
