Xa usiva 'i-advance precision machining', iingqondo ezininzi zitsibela ngqo kwi-micron-level tolerances kunye ne-CAD ekhanyayo. Leyo yinxalenye yayo, ngokuqinisekileyo, kodwa yinxalenye elula. Ibali lokwenyani liqala xa unebhetshi ye-Inconel 718 yokuphosa etafileni, ukuprintwa kubize i-± 0.02mm, kwaye ujongana ne-thermal drift, ukunxitywa kwesixhobo ukusuka ekubalekeni kokugqibela, kunye nokuba ugxininiso lokupholisa lukhona na. Lo msantsa phakathi kwenkcazo yethiyori kunye nenxalenye ebonakalayo-kulapho lo mdlalo udlalwa khona. Ayikokuba nomatshini onemigca emihlanu; imalunga nokwazi ukuba loo matshini uya kwenza ntoni nge-3 PM ngolwesiHlanu olufumileyo.
Isiseko: Iqala ngokuCasa
Awunakho ukuchaneka komatshini kwi-casting embi. Ndibone iiprojekthi ezininzi zichithwa ngenxa yokuba umntu wayecinga ukuba inqanaba le-CNC lingalungisa ngomlingo utshintsho oluphambili okanye i-subsurface porosity evela kwisiseko. I-machining yinkcazo yokugqibela, ebalulekileyo, kodwa ingqibelelo yenxalenye izalwe kwangaphambili. Yiyo loo nto ukudibanisa ukuphosa kunye nomatshini phantsi kophahla olunye, njengaseQingdao Qiangsenyuan Technology Co., Ltd. Xa iqela elifanayo elisebenza ngoomatshini likwajongene nokungunda kweqokobhe okanye inkqubo yotyalo-mali, ususa umaleko wonke wokukhombana ngeminwe kunye nokungaqiniseki.
Thatha umsebenzi wabo kunye ne-nickel-based alloys. Ukulungisa ezi ayingombandela nje wokukhetha ibakala elifanelekileyo lokufaka. Kuya kufuneka uqonde ukuhamba okuziinkozo kwinkqubo yokuphosa, ukuba imeko yokuphelisa uxinzelelo lwemathiriyeli iya kusebenzisana njani namandla akho okubamba, kwaye apho ezo ndawo zinenkani zinokuthi zizimele khona. Ukuba isakhelo asiveliswanga ngokulandelayo ukuchaneka kwangaphambili komatshini engqondweni, ulwa idabi elinyukayo ukusuka kunxibelelwano lwesixhobo sokuqala.
Ndikhumbula icandelo le-hydraulic manifold, intsimbi entsonkothileyo. Umzobo wawunobundlobongela. I-Foundry eyavelisa izithuba zokuqala ayizange idityaniswe nevenkile yomatshini. Isiphumo? Ubunzima bodonga obungahambelaniyo emva kobuso obubalulekileyo bokutywinwa, okukhokelela kubusuku obubi ngexesha lokugqiba. Ezinye iindawo zikhutshiwe, ezinye zavuza. Ngaba inkqubo yokuphosa iye yaphuculwa ngolungelelwaniso lokugqibela lomatshini njengegalelo elikhokelayo-into edityanisiweyo njengomthengisi QSY yenza njengesiqhelo-loo nkcitho kunye nokusebenza ngokutsha bekuya kuphetshwa kumthombo.
Umendo wesixhobo yiNgxoxo, Hayi Umyalelo
Isoftware yeCAM ikunika indlela yesixhobo. Umatshini uzama ukuwulandela. Umbono ongenangqondo kukuba esi sisiphelo sebali. Umbono onamava kukuba kulapho incoko iqala khona. Kuba yinyani ukuchaneka kwangaphambili komatshini, ngakumbi kwiijiyometri ezintsonkothileyo ezivela kufutshane ne-net-shape castings, indlela ecwangcisiweyo yidrafti nje yokuqala.
Kufuneka uphulaphule ukusika. Isandi, umbala we-chip kunye nefom, ukuhluka okuncinci ekufundweni kwemitha yomthwalo-zonke ziyimpendulo. Kumzimba wevalvu yentsimbi engatyiwa, sinokucwangcisa isantya somphezulu esingaguqukiyo kunye nokutya. Kodwa ukuba awuhlengahlengisi okwangoku isiphelo selitye sibandakanya umnqamlezo wangaphakathi ngokuchasene nodonga lwangaphandle olucocekileyo, uya kufumana incoko okanye ukuphambuka. Inxalenye 'yangaphambili' yile i-adaptive, phantse i-intuitive, umaleko wolawulo ohleli phezu kwekhowudi ye-G. Ngumatshini okanye umdwelisi wenkqubo esazi ukuba kule bhetshi ethile ye-17-4 PH engenasici ukusuka kwinyibilika ethile, kufuneka behlise ukondla nge-5% ezipokothweni.
Kulapho iminyaka engama-30 yemvelaphi ekhankanyiweyo ye-QSY iba yinto ebonakalayo. Asiyominyaka engama-30 nje yokuqhuba oomatshini; yiminyaka engama-30 yokwakha ilayibrari yengqondo malunga nendlela izinto ezivela kwi-alloys ezisekelwe kwi-cobalt ukuya kwi-iron yokuziphatha phantsi kwesixhobo. Ela thala leencwadi lazisa ezo zihlengahlengiso zincinci ezahlula indawo elungileyo kwegqibeleleyo.
I-Metrology: Ukulinganisa kukwazi (Mhlawumbi)
Nanku umgibe oqhelekileyo: ukuthembela kakhulu kwingxelo yeCMM. Ufumana iphepha lokuhlola inqaku lokuqala elinawo onke amaxabiso aluhlaza kwaye ucinga ukuba uyigolide. Kodwa yayiyintoni inxalenye yobushushu xa ilinganiswa? Ngaba iimpawu zedatha zicociwe kuzo zonke iintsalela zokupholisa kunye nee-micro-burrs? Ngaba i-clamping ngexesha lomlinganiso yayilinganisa ngokugqibeleleyo i-clamping ngexesha lomatshini? Ukuba akunjalo, loo ngxelo intle iyintsomi.
Kumsebenzi ochanekileyo, umlinganiselo ngumsebenzi wezandla ngokwawo. Sidla ngokusebenzisa indibaniselwano yeendlela. I-CMM yokunyamezela ijometri ngokubanzi, ewe. Kodwa kwiindawo zokutywinwa ezibalulekileyo, mhlawumbi iprofilometer yomphezulu. Kuba wazala iidayamitha kubunzulu, iimpawu ezincinci, igaji yomoya elungelelanisiweyo okanye isethi ethile ye-pin gage. Injongo kukulungelelaniswa-ukuqinisekisa ukuba onke amabali akho okulinganisa ayavumelana. Ndineemeko apho i-CMM yathi i-bore yayinyamezela, kodwa i-master plug gage ayiyi kufaneleka. Umoni? I-taper engaqondakaliyo okanye i-lobing ephoswe yi-CMM's point-cloud sampling. Ingqondo 'engaphambili' yenye yokuthandabuza okunempilo kwidatha yakho.
Kwinkampani ephethe yonke into ukusuka kwiziseko ezinkulu zentsimbi ukuya kwizinto ezicekethekileyo ze turbine yealloyi, le filosofi yemetrology kufuneka ihlaziywe kwaye iqonde izinto. Ukulinganisa isibiyeli sentsimbi esenziwa ngoomatshini akufani nokulinganisa i-cobalt alloy alloy-cast-cast cobalt alloy part enokugoba phantsi kobunzima bayo kwinqanaba le-CMM.
I-Arena ye-Alloys ekhethekileyo: Apho ithiyori idibana neSixhobo
Nabani na angajonga izantya ezicetyiswayo kunye nokutya kwe-Inconel kwincwadi yesandla. Ukulandela ukuvelisa inxalenye esebenzayo ngomnye umcimbi. Ukuchaneka kwangaphambili komatshini yeealloyi ezikhethekileyo ezifana ne-nickel-based okanye i-cobalt-based based luphononongo kwi-aggression elawulwayo. Udinga ukushisa okwaneleyo kwindawo yokucheba ukuze ugcine iplastiki yezinto eziphathekayo, kodwa kungekhona kakhulu ukuba usebenze-uqina umphezulu ube ngumaleko ongenakungeneka oya kutshabalalisa isixhobo sokudlula esilandelayo.
Ukukhetha isixhobo kuba kubaluleke kakhulu. Hayi nje nayiphi na i-ceramic okanye i-carbide eya kwenza. Ijometri yokufaka, isambatho, idizayini ye-chipbreaker-konke kufuneka kulungiswe. Isipholisi asenzelwa ukupholisa nje; yeyokuthambisa kunye nokukhutshwa kwetshiphu kuxinzelelo olunokugqithisa i-1000 psi. Ukungaphumeleli kulo naliphi na ikhonkco leli khonkco lithetha indawo echithiweyo, kwaye ezi mathiriyeli azibizi. Umda wemposiso ngunothi.
Oku kubuchule obuphambili kumthengisi onje QSY. Ukukhankanya kwabo ezi mathiriyeli asiyontetho; luphawu lokuba batyale imali kwisixhobo esithile somatshini wokuqina, iinkqubo zokupholisa uxinzelelo oluphezulu, kwaye okona kubalulekileyo, ulwazi lomsebenzisi ukuqhuba le gauntlet ngempumelelo. Ayiloshishini elisecaleni; sisakhono esizinikeleyo.
Uthungelwano: Impumelelo engabonakaliyo
Ekugqibeleni, makhe sithethe ngokuhamba. Olona tshaba lukhulu lokuchaneka kukungahambelani, kwaye ukungahambelani kudla ngokuvela kwizandla. Xa ukufakwa kwenziwa kumzi-mveliso omnye, kuthunyelwa kwenye ukuze kwenziwe umatshini orhabaxa, emva koko ukuya kwisithathu ukugqiba, wazisa okuguquguqukayo kwinqanaba ngalinye. Iimeko ezahlukeneyo zobushushu, iifilosofi ezahlukeneyo zokubopha, imigangatho eyahlukeneyo yezixhobo.
Umsebenzi odibeneyo ophethe iqokobhe lokungunda / utyalo-mali kunye ukuchaneka kwangaphambili komatshini ekuhambeni okudityanisiweyo kuphelisa ezi ziguquguqukayo. Inxalenye ayikhe iphole iye kwindawo engaziwayo phakathi kwemisebenzi emikhulu. Iqela elifanayo lobugcisa linokucwangcisa isango lokusa kunye neendawo zokunyuka ngokusekelwe apho iimpawu ezibalulekileyo zokugqibela ziya kwenziwa ngoomatshini, ukunciphisa isitokhwe esigqithisileyo kunye nokugqwetheka. Ivumela uyilo lwenkqubo epheleleyo ngokwenene.
Le yinzuzo efihlakeleyo emva kwemodeli egxile ngokuthe nkqo. Kuncinci malunga noomatshini bomntu kwaye ngaphezulu malunga nentambo engenamthungo yolawulo ukusuka kwintsimbi etyhidiweyo ukuya kugqitywa, icandelo elihloliwe. Ukuchaneka akwenziwa nje ngoomatshini; ifakwe kuyo yonke inkqubo ukusuka kusuku lokuqala. Xa ukhangela iindawo ezintsonkothileyo, ezinomgangatho ophezulu wokusebenza, ukuba ubunini benkqubo yokuphela ukuya esiphelweni ayiyonto yokunethezeka-ihlala ikuphela kwendlela yokuqinisekisa iziphumo ezifunwa ngushicilelo.
