Nā Laulā niho niho māhoe

ʻO ka hoʻomohala hou ʻana o ka ʻenehana ʻoki ʻoki ʻia he pahi me kahi ʻano geometrical kūikawā (ʻelua niho me nā contours like ʻole). ʻO kēia hui ʻana e hiki ai i ka helu o nā paʻi ke hana i kahi kaula piha e hoʻemi ʻia 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 ia, akā ʻo ka paʻi kiʻekiʻe Tap TT (twin-toothed blade) e lanakila ai i kahi pilikia e pili ana i kahi hāmeʻa kuʻuna multi-toothed, ʻo ia hoʻi, kahi haʻalulu i hana ʻia e ka ikaika ʻoki nui. Ke hoʻohālikelike ʻia me ka maka maʻamau, ʻoi aku ka pōkole o ka ʻoki ʻana o TT Blade, kahi e hōʻemi ai i ka ikaika ʻoki a hōʻemi 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 mea maikaʻi ʻē aʻe, ʻo ia ka wili ʻia o nā lau TT i nā blank 16 maʻamau, a ʻo nā lau niho niho ʻē aʻe e koi 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 pau 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 kahi ʻaoʻao kū pololei ma mua o ka niho lua o ka ʻaoʻao hoʻopau pae. Hoʻopau ka TT Blade i ʻelua ʻoki like ʻole 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 hou, ua wehe ʻia kēlā me kēia niho me ka mea i ʻōlelo ʻia no ka mālama ʻana i ke koena ikaika i hāʻawi ʻia i ka pā pahi. ʻAʻole kēia e ʻōlelo ʻo ke ʻano ʻokiʻoki hou i ka lōʻihi e hiki ai ke hana ʻia i kahi kaula holoʻokoʻa, ʻoki wale ia i kahi hapa liʻiliʻi o ka leo e like me ka like, ʻo ka lau ma o kekahi mau paʻi e hoʻopau i ka hānai radial.
