Nā ʻano ʻoki like ʻole o ka mīkini ʻoki laser

ʻO ka ʻoki ʻana i ka laser kahi ʻano hana hoʻopili ʻole me ka ikehu kiʻekiʻe a me ka mana hoʻopaʻapaʻa maikaʻi.Hoʻokumu ʻia ka wahi laser me ka ikehu kiʻekiʻe ma hope o ka nānā ʻana i ka beam laser, he nui nā ʻano i ka wā e hoʻohana ai i ka ʻoki ʻana.ʻEhā mau ala like ʻole o ka ʻoki ʻana i ka laser no ka hoʻoponopono ʻana i nā kūlana like ʻole.

1.Melt oki　

I ka ʻoki ʻana i ka hoʻoheheʻe ʻana i ka laser, ua hoʻokuʻu ʻia ka mea i hoʻoheheʻe ʻia e ka ea ma hope o ka hoʻoheheʻe ʻia ʻana o ka mea hana ma ka ʻāina.Ma muli o ka hoʻoili ʻana o nā mea i loko o kona ʻano wai, ua kapa ʻia kēia kaʻina hana ʻoki hoʻoheheʻe laser.
ʻO ka kukuna laser me ka maʻemaʻe kiʻekiʻe inert ʻoki kinoea e haʻalele i ka mea hoʻoheheʻe ʻia i ka ʻāpana, ʻoiai ʻaʻole pili ke kinoea ponoʻī i ka ʻoki ʻana.Hiki i ka ʻoki hoʻoheheʻe laser ke kiʻekiʻe i ka wikiwiki o ka ʻoki ʻana ma mua o ka ʻoki gasification.ʻOi aku ka kiʻekiʻe o ka ikehu e pono ai no ka gasification ma mua o ka ikehu e hoʻoheheʻe ai i ka mea.I ka ʻoki ʻana i ka hoʻoheheʻe ʻana i ka laser, ʻāpana wale nō ka kukuna laser.Hoʻonui ka wikiwiki o ka ʻoki ʻana me ka piʻi ʻana o ka mana laser, a emi iho me ka hoʻonui ʻana i ka mānoanoa o ka pā a me ka wela heheʻe.I ka hihia o kekahi mana laser, ʻo ke kumu palena ʻo ia ke kaomi ea ma ka ʻāpana a me ka conductivity thermal o ka mea.No nā mea hao a me ka titanium, hiki i ka ʻoki hoʻoheheʻe laser ke loaʻa nā notches non oxidation.No nā mea kila, aia ka mana o ka laser ma waena o 104w / cm2 a me 105W / cm2.

2.Vaporization ʻoki

I ke kaʻina o ka ʻoki ʻana i ka laser gasification, ʻo ka wikiwiki o ka piʻi ʻana o ka wela o ka ʻili i ka wela o ka paila e hiki ai ke pale aku i ka hoʻoheheʻe ʻia e ka hoʻoheheʻe ʻana i ka wela, no laila e mahuka kekahi mau mea i ka mahu a nalowale, a ua puhi ʻia kekahi mau mea mai ka lalo o ka ʻoki ʻana i ka hili ma ke kahe kinoea kōkua e like me ka ejecta.Pono ka mana laser kiʻekiʻe loa i kēia hihia.

I mea e pale aku ai i ka mahu meahu mai ka condensing ma ka paia slit, aole pono e oi aku ka manoanoa o ka mea ma mua o ke anawaena o ka kukuna laser.No laila, kūpono kēia kaʻina hana no nā noi kahi e pale ʻia ai ka hoʻopau ʻana i nā mea hoʻoheheʻe.ʻO kaʻoiaʻiʻo, hoʻohana waleʻia ke kaʻina hana ma kahi māhele liʻiliʻi loa o ka hoʻohanaʻana i nā mea hao.

ʻAʻole hiki ke hoʻohana ʻia ke kaʻina hana no nā mea e like me ka lāʻau a me kekahi mau seramika, ʻaʻole i loko o kahi ʻano hoʻoheheʻe ʻia a ʻaʻole hiki ke ʻae i ka mahu mea e hui hou.Eia kekahi, pono kēia mau mea e hoʻokō i kahi ʻoki mānoanoa.I ka ʻoki gasification laser, ʻo ka nānā ʻana i ka beam maikaʻi loa e pili ana i ka mānoanoa mea a me ka maikaʻi o ka beam.ʻO ka mana laser a me ka wela o ka vaporization he hopena wale nō ma ke kūlana focal maikaʻi loa.ʻO ke kiʻekiʻe o ka wikiwiki o ka ʻoki ʻana he inversely proportional i ka mahana gasification o ka mea i ka wā e paʻa ai ka mānoanoa o ka pā.ʻOi aku ka nui o ka mana laser e koi ʻia ma mua o 108W / cm2 a hilinaʻi ʻia i ka mea, ka hohonu o ka ʻoki ʻana a me ke kūlana o ka beam.I ka hihia o kahi mānoanoa o ka pā, me ka manaʻo ua lawa ka mana laser, ua kaupalena ʻia ka wikiwiki o ka ʻoki ʻana e ka wikiwiki o ka jet.

3.Controlled ʻoki ʻoki

No nā mea palupalu i maʻalahi e hoʻopōʻino ʻia e ka wela, ua kapa ʻia ka ʻoki ʻoki ʻana i ka ʻoki ʻoki ʻana i ka ʻoki ʻana i ka ʻoki ʻana i ka ʻoki ʻana i ka kukuna laser.ʻO ka mea nui o kēia kaʻina ʻokiʻoki: hoʻomaʻamaʻa ka laser beam i kahi wahi liʻiliʻi o nā mea brittle, kahi e hoʻoulu ai i ka gradient thermal nui a me ka deformation mechanical koʻikoʻi ma kēia wahi, e alakaʻi ana i ka hoʻokumu ʻana o nā māwae i ka mea.ʻOiai ka lōʻihi o ka mālama ʻana i ka gradient hoʻomehana ʻaʻahu, hiki i ka kukuna laser ke alakaʻi i ka hana o nā māwae i kēlā me kēia ʻaoʻao i makemake ʻia.

4.Oxidation melting oki (laser flame oki)

ʻO ka maʻamau, hoʻohana ʻia ke kinoea inert no ka hoʻoheheʻe ʻana a me ka ʻoki ʻana.Inā hoʻohana ʻia ka oxygen a i ʻole ke kinoea hana ʻē aʻe, e hoʻā ʻia ka mea ma lalo o ka irradiation o ka kukuna laser, a e hana ʻia kahi kumu wela ma muli o ka hopena kemika ikaika me ka oxygen e hoʻomaʻamaʻa hou i ka mea, i kapa ʻia ʻo oxidation melting a me ka ʻoki ʻana. .

Ma muli o kēia hopena, hiki ke kiʻekiʻe ke kiʻekiʻe o ka ʻoki ʻana o ke kila kila me ka mānoanoa like ma mua o ka hoʻoheheʻe ʻana.Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o ka incision ma mua o ka ʻokiʻoki heheʻe.ʻO ka ʻoiaʻiʻo, e hoʻopuka ʻo ia i nā ʻāpana ākea, ʻike ʻole ʻia, ʻoi aku ka nui o ka wela a me ka maikaʻi o ka ʻaoʻao.ʻAʻole maikaʻi ka ʻoki ʻana i ka lapalapa laser i ka hana ʻana i nā hiʻohiʻona pololei a me nā kihi ʻoi loa (aia ka pilikia o ke puhi ʻana i nā kihi ʻoi).Hiki ke hoʻohana i nā lasers mode Pulse e kaupalena i nā hopena wela, a ʻo ka mana o ka laser e hoʻoholo i ka wikiwiki o ka ʻoki.I ka hihia o kekahi mana laser, ʻo ka mea palena ʻo ka hāʻawi ʻana i ka oxygen a me ka conductivity thermal o ka mea.
