He aha ka ʻoki ʻana i ka laser?

ʻO ka ʻoki laser kahi ʻano ʻoki wela e hoʻohana ana i kahi kukuna laser mana kiʻekiʻe i kālele ʻia e hoʻomālamalama i ka ʻāpana hana. ʻO kēia ke kumu o ka mea i hoʻomālamalama ʻia e hoʻoheheʻe koke, mahu, ablate, a hiki paha i kona wahi hoʻā. I kēia manawa, ʻo ka ea wikiwiki coaxial me ke kukuna laser e puhi aku i ka mea i hoʻoheheʻe ʻia, a laila e ʻoki ana i ka ʻāpana hana.

Ka Hoʻokaʻawale ʻana a me nā ʻAno o ka ʻOki Laser

Hiki ke hoʻokaʻawale ʻia ka ʻoki ʻana i ka laser i ʻehā mau ʻano: ka ʻoki ʻana i ka vaporization laser, ka ʻoki ʻana i ka fusion laser, ka ʻoki ʻana i ka oxygen laser, a me ka laser scribing a me ka haki i kāohi ʻia.

ʻOki ʻana i ka vaporization laser

Hoʻohana ia i kahi kukuna laser me ka ikehu kiʻekiʻe e hoʻomehana i ka ʻāpana hana, e hoʻokiʻekiʻe koke ana i kona mahana i ka wela o ka mea i loko o kahi manawa pōkole loa, e hoʻoulu ai i ka mea e mahu a hana i ka mahu. Hoʻokuʻu ʻia ka mahu ma ka wikiwiki kiʻekiʻe, e hana ana i kahi ʻoki i loko o ka mea i kona pakele ʻana. No ka mea he nui ka wela o ka mahu, pono ka ʻoki ʻana i ka mahu laser i ka mana nui a me ka nui o ka mana.

ʻOki ʻana i ka Fusion Laser

I ka ʻoki ʻana i ka fusion laser, hoʻomehana ka laser a hoʻoheheʻe i ka mea metala. A laila puhi ʻia kahi kinoea non-oxidizing (e like me Ar, He, N, a pēlā aku) ma o kahi nozzle coaxial me ke kukuna laser. Hoʻokuke ke kaomi kiʻekiʻe o ke kinoea i ka metala i hoʻoheheʻe ʻia, e hana ana i kahi ʻoki. ʻAʻole like me ka ʻoki vaporization, ʻaʻole koi kēia ʻano hana i ka vaporization piha o nā mea a hoʻopau wale i ka 1/10 o ka ikehu e pono ai no ka ʻoki vaporization. Hoʻohana nui ʻia ia no ka ʻoki ʻana i nā metala non-oxidizable a reactive paha, me ke kila kila, titanium, alumini, a me kā lākou mau mea hoʻohui.

ʻOki ʻokikene laser

Ua like ke kumumanaʻo o ka ʻoki ʻana i ka oxygen laser me ka ʻoki ʻana i ka oxyacetylene. Hana ka laser ma ke ʻano he kumu wela hoʻomehana mua, ʻoiai nā kinoea hana (e like me ka oxygen) e lawelawe ma ke ʻano he kinoea ʻoki. Ma kekahi ʻaoʻao, hana ka kinoea i puhi ʻia me ka metala e ʻoki ʻia ana, e hoʻoulu ana i kahi hopena oxidation e hoʻokuʻu i ka nui o ka wela oxidation. Ma kekahi ʻaoʻao, puhi ia i nā oxides i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia mai ka ʻāpana hopena, e hana ana i kahi ʻoki i loko o ka metala. Hoʻoulu ka hopena oxidation i ka wā ʻoki i ka wela nui, no laila ʻo ka ʻoki ʻana i ka oxygen laser e pono ai ka hapalua o ka ikehu o ka ʻoki fusion, ʻoiai ʻoi aku ka wikiwiki o kona wikiwiki ʻoki ma mua o ka vaporization a me ka ʻoki fusion. Hoʻopili nui ʻia ia i nā mea metala oxidizable e like me ke kila kalapona, ke kila titanium, a me ke kila i mālama ʻia i ka wela.

Ka Scribing Laser a me ka Fracture i kāohi ʻia

Hoʻohana ka laser scribing i kahi laser ikehu kiʻekiʻe e scan i ka ʻili o nā mea palupalu, e hoʻomaloʻo ana i kahi ʻauwaha liʻiliʻi. ʻO ka hoʻopili ʻana i kahi nui o ke kaomi a laila e hoʻopōʻino i ka mea palupalu ma ke ʻauwaha. Hoʻohana pinepine ʻia nā lasers Q-switched a me nā lasers CO₂ no ka laser scribing. Hoʻohana ka haki i kāohi ʻia i ka hoʻolaha wela kiʻekiʻe i hana ʻia i ka wā o ka laser grooving e hana i ke kaumaha wela kūloko i nā mea palupalu, e hoʻopōʻino ana iā lākou ma ke ʻauwaha i kākau ʻia.

Nā noi o ka ʻoki ʻana i ka laser

Hoʻohana ʻia ka hapa nui o nā mīkini ʻoki laser ma o nā polokalamu mana helu (NC) a i ʻole i hoʻonohonoho ʻia e like me nā robots ʻoki. Ma ke ʻano he ʻano hana kikoʻī, hiki i ka ʻoki laser ke ʻoki i nā mea āpau, me ka ʻoki ʻana 2D a i ʻole 3D o nā pepa metala lahilahi. Ma ke kahua aerospace, hoʻohana nui ʻia ka ʻenehana ʻoki laser no ka ʻoki ʻana i nā mea aerospace kūikawā e like me nā titanium alloys, nā alumini alloys, nā nickel alloys, nā chromium alloys, ke kila kila, ka beryllium oxide, nā mea hui pū ʻia, nā plastics, nā keramika, a me ka quartz. ʻO nā ʻāpana aerospace i hana ʻia e ka ʻoki laser e komo pū me nā paipu lapalapa mīkini, nā pale titanium alloy lahilahi, nā mōlina mokulele, nā ʻili titanium alloy, nā kaula ʻēheu, nā panela ʻēheu huelo, nā rotors nui o ka helikopter, a me nā tile hoʻokaʻawale wela keramika mokulele.
