'Oka 'ilikai (machining term)

ʻO ke ʻano ʻino o ka ʻili e pili ana i ka like ʻole o ka ʻili i hoʻoponopono ʻia me ka hakahaka liʻiliʻi a me nā piko liʻiliʻi a me nā awāwa. ʻO ka mamao (ka lōʻihi o ka nalu) ma waena o nā piko nalu ʻelua a i ʻole ʻelua ʻauʻau nalu he liʻiliʻi loa (emi ma lalo o 1mm), ʻo ia ka microscopic geometric error. ʻO ka liʻiliʻi o ka ʻili o ka ʻili, ʻoi aku ka maʻalahi o ka ʻili. ʻO ka maʻamau, ʻike ʻia nā hiʻohiʻona morphological me ka mamao o ka nalu ma lalo o 1 mm i ka ʻinoʻino o ka ʻili, ua wehewehe ʻia nā hiʻohiʻona morphological me ka nui o 1 a 10 mm ʻo ka hawewe o ka ʻili, a ʻo nā hiʻohiʻona morphological me ka nui i ʻoi aku ma mua o 10 mm ua wehewehe ʻia he topography.
Hoʻokumu pinepine ʻia ka ʻili o ka ʻili e ke ʻano hana i hoʻohana ʻia a me nā kumu ʻē aʻe, e like me ka friction ma waena o ka mea hana a me ka ʻāpana o ka ʻāpana i ka wā o ke kaʻina hana, ka deformation plastic o ka metala ʻili i ka wā e hoʻokaʻawale ʻia ai nā pahu, ka haʻalulu kiʻekiʻe i ka ʻōnaehana kaʻina. , etc. Ma muli o nā ʻano hana like ʻole a me nā mea hana mea hana, ʻokoʻa ka hohonu, ka nui, ke ʻano a me ke ʻano o nā kaha i waiho ʻia ma ka ʻili i hana ʻia.
Pili loa ka ʻili o ka ʻili i ka hana hoʻohālikelike, ke kūpaʻa ʻana, ka ikaika luhi, ka paʻakikī pili, ka haʻalulu a me ka walaʻau o nā ʻāpana mechanical, a he hopena koʻikoʻi i ke ola lawelawe a me ka hilinaʻi o nā huahana mechanical.
Nā palena loiloi
kiʻekiʻe hiʻona nā ʻāpana
ʻAithmetic mean deviation Ra: ka helu helu o ka waiwai piha o ka contour offset i loko o ka laʻana lr. Ma ke ana maoli, ʻoi aku ka nui o nā helu ana, ʻoi aku ka pololei o Ra.
ʻO ke kiʻekiʻe kiʻekiʻe kiʻekiʻe Rz: ka mamao ma waena o ka laina kiʻekiʻe a me ka laina lalo o ke awāwa.

Ka lōʻihi laʻana
ʻO ka lōʻihi o ka laʻana lr ka lōʻihi o ka laina kuhikuhi i kuhikuhi ʻia no ka loiloi ʻana i ka ʻinoʻino o ka ʻili. Pono e koho ʻia ka lōʻihi o ka laʻana ma muli o ka hoʻokumu ʻana o ka ʻili maoli a me nā hiʻohiʻona o ka ʻāpana, a pono e koho ʻia ka lōʻihi e hōʻike i nā ʻano o ka ʻili. Pono e ana ʻia ka lōʻihi o ka laʻana ma ka ʻaoʻao ākea o ka ʻaoʻao o ka ʻili maoli. Ua koho ʻia ka lōʻihi o ka laʻana no ka palena a hōʻemi i nā hopena o ka hawewe o ka ʻili a hana hewa i nā ana ʻino o ka ʻili.
Ma ke kahua o ka hana mīkini, nā kaha kiʻi me nā ʻāpana stamping metala, nā ʻāpana metala, nā ʻāpana mīkini, etc. No laila, ma nā ʻoihana like ʻole e like me nā ʻāpana kaʻa, nā mīkini ʻenekinia, nā mea lapaʻau, aerospace, a me nā mīkini hana moku, etc. Hiki ke ʻike ʻia nā mea a pau.
