Prototyping ndi lingaliro labwino kuyesa kapangidwe kanu musanapange mtundu wokonzekera kupanga. 3D Printers ndi CNC Machining ndi njira zomwe zingatheke, koma iliyonse ili ndi ubwino wake ndi zolepheretsa kutengera magawo osiyanasiyana a polojekiti. Ndiye njira yabwino ndi iti? Ngati muli mu conundrum iyi, ndiye kuti nkhaniyi ndi zomwe mukufuna. Tizama m'matekinoloje onse awiri ndikukambirana zinthu zambiri zofunika kukuthandizani kusankha zomwe zili bwino kutengera zosowa zanu.
Mu positi iyi tikambirana:
Kusindikiza kwa 3D vs. CNC Machining: Pali Kusiyana Kotani?
Tisanadumphire mwatsatanetsatane, kugwira bwino pazoyambira ndikwabwino. Kusiyana kwakukulu pakati pa kusindikiza kwa 3D ndi CNC Machining ndi momwe chomaliza chimafikira.
Kusindikiza kwa 3D ndi njira yopangira zowonjezera. Izi zikutanthauza kuti chomalizacho chimapangidwa ndi chosindikizira cha 3D chomwe chimayika zigawo zotsatizana za zinthu pa mbale yogwirira ntchito mpaka mawonekedwe omaliza a malondawo akwaniritsidwa.
CNC Machining, Komano, ndi njira yochotsera. Mumayamba ndi chipika cha zinthu zomwe zimatchedwa chopanda kanthu ndi makina kutali kapena kuchotsa zinthu kuti zisiyidwe ndi chinthu chomaliza.
Kodi mungasankhire bwanji zomwe zili zabwino pazofuna zanu?
Chilichonse mwa njira ziwiri zopangira zimakhala ndi ubwino wake pazochitika zinazake. Tiyeni tione aliyense payekhapayekha.
1. Nkhani
Pogwira ntchito ndi zitsulo, CNC Machines kukhala ndi ubwino womveka. Kusindikiza kwa 3D kumayang'ana kwambiri mapulasitiki. Pali matekinoloje osindikizira a 3D omwe amatha kusindikiza zitsulo, koma potengera mawonekedwe, amatha kukhala okwera mtengo kwambiri chifukwa makina amakampaniwo amatha kupitilira $100,000.
Choyipa china chokhala ndi zitsulo zosindikizira za 3D ndikuti kumapeto kwanu sikumveka bwino ngati gawo lomwelo lopangidwa ndi mphero yopanda kanthu. Mutha kupititsa patsogolo mphamvu ya gawo lachitsulo losindikizidwa la 3D pochiritsa kutentha, zomwe zingapangitse kuti mtengo wonse uwonjezeke. Ponena za ma superalloys ndi TPU, muyenera kupita ndi kusindikiza kwa 3D.
2. Ma voliyumu opanga ndi mtengo
Ngati mukuyang'ana ma prototypes ofulumira kapena ma voliyumu otsika (otsika kawiri), ndiye kuti kusindikiza kwa 3D ndikotsika mtengo. Pakupanga ma voliyumu apamwamba (madijiti okwera awiri mpaka mazana angapo), mphero ya CNC ndiyo njira yopitira.
Mitengo yapatsogolo yopangira zowonjezera nthawi zambiri imakhala yotsika kuposa kupanga kocheperako pama prototypes amodzi. Izi zikunenedwa, magawo onse omwe safuna ma geometri ovuta amatha kupangidwa motsika mtengo pogwiritsa ntchito makina a CNC.
Ngati mukuyang'ana kuchuluka kwa mayunitsi opitilira 500, matekinoloje achikhalidwe monga kuumba jekeseni ndiwotsika mtengo kuposa njira zopangira zowonjezera komanso zochepetsera.
3. Kusokonezeka kwapangidwe
Matekinoloje onsewa ali ndi malire, koma munkhaniyi, kusindikiza kwa 3D kuli ndi mwayi wowonekera. Makina a CNC sangathe kuthana ndi ma geometri ovuta chifukwa cha zinthu monga kupeza zida ndi chilolezo, zonyamula zida, ndi malo okwera. Simungathenso kupanga ngodya zazikuluzikulu chifukwa cha zida za geometry. Kusindikiza kwa 3D kumapangitsa kusinthasintha kochulukirapo pankhani ya geometry yovuta.
Chinthu china choyenera kuganizira ndi kukula kwa gawo lomwe mukujambula. Makina a CNC ndi oyenera kugwira ntchito zazikulu. Osati kuti kulibe osindikiza a 3D kunja uko omwe sali akulu mokwanira, koma kuchokera kumalingaliro a prototyping, ndalama zomwe zimagwirizanitsidwa ndi chosindikizira chachikulu cha 3D zimawapangitsa kukhala osatheka kugwira ntchitoyo.
4. Kulondola kwenikweni
Kwa magawo omwe amafunikira kulolerana kolimba, makina a CNC ndi chisankho chodziwikiratu. CNC mphero imatha kukwaniritsa kulolerana pakati pa ± 0.025 - 0.125 mm. Nthawi yomweyo, osindikiza a 3D nthawi zambiri amakhala ndi kulolerana kwa ± 0.3 mm. Kupatula osindikiza a Direct Metal Laser Sintering (DMLS) omwe amatha kulolerana mpaka ± 0.1 mm, ukadaulo uwu ndiwokwera mtengo kwambiri pakujambula.
5. Kumaliza pamwamba
CNC Machining ndi chisankho chodziwikiratu ngati kumalizidwa kwapamwamba kwambiri ndikofunikira. Makina osindikizira a 3D amatha kukwanira bwino ndikumaliza, koma CNC Machining ndi njira yopitira ngati mukufuna kumaliza kwapamwamba kwambiri kuti mugwirizane ndi magawo ena olondola kwambiri.
Buku Losavuta Lokuthandizani Kusankha
Nawa kalozera wachangu kukuthandizani kusankha pakati pa 3D yosindikiza ndi CNC Machining:
- Ngati mukuyang'ana ma prototyping othamanga, omwe amaphatikiza ma geometry ovuta a prototype imodzi kapena kupanga kochepa kwambiri, ndiye kuti kusindikiza kwa 3D kudzakhala chisankho chabwino.
- Ngati mukuyang'ana kutulutsa kwakukulu kwa magawo mazana angapo okhala ndi ma geometries osavuta, pitani ndi makina a CNC.
- Ngati tiyang'ana pakugwira ntchito ndi zitsulo, ndiye kuti pakuwona mtengo, makina a CNC ali ndi ubwino. Izi zimagwira ngakhale zocheperako. Komabe, malire a geometry akugwirabe ntchito pano.
- Ngati kubwerezabwereza, kulolerana kolimba, ndi kumaliza kwabwino kwapamwamba kumayikidwa patsogolo kwambiri, pitani ndi makina a CNC.
Mawu Otsiriza
Kusindikiza kwa 3D ndikadali ukadaulo watsopano, ndipo nkhondo yake yolamulira msika idangoyamba kumene. Inde, pali makina osindikizira a 3D okwera mtengo komanso apamwamba omwe achepetsa kusiyana kwa zomwe CNC Machining amatha, koma kuchokera pamalingaliro a prototyping, sangaganizidwe pano. Palibe mtundu umodzi wokwanira yankho lonse. Kusankha imodzi kutengera imzake zimatengera momwe polojekiti yanu imapangidwira.
