ʻO kekahi mau'āpana ākea o ka hopena-a me nā mea hana i loko o nā mea hana e noho ai, e like me ke kikowaena kikowaena-center-cute-cute a me ka hoʻonohonohoʻana ma o ka lehulehu o nā flutes; e Helix Angle; ma ka mea; a me nā mea hoʻohālike. Hiki ke hoʻokaʻawaleʻia kēlā me kēia māhele i ka noi kiko'ī a me nā geometry kūikawā.
ʻO kahi kihi helix kaulana loa,ʻoi loa no kaʻokiʻana i nā mea hao,ʻo ia ka 30 °. No ka hoʻopauʻanapau nā miles, he mea maʻamau keʻike i ka spiral paʻa hou, me helix kihi 45 ° a 60 °.Hoʻopau pololei i nā mille(Helix Angle 0 °) i hoʻohanaʻia ma nā noi kūikawā, e like me nā pohō a iʻole nā hui o ka epoxy a me ke aniani. Ua hoʻohana pūʻia nā milna hope loa i nā Milna ma mua o kaʻokiʻana ma mua o ka hanaʻana i ka carl carl e ka carl end a. bergstrom o Weldon Company hui ma 1918.
Aia i nā milina i pau me nāʻano helix helix a iʻole nā helix he helix he nui a me ka hōʻemiʻana i nā mea e haʻalele ana ʻO kekahi mau hoʻolālā hou e komo pū me nā hiʻohiʻona liʻiliʻi e like me ka chamfer choffer a chipbreaker. ʻOiaiʻoi aku ka nui o ke kumukūʻai nui, ma muli o ke hoʻolālāʻoi aku ka paʻakikī a me ka hana hana, e like me kēlāpau nā mileshiki ke lōʻihi ma muli o ka emiʻana o ka lole a hoʻomaikaʻi i nā huahana i lokoKe kahua wikiwiki loa(HSM) noi.
Ke lilo nei ia i mea maʻamau no ka hoʻohanaʻana i nā milina paʻa e hoʻololiʻia e nā kumukūʻai hou aʻe e hoʻokomoʻiaʻokiʻana i nā hana hana(ʻo ia,ʻoi aku ka nui o ka mea kūʻai aku, e hōʻemi i nā manawa hana-hoʻololi a waiho i nā kihi maʻalahi a iʻole kaʻokiʻana i nā kihi o ka lole).
E kūʻai aku nā milla ma keʻano like me keʻano like me ka midric shank a me nāʻokiʻana i nāʻupena. Ma ko Hawaii, loaʻa koke ana metric ke loaʻa, akā ua hoʻohana waleʻia ma kekahi mau mīkini mīkiniʻaʻole i nā mīkini a me nā poʻe'ē; Ma C Kanada, ma muli o ka loaʻaʻana o ka'āina o mākou i ka US,ʻo ia nō ka mea he nui.
