Ma muli o ka paʻakikī ikaika o ka mea i hui pū ʻia me ke kila manganese kiʻekiʻe a me ke kila hui, hiki ke hoʻopaʻa ʻia kahi hui hao kūpaʻa me ka paʻakikī ikaika ma luna o ka ʻili, i hoʻomaikaʻi nui ʻia ai ka ikaika o ka ʻili o ka niho bākeke, i mea e loaʻa ai ka niho bākeke kūpono. Ma muli o kona mau loina ikaika i ke kaʻina hana o ke kūpaʻa maloʻo, pono e koho ʻia nā hui hao me ka paʻakikī kiʻekiʻe a me ke kūpaʻa maikaʻi i loko o ka mea.
Wahi a nā haʻawina pili, ʻoi aku ka ikaika o ke kūpaʻa ʻana o ka hao kiʻekiʻe ma mua o ke kila manganese kiʻekiʻe, a hoʻohana ʻia ke kila hao kiʻekiʻe a i ʻole ke kila hao martensitic i ka hana ʻana i nā niho bākeke hou a me ka hoʻoponopono ʻana i nā niho bākeke kahiko. I ka hoʻoponopono ʻana i ka mālama ʻana, hiki ke ʻoki ʻia ka lapalapa acetylene ma ka piko o ka niho bākeke kahiko, e waiho ana i kahi ʻauwaha, a laila e hoʻohana i ke koʻokoʻo wili hao manganese austenitic e hana i ka mālama kūpono o ke ʻano mua, a ʻo ka hope loa e uhi i ka mālama wili ma luna o ka ʻili e hoʻomaikaʻi i ke kūpaʻa ʻana o nā mea ʻeli nui i loko o nā mines.

ʻO ka mea mua, ka ʻōnaehana ʻoki
Ke pane ka niho bākeke me ka pōhaku (ore) ma lalo o ke kaumaha hopena kiʻekiʻe, ma ka ʻaoʻao hoʻokahi, pili ia me ka ʻili pōhaku (ore) a hana i kahi ikaika hopena nui, inā haʻahaʻa ka ikaika hua o ka mea niho bākeke, hana ka piko o ka niho bākeke i kahi deformation plastic, kahi maʻalahi ke hana i kahi ʻauwaha plastik. Ma ka ʻaoʻao ʻē aʻe, i ka wā e hoʻokomo ʻia ai ka niho bākeke i loko o ka pōhaku (ore), inā haʻahaʻa ka paʻakikī o ka niho bākeke ma mua o ka paʻakikī o ka pōhaku (ore), hoʻokuke ʻia nā ʻāpana pōhaku (ore) i loko o ka ʻili o ka niho bākeke, kahi e hana ai i nā ʻāpana lōʻihi i ke ʻano o kahi piʻo a i ʻole spiral, e hana ana i kahi groove ʻoki, hiki ke hele pū me nā ʻāpana ʻoki liʻiliʻi. Ma muli o ka hana ʻokiʻoki a me ka nui o ka deformation, hana ka nui o ka deformation latent heat, ʻike ʻia nā ʻanuʻu paheʻe kokoke a hoʻonohonoho pono ʻia, ka hoʻokumu ʻana o nā wrinkles, a me kona friction me ka pōhaku (ore) e hana i ka wela friction, ka deformation latent heat a me ka friction heat i hui pū ʻia e hoʻonui i ka mahana o ka chip, recrystallization dynamic, tempering softening, dynamic phase change, etc., hoʻololi i ke ʻano o loko o ka chip, a ʻike ʻia kekahi hanana hoʻoheheʻe kūloko.
ʻO ka lua, ka ʻōnaehana ʻili luhi
Hoʻokomo ʻia ka niho bākeke i loko o ka pōhaku (ʻonika) e hoʻihoʻi, a ʻo ka ʻauwaha palau plastik i hana ʻia ma luna o ka ʻili e kuʻi ʻia e nā ʻāpana pōhaku ma ka hāpai ʻana no nā manawa he nui, hiki ke hana i kahi papa metala multi-flow, a e hana ʻia nā māwae a me nā māwae palupalu ke ʻoi aku ke kaumaha o ka mea niho bākeke ma mua o ka palena ikaika. ʻO ka mua e haki kū pololei i ke kuhikuhi ʻaʻahu, a ʻo kekahi e haki a haehae ʻia paha i ke kuhikuhi ʻaʻahu, me nā kaha ʻōwili laumania ma ka ʻaoʻao mua, pālahalaha ma ke kua, a me nā kaha overlapping i hana ʻia e ka deformation kuʻi ʻana ma nā ʻaoʻao. Inā he angular ka pōhaku, e ʻokiʻoki ia i ka papa deformation a hana i nā ʻōpala, he pālahalaha a me ka flake me nā ʻaoʻao ʻino. Aia kekahi kūlana, i ka wā e hana pinepine ai ka niho bākeke a me ka pōhaku, e hoʻololi ka deformation plastic niho bākeke a hana i ka hopena paʻakikī kiʻekiʻe, i mea e palupalu ai ka ʻili niho o ka niho bākeke, ma lalo o ka hopena ikaika o ka pōhaku, e hana ka ʻili niho i nā ʻāpana palupalu, a he mau māwae radial o nā hohonu like ʻole kona ʻili. ʻO kēia ʻano haki palupalu he ʻano hana luhi hoʻi ia. Pili ka ʻano hana hāʻule ʻana i ka mea a me nā kūlana hana, ʻo ia hoʻi ka ʻoki ʻana, ka ʻili ʻana i ka luhi a me nā ʻano hana ʻē aʻe. Ma ke ʻano laulā, ʻo ka ʻano hana ʻoki e hoʻomalu i ke kaʻina hana hāʻule ʻana o nā niho bākeke, e hōʻea ana ma mua o 7O; Me ka hoʻonui ʻana o ka paʻakikī o nā niho bākeke, ua hoʻonui mālie ʻia ka ʻano hana ʻili luhi, e helu ana no 2O ~ 3O; Ke hiki ka paʻakikī o ka mea i ka palena kiʻekiʻe, hoʻonui ʻia ka brittleness a hiki ke hana ʻia ka chipping brittle. No nā kūlana hana i hoʻomalu ʻia e ka ʻano hana ʻoki, ʻo ka hoʻomaikaʻi ʻana i ka paʻakikī o ka mea niho bākeke e kōkua i ka hoʻomaikaʻi ʻana i kona kūpaʻa ʻana i ka ʻaʻahu; No ka ʻano hana ʻili luhi, pono ka mea e loaʻa kahi paʻakikī a paʻakikī maikaʻi;Paʻakikī kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka haki ʻana, ka wikiwiki o ka ulu ʻana o nā māwae haʻahaʻa a me ke kūpaʻa kiʻekiʻe i ka luhi i ka hopena e kōkua ana i ka hoʻomaikaʻi ʻana i ke kūpaʻa ʻana o nā mea.
