ʻO ka mīkini CNC kahi huaʻōlelo maʻamau i hoʻohana ʻia i ka hana ʻana a me nā noi ʻoihana. Akā he aha ka CNC? A he aha ka mīkini CNC?

CNC 101: ʻO ka huaʻōlelo CNC ʻo ia ka 'kaomi helu kamepiula', a ʻo ka wehewehe ʻana i ka mīkini CNC ʻo ia ke kaʻina hana subtractive e hoʻohana maʻamau i nā mana kamepiula a me nā mea mīkini e wehe i nā papa o nā mea mai kahi ʻāpana waiwai—i ʻike ʻia ʻo ka blank a i ʻole. mea hana—a hana i kekahi mahele i hana ma'amau. He kūpono kēia kaʻina hana no ka nui o nā mea, e like me nā metala, plastics, lāʻau, aniani, foam, a me nā composites, a loaʻa ka noi ma nā ʻano ʻoihana like ʻole, e like me ka mīkini CNC nui, ka mīkini o nā ʻāpana a me nā prototypes no ke kelepona, a me CNC. ʻO nā ʻāpana aerospace machining, e koi ana i ka hoʻomanawanui ʻoi aku ka paʻakikī ma mua o nā ʻoihana ʻē aʻe. E hoʻomaopopo he ʻokoʻa ma waena o ka wehewehe ʻana i ka mīkini CNC a me ka wehewehe ʻana o ka mīkini CNC-he hana kekahi a he mīkini kekahi. ʻO ka mīkini CNC (i kapa hewa ʻia i kekahi manawa he mīkini C a me C) he mīkini programmable i hiki ke hoʻokō pono i nā hana o ka mīkini CNC.

ʻO ka mīkini CNC ma ke ʻano he hana hana a me ka lawelawe i loaʻa i ka honua holoʻokoʻa. Hiki iā ʻoe ke ʻimi maʻalahi i nā lawelawe mīkini CNC ma ʻEulopa, a me Asia, ʻAmelika ʻĀkau, a me nā wahi ʻē aʻe a puni ka honua.

Hōʻike pinepine ʻia nā kaʻina hana subtractive, e like me CNC machining, e like me nā kaʻina hana additive, e like me ka paʻi 3D, a i ʻole nā ​​​​kaʻina hana formative, e like me ka hoʻoheheʻe wai. ʻOiai ʻo nā kaʻina hana subtractive e hoʻoneʻe i nā papa o nā mea mai ka mea hana e hana i nā ʻano a me nā hoʻolālā maʻamau, ʻo nā kaʻina hana hoʻohui e hōʻuluʻulu i nā papa o nā mea e hana ai i ke ʻano i makemake ʻia a me nā kaʻina formative deform a hoʻololi i nā mea waiwai i ke ʻano i makemake ʻia. ʻO keʻano automate o ka CNC machining e hiki ai ke hana i ke kiʻekiʻe kiʻekiʻe a me ka pololei kiʻekiʻe, nā'āpana maʻalahi a me ka maikaʻi o ke kumukūʻai i ka wā e hoʻokō ai i ka holo hoʻokahi a me ka medium-volume. Eia nō naʻe, ʻoiai ke hōʻike nei ka mīkini CNC i kekahi mau mea maikaʻi ma mua o nā kaʻina hana ʻē aʻe, ʻo ke kiʻekiʻe o ka paʻakikī a me ka paʻakikī e hiki ke loaʻa no ka hoʻolālā ʻāpana a me ke kumu kūʻai o ka hana ʻana i nā ʻāpana paʻakikī.

ʻOiai ʻo kēlā me kēia ʻano kaʻina hana i loaʻa nā pono a me nā hemahema, e pili ana kēia ʻatikala i ke kaʻina hana CNC, e wehewehe ana i nā kumu o ka hana, a me nā ʻāpana like ʻole a me nā mea hana o ka mīkini CNC. Eia hou, ke ʻimi nei kēia ʻatikala i nā hana mīkini CNC machining a hāʻawi i nā mea ʻē aʻe i ke kaʻina hana mīkini CNC.

Ma ka nana aku, e uhi keia alakai:

Aia ʻoe ma waena o nā hana i kēia manawa a i ʻole kahi mea hana e ʻimi nei e hoʻolimalima? Ua uhi mākou iā ʻoe me kā mākou hōʻiliʻili hohonu o nā kumuwaiwai no ka poʻe ʻimi hana ʻoihana a me nā mea hana e ʻimi nei e hoʻopiha i nā kuleana. Inā loaʻa iā ʻoe kahi kūlana hāmama, hiki iā ʻoe ke hoʻopiha i kā mākou palapala no kahi manawa e hōʻike ʻia ma ka nūhou Thomas Monthly Update.

Ke hoʻololi nei mai ke kaʻina hana mīkini helu (NC) i hoʻohana i nā kāleka lipine punched, ʻo ka mīkini CNC he kaʻina hana e hoʻohana ana i nā mana kamepiula e hana a hoʻopololei i ka mīkini a me nā mea ʻokiʻoki e hana i nā mea waiwai-e laʻa, metala, plastic, lāʻau, ʻūhā, composite. , etc.-i loko o nā ʻāpana maʻamau a me nā hoʻolālā. ʻOiai ke hāʻawi nei ke kaʻina hana machining CNC i nā mana like ʻole a me nā hana, ʻo nā loina kumu o ke kaʻina hana e hoʻomau i ka like ma o lākou āpau. ʻO ke kaʻina hana mīkini CNC maʻamau e pili ana i nā pae aʻe:

Hoʻomaka ke kaʻina hana machining CNC me ka hana ʻana i kahi vector 2D a i ʻole 3D solid part CAD design ma ka hale a i ʻole e kahi hui lawelawe hoʻolālā CAD/CAM. ʻO ka polokalamu kamepiula-aided design (CAD) hiki i nā mea hoʻolālā a me nā mea hana ke hana i kahi kumu hoʻohālike a i ʻole ka hoʻohālikelike ʻana i kā lākou ʻāpana a me nā huahana me nā kikoʻī ʻenehana kūpono, e like me nā ana a me nā geometries, no ka hana ʻana i ka ʻāpana a huahana paha.

Hoʻopaʻa ʻia nā hoʻolālā no nā ʻāpana mīkini CNC e nā mea hiki (a i ʻole hiki ʻole) o ka mīkini CNC a me nā mea hana. No ka laʻana, he cylindrical ka hapa nui o ka mīkini mīkini CNC no laila ua kaupalena ʻia nā ʻāpana geometries ma o ke kaʻina hana CNC machining e like me ka hana ʻana o ka mea hana i nā ʻāpana kihi curved. Eia kekahi, ʻo nā waiwai o ka mea i mīkini ʻia, ka hoʻolālā ʻana i nā mea hana, a me nā mea hana hana o ka mīkini e hoʻopaʻa hou i nā hiki ke hoʻolālā, e like me ka mānoanoa hapa liʻiliʻi, ka nui o ka hapa nui, a me ka hoʻopili ʻana a me ka paʻakikī o nā lua o loko a me nā hiʻohiʻona.

Ke hoʻopau ʻia ka hoʻolālā CAD, e hoʻokuʻu aku ka mea hoʻolālā iā ia i kahi ʻano faila kūpono CNC, e like me STEP a i ʻole IGES.
