Zikafika pakusindikiza kwa 3D pogwiritsa ntchito ukadaulo wa Smooth Overlay Modeling (FDM), pali magulu awiri akulu a osindikiza: Cartesian ndi CoreXY, ndipo omalizawo amayang'ana omwe akufuna kusindikiza mwachangu kwambiri chifukwa chaukadaulo wosinthika wa zida zosinthira.Kutsika kochepa kwa gulu la X/Y pansi pa bulaketi kumatanthauza kuti imathanso kuyenda mwachangu, zomwe zimapangitsa okonda CoreXY FDM kuyesa mpweya wa carbon ndi kanema waposachedwa wa [PrimeSenator] pomwe X-beam imadulidwa ku chubu cha aluminiyamu ndikulemera kuposa kufananiza. .Machubu a carbon fiber ndi opepuka.
Chifukwa osindikiza a CoreXY FDM amangosunthira mbali ya Z yokhudzana ndi malo osindikizira, nkhwangwa za X/Y zimayendetsedwa mwachindunji ndi malamba ndi ma drive.Izi zikutanthauza kuti mofulumira komanso molondola mungathe kusuntha mutu wa extruder pamodzi ndi maupangiri a mzere, mofulumira momwe mungathere (mwachidziwitso) kusindikiza.Kugwetsa kaboni wolemera kwambiri pazipangidwe za aluminiyamu zogayidwa pa chosindikizira cha Voron Design CoreXY kuyenera kutanthauza kuchepa kwamphamvu, ndipo ma demo oyambirira akuwonetsa zotsatira zabwino.
Chosangalatsa pagulu la "kusindikiza mwachangu" ndikuti sikuti ndi liwiro losindikiza lokha, koma osindikiza a CoreXY FDM amawaposa molondola (kutsimikiza) komanso kuchita bwino (monga voliyumu yosindikiza).Zonsezi zimapangitsa osindikizawa kukhala oyenera kuganizira nthawi ina mukadzagula chosindikizira chamtundu wa FDM.
Ma Linear Guide amapangidwa kuti azipindika kumtunda komwe amayikidwa.Izi zikutanthauza kuti njanjiyo idzapindika mbali yomwe imamangiriridwako ngati gawo lomwe amangirizidwako silili lolimba mokwanira.Ngati ndizokwanira kundidetsa nkhawa, sindikudziwa, sindinagwiritsepo ntchito maupangiri amzere.
Pali ogwiritsa ntchito Voron odzipatulira omwe amangogwiritsa ntchito njanji zofananira popanda chithandizo china, kotero si njira yolimba kwambiri yoyendetsera makina omwe ali ndi zotsatira zabwino.
Dongosolo la CoreXY limasuntha mutu wake munjira za X ndi Y.The Z axis imatheka posuntha zosindikiza kapena gantry.Ubwino wake ndikuti kusuntha kofunikira kwa bedi kumachepetsedwa, chifukwa mayendedwe a Z-axis nthawi zonse amakhala aang'ono komanso osawerengeka.
Monga momwe ndemanga ina inafotokozera (mtundu wa), njanji zozungulira tsopano zayamba kuwoneka zolemetsa.Ndinali kudabwa ngati angapangidwe kuchokera ku chinthu chopepuka ngati boron?(chingachitike nchiyani?)
M'malo mwake, ndikukayikira kuti njira yabwino yothetsera vutoli sikulekanitsa mabukuwa ndi chithandizo.Chosindikizira changa chotsika mtengo komanso chowopsa chimagwiritsa ntchito ndodo zachitsulo monga chiwongolero ndi chothandizira, ndipo ndikukayika kuti kapangidwe kake kakhoza kupikisana nako muubwino.(koma osati kulondola komanso kukhazikika)
Kuyika ndodo zachitsulo zolimba m'makona opingasa kungagwire ntchito, koma osati ndi maupangiri opangidwa okonzeka obwereza.
Pakati pa njanji pali mabowo odulidwa ndi abrasive water jet kuti achepetse kulemera.Pangani mbali yakumbuyo mbali yolowera kotero kuti kufalikira kwachilengedwe kwa jet kumapanga kondomu kakang'ono komanso kopanda nsonga zakuthwa kumbali yakutsogolo kuti ma wipers pachipata (ngati atayikidwa) asagwedezeke kapena kudula.
Angokhala zitsulo zolimba.Ingowaperani ku carbide.Magawo otembenuzidwa kuchokera ku zikhomo za geji muzitsulo zolimba zokhala ndi 52100.
Zosatheka chifukwa kulimba kwa induction komwe kumagwiritsidwa ntchito popanga kumapangitsa kupsinjika kwamkati mu njanji (njanji zina zaku China za magnesium alloy sizingawumitsidwe nkomwe kuti zisamangidwe).management……
M'malo mwake, sichiri chithandizo choyenera cha njanji zozungulira.Kwa mipiringidzo yachitsulo yophatikizidwa mu aluminiyumu yang'anani pa njanji za Nadella, ili ndi lingaliro koma popeza aluminiyumu imafunikira gawo lalikulu la mtanda kuti ikhale yolimba kwambiri.
Kampani yaku Germany FRANKE imapanga njanji za aluminiyamu za 4 zokhala ndi mayendedwe azitsulo ophatikizika - opepuka komanso amphamvu, mwachitsanzo:
Kuuma kwa mtengo kumawonjezeka ndi lalikulu la dera.Aluminiyamu ndi chowunikira chachitatu ndi chachitatu champhamvu.Kuwonjezeka pang'ono kwa gawo ndikokwanira kulipira kutayika kwa mphamvu zakuthupi.Nthawi zambiri theka la kulemera kwake limakupatsani mtengo wolimba pang'ono.
Pogwiritsa ntchito chopukusira pamwamba, njanji zimatha kuchepetsedwa kukhala mawonekedwe a H ndi ukonde wam'mbali pakati pa ndege zolumikizana ndi mipira (mwina zimakhala ndi kukhudzana kwa 4, koma mumapeza lingaliro).TIL: Mbiri ya Titanium (alloy) iliponso: https://www.plymouth.com/products/net-and-near-net-shapes/ koma muyenera kufunsa mtengo.
Ndiye panali vuto ndi Plymouth Tube Company of America lol.Pambuyo pofufuza ndi virustotal, mayesero onse sanawonetsere mavuto, kupatulapo "Yandex Safe Browsing", yomwe, m'malingaliro ake, inali ndi pulogalamu yaumbanda.
Ndikuganizanso kuti njanji zozungulira zimawoneka zolemetsa ndipo ndimakonda lingaliro lazitsulo zophatikizika zachitsulo.Ndikutanthauza, izi ndi za 3DP, osati chopukusira - mukhoza kutaya kulemera kwakukulu.Kapena gwiritsani ntchito mawilo a urethane/pulasitiki ndikukwera molunjika pa aluminiyamu?
Tiyeni tiyembekezere kuti palibe amene akuyesera kuti apange kuchokera ku BePali ndemanga yosangalatsa mu ndemanga ya kanema yokhudza kugwiritsa ntchito mpweya wa carbon.Tsopano lingalirani makina olamulira a 5-6 omwe amatha kukulunga mandrel osindikizidwa a 3D mumayendedwe okometsedwa.Sindinathe kupeza zambiri za projekiti yokhotakhota ya CF… mwina ndi choncho?https://www.youtube.com/watch?v=VEGMEFynPKs
Simunayiphunzire mosamala, koma kodi njanjiyo siili yolimba mokwanira?Kodi mumafunadi china choposa cholumikizira chapakona chomangirira njanji zam'mbali?
Lingaliro langa loyamba linali kudulanso pakati pa theka ndikutembenuza makona atatu kuchokera kumakona m'malo mwa machubu, koma mukulondola ...
Kodi kukhazikika kwapang'onopang'ono kotereku kumafunikira pakugwiritsa ntchito?Ngati ndi choncho, ikani bulaketi "mkati" pakona, mwinamwake ndi zomangira zomwe zimagwiritsidwa ntchito popanga njanji.
FYI: Ndapeza vidiyoyi kukhala yothandiza pamalamulo apamanja pamapangidwe osiyanasiyana: https://youtu.be/cgLnADEfm6E
Ndikuganiza kuti ngati mulibe makina amphero mutha kuchita misala ndi makina obowola ndikungobowola mabowo osiyanasiyana ndikuyandikira kwambiri.
Izi, ndithudi, ndizovuta zachilendo ("koma bwanji?" Si funso lovomerezeka mu HaD), koma likhoza kukonzedwanso (kuthandizidwa) ndi ma genetic algorithm kuti apange gawo lothandiza kwambiri.Mutha kukhala ndi zotsatira zabwino ngati mutagwiritsa ntchito zolimba ndikuzilola kuti zidulidwe kamodzi mu X-axis ndipo kamodzi mu Y-axis.
Ndikudziwa kuti njira za bioevolution ndizovuta pakali pano, koma ndimakonda fractals chifukwa amawoneka asayansi kwambiri ndipo sadalira kubwerezabwereza.… Tsopano iyi ikhoza kukhala sukulu yakale monga momwe timatchulira, Fractal Punk 90- X?
Ndikuganiza kuti mtengo wogwiritsa ntchito chinthu cholimba udzaposa phindu lililonse.Mwathira mchenga pansi zinthu zambiri, zomwe zipangitsa kuti zikhale zazikulu.
N'chifukwa chiyani muyenera kusintha ku hard stock?Njira zokometsera zosangalatsa zitha kugwiritsidwabe ntchito pamachubu akulu.
Komanso, kukhathamiritsa kwa mapaipi a square kumapita, ndikuganiza kuti mupeza kusintha kochepa kwambiri.Makona atatu mu truss ali kale mulingo woyenera, mfundo zomata ndi zapamwamba kwambiri paukadaulo.Ngati mungatanthauzire funso la "mapangidwe otani omwe ali abwino kwambiri pakugwiritsa ntchito" (monga kusanthula kwatsatanetsatane kwa chosindikizira cha 3D kapena china), ndiye inde, mutha kupeza malo oti muchepetse kulemera.
Njira yokwaniritsira yokwaniritsika ndiyo kukhathamiritsa kwa topology.Ndangosewera ndi izi mu SolidWorks, koma ndikuganiza kuti pali mapulagini ochita izi ndi FreeCAD.
Nditawonera kanemayo, pali zotsatira (zochepera) zomwe zingapezeke mosavuta zomwe zimafunikira kukhathamiritsa kwina (ngakhale, monga mwini makina a Core-XY, ine ndekha sindikuwona chidwi ndi dzenje la kalulu):
- Anasunthira njanji pafupi ndi mbali kuti ikhale yolimba bwino (pakadali pano ikumana ndi kupindika kwakukulu kwa mtengowo komanso kupatuka kwa chingwe chomwe chidayikidwapo)
- Kukhathamiritsa kwapamwamba kwa truss: Mapangidwe a truss truss sanakwaniritsidwe, ndipo ngakhale popanda kuyesetsa kukhazikitsa zida zotsogola, mapangidwe a truss ndi gawo lotukuka kwambiri.Pambuyo powerenga mabuku opangira mlatho, amatha kuchepetsa kulemera kwake ndi gawo lina lachitatu popanda kutaya kuuma .
Ngakhale muzochita ndizopepuka kale (ndipo zikuwoneka zowuma mokwanira kuti sizingakhudze kubwerezabwereza), sindikuwona mfundo yoti ziwongolerenso, osachepera popanda kuthana ndi vuto la kulemera kwa njanji (monga momwe anthu ena amanenera).
"Atawerenga mabuku opangira mlatho, atha kuchepetsa kulemera kwake ndi gawo limodzi mwa magawo atatu popanda kusiya kuuma."
Kudula *kulemera*?Ndikuvomereza kuti mwina anawonjezera *mphamvu*, koma kulemera kowonjezerako kunachokera kuti?Zambiri mwazitsulo zotsalazo zimagwiritsidwa ntchito popanga njanji, osati ma trusses.
Gwiritsani ntchito zomangira zomwezo za aluminiyamu zomwe okonda RC amagwiritsa ntchito ndi mchenga pansi pamizere mizere kuti mutha kumeta magalamu angapo.
O, ndipo mwa njira, pabwalo lamagalimoto pafupifupi zaka khumi zapitazo, zidapezeka kuti kudzaza mipata ndi thovu kumatha kukulitsa kulimba kwa magalimoto ena (kuwongolera kasamalidwe, ndi zina).
Chifukwa chake litha kukhala lingaliro kuyesa kugwiritsa ntchito chubu chopepuka chapakhoma chopepuka kwambiri, mwina ngati chotchingira, chonyezimira, chonyezimira kapena mbale yofananira yodzaza ndi thovu lokulirakulira.
Izi ziyenera kukhala zoonekeratu, koma ndithudi mukufuna kuchita mtundu uliwonse wa kutentha, kusungunuka, kutentha, kutentha, mitundu yotentha chithovu chisanadzaze.
Makampani opanga ndege amafanana ndi mapanelo a zisa.Woonda kwambiri wa carbon fiber kapena thupi la aluminiyamu lomwe lili ndi zisa za Kevlar pakati.Zokhazikika komanso zopepuka kwambiri.
Sindikuganiza kuti mipope yapakhoma yopyapyala ndiyo njira yopitira.Sindinayambe ndakonda kwambiri CFRP yopangidwa ndi jakisoni (imataya zabwino zambiri za UD CFRP, yomwe ndi kutalika kwa ulusi wautali womwe umapangitsa kuti ikhale yamphamvu kwambiri), ndipo aluminiyumu nthawi zambiri samagulitsidwa woonda kuti apulumutse. kulemera kwambiri.Ndikuganiza kuti ndizotheka kuchipera bwino kwambiri, koma kugogodako kungalepheretse kugaya mokwanira.
Ndikadapita mbali imeneyo, ndikadatenga chitsamba chopyapyala cha CFRP kuchokera pamasamba omwe ndimakonda kwambiri, ndikuchidula mpaka kukula, ndikumata ku thovu lotsekeka, mwina ndikulikulunga m'magulu a CFRP kapena fiberglass. .Izi zidzapangitsa kuti zikhale zolimba kwambiri mumayendedwe ndi zitsulo zothandizira printhead, ndipo chopukutiracho chidzapatsa kukhazikika kokwanira kuti athe kupirira mphindi zochepa zotuluka kuchokera pamutu wosindikizira.
Ndimayamika khama ndi nzeru, koma sindingathe kudzimva kuti ndikutaya mphamvu kuyesa kufinya dontho lililonse lomaliza la mapangidwe omwe sanapangidwe mtsogolo.Njira yokhayo yopitira patsogolo ndi kusindikiza kwakukulu kwa 3D kuti muchepetse nthawi yosindikiza.Munthu akabera mapangidwe onsewa, sipadzakhala mpikisano.
Koma ndikuganiza kuti malinga ndi kapangidwe kake ndi nkhani yayikulu - mphamvu ya kaboni fiber nthawi zambiri imakhala mu ulusi womwe umakhala wautali kwambiri ndipo mumadula zonse kuti zikhale zopepuka ndipo simugwiritsa ntchito njira yomweyo kulimbikitsa - tsopano. kupanga "chitoliro" kapena CF truss kuti yokhotakhota kumene muyenera izo, ntchito m'njira yoyenera, zingakhale wokongola chidwi monga ali CNC rauta kumene iwo kusema ndi extrusion mutu.
Kuyesera kupeza kugwirizana pakati pa kuchita zomwe mukunena (yomwe ndi njira yabwino kwambiri) ndi kutenga njira yosavuta ya DIY ndi imodzi mwa zifukwa zogwiritsira ntchito zomwe nthawi zina zimatchedwa carbon fiber.Koma ndikuganiza kuti ndili ndi lingaliro loyesera mawonekedwe omwewo, mu Zr magnesium alloy (kapena aloyi ena amphamvu kwambiri a magnesium).Ma aloyi abwino a magnesium ali ndi mphamvu zochulukirapo kuposa aluminium.Iwo sali "olimba" ngati carbon fiber ngati ndikukumbukira bwino, koma ndi owuma kwambiri, omwe ndikuganiza kuti apanga kusiyana kwa ntchitoyi.
Ndikukayika kuti ndi "opepuka kuposa machubu a kaboni fiber" - ndikutanthauza kuti ndi mtundu wa carbon fiber, wamphamvu komanso wopepuka kuposa zida ngati aluminiyamu.
Tidagwiritsa ntchito machubu ochepa a CF pulojekiti yomwe inali (kwenikweni) pepala lopyapyala komanso lamphamvu kwambiri kuposa aluminiyamu yokulirapo, yolemera kwambiri, mosasamala kanthu kuti mumafuna kuwonjezera mabowo angati othamanga.
Ndikuganiza kuti mwina ndi "chifukwa ndingathe", "chifukwa zikuwoneka bwino", mwina "chifukwa sindingakwanitse kugula chubu la CF" kapena "chifukwa tikuchita ndi chubu chosiyana kwambiri / chosayenera CF Fananizani miyambo.
Tanthauzirani "Wamphamvu" - ngati liwu, ndizokhazikika, kodi mukufunadi kuuma, kulimba, ndi zina zotero?
