ʻO ka mea mua e kamaʻilio e pili ana i ke ʻano kino o ka hana ʻana o ka titanium alloy.ʻOiai ʻoi aku ka kiʻekiʻe o ka ʻokiʻoki o ka titanium alloy ma mua o ke kila me ka paʻakikī like, ʻoi aku ka paʻakikī o ke ʻano kino o ka hoʻoili ʻana i ka titanium alloy ma mua o ka hoʻoili ʻana i ke kila, kahi e hoʻonui ai i ka paʻakikī o ka hana ʻana i ka titanium alloy.
He haʻahaʻa loa ka conductivity thermal o ka hapa nui o nā alloys titanium, ʻo 1/7 wale nō o ke kila a me 1/16 o ka alumini.No laila, ʻaʻole e hoʻoneʻe koke ʻia ka wela i hana ʻia i ka ʻoki ʻana i nā alloys titanium i ka mea hana a i ʻole e lawe ʻia e nā ʻāpana, akā e hōʻiliʻili ʻia i loko o ka ʻoki ʻana, a hiki ke kiʻekiʻe ka wela i 1 000 °C a ʻoi aku paha. , ʻo ia ka mea e hoʻopau koke ai ka ʻoki ʻoki o ka mea hana, ʻāʻī a pohā.ʻO ke kūkulu ʻia ʻana o ka lihi i kūkulu ʻia, ʻo ke ʻano wikiwiki o kahi ʻaoʻao i hoʻopau ʻia, e hoʻonui i ka wela i ka ʻoki ʻana, e hoʻopōkole ana i ke ola o ka mea hana.
ʻO ka wela kiʻekiʻe i hana ʻia i ka wā o ke kaʻina hana e hoʻopau ai i ka pono o ka ʻili o nā ʻāpana titanium alloy, ka hopena i ka emi ʻana o ka pololei geometric o nā ʻāpana a me kahi ʻano hana paʻakikī e hōʻemi nui i ko lākou ikaika luhi.
Hiki ke kōkua ka elasticity o nā alloys titanium i ka hana o nā ʻāpana, akā i ka wā o ka ʻoki ʻana, ʻo ka deformation elastic o ka mea hana he kumu nui o ka haʻalulu.ʻO ke kaomi ʻoki ʻana e neʻe aku ka mea hana "elastic" mai ka mea paahana a paʻa i ʻoi aku ka nui o ka paio ma waena o ka mea hana a me ka mea hana ma mua o ka hana ʻoki.ʻO ke kaʻina hana friction e hoʻoulu i ka wela, e hoʻonui ana i ka pilikia o ka conductivity thermal maikaʻi ʻole o nā alloys titanium.
ʻOi aku ka koʻikoʻi o kēia pilikia i ka wā e hoʻomaʻamaʻa ai i nā ʻāpana ʻāpana lahilahi a i ʻole ke apo i hiki ke hoʻololi ʻia.ʻAʻole ia he hana maʻalahi ka hana ʻana i nā ʻāpana ʻāpana lahilahi me ka titanium alloy e like me ka pololei o ke ana i manaʻo ʻia.No ka mea, i ka wā e hoʻokuʻu ʻia ai ka mea hana e ka mea hana, ua ʻoi aku ka deformation kūloko o ka pā lahilahi ma mua o ka elastic range a me ka deformation plastic, a piʻi nui ka ikaika a me ka paʻakikī o ka ʻokiʻoki.I kēia manawa, ʻoi aku ka kiʻekiʻe o ka mīkini ma ka wikiwiki o ka ʻoki ʻana i hoʻoholo ʻia ma mua, a ʻoi aku ka hopena o ka ʻaʻahu ʻana i nā mea hana ʻoi.Hiki ke ʻōlelo ʻia ʻo ka "wela" ka "kumu kumu" e paʻakikī ai ka hana ʻana i nā alloys titanium.
Ma ke ʻano he alakaʻi i ka ʻoihana ʻokiʻoki, ua hōʻuluʻulu maikaʻi ʻo Sandvik Coromant i kahi kaʻina hana no ka hana ʻana i nā alloys titanium a kaʻana like me ka ʻoihana holoʻokoʻa.Ua ʻōlelo ʻo Sandvik Coromant ma ke kumu o ka hoʻomaopopo ʻana i ke ʻano hana o nā alloys titanium a me ka hoʻohui ʻana i ka ʻike i hala, ʻo ka ʻike kumu nui no ka hana ʻana i nā alloys titanium penei:
(1) Hoʻohana ʻia nā mea hoʻokomo me ka geometry maikaʻi e hōʻemi i ka ikaika ʻoki, ʻoki i ka wela a me ka deformation mea hana.
(2) E mālama i ka hānai mau e pale aku i ka paʻakikī o ka mea hana, pono ka mea hana i ke kūlana hānai i ka wā o ka ʻoki ʻana, a ʻo ka nui o ka ʻoki radial ae he 30% o ka radius i ka wā wili.
(3) Hoʻohana ʻia ka wai ʻoki kiʻekiʻe a me ke kahe nui e hōʻoia i ka paʻa ʻana o ka wela o ke kaʻina hana mīkini a pale i ka degeneration ʻili o ka mea hana a me ka pōʻino o ka mea hana ma muli o ka wela nui.
(4) E hoʻopaʻa i ka ʻaoʻao o ka ʻaoʻao ʻoi, ʻo nā mea hana blunt ke kumu o ke kūkulu ʻana a me ka ʻaʻahu ʻana o ka wela, hiki ke maʻalahi i ka hemahema o ka mea hana.
(5) ʻO ka mīkini i loko o ke kūlana palupalu o ka titanium alloy e like me ka hiki, no ka mea, lilo ka mea i mea paʻakikī i ka mīkini ma hope o ka paʻakikī, a hoʻonui ka mālama wela i ka ikaika o ka mea a hoʻonui i ka lole o ka mea hoʻokomo.
(6) E hoʻohana i ka radius ihu nui a i ʻole chamfer e ʻoki i loko, a e hoʻokomo i nā kihi ʻoki he nui i loko o ka ʻoki.Hoʻemi kēia i ka ikaika ʻoki a me ka wela i kēlā me kēia wahi a pale i ka haki kūloko.I ka wili ʻana i nā alloys titanium, ma waena o nā ʻāpana ʻoki, ʻoi aku ka mana o ka wikiwiki o ka ʻoki ʻana i ke ola mea hana vc, a ukali ʻia e ka nui o ka ʻoki radial (hohonu milling) ae.
