ʻO ke koho ʻana i nā mea hana e hana pū me ka CNC router pono e noʻonoʻo i nā kumu ma mua o ka hapa hope i makemake ʻia. Hoʻopili ʻia nā mea ʻokoʻa i nā ʻano like ʻole e ke alalai, hoʻololi ʻia e ka hopena i hoʻohana ʻia a me nā hoʻonohonoho mīkini. ʻO ke alalai ponoʻī, ʻoi aku ka hopena i hoʻohana ʻia, pili ʻia e ka mea.

2. Laha ʻia ka māwae i loko o ka mokulele o ka pepa - ʻAʻole ma ka delamination.
No ka mea i hāʻule ʻole ma ka delaminating, e ʻoki ʻia nā ʻaoʻao a hoʻopaʻa pololei i ka wā o ke ala. No ka pale ʻana i kēia hopena, ʻōlelo ʻia ka hoʻohana ʻana i kahi hopena hoʻoemi.

Loaʻa nā ʻūhā Polymer no ka hoʻokele CNC, a loaʻa iā ia ka pōmaikaʻi o ka hana ʻana i ka ʻaʻahu ʻike ʻole ʻia ma ka hopena, ʻoiai e ʻae ana i nā ʻano paʻakikī e hana ʻia no ka hoʻopili maʻamau, aesthetics, geometry hoʻāʻo, a i ʻole no ka hana haʻahaʻa. ʻO ka hiʻohiʻona wehewehe o kēia mau mea ʻo ko lākou ikaika shear haʻahaʻa, e ʻae iā lākou e ʻoki wikiwiki a maʻalahi.
Ke koho ʻana i kēia mau mea, inā ʻoi aku ka haʻahaʻa o ka ikaika tensile o ka huʻa ma mua o ka ikaika shear, a laila hiki ke haehae ʻia nā ʻāpana ma kahi o nā ʻāpana ʻoki maʻemaʻe. Hiki nō hoʻi i nā ʻāpana o ka ʻōhuhi ʻano paʻakikī a maʻalahi hoʻi e haehae a ʻōwili i ka hopena o ke alalai.
No nā huʻa kakaʻikahi me kēia pilikia, e hōʻoia e hoʻohana i nā wēlau ʻoki ʻokiʻoki i ka RPM kiʻekiʻe me nā awāwa ʻino, ʻaʻole nā hopena abrasive a pāpaʻu paha. Hiki ke ʻoki ʻia nā ʻōhuʻa ʻoʻoleʻa ma mua o ka ʻoki ʻana i mea e pale ʻole ai lākou.
Nā Paʻi Paʻaleʻa
Ua wehewehe ʻia nā plastic plastic palupalu (e like me ka polyethylene haʻahaʻa haʻahaʻa) e kahi ana pili: He mau polymers e hoʻopuka i nā "curls", a i ʻole nā ʻāpana lōʻihi loa, ke ʻoki ʻia. ʻO ia hoʻi, ʻoi aku ka paʻakikī a ʻoi aku ka ductile. E hoʻomanaʻo, ʻoi aku ka liʻiliʻi o kahi ʻilika palupalu, a e nalowale ka hoʻomanawanui ʻana ma ke ʻoki ʻana i ka wā wela.

ʻO nā plastic paʻa (e like me ka poly methyl-methacrylate) ua wehewehe ʻia e kahi ana pili: Hoʻopuka lākou i nā ʻāpana pōkole me nā kihi haʻihaʻi ke ʻoki ʻia. 'O ia ke 'ano o ka 'o'ole'a a 'oki 'ia me nā 'ao'ao li'ili'i 'ole, no ka mea, 'oi aku ka ma'alahi o ka wehe 'ana i nā mea li'ili'i. Eia nō naʻe, hiki ke maʻalahi ka overheating i kahi pilikia.
ʻOi aku ka liʻiliʻi o nā plastik paʻa i ka nui ke wela, akā hiki ke hoʻoheheʻe a hoʻohaʻahaʻa paha ma ka ʻaoʻao o ka ʻokiʻoki, e hoʻoulu ai i nā mea i hoʻomaloʻo ʻia ma ka hopena o ke alalai a pale iā ia mai ka ʻoki ʻana. E ho'ēmi i kēia manaʻo me kahi mahana ambient ʻoluʻolu, nā pā, a me nā ʻoki pāpaʻu.
Nā ʻano o nā ʻili
• Acrylic: Akaka, waihoʻoluʻu, ikaika.
• Polycarbonate: Ke kū'ē i ka hopena kiʻekiʻe, maopopo.

I ka hapa nui o nā kūlana, ʻo ka metala wale nō e ʻoki ʻia me kahi alalai he alumini. He paʻakikī loa kekahi mau ʻāpana kiʻekiʻe-Si o Al, a pono e hoʻohana wale ʻia i nā wili.
Hoʻopuka ka alumini i nā curl lōʻihi ke ʻoki ʻia me nā hopena maʻamau, e hopena pinepine i ka jamming inā ʻaʻole i loaʻa ka nui o ka ʻae. Ke ʻoki ʻia ka alumini me ka hoʻomanawanui liʻiliʻi, pono e hoʻohana ʻia kahi hopena chipbreaker kūikawā. ʻO kēia ʻano hopena, me nā waiwai ma waena o nā ʻāpana abrasive a me nā ʻoki ʻoki he nui, he "diamond" rhombohedral surface pattern e pale ai i kahi ʻoki ʻoki hoʻokahi mai ka hoʻopili ʻana me ka nui o nā mea i ka wā o ka ʻoki ʻoki holoʻokoʻa.
E makaʻala i ka paʻakikī a me ka hoʻoheheʻe ʻana o ka metala i ka wela a no laila e loli paha nā hoʻonohonoho kūpono no kāu mea alalai inā ʻaʻole mālama ʻia ka mahana o kāu wahi hana. Ke ulu ka wela, pau ka hopena ma ka wikiwiki ma muli o ka palupalu, a lilo ka ʻili o ka metala i ʻoi aku ka ductile, kahi e hoʻololi ai i ka "smearing" ma kahi o nā ʻoki maʻemaʻe. E ʻoki mālie a hoʻohana i nā mea pā hoʻomaha.
I nā hihia koʻikoʻi, hiki ke hoʻokuʻu ʻia nā metala ʻē aʻe ma waho o ka alumini.
- He palupalu kekahi mau ala keleawe e hoʻokele ʻia me ka mālama nui, koho i nā hopena paʻakikī loa a me nā ala CNC i hoʻolālā ʻia no ia kumu.
- Ma ka manaʻo, hiki ke hoʻokuʻu ʻia nā metala palupalu loa e like me ke keleawe maʻemaʻe, ke gula, a i ʻole ke kēpau.
- I ka hihia o kahi mea paʻa, ʻoluʻolu loa e like me nā metala maʻemaʻe palupalu, e koho i nā hopena ʻokiʻoki me nā ʻohe liʻiliʻi.

Nā ʻano metala
• Aluminum: Māmā, pale ʻino.
• keleawe: Mea hoʻonani, maʻalahi e ʻoki.
• Ke kila: ikaika, paʻa.
• Copper: Conductive, palupalu.
Pōhaku a me Keramika
ʻO nā mea ʻoʻoleʻa, ʻoʻoleʻa me ka ʻoʻoleʻa haʻahaʻa e like me ka pōhaku sedimentary a me ka keramika maʻamau (granite, sandstone, tile) hiki ke hoʻolei ʻia me nā welau abrasive paʻakikī.
Hana pinepine ʻia kēia mau hopena me ka metala me nā ʻāpana daimana i hoʻopili ʻia e like me ka abrasive. No ka ʻeleʻele haʻahaʻa haʻahaʻa, hiki ke kūpono i ka hopena pāpaʻu, ʻōheʻe, a i ʻole ka ʻoki ʻoki i hana ʻia me ka HSS a i ʻole ka carbide.
ʻO ka mea maʻamau, hoʻohana ʻia kahi router CNC no kēia mau mea i ka wā e pono ai nā kikoʻī kikoʻī a i ʻole nā ʻano hiʻohiʻona paʻakikī. Ma muli o ke kiʻekiʻe o ka paʻakikī a me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o nā pōhaku a me nā mea seramika, hana ʻia ka nui o ka wela a he liʻiliʻi loa ka lawe ʻia ʻana e ka ʻili a wehe ʻia nā ʻāpana. 'O ia ho'i, he pilikia nui ka ho'oulu'ana o ka wela ma ka hopena o ke alalai. Paipai ʻia ka hoʻoluʻu wai pololei.
Nā ʻano Pōhaku a me ka Keramiki
• Marble: He nani, he palupalu.
• Granite: Paʻa, paʻa.
• Nā Tile Ceramic: Paʻakikī, palupalu.
No ka hoʻokō ʻana i nā hopena i makemake ʻia i nā papahana router CNC ʻo ka mea kūpono ka mea koʻikoʻi.
