Xa kufikwa kushicilelo lwe-3D kusetyenziswa itekhnoloji ye-Smooth Overlay Modeling (FDM), kukho iindidi ezimbini eziphambili zabashicileli: iCartesian kunye neCoreXY, kunye nokugqibela okujoliswe kwabo bafuna ushicilelo olukhawulezayo lwezantya enkosi kubuchwephesha bobuchwephesha boqwalaselo lwentloko yesixhobo.Ubunzima obusezantsi bendibano yesibiyeli esezantsi ye-X/Y buthetha ukuba inokuhamba ngokukhawuleza, ikhuthaza abathanda i-CoreXY FDM ukuba balinge i-carbon fiber kunye nevidiyo [PrimeSenator] yamva nje apho i-X-beam isikwa kwi-aluminium ityhubhu kwaye inobunzima obungaphezulu kunoko obunokuthelekiswa nayo. .Iityhubhu zekhabhoni zefiber zikhaphukhaphu.
Ngenxa yokuba abashicileli be-CoreXY FDM bahamba kuphela kwicala le-Z elinxulumene nomphezulu woshicilelo, ii-axes ze-X/Y zilawulwa ngokuthe ngqo ngamabhanti kunye nedrive.Oku kuthetha ukuba ngokukhawuleza nangokuchaneka ngakumbi unokuhambisa intloko ye-extruder ecaleni kwezikhokelo zomgca, ngokukhawuleza onakho (ngokwethiyori) ukushicilela.Ukulahla i-carbon fiber enzima kakhulu kwezi zakhiwo ze-aluminiyam zigayiweyo kwi-Voron Design i-CoreXY umshicileli kufuneka uthethe inertia encinci, kwaye iidemos zokuqala zibonisa iziphumo ezilungileyo.
Yintoni enika umdla ngolu “shicilelo olukhawulezayo” loluntu kukuba ayisiyiyo kuphela isantya soshicilelo esikrwada, kodwa abashicileli beCoreXY FDM ngokwethiyori babagqwesa ngokuchaneka (isisombululo) kunye nokusebenza kakuhle (njengomthamo woshicilelo).Konke oku kwenza abashicileli bafanele ukuthathelwa ingqalelo kwixesha elizayo xa uthenga umshicileli wesimbo se FDM.
Izikhokelo zomgca zenzelwe ukugoba kwi-flatness apho zifakwe khona.Oku kuthetha ukuba umzila wesitimela uya kugoba inxalenye efakwe kuyo ukuba inxalenye eqhotyoshelweyo ayiqinile ngokwaneleyo.Ukuba kwanele ukundikhathaza, andazi, andizange ndisebenzise izikhokelo zomgca ngaphambili.
Kukho abasebenzisi beVoron abazinikele kakhulu abasebenzisa iireyile ezinqamlezileyo kuphela ngaphandle kwenkxaso enye, ke ayisiyiyo eyona nkqubo ingqongqo ukuqhuba komnye woomatshini abaneziphumo ezilungileyo.
Inkqubo ye-CoreXY ihambisa intloko yayo kwiindlela ze-X kunye ne-Y.Umgca we-Z uphunyezwa ngokuhambisa umgangatho woshicilelo okanye i-gantry.Inzuzo kukuba ukunyakaza okufunekayo kwebhedi kuncitshisiwe, ekubeni ukunyakaza kwi-Z-axis kuhlala kuncinci kwaye kunqabile.
Njengoko omnye umgqali wabonisa (uhlobo), iireyili ezinqamlekileyo ngoku ziqala ukubonakala zinzima.Bendizibuza ukuba ingaba zingenziwa na ngento elula njenge boron?(yintoni enokonakala?)
Enyanisweni, ndiyakrokrela ukuba isisombululo esona sisisombululo asikokwahlula iincwadana ezisuka kwinkxaso.Umshicileli wam onexabiso eliphantsi kunye nowoyikekayo usebenzisa iperi yentsimbi njengesikhokelo kunye nenkxaso, kwaye ndiyathandabuza ukuba oluyilo lungakhuphisana nalo ngokomgangatho.(kodwa ngokuqinisekileyo hayi ukuchaneka kunye nokuqina)
Ukufakela iintonga zentsimbi eziqinileyo kwiikona ezichaseneyo kunokusebenza, kodwa kungekhona ngezikhokelo zebhola ezilungelelaniswayo.
Embindini womzila kukho imingxuma esikwe yijethi yamanzi abrasive ukunciphisa ubunzima.Yenza icala elingasemva kwicala lokungena ukwenzela ukuba ukusasazeka kwendalo kwejethi kudala i-cone encinci kwaye akukho mida ebukhali kwicala langaphambili ukwenzela ukuba ama-wipers esangweni (ukuba afakwe) angagxininisi okanye anqunywe.
Ziintsimbi nje eziqinileyo.Zikhuphe nje kwi-carbide.Amalungu ajikiweyo ukusuka kwizikhonkwane zegeyiji kwintsimbi eqinileyo eyi-52100.
Akunakwenzeka njengoko ukwenziwa lukhuni kwe-induction ngexesha lokwenziwa kudala uxinzelelo lwangaphakathi kuloliwe (ezinye iileyili ze-magnesium alloy yaseTshayina zisenokungaqini tu ukuba zenziwe ngoomatshini).ulawulo……
Ngapha koko, ayilonkxaso ifanelekileyo yeereyile ezihambelanayo.Kwimivalo yentsimbi efakwe kwi-aluminiyam jonga kwii-rails ze-Nadella, le yingcamango kodwa ekubeni i-aluminiyam idinga icandelo elikhulu lomnqamlezo ukuze libe nokuqina kobunzima.
Inkampani yaseJamani i-FRANKE ivelisa iileyili ze-aluminium ezinamacala e-4 kunye ne-raceways yensimbi edibeneyo - ilula kwaye inamandla, umzekelo:
Ukuqina komqadi kuyanda kunye nesikwere sendawo.I-aluminiyam yinto yesithathu ekhaphukhaphu kwaye eyesithathu inamandla.Ukunyuka okuncinci kwicandelo kungaphezulu kokwaneleyo ukuhlawulela ilahleko kumandla wezinto eziphathekayo.Ngokwesiqhelo isiqingatha sobunzima sikunika umqadi oqina kancinane.
Ukusebenzisa i-surface grinder, iileyili zinokuncitshiswa kwi-H-shape kunye ne-web ye-sidewall phakathi kweeplani zoqhagamshelwano zeebhola (mhlawumbi zine-4 point contact, kodwa ufumana ingcamango).I-TIL: Iiprofayili ze-Titanium (alloy) zikwakhona: https://www.plymouth.com/products/net-and-near-net-shapes/ kodwa kuya kufuneka ubuze ixabiso.
Kwabe kukho ingxaki ngePlymouth Tube Inkampani yaseMelika lol.Emva kokujonga nge-virustotal, zonke iimvavanyo azizange zibonise iingxaki, ngaphandle kwe "Yandex Safe Browsing", leyo, ngokombono wakhe, iqulethe i-malware.
Ndikwacinga ukuba iireyile zomgca zijongeka zinzima kwaye ndiyawuthanda umbono weereyile zentsimbi ezidityanisiweyo.Ndiyathetha, oku kungenxa ye-3DP, kungekhona i-grinder - unokulahlekelwa ubunzima obuninzi.Okanye sebenzisa iurethane/amavili eplastiki kwaye ukhwele ngqo kwialuminiyam?
Masithembe ukuba akukho mntu uzama ukuyakha ngaphandle kweBeKukho uluvo olunomdla kuphononongo lwevidiyo malunga nokusetyenziswa kwe-carbon fiber.Ngoku khawucinge umatshini we-axis we-5-6 onokuthi ujikeleze i-3D eprintiweyo mandrel kwi-orientation ephuculweyo.Ayikwazanga ukufumana ulwazi oluninzi malunga neprojekthi yokujija iCF… mhlawumbi kunjalo?https://www.youtube.com/watch?v=VEGMEFynPKs
Awuzange uyifunde ngononophelo, kodwa ngaba umzila ngokwawo awunamandla ngokwaneleyo?Ngaba ngokwenene ufuna into engaphezulu nje kwesibiyeli sekona sokuncamathelisa ii-handrails kwiintsimbi ezisecaleni?
Ingcinga yam yokuqala yayikukusika ubunzima ngesiqingatha kwakhona ngokujika oonxantathu ngaphandle kweekona endaweni yeetyhubhu, kodwa ulungile...
Ngaba bubungqongqo obunjalo obufunekayo kwesi sicelo?Ukuba kunjalo, phakamisa i-bracket "ngaphakathi" kwikona, mhlawumbi kunye nezikrufu ezisetyenziselwa iileyili.
FYI: Ndifumene le vidiyo iluncedo kwimithetho yesithupha kwiimilo ezahlukeneyo zezakhiwo: https://youtu.be/cgLnADEfm6E
Ndicinga ukuba awunawo umatshini wokungqusha ungaphambana ngomatshini wokomba kwaye ubhore nje ubukhulu obahlukeneyo bemingxuma kwaye usondele kakhulu kuyo.
Oku, ngokuqinisekileyo, kukunyanzeliswa okungaqhelekanga ("kodwa kutheni?" Akuzange kube ngumbuzo osebenzayo kwi-HaD), kodwa kunokongezwa ngakumbi (kuququzelelwe) nge-algorithm yemfuzo ukuphuhlisa eyona nxalenye isebenzayo.Unokuba neziphumo ezingcono ukuba usebenzisa isitokhwe esiqinileyo kwaye usivumele ukuba sisike kube kanye kwi-X-axis kwaye kube kanye kwi-Y-axis.
Ndiyazi ukuba ubuchule be-bioevolution bungumsindo ngoku, kodwa bendiya kufuna iifractals kuba zijongeka ngokwesayensi kwaye azithembeli kuqikelelo oluphindaphindiweyo.… Ngoku esi inokuba sisikolo esidala njengoko sisibiza njalo, iFractal Punk 90- X?
Ndicinga ukuba iindleko zokusebenzisa izinto eziqinileyo ziya kudlula kude naziphi na izibonelelo.Ugalele phantsi uninzi lwemathiriyeli, eya kuyenza ibe nkulu kakhulu.
Kutheni uthatha inguqu kwi-hard stocks?Iindlela ezinomdla zokuphucula zinokusetyenziswa kwiityhubhu zesikwere.
Kwakhona, ukuya kuthi ga kufezekiso lombhobho osisikwere, ndicinga ukuba uyakufumana utshintsho oluncinci kakhulu kumgangatho.Oonxantathu kwi-truss sele belungile, iindawo zokunamathisela ziphuculwe ngakumbi kwezobuchwepheshe.Ukuba uguqulela oku kumbuzo othi "loluphi uyilo olulungileyo kwesi sicelo" (njengohlalutyo olupheleleyo lwesakhiwo somshicileli we-3D okanye into), ngoko ke ewe, ungafumana ngokuqinisekileyo iindawo zokunciphisa ubunzima.
Eyona ndlela ifikelelekayo yokwandisa itopology.Ndidlale kuphela ngale nto kwiSolidWorks, kodwa ndicinga ukuba kukho iiplagi zokwenza oku ngeFreeCAD.
Emva kokubukela ividiyo, kukho ezinye (ngokomlinganiselo) iziphumo ezifikelelekayo ezifuna ukuphuculwa ngakumbi (nangona, njengomnini womatshini weCore-XY, mna ngokwam andiboni mdla kulo mngxuma womvundla):
-Usondeze uloliwe kufutshane necala ukwenzela ukuqina okungcono (okwangoku uzakufumana ukuphambukiswa okukhulu komqadi kunye nokuphambuka kwestrat exhonywe kuyo)
-I-Classical truss optimization: Uyilo lwetruss aluzange luphuculwe, kwaye nangaphandle kwemigudu yokuphumeza izixhobo eziphuculweyo, uyilo lwetruss yintsimi ephuhliswe kakhulu.Emva kokufunda iincwadi zoyilo lwebhulorho, mhlawumbi unokunciphisa ubunzima ngesinye kwisithathu ngaphandle kokulahlekelwa ukuqina.
Ngelixa ekusebenzeni sele ilula kakhulu (kwaye ibonakala iqinile ngokwaneleyo ukuba ingachaphazeli ukuphindaphinda), andiyiboni ingongoma ekuyiphuculeni ngakumbi, ubuncinane ngaphandle kokujongana nengxaki yobunzima bomzila kaloliwe (njengoko abanye abantu besitsho).
“Ekuba efunde iincwadi zokuyila ibhulorho, usenokunciphisa ubunzima ngesinye isithathu ngaphandle kokuncama ukuqina.”
Sika *ubunzima*?Ndiyavuma ukuba mhlawumbi wongeze *amandla*, kodwa ubunzima obungaphezulu buvela phi?Uninzi lwentsimbi eseleyo isetyenziselwa iileyili, hayi iitrasi.
Sebenzisa izikrufu ze-aluminiyam ezifanayo ezisetyenziswa ngabathandi be-RC kwaye uhlahlele izikhokelo zemigca ukuze ukwazi ukucheba iigram ezimbalwa.
Ewe, kwaye ngendlela, kwiforum yeemoto malunga neminyaka elishumi edlulileyo kwafunyaniswa ukuba ukuzalisa imibundu nge-foam kunokunyusa kakhulu ukuqina kwezinye iimoto (ukuphucula ukuphatha, njl.)
Ngoko ke inokuba luluvo ukuzama ukusebenzisa ityhubhu eludongeni olucekeceke kakhulu, mhlawumbi yebrazed, brazed, brazed okanye ipleyiti yokukhwela efanayo ezaliswe ngamagwebu akhulayo.
Oku kufuneka kucace, kodwa ngokuqinisekileyo ufuna ukwenza naluphi na uhlobo lokutshisa, ukunyibilika, ukufudumeza, ukufudumeza, iintlobo ezishushu ngaphambi kokuba i-foam igcwalise.
Ishishini le-aerospace lifana neepaneli ze-honeycomp composite.I-carbon fiber encinci kakhulu okanye umzimba we-aluminium kunye nesakhiwo esiqhelekileyo se-Kevlar ye-honeycomb phakathi.Iqinile kakhulu kwaye ilula kakhulu.
Andiqondi ukuba imibhobho yodonga olucekethekileyo yindlela emayihambe.Andizange ndibe ngumlandeli omkhulu we-CFRP eyenziwe ngenaliti (iphulukana nezinto ezininzi ezilungileyo ze-UD CFRP, ebude obuyi-avareji yobude be-filament obunika amandla amakhulu), kwaye i-aluminiyam ayidli ngokuthengiswa ibhitye ngokwaneleyo ukuze igcinwe. ubunzima kakhulu.Ndiyacinga ukuba kuyakwenzeka ukuyicola kakuhle, kodwa ukunkqonkqoza kunokuthintela ukucola ngokwaneleyo.
Ukuba bendisiya kwelo cala, bendiza kuthabatha iphepha elicekethekileyo le-CFRP ye-bi-directional ukusuka kwenye yeendawo endizithandayo zemveliso yohlahlo lwabiwo-mali, ndiyinqumle ibe yisayizi, kwaye ndiyincamathelise kwi-foam yeseli evaliweyo, mhlawumbi ndiyisongele kumaleko weCFRP okanye i-fiberglass. .Oku kuya kuyinika ukuqina ngakumbi kwintshukumo kunye nenkxaso ye-printhead shafts, kwaye i-wrapper iya kuyinika ukuqina okwaneleyo kokuqina ukuze imelane nayo nayiphi na imizuzwana emincinci ephuma kwi-printhead.
Ndiwuqhwabela izandla umzamo kunye nobukrelekrele, kodwa andikwazi kuzibamba kodwa ndivakalelwa kukuba yinkcitho yamandla ndizama ukucudisa ithontsi ngalinye lokugqibela kuyilo olungalungiselelwanga ikamva kwaphela.Ekuphela kwendlela enokwenzeka ukuya phambili bubunzima obunxuseneyo be-3D yoshicilelo ukunciphisa amaxesha oshicilelo.Nje ukuba umntu aqhekeze zonke ezi ziyilo, akuyi kubakho khuphiswano.
Kodwa ndicinga ngokwembono yolwakhiwo mhlawumbi ngumba omkhulu - amandla e-carbon fiber ikakhulu kwezo zitya zinde zigqunywe ngokupheleleyo kwaye uzisike zonke ukuze uzenze zibe khaphukhaphu kwaye awusebenzisi ngendlela efanayo ukuqinisa- ngoku. ukwenza "umbhobho" okanye i-CF truss eluka apho uyidinga khona, isebenza kwicala elichanekileyo, iya kuba yinto enomdla kakhulu njengoko bane-router ye-CNC apho banokukrola intloko ye-extrusion.
Ukuzama ukufumana i-compromise phakathi kokwenza oko ukuthethayo (yeyona ndlela ingcono) kunye nokuthatha indlela elula ye-DIY yenye yeengxabano zokusebenzisa oko ngamanye amaxesha kuthiwa yi-carbon fiber.Kodwa ndicinga ukuba ndifumene umbono wokuzama ubume obusisiseko obufanayo, kuphela kwi-Zr magnesium alloy (okanye enye ialloy ye-magnesium ephezulu).Iialloyi ezilungileyo ze-magnesium zinamandla aphezulu kumlinganiselo wobunzima kune-aluminium.Azisekho "zomelele" njenge-carbon fiber ukuba ndikhumbula ngokuchanekileyo, kodwa zinzima kakhulu, endicinga ukuba ziya kwenza umehluko kwesi sicelo.
Ndiyathandabuza ukuba ngenene “ikhaphukhaphu kunethayibhu ye-carbon fiber” – ndithetha ukuba luhlobo lwefayibha yekhabhoni, yomelele kwaye ikhaphukhaphu kunemathiriyeli efana ne-aluminiyam.
Sasebenzisa iityhubhu ezimbalwa zeCF kwiprojekthi eyayi (ngokoqobo) iphepha elicekethekileyo kwaye lomelele kakhulu kunokulingana okutyebileyo, ubunzima be-aluminiyam, akukhathaliseki nokuba mingaphi imingxunya yesantya ofuna ukuyongeza.
Ndicinga ukuba mhlawumbi “kuba ndinako”, “kuba ikhangeleka ipholile”, mhlawumbi “kuba andinako ukuthenga ityhubhu yeCF” okanye mhlawumbi “ngenxa yokuba siyenza ngetyhubhu eyahlukileyo/engafanelekanga CF Thelekisa imigaqo.
Chaza “Omelele ngakumbi” – njengegama, lihambelana nomxholo, ngaba ngokwenene ujonge ukuqina, ukomelela kwemveliso, njl.njl.?
