Ke ʻimi nei i kahi ka mīkini pololei kokoke iaʻu hale hana e hāʻawi i nā ʻāpana koʻikoʻi-ʻaʻole wale i ka hoʻomanawanui, akā hilinaʻi? ʻAʻole ʻoe e ʻimi nei i "kekahi" hale kūʻai. Pono ʻoe i ka mea nāna e mālama i nā nozzles hoʻohuihui cobalt AMS 5387 me ka ʻole o ka ʻōpala, paʻa i ka ± 0.005 mm ma nā hale pahu pahu piston pump ma lalo o ke kaʻa kaʻa wela, a e ʻimi i kēlā me kēia pūʻulu o nā mea T800 i kona helu wela. ʻAʻole kēlā hana maʻamau. Ua loaʻa.
I ka manawa "kokoke iaʻu" ʻo ia ka "ʻike i kāu noi"
Paʻi pinepine ʻia ʻo "Machining precision ma kahi kokoke iaʻu hale hana" me ka wikiwiki - ma hope o ka hala ʻana o ka mea hoʻolako i ka hāʻawi ʻana, hōʻole i kahi kāhea GD&T, a i ʻole e hoʻouna i kahi hale pahu kaomi me nā micro-cracks i ʻike ʻole ʻia e ka maka ʻōlohelohe akā pōʻino ma lalo o 350 bar. Ua ʻike mākou: he OEM hydraulic ʻAmelika ʻAmelika e hana hou ana i ka 12% o nā hoʻoheheʻe e komo mai ana no ka mea ʻaʻohe o kā lākou hale kūʻai kūloko i ka mana o ka hoʻolei ʻana i ke one. Ua ʻoki ʻia kekahi mea kūʻai aku i ʻekolu holo prototype o nā huila winch center shaft—he $2,400 ke kumu kūʻai o kēlā me kēia—no ka mea ʻaʻole i hoʻāʻo ʻia ka paʻakai paʻakai. ʻAʻole kēia nā hewa hana. ʻO lākou nā ʻōnaehana ʻōnaehana: ʻaʻohe mea hiki ke ʻike ʻia, ʻaʻohe hōʻoia ʻana i ka wela, ʻaʻohe CMM-hōʻoia GD&T alignment ma waena o ka casting datum a me nā hiʻohiʻona mīkini hope loa.
ʻO ia ke kumu ʻaʻole hoʻonā ka pili wale i ka hilinaʻi. ʻO ka mea nui * ka pili ʻana o ke kaʻina hana: ka hoʻolei ʻana, ka mālama ʻana i ka wela, ka CNC multi-axis, a me ka metrology ma lalo o hoʻokahi hale hoʻokō ISO-me nā mea ʻenekinia i hoʻohuli hou i nā ʻohana 17 AMS 5387 pauma. ʻAʻole ʻike theoretical. ʻO ka mākaukau i hōʻoia ʻia i ka ʻāina i ka huli ʻana, ka wili ʻana, a me ka wili ʻana i nā alloy cobalt-nickel kahi e hāʻule ai ke ola o ka mea hana i ka 60% inā e hoʻololi ʻia ka neʻe ʻana o ka coolant ma 0.3%.
ʻEhā mau mana e pale ai i ka hāʻule
ʻO ka hapa nui o nā hale kūʻai e papa inoa i ka "CNC machining" a me ka "casting." Hoʻopili liʻiliʻi iā lākou i mea e hōʻoiaʻiʻo ai i ke kūpaʻa dimensional ma waena o nā pōʻai wela. Eia ka mea e hoʻoneʻe ai i ka nila:
- Hoʻohui kū pololei mai ka heheʻe a hiki i ka pau ʻana: Ua ninini ʻia ka hao a me ke kila kuhili ʻole i loko o ka hale, a laila hana ʻia ma mua o ka hoʻomaha ʻana i ke kaumaha—no laila e paʻa pono nā ʻāpana hope ma hope o ka ʻelemakule. ʻAʻohe lima lima. ʻAʻohe helu i nalowale.
- ʻO ka hana kūikawā Cobalt-alloy-ʻaʻole wale ka hiki: Mea hana hoʻolaʻa, nā laina hoʻoluʻu cryogenic, a me ka hoʻoheheʻe ʻana o ka spindle no AMS 5387 a me T800. ʻAʻole mākou "hoʻāʻo" i kēia mau mea. Hoʻopaʻa mākou i ka lole carbide no kēlā me kēia ʻīniha kubiki i wehe ʻia-a hoʻoponopono i ka helu hānai i ka manawa maoli me ka hoʻohana ʻana i nā mea ʻike ikaika i ka hana.
- Nānā ma ke ʻano he hoa hoʻolālā: Hoʻomaka kēlā me kēia pahu kaomi me ke kaha kiʻi ʻana—ʻaʻole wale "hiki iā mākou ke hana?" akā "e ola anei kēia geometry i 10,000 mau puʻupuʻu kaomi me ka ʻole o ka haʻalulu ʻana i ka interface noho?" Loaʻa i kā mākou hōʻike CMM ka nānā ʻana o GD&T stack-up, ʻaʻole wale i ka hala ʻana a i ʻole nā hae.
- ʻO ka hoʻopaʻi waiwai, ʻaʻole wale ka palapala hōʻoia: ʻAʻole "hōʻoia i ka ASTM A494." Ke hōʻoia nei mākou i ka nui o ka palaoa, ka māhele ʻana o ka māhele intermetallic, a me ka like ʻole o ka paʻakikī ma waena o nā ʻāpana-no ka mea, ʻaʻole e hopu ʻia ka hoʻāʻo ʻana o Brinell 3-point ma ka ʻili i ka hoʻokaʻawale ʻana i lalo i loko o kahi kahua pahū 120-mm-mānoanoa.
No ke aha e hoʻomaka ai ka "Hōʻoiaʻiʻo" ma mua o ka ʻoki mua ʻana
Hoʻohiki kekahi mau mea kūʻai aku i nā huaʻōlelo wikiwiki. Hoʻouna mākou i nā manaʻo manaʻo ʻenehana i loko o 48 mau hola-me nā memo hana hana e like me: "E ʻoki ʻia kēia radius 0.12-mm ma ka ʻaoʻao o ka pahu valve i ka wā honing. Manaʻo i ka liʻiliʻi 0.25-mm, a i ʻole e hoʻololi i ka electrochemical deburring." ʻAʻole kēlā hoʻihoʻi. ʻO ia ka hoʻēmi pilikia e loaʻa iā ʻoe mai kahi hui kūloko.
Ua hoʻouna mākou ma luna o 8,200 mau ʻāpana maʻamau i nā mea kūʻai aku ma Kelemānia, Kanada, a me Singapore - me ka hiki ke ʻike piha ʻia, nā moʻolelo mālama wela, a me nā hōʻike nānā ʻatikala mua i hoʻopaʻa ʻia e nā labs ʻaoʻao ʻekolu. ʻAʻohe ʻokoʻa. I ka wā e pono ai ka mea hoʻoheheʻe ʻia ma ʻAsia Hikina Hema i 47 mau puʻupuʻu kobalt maʻamau maʻamau i nā lā 11, ua hoʻohuli hou mākou i kahi slot umu hoʻomaʻamaʻa wela, holo i ka metrology hoʻololi pō, a hāʻawi ʻia me ka ʻikepili CMM hōʻoia e hōʻike ana i nā anawaena koʻikoʻi āpau i loko o ± 0.003 mm. ʻAʻole "kokoke iaʻu." Ma kahi kokoke i kāu lā palena. Ma kahi kokoke i kāu spec. Ma kahi kokoke i kāu ʻano hemahema.
Nā ʻanuʻu aʻe: He aha e nīnau ai i kāu hoa hana mīkini pololei aʻe
Mai nīnau "Ke hana nei ʻoe i CNC?" Nīnau:
- "E hōʻike mai iaʻu i kāu mau hōʻike CMM ʻekolu hope loa no nā ʻāpana kobalt-alloy - ʻo ia hoʻi pehea ʻoe i hōʻoia ai i ke kūlana ʻoiaʻiʻo o nā hiʻohiʻona pili e pili ana i ka hoʻolei ʻana i nā datums."
- "Pehea ʻoe e hōʻoiaʻiʻo ai i ka paʻa wela o kāu hoʻoheheʻe ʻia? Ke hoʻopaʻa nei ʻoe i ka mahana o ka poni i kēlā me kēia ninini, a i ʻole ke hilinaʻi nei i ka nānā ʻana?"
- "He aha kāu awelika hoʻololi mea hana i ka wā e hana ai i ka AMS 5387 ma 45 m / min? A pehea ʻoe e uku ai i ka ʻaʻahu ʻana ma ka hohonu Z-axis?"
Inā maopopo ʻole nā pane - a ʻoi aku ka maikaʻi, maʻamau - ke kamaʻilio nei ʻoe i kahi mea kūʻai aku, ʻaʻole he hoa. ʻAʻole pili ka mīkini kikoʻī hilinaʻi i kahi. E pili ana i ka mana palapala, ka hoʻokolokolo metallurgical i hōʻoia ʻia, a me ka makemake e ʻōlelo "ʻaʻole" i kahi kiʻi e hāʻule i ka lawelawe.
No ka poʻe ʻenekinia e hōʻike ana i nā kiwi puʻupuʻu, nā hale cylinder, a i ʻole nā ʻāpana winch lole kiʻekiʻe: e hoʻomaka me ka loiloi ʻenehana-ʻaʻole kahi noi ʻōlelo. No ka mea maikaʻi loa ka mīkini pololei kokoke iaʻu hale hana ʻaʻole ʻike ʻia ma ka palapala ʻāina. Ua hōʻoia ʻia ma ka ʻikepili.
