Nā Laulā niho niho māhoe
ʻO ka hoʻomohala hou ʻana o ka ʻenehana ʻoki kaula he pahi me kahi ʻano geometrical kūikawā (ʻelua niho me nā contours like ʻole). Hiki i kēia hui ke hoʻemi i ka helu o nā paʻi e hana i kahi kaula piha e like me ka 40% i hoʻohālikelike ʻia me kahi mea hana niho hoʻokahi, ʻoiai e hoʻonui ana i ke ola mea hana.
ʻOiai ma ke ʻano ʻenehana he pahi niho-nui, akā, ʻo ka paʻi kiʻekiʻe Tap TT (twin-toothed blade) e lanakila ai i kahi pilikia e pili ana i kahi hāmeʻa multi-toothed kuʻuna, ʻo ia hoʻi, kahi haʻalulu i hoʻokumu ʻia e ka ikaika ʻoki nui. Ke hoʻohālikelike ʻia me ka maka maʻamau, ʻoi aku ka pōkole o ka ʻoki ʻana o ka TT Blade, kahi e hōʻemi ai i ka ikaika ʻoki a hoʻemi i ka hopena o ka flutter. A ma muli o ka pōkole pōkole (t ka nui) o ke ʻano niho i ka lihi o ka lau TT, hiki ke hana ʻia ke kaula kokoke i ka ʻanuʻu.
ʻO kekahi pōmaikaʻi ʻē aʻe, ʻo ia ka wili ʻia o nā lau TT i nā blank 16 maʻamau, a ʻo nā ʻaoʻao niho niho ʻē aʻe e koi aku i nā blanks nui aʻe. ʻO ke kī i ka ʻoki ʻana i ka maikaʻi o nā lau TT he hoʻolālā "niho roughing/Finish tooth shape", kahi i ʻoi aku ka pōkole o nā niho ʻōpala ma mua o ka hoʻopau ʻana. No laila, ʻoi aku ka hohonu o ke kaula alakaʻi ma mua o ke kaula lua.
I kekahi hihia, ua like kēia mau niho i ke ʻano o ke ʻano o ka ʻaoʻao niho mīkini. Hōʻike ka ʻaoʻao o ka niho mua o ka mea hana Cheijin i ka ʻaoʻao alakaʻi kū pololei ma mua o ka niho lua o ka ʻaoʻao hoʻopau milo. Hoʻopau ka TT Blade i ʻelua ʻoki ʻokoʻa ma mua o ka hoʻopau ʻana i ʻelua ʻoki like ʻole ma nā hohonu like ʻole. Hoʻoponopono ʻia kēlā me kēia niho no ka maikaʻi, a ʻoiaʻiʻo, ua hui pū kēlā me kēia niho i kekahi i kekahi e hana i kahi ʻano niho piha i ka hikiwawe.
Eia kekahi, wehe ʻia kēlā me kēia niho i kahi mea like me ka mea i ʻōlelo ʻia e mālama i ke koena ikaika i hāʻawi ʻia i ka pahi pahi. ʻAʻole kēia no ka ʻōlelo ʻana i ke ʻano o ka ʻoki ʻoki hou e like me ka lōʻihi o ka hahau ʻana i kahi kaula holoʻokoʻa, ʻoki wale ia i kahi hapa liʻiliʻi o ka leo e like me ke ʻano like, ʻo ka ʻili ma kekahi mau paʻi e hoʻopau i ka hānai radial.
