Xa usiva 'inkampani yomatshini echanekileyo', yintoni ethi qatha engqondweni? Kubantu abaninzi, kwanabanye abafana abathengayo, ligama nje elimnandi levenkile enoomatshini abambalwa be-CNC. Yimpazamo yokuqala leyo. Akunjalo malunga noomatshini; imalunga ne-ikhosistim ebangqongileyo. Ngamashumi eminyaka yolwazi olucekethekileyo ekusekweni umsebenzi we-cobalt-based alloy versus a common stainless steel, ukuqonda okungathethwayo kwe-thermal dynamics ngexesha lokusikwa, kunye nezifundo ezikhohlakeleyo, ezibiza kakhulu ezifundwe kwi-stack-up yokunyamezela ekhangeleka igqibelele ephepheni. Ndibone iiRFQ ezininzi kakhulu eziyiphatha njengenkonzo yorhwebo. Abawuqondi umsantsa phakathi kwevenkile yomsebenzi kunye neqabane lokwenyani ngokuchanekileyo.
Isiseko ayisosisinyithi nje, yinkumbulo
Kulapho imbali ibalulekile, kwaye ndithetha imbali yokwenyani yokusebenza, hayi nje umgca kwiwebhusayithi. Thatha inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY). Ujonga irekhodi labo - ngaphezulu kweminyaka engama-30 besakha kunye nomatshini. Ayilonani nje elo. Leyo yinkumbulo yeziko. Kuthetha ukuba babone inguquko yenxalenye ukusuka kwintlabathi erhabaxa ukuya kutyalo-mali oluntsonkothileyo olukufutshane ne-net shape efuna ubuncinci kodwa obubaluleke kakhulu. Loo mvelaphi kwiinkqubo ezisisiseko ezifana nokungunda kweqokobhe kunye nokuphosa utyalo-mali ngokusisiseko kuyayitshintsha indlela yabo ngokuchanekileyo machining ulwahlulo lusondela kwibhiliti yezinto ezikrwada. Abayikusika isinyithi nje; bagqibezela ibali elaqala ngokungunda, ngemvakalelo yendalo yesakhiwo senkozo kunye namanqaku oxinzelelo olunokuthi uphoswe yindlu yomatshini esulungekileyo.
Idala uhlobo olwahlukileyo lokusebenza kakuhle. Xa iqela lakho lomatshini liqonda inkqubo yokuphosa ngokusondeleyo, unokuyila ukuphosa ukunciphisa ixesha lomatshini kunye neendleko kwasekuqaleni. Luphawu lwengxelo oluthatha iminyaka ukusekwa. Awukwazi ukuthenga oko ngomatshini omtsha we-5-axis. Ndikhumbula iprojekthi yendlu yempompo kwi-duplex steel stainless steel. Uyilo lokuqala lwaluneepokotho ezinzulu, ezinodonga olucekethekileyo ezaziyingxaki yokuphosa ngokucocekileyo nangakumbi kumatshini ngaphandle kokuphazamiseka. Ngenxa yokuba amaqela abo athethe - abafana abasisiseko kunye nabadwelisi benkqubo be-CNC - bacebise uhlengahlengiso oluncinci lwedrafti ye-angle kunye notshintsho lweradius kwinqanaba lokuphosa. Yongeza indleko engabalulekanga ekujuleni kodwa yanciphisa ixesha lomatshini malunga ne-30% kwaye yaphelisa ingozi enkulu ye-scrap. Nantso ixabiso elifihliweyo.
Kwaye uluhlu lwezixhobo lubalisa elinye ibali. Intsimbi, intsimbi, intsimbi, isonka nebhotolo eso. Kodwa xa ubona iialloys ezikhethekileyo ezifana ne-cobalt-based kunye ne-nickel-based alloys edwelisiweyo, uyazi ukuba ujongene nenqanaba elahlukileyo. Ukucutha ezi ayingombandela wokuthoba nje isantya sesondlo. Yifilosofi eyahluke ngokupheleleyo. Ukunxitywa kwesixhobo kuyaphawuleka, ulawulo lobushushu lubalulekile, kwaye iindleko zenxalenye eshiyiweyo ziyamangalisa. Inkampani esebenza ngokuvulelekileyo nezi ayikho nje a inkampani echanekileyo yomatshini; liqabane lokusombulula ingxaki kwizicelo ezigqithisileyo. Ufunda ukuwuhlonela loo mbandela, okanye uya kubhanga.
Apho Ukuchaneka Kuhlala Khona (AyiyoModeli yeCAD)
Wonke umntu ugxile ekunyamezeleni kokugqibela, i-±0.005mm callouts. Kodwa ukuchaneka kwangempela kwenzeka ixesha elide ngaphambi kokuba isixhobo sichukumise inxalenye. Ikwi-fixturing. Andikwazi ukugxininisa oku ngokwaneleyo. Ukwenziwa kotyalo-mali oluntsonkothileyo, olungalinganiyo, ukuyila isisimbiso esibeka ngaphandle komphezulu wedatum onokuthi ngokwawo unomahluko wokulahla bubugcisa. Kumalunga nokudala inkqubo ephindaphindwayo, eyomeleleyo yolungelelwaniso lwenxalenye engafanelanga ncam. Ndibone iinkqubo ezintle zisilela ngenxa yokuba ukulungiswa kuvumele ishumi lemilimitha ye-flex. Kwi-QSY, ngemvelaphi yabo yokuphosa, bahlala beyila kwaye bephosa izilungiso ngokwabo, elinqanaba lokudibanisa ngokuthe nkqo ongaliboni rhoqo. Ivakala ilula, kodwa yinzuzo enkulu.
Emva koko kukho i-metrology. Nayiphi na ivenkile inokuthenga iCMM. Kodwa ngaba bayayiqonda eyona nto ibaxelela yona? Ulawulo lwenkqubo yeStatistical (SPC) yomsebenzi wexesha elide kwii-alloys ezisekelwe kwi-nickel luqeqesho. Ayikokujonga nje inxalenye yokuqala neyokugqibela. Imalunga nokulandelela izixhobo zokunxiba, ukukhula kwe-thermal yomatshini, kunye nokwahluka kwezinto ezininzi. Awuneli nje ukulinganisa iindawo; ulinganisa uzinzo lwenkqubo yakho yonke. Yinyani inkampani echanekileyo yomatshini inale datha ebuyela umva kubasebenzi kunye nabadwelisi benkqubo kufutshane nexesha lokwenyani, ayingcwatywanga kwispreadsheet somphathi womgangatho. Yinkqubo ephilayo.
Kwaye isoftware? Sisixhobo, hayi intonga. Eyona software yeCAM ehlabathini iya kukunika indlela yesixhobo efanelekileyo ngokwethiyori. Kodwa umdwelisi wenkqubo onamava uyazi ukuba angayihoxisa nini. Bayazi ukuba ibakala elithile lensimbi ephosiweyo, i-angle yokungena engavumelekanga okanye i-stepover engekho-standard iya kuvelisa ukugqiba okungcono kunye nokwandisa ubomi besixhobo. Le yimvakalelo evela kwiminyaka yokusebenza kwemisebenzi, ukujonga imibala yetshiphu, ukumamela ukusikwa, kunye nokuhlola amawaka eenxalenye ezigqityiweyo. Unokufumana indlela yabo eneenkcukacha kwizifundo zemizekelo kwi-portal yabo https://www.tsingtaocnc.com. Ayikokuthengisa i-fluff; luluhlu lweengxaki ezisonjululweyo.
Ewe, Kodwa Incoko
Uphawu oluthembekileyo lwamava kukuvuma ukuthi ewe, kodwa okanye hayi, nantsi isizathu. Kwasekuqaleni kwekhondo lam lomsebenzi, ndandifumana imizobo enokunyamezelwa okuchazwe kwimigca yokwahlulahlula okanye yokufowuna ukuze kugqitywe isibuko kwisitishi sangaphakathi ebesingenakukwazi ukusisebenzisa. Ivenkile yomsebenzi elambileyo isenokuwucaphula nje kwaye uzame, okukhokelela kungquzulwano olungenakuthintelwa. Eyodwa inkampani echanekileyo yomatshini uzakufowunela. Baza kuchaza ukuba unyamezelo oluchaziweyo luqina kunolwahluko lwendalo olusuka kwinkqubo yokuphosa, ke kufuneka sixoxe ukuba zeziphi iimpawu zedatum ezibaluleke ngokwenene. Baza kucebisa umphezulu ogqityezelwe ngakumbi wokugqibezela okanye ucebise uyilo lokwenziwa kokwenziwa kwezinto (DFM) tweak.
Apha kulapho iifom zentsebenziswano. Ndikhumbula icandelo levalvu apho umxhasi wayefuna iRa 0.2μm igqibezele kwibhore yangaphakathi. Ingcinga yokuqala yayimnandi kwaye imnandi. Nangona kunjalo, ngokuqwalasela umsebenzi wecandelo kunye nemidiya ye-fluid, oomatshini bacebisa ukuba i-Ra 0.8μm igqitywe ngesixhobo esilawulwa ngokucokisekileyo se-single-point siya kusebenza ngokulinganayo, singaguquki ngakumbi, kwaye sinciphise iindleko ngesiqingatha. Babenedatha yokuyibuyisela - iimvavanyo zokunxiba, ukulinganisa ukuhamba. Oko kukongeza ixabiso, kungekhona nje ukusika isinyithi.
Icala le-flip kukwazi xa ungakwazi ukuthobela. Ubuso betywina obujikelezayo kwi-alloy-based alloy, i-flatness kunye ne-surface finish ayinakuxoxisana. Akukho ncoko yeDFM apho. Incoko itshintshela kwinkqubo yokuqinisekiswa, iprothokholi yokuhlola inqaku lokuqala, kwaye mhlawumbi novavanyo lwamangqina. Ukuzithemba ukuba neentlobo zombini zeencoko - enye yentsebenziswano kunye neyokungalalani - ibonisa umthengisi oqolileyo.
Iintsilelo yiKharityhulam yokwenyani
Akukho mntu kulo mmandla ulungile ngalo lonke ixesha. Izifundo ezincamathelayo zivela kwiimpazamo ezibizayo. Eyakudala ijongela phantsi isiqabu soxinzelelo olufunekayo emva komatshini orhabaxa wokusasa. Unomatshini wendlu enkulu yegiya ukucacisa, ijonga kwi-CMM, emva koko uyithumele ukunyanga ubushushu. Xa ibuya, ijijekile ngaphaya kokusindiswa ngenxa yokuba awushiyanga isitokhwe esaneleyo okanye awuzange ucinezele uxinzelelo-kwinqanaba lethutyana elifanelekileyo. Ndibe yinxalenye yaloo post-mortem. Yimvakalelo etyumzayo. Kodwa ikufundisa ukuba uhlale, usoloko uqwalasela imephu yoxinzelelo olushiyekileyo lwenxalenye ngaphambi kokucwangcisa.
Olunye ukusilela okuchuliweyo kukusukela uhlobo olungalunganga lokuchaneka. Ndakhe ndaxakwa kukubamba unyamezelo lwe-concentricity phakathi kwamabhore amabini kwi-manifold. Sachitha iiyure ekusetheni nasekuhloleni. Ngeli xesha, asiyihoyanga into yokuba umphezulu wokutywina othe tyaba, obonakala ulula, wawukhukuliseka ngenxa yokwahluka kobushushu obupholileyo ngexesha elide lomatshini. Inxalenye iphumelele ukujonga ubunzulu kodwa yavuza kuvavanyo. Ukuchaneka okwakubalulekile yayikukuba flat, kungekhona ukugxila. Iphinde yalinganisa imbono yam yonke ekufundeni umzobo: qonda umsebenzi kuqala, emva koko imilinganiselo.
Iinkampani ebezikho, njenge-QSY ngokuqhuba kwazo iminyaka elishumi elinesithathu, zinethala leencwadi lezi zifundo. Zizinziswe kwiinkqubo zazo zokusebenza eziqhelekileyo. Kungenxa yoko le nto yabo CNC Machining iinkonzo zecandelo lotyalo-mali zihlala zibandakanya uhlolo olusinyanzelo lwenkqubo kunye nesiqabu sethutyana soxinzelelo njengomgangatho wejometri ezithile, hayi njengezongezelelweyo. Babeke ixabiso kwiindleko zokusilela kwangaphambili ukuqinisekisa impumelelo yangoku.
Ke, Uthenga ntoni Ngokwenene?
Ekupheleni kosuku, xa uthetha a inkampani echanekileyo yomatshini, awuthengi ixesha lomatshini. Uthenga isigwebo. Uthenga ubulumko obuqokelelweyo bamawaka emisebenzi egqityiweyo, amanxeba aleyo ayihambanga kakuhle, kunye neenkqubo ezakhelwe ukuthintela ezo mpazamo ukuba zingaphindi. Uthenga iqela elijonga umzobo kwaye libone inkqubo, imigibe enokubakho, kunye nendlela eya kwindawo eyomeleleyo, ekumgangatho ophezulu.
Ngumahluko phakathi komthengisi kunye neqabane. Umthengisi unikezela ngenkonzo kushicilelo. Iqabane lizibandakanya nenjongo yoshicilelo. Bajonga icandelo lakho kwaye bacinge malunga nomjikelo wobomi bayo: indlela eya kuhlanganiswa ngayo, imikhosi eya kuthwala, indawo eya kuhlala kuyo. Ngesiseko ekubunjweni, inkampani efana ne-QSY ngokwemvelo icinga ngale ndlela - baye babandakanyeka ukususela ekuzalweni kwezinto njengento yokuthulula okutyhidiweyo.
Ngoko ke, kwixesha elizayo xa uvavanya a inkampani echanekileyo yomatshini, jonga ngaphaya koluhlu lomatshini. Buza ngezona ndlela zixhaphakileyo zokungaphumeleli kunye nento abayenzileyo ukuzithoba. Cela uphononongo lwe-DFM kwicandelo lentelekelelo. Impendulo yabo iya kukuxelela ngaphezu kwayo nayiphi na incwadana enemifanekiso eqaqambileyo. Ukuchaneka kokwenyani kukucinga, kwakudala ngaphambi kokuba ikhowudi yokuqala ye-G yenziwe.
