He manaʻo maikaʻi ka prototyping e hoʻāʻo i kāu hoʻolālā ma mua o ka hana ʻana i kahi kumu hoʻohālike hoʻomākaukau. ʻO nā mea paʻi 3D a me ka CNC Machining he mau koho kūpono, akā loaʻa i kēlā me kēia mea nā pono a me nā palena ʻokoʻa e pili ana i nā ʻāpana papahana like ʻole. No laila ʻo wai ka koho maikaʻi? Inā ʻoe i loko o kēia conundrum, a laila ʻo kēia ʻatikala ka mea āu e pono ai. E luʻu hohonu mākou i nā ʻenehana ʻelua a kūkākūkā i nā kumu koʻikoʻi e kōkua iā ʻoe e hoʻoholo i ka mea maikaʻi loa e pili ana i kāu pono papahana.
Ma kēia pou e uhi mākou:
3D Printing vs. CNC Machining: He aha ka ʻokoʻa?
Ma mua o ko mākou lele ʻana i nā kikoʻī, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i nā kumu. ʻO ka ʻokoʻa mua ma waena o ka paʻi 3D a me ka CNC Machining ʻo ia ke ʻano o ka hopena hope loa.
ʻO ka paʻi 3D kahi hana hana hoʻohui. 'O ia ho'i, ua hana 'ia ka huahana hope e kekahi mea pa'i 3D e waiho ana i ka papa hana ma ka papa hana a hiki i ka loa'a 'ana o ke kinona hope o ka huahana.
ʻO ka CNC Machining, ma ka ʻaoʻao ʻē aʻe, he kaʻina hana subtractive. Hoʻomaka ʻoe me kahi poloka mea i kapa ʻia he blank a me ka mīkini a wehe paha i nā mea e waiho ʻia me ka huahana hope.
Pehea e koho ai i ka mea e pono ai kāu papahana?
Loaʻa i kēlā me kēia o nā ʻenehana hana ʻelua nā mea maikaʻi i nā hiʻohiʻona kikoʻī. E nānā kākou i kēlā me kēia.
1. Ka Mea Hana
I ka hana ʻana me nā metala, Nā Mīkini CNC loaa ka pomaikai maopopo. ʻOi aku ka manaʻo o ka paʻi 3D holoʻokoʻa i nā plastics. Aia nā ʻenehana paʻi 3D i hiki ke paʻi metala, akā mai ka manaʻo o ka prototyping, hiki ke kūʻai nui ʻia no ka mea hiki ke kūʻai ʻia kēlā mau mīkini ʻoihana ma luna o $100,000.
ʻO kahi ʻaoʻao ʻē aʻe me ka metala paʻi 3D ʻaʻole i like ke kani o kāu huahana hope e like me ka ʻāpana like i hana ʻia ma ka wili ʻana i kahi blank paʻa. Hiki iā ʻoe ke hoʻomaikaʻi i ka ikaika o kahi ʻāpana metala paʻi 3D ma o ka mālama ʻana i ka wela, hiki ke hoʻonui i ke kumukūʻai holoʻokoʻa. E pili ana i nā superalloys a me TPU, pono ʻoe e hele me ka paʻi 3D.
2. Ka nui o ka hana a me ka uku
Inā ʻoe e ʻimi nei i nā prototypes wikiwiki a i ʻole nā helu hana haʻahaʻa (helu pālua haʻahaʻa), a laila ʻoi aku ka liʻiliʻi o ka paʻi 3D. No nā hua kiʻekiʻe kiʻekiʻe (nā huahelu pālua kiʻekiʻe i kahi mau haneli), ʻo CNC wili ke ala e hele ai.
ʻOi aku ka haʻahaʻa o nā kumukūʻai mua o ka hana hoʻohui ʻana ma mua o ka hana subtractive no nā prototypes hoʻokahi. ʻO ka ʻōlelo ʻana, hiki ke hana ʻia nā ʻāpana āpau i koi ʻole i nā geometries paʻakikī ke hana ʻoi aku ka maikaʻi me ka hoʻohana ʻana i ka mīkini CNC.
Inā ʻoe e nānā ana i nā puke hana ma luna o 500 mau ʻāpana, ʻoi aku ka maikaʻi o nā ʻenehana hana kuʻuna e like me ka hoʻoheheʻe inject ma mua o nā ʻenehana hana additive a subtractive.
3. Paʻakikī Hoʻolālā
Loaʻa nā ʻenehana ʻelua i kā lākou mau palena, akā ma kēia ʻano, ʻoi aku ka maikaʻi o ka paʻi 3D. ʻAʻole hiki i ka mīkini CNC ke mālama i nā geometries paʻakikī ma muli o nā kumu e like me ka loaʻa ʻana o nā mea hana a me nā ʻae ʻana, nā mea paʻa, a me nā wahi kau. ʻAʻole hiki iā ʻoe ke mīkini i nā kihi huinahā ma muli o ka geometry mea hana. Hiki i ka paʻi 3D ke maʻalahi i ka wā e pili ana i ka geometry paʻakikī.
ʻO kekahi hiʻohiʻona e noʻonoʻo ai ʻo ka nui o ka ʻāpana āu e prototyping nei. ʻOi aku ka maikaʻi o nā mīkini CNC no ka mālama ʻana i nā ʻāpana nui. ʻAʻole ʻo ia ʻaʻohe mea paʻi 3D ʻaʻole lawa ka nui, akā mai kahi hiʻohiʻona prototyping, ʻo nā kumukūʻai pili me kahi paʻi 3D nui e hiki ʻole ai iā lākou no ka hana.
4. ʻOiaʻiʻo Dimensional
No nā ʻāpana e koi ai i ka hoʻomanawanui paʻa, ʻo CNC machining kahi koho maʻalahi. Hiki i ka milling CNC ke hoʻokō i nā pae hoʻomanawanui ma waena o ± 0.025 – 0.125 mm. I ka manawa like, loaʻa nā mea paʻi 3D ma kahi o ± 0.3 mm ka hoʻomanawanui. Koe wale no nā mea paʻi Direct Metal Laser Sintering (DMLS) hiki ke hoʻokō i ka hoʻomanawanui ma lalo o ± 0.1 mm, ʻoi aku ka pipiʻi o kēia ʻenehana no ka prototyping.
5. Hoʻopau i luna
ʻO ka mīkini CNC kahi koho maʻemaʻe inā he ʻano koʻikoʻi ka hoʻopau ʻana o ka ʻili. Hiki i nā mea paʻi kiʻi 3D ke hana i kahi kūpono maikaʻi a hoʻopau, akā ʻo CNC Machining ke ala e hele ai inā makemake ʻoe i kahi hoʻopau ʻili maikaʻi e hoʻopaʻa ʻia me nā ʻāpana ʻoi aku ka pololei.
He alakaʻi maʻalahi e kōkua iā ʻoe e koho
Eia ke alakaʻi wikiwiki e kōkua iā ʻoe e hoʻoholo ma waena o ka paʻi 3D a me ka mīkini CNC:
- Inā ʻoe e nānā nei i ka prototyping wikiwiki, e pili ana i ka geometry paʻakikī no kahi prototype hoʻokahi a i ʻole kahi hana liʻiliʻi loa, a laila ʻo ka paʻi 3D ke koho kūpono.
- Inā ʻoe e nānā nei i kahi hana kiʻekiʻe o kahi mau haneli mau ʻāpana me nā geometries maʻalahi, e hele me ka mīkini CNC.
- Inā mākou e nānā i ka hana ʻana me nā metala, a laila mai kahi hiʻohiʻona kumukūʻai, ʻoi aku ka maikaʻi o ka mīkini CNC. Paʻa kēia no nā mea liʻiliʻi. Eia naʻe, pili mau nā palena geometry ma ʻaneʻi.
- Inā makemake nui ʻia ka hoʻihoʻi hou ʻana, ka hoʻomanawanui ʻana, a me ka hoʻopau ʻana o ka ʻili maikaʻi, e hele me ka CNC machining.
ʻO ka hua'ōlelo hope
He ʻenehana hou loa ka paʻi 3D, a ua hoʻomaka wale kāna kaua no ka hoʻokele ʻana i ka mākeke. ʻAe, aia nā mīkini paʻi 3D pipiʻi a me nā mea hou i hōʻemi i ke āpau i ka mea hiki i ka mīkini CNC, akā mai ka manaʻo o ka prototyping, ʻaʻole hiki ke noʻonoʻo ʻia ma aneʻi. ʻAʻohe hoʻokahi-nui kūpono i nā hoʻonā āpau. ʻO ke koho ʻana i kekahi ma luna o nā mea ʻē aʻe e pili ana i nā kikoʻī hoʻolālā o kāu papahana prototyping.
