Asalin asali an ƙirƙira shi azaman hanyar saurin samfuri,3D bugu, wanda kuma aka sani da masana'anta ƙari, ya samo asali zuwa tsarin ƙira na gaskiya. Firintocin 3D suna ba injiniyoyi da kamfanoni damar samar da samfuran samfuri da ƙarshen amfani a lokaci guda, suna ba da fa'idodi masu mahimmanci akan hanyoyin masana'antu na gargajiya. Wadannan abũbuwan amfãni sun haɗa da ba da damar gyare-gyaren taro, haɓaka 'yancin ƙira, ƙyale don rage taro kuma za'a iya amfani dashi azaman tsari mai mahimmanci don ƙananan samar da tsari.
Don haka menene bambance-bambance tsakanin fasahar bugu na 3D da na gargajiya da aka kafa na yanzuHanyoyin CNC?
1 - Bambance-bambancen kayan aiki
Babban kayan da ake amfani da su don bugu na 3D sune ruwa guduro (SLA), nailan foda (SLS), karfe foda (SLM) da waya (FDM). Resins na ruwa, foda na nailan da foda na ƙarfe sune mafi yawan kasuwa don buga 3D na masana'antu.
Abubuwan da aka yi amfani da su don injinan CNC duk nau'in ƙarfe ne guda ɗaya, waɗanda aka auna su ta tsawon, faɗi, tsayi da lalacewa na ɓangaren, sannan a yanke zuwa girman da ya dace don sarrafawa, zaɓin kayan injin CNC fiye da bugu na 3D, kayan aiki na gabaɗaya da filastik. sheet karfe za a iya CNC machined, da yawa daga cikin kafa sassa ne mafi alhẽri daga 3D bugu.
2 - Bambance-bambance a cikin sassa saboda ƙa'idodin gyare-gyare
Buga 3D shine aiwatar da yanke samfuri zuwa maki N yadudduka / N sannan tara su a jere, Layer by Layer / bit by bit, kamar ginin tubalan. Don haka bugu na 3D yana da tasiri wajen sarrafa hadaddun sassa na tsari kamar sassan kwarangwal, yayin da injinan CNC na sassan kwarangwal yana da wahala a cimma.
CNC machining ne m masana'antu, inda daban-daban kayan aiki da gudu a high gudun yanke sassa da ake bukata bisa ga shirye-shiryen kayan aiki. Saboda haka, CNC machining za a iya kawai sarrafa tare da wani mataki na curvature na taso keya sasanninta, m dama kusurwa CNC machining ba matsala, amma ba za a iya kai tsaye machined daga ciki dama kwana, da za a samu ta hanyar waya yankan / EDM. da sauran matakai. Bugu da kari, don lankwasa saman, CNC machining na lanƙwasa saman yana cin lokaci kuma yana iya barin layukan da ake iya gani cikin sauƙi a ɓangaren idan shirye-shirye da ma'aikatan aiki ba su da isasshen. Don sassan da ke da kusurwoyin dama na ciki ko fiye da wurare masu lanƙwasa, bugu na 3D ba shi da wahala ga na'ura.
3 – Bambance-bambance a cikin software mai aiki
Yawancin software na slicing don bugun 3D yana da sauƙi don aiki kuma a halin yanzu an inganta shi don zama mai sauƙi kuma ana iya samar da tallafi ta atomatik, wanda shine dalilin da ya sa 3D za a iya yadawa ga masu amfani da su.
Software na shirye-shirye na CNC ya fi rikitarwa kuma yana buƙatar ƙwararru don sarrafa ta, tare da ma'aikacin CNC don sarrafa injin CNC.
4 - CNC shirye-shiryen aiki shafi
Wani bangare na iya samun zaɓuɓɓukan injina na CNC da yawa kuma yana da matukar wahala ga shirin. 3D bugu, a gefe guda, yana da sauƙi mai sauƙi kamar yadda jeri na ɓangaren yana da ƙananan tasiri akan lokacin sarrafawa da abubuwan amfani.
5 – Bambance-bambancen da ake samu a bayan aiwatarwa
Akwai 'yan post-aiki zažužžukan ga 3D bugu sassa, kullum sanding, ayukan iska mai ƙarfi, deburring, rini, da dai sauransu Bugu da kari ga sanding, mai ayukan iska mai ƙarfi da deburring, akwai kuma electroplating, siliki-screening, kushin bugu, karfe hadawan abu da iskar shaka, Laser engraving. , fashewar yashi da sauransu.
A taƙaice, CNC machining da 3D bugu suna da nasu amfani da rashin amfani. Zaɓin mashin ɗin da ya dace ya fi mahimmanci.
