  Kūpono no nā liʻiliʻi liʻiliʻi, Hōʻike hōʻike'Āina Hana'Iila i kahi, a me nā'āpana likeʻole me keʻano o ka mea kūʻai aku.
• Nā hemahema haʻahaʻa:
  Maheleʻia nā'āpana match, Nāʻuala, a iʻole nā ​​pilikia-maʻamau-maʻamau i ka mālamaʻana.

Cons of cnc machining

• Nā Kūlana Kūʻai:
  Ka mea i hanaʻia, Cnc machining pinepine i nā hopena i loko 50-80% mau mea i nalowale, nui no nā geomet paʻakikī.
• Kumukūʻai kiʻekiʻe no nā holo nui:
  Noho ke kumukūʻai Per-Unit, a me nā mea hana kūpono e hoʻohana hou ai i nā uku hana hana.
• ʻOi aku ka lōʻihi o nā manawa lōʻihi no nā'āpana paʻakikī:
  Hoʻokomoʻia nā geometrate geometurs i nā hoʻonohonoho he nui a iʻole nā ​​mea hana e hoʻonui nui i ka manawa machining.
• ʻO ka paʻakikī o ka paʻakikī:
  He paʻakikī a paʻakikī nā Palekana kūloko a me nā undercuts e hoʻokō me kaʻole o nā mea kūikawā kūikawā, a e koi pinepine i nā papa hana edm a iʻole nā ​​model modular.

E hoʻopau i ka hoʻohālikelike

Cnc iching:

• Ua hana maʻamauʻo CNC makihi i nā'āpana me ʻO nā mea maikaʻi loa e hoʻopau ai, ʻO ka nui o ka hanaʻana i nā ala hana maikaʻi a me nā wikiwiki kiʻekiʻe kiʻekiʻe e hoʻohanaʻia.
• ʻAno maʻamau (Ra) nā waiwai no CNC:

• • ʻO ka hopena maʻamau: Ra ≈ 1.6-3.2 μm
  • Pau loa: Ra ≈ 0.4-0.8 μm
  • ʻO ka hoʻopau maikaʻi loa (E.g., paulapu, Kāleka): Ra ≈ 0.1-0-0.2 μm

• Hoʻemi i nā papa hana hoʻemi Nā mea hana hewa, hoʻonui i ke ola momona, a hoʻomaikaʻi i nā waiwai o ka loaʻa, koʻikoʻi ma Hydraulic a me nā noi aerospace.

Kauhi:

• E like me nā papa i hoʻopaʻaʻia rougher a me ka emi iki Ma muli o nā leka uila, 'ō ai mīkini, a me nā hiʻohiʻona kūpono.

• • Sand cread: RA ≈ 6.3-25 μM
  • Kāhaka kūʻai kūʻai: Ra ≈ 3.2-6.3 μm
  • Make buring: Ra ≈ 1.6-3.2 μm

• Hiki i nā papa'āina Old ONDER, kūkaku, a iʻole nāʻomi, ka mea e hōʻole ai i ka momona momona a me ka corrosioni e kū'ē ana ināʻaʻole i pau.

Subsurface intgrity a me nā hemahema

Cnc iching:

• Matching mai nā huapalapala i hana pinepineʻia huakai, Nā Papahele Homgeneous me ka poosity haʻahaʻa.
• Akā naʻe,, Hiki ke hoʻolaha i nāʻokiʻoki:

• • Nā micro-cracks a iʻole nā'āpana wela (Haz)
  • ʻO nā kaumaha o ke kaumaha, e hōʻemi paha i ke ola momona

• Kāohiʻia me ka ke koho balota Kōkua i ka mālamaʻana i ka kūpaʻa metallirgical.

Kauhi:

• Ua hiki i nā'āpana nā'āpana i nā hemahema subsurface, e like me:

• • Potiwale, ʻO nā pua lāʻau, a me nā kākā shrinkige
  • Nā Hoʻohui (olio, Slag) a Nā'āpana inoa

• Hiki i kēia mau mea hemahema ke hana e like me Nā papa hoʻonohonoho hoʻomaka no nā pale Ma lalo o nā ukana cyclic a iʻole nā ​​hopena koʻikoʻi.

ʻO nā hana hoʻohālike post-ho'ōla

Nā'āpana i nā'āpana CNC:

• Ke hilinaʻi nei i nā koi hana, Hiki i nā'āpana CNC ke hana i nā hoʻomaʻamaʻa hou, e like me:

• • Anodichiz - hoʻomaikaʻi i ke kū'ēʻana (maʻamau i ka alumini)
  • Polokalamu /'ōwili - E hoʻonui i ka papa kuhikuhi a me ka hoʻopauʻana
  • ʻO ka panaʻana - Hoʻomaopopo i nā pilikia koʻikoʻi e hoʻomaikaʻi i ke ola kaumaha
  • Ke hoʻonohonohoʻana / pale (E.g., nickel, chrome, a pvd paha) - Hoʻopili i nā pale pale

Noho ai:

• ʻOi aku ka nui o ka hanaʻana ma muli o ka nui o ka hoʻopiliʻana i kaʻili o ka wai.

• • E kāʻei ana i ka papa a iʻole machining No ka pololei o ka dimensional
  • ʻO ke kaomiʻana o ka wela wela (Hip) - i hoʻohanaʻia Hoʻopau i nā poosity a hoʻonui i ka hōʻino, nui no nā alloys kiʻekiʻe (E.g., ʻO Titanium a me nā mea kūʻai aku)
  • ʻO ka hana wela - E hoʻomaikaʻi i nā microstructure maʻamau a me nā mea waiwai (E.g., T6 no nā mea hoʻokele alumini)
