Ke koi mau nei ka hana ʻana i ka ʻoi aku ka pololei a me ka huahana,laser alakaʻi wai-jet (WJGL)Ke piʻi nei ka wikiwiki o ka ʻenehana ma ka hoʻohana ʻana i ka ʻenekinia a me ka hiki ke kūʻai aku. Ma nā ʻāpana kiʻekiʻe e like me ka aerospace, nā mea uila, nā mea lapaʻau, a me ka hana ʻana i nā kaʻa, ua kau ʻia nā koi koʻikoʻi ma ka pololei o ka dimensional, ka pono o ka lihi, ka mana o ka ʻāpana i hoʻopilikia ʻia e ka wela (HAZ), a me ka mālama ʻana i nā waiwai o nā mea. ʻO nā kaʻina hana maʻamau—ka mīkini mīkini, ka ʻoki wela, a me ka hana laser maʻamau—e hakakā pinepine me ka hopena wela nui, ka microcracking, a me ka palena palena o ka launa pū ʻana me nā mea ʻālohilohi loa a i ʻole nā mea ʻike wela.

No ka hoʻoponopono ʻana i kēia mau palena, ua hoʻokomo nā mea noiʻi i kahi jet wai micro wikiwiki i loko o ke kaʻina hana laser, e hana ana iā WJGL. Ma kēia hoʻonohonoho ʻana, lawelawe ka jet wai i ka manawa like ma ke ʻano hemea hoʻolaha alakaʻi kukunaa me kahimea hoʻomaʻalili/mea wehe ʻōpala kūpono, e hoʻomaikaʻi ana i ka maikaʻi o ka ʻoki a me ka hoʻonui ʻana i ka hoʻohana ʻana i nā mea. Ma ke ʻano he manaʻo, ʻo WJGL kahi hui hou o ka hana laser kuʻuna a me ka ʻoki ʻana i ka wai-jet, e hāʻawi ana i ka nui o ka ikehu, ke kiko kiʻekiʻe, a me ka hōʻemi nui ʻia o ka pōʻino wela - nā ʻano e kākoʻo ana i kahi ākea o nā hiʻohiʻona hana kikoʻī.

Mīkini Hana Laser i alakaʻi ʻia e ka Micro Waterjet

Kumumanaʻo Hana o ka Laser Alakaʻi Wai-Jet

E like me ka mea i hōʻike ʻia ma ke Kiʻi 1, ʻo ke kumumanaʻo nui o WJGL ka hoʻoili ʻana i ka ikehu laser ma o kahi jet wai hoʻomau, e hana pono ana ma ke ʻano he "fiber optical wai." I loko o nā fiber optical maʻamau, alakaʻi ʻia ka mālamalama eka noʻonoʻo kūloko holoʻokoʻa (TIR)ma muli o ka ʻokoʻa refractive-index ma waena o ke kumu a me ke kapa komo. Hoʻohana ʻo WJGL i ka ʻano hana like ma kaka pilina wai-ea: he ʻaneʻane like ka helu kuhikuhi refractive o ka wai1.33, ʻoiai e pili ana ka ea1.00Ke hoʻopili ʻia ka laser i loko o ka jet ma lalo o nā kūlana kūpono, hoʻopaʻa ʻo TIR i ke kukuna i loko o ke kolamu wai, e hiki ai ke hoʻolaha paʻa a haʻahaʻa i ka ʻāpana machining.

Kiʻi 1 Nā ʻano hana o ka laser alakaʻi wai-jet (schematic)

Hoʻolālā Nozzle a me ke kūkulu ʻana o Micro-Jet

ʻO ka hoʻopili laser kūpono i loko o ka jet e pono ai kahi nozzle e hiki ke hana i kahi micro-jet paʻa, hoʻomau, kokoke i ka cylindrical, ʻoiai e ʻae ana i ka laser e komo i kahi kihi kūpono e mālama i ka TIR ma ka palena wai-ea. Ma muli o ke kūpaʻa o ka jet e hoʻomalu ikaika i ka paʻa o ka hoʻoili kukuna a me ke kūlike o ka nānā ʻana, hilinaʻi pinepine nā ʻōnaehana WJGL i ka kaohi wai pololei a me nā geometries nozzle i hana pono ʻia.

Hōʻike ke Kiʻi 2 i nā kūlana jet i hoʻokumu ʻia e nā ʻano nozzle like ʻole (e laʻa, capillary a me nā hoʻolālā conical like ʻole). Hoʻopilikia ke ʻano o ka nozzle i ka ʻūlū ʻana o ka jet, ka lōʻihi paʻa, ka hoʻomohala ʻana o ka turbulence, a me ka pono o ka hoʻopili ʻana—a pēlā e hoʻopilikia ai i ka maikaʻi o ka machining a me ka hana hou ʻana.

Hōʻike pū ka wai i ka omo ʻana a me ka hoʻopuehu ʻana e pili ana i ka nalu. Ma nā pae ʻike ʻia a kokoke i ka infrared, haʻahaʻa iki ka omo ʻana, e kākoʻo ana i ka hoʻoili pono ʻana. I ka hoʻohālikelike ʻana, piʻi ka omo ʻana ma nā pae infrared mamao a me nā ultraviolet, no laila hana ka hapa nui o nā hoʻokō WJGL ma nā kāʻei ʻike ʻia a kokoke i ka infrared.

Kiʻi 2 Nā ʻano hana nozzle no ka hoʻokumu ʻana i ka micro-jet: (a) kiʻikuhi contraction; (b) nozzle capillary; (c) nozzle conical; (d) nozzle conical luna; (e) nozzle conical lalo

Nā Pōmaikaʻi Koʻikoʻi o WJGL

ʻO nā ala mīkini kuʻuna e komo pū me ka ʻoki mīkini, ka ʻoki wela (e laʻa, plasma/ahi), a me ka ʻoki laser maʻamau. Hoʻopili ʻia ka mīkini mīkini; hiki i ka ʻaʻahu o ka mea hana a me nā ikaika ʻoki ke hoʻoulu i ka micro-damage a me ka deformation, e kaupalena ana i ka pololei hiki ke hiki a me ka kūpaʻa o ka ʻili. He kūpono ka ʻoki wela no nā ʻāpana mānoanoa akā maʻamau ka hana ʻana i ka HAZ nui, nā koʻikoʻi koena, a me nā microcracks e hōʻemi ana i ka hana mīkini. ʻOiai he mea maʻalahi ka hana ʻana i ka laser maʻamau, hiki nō ke ʻeha mai ka HAZ nui a me ka hana paʻa ʻole ma nā mea ʻālohilohi loa a i ʻole nā mea wela-sensitive.

E like me ka hōʻuluʻulu ʻia ma ke Kiʻi 3, hoʻohana ʻo WJGL i ka wai ma ke ʻano he mea hoʻoili a me kahi coolant like, e hōʻemi nui ana i ka HAZ a kāohi i ka distortion a me ka microcracking, a laila e hoʻomaikaʻi ana i ka pololei a me ka maikaʻi o ka lihi/ʻili (e nānā i ke Kiʻi 4). Hiki ke hōʻuluʻulu ʻia kona mau pono penei:

ʻO ka pōʻino wela haʻahaʻa a me ka maikaʻi i hoʻomaikaʻi ʻiaʻO ka mana wela kikoʻī kiʻekiʻe a me ke kahe mau ʻana o ka wai e hoʻopau koke i ka wela, e kaupalena ana i ka hōʻiliʻili ʻana o ka thermal a kōkua i ka mālama ʻana i ka microstructure a me nā waiwai.
Hoʻonui ʻia ke kūpaʻa o ka nānā ʻana a me ka hoʻohana ʻana i ka ikehuʻO ka hoʻopaʻa ʻana i loko o ka jet e hōʻemi ana i ka hoʻopuehu ʻana a me ka nalowale o ka ikehu i hoʻohālikelike ʻia me ka hoʻolaha ʻana o ka hakahaka manuahi, e hiki ai ke kiʻekiʻe o ka nui o ka ikehu a me ka hana ʻana i ʻoi aku ka kūlike—kūpono loa i ka ʻoki maikaʻi, ka micro-drilling, a me nā geometries paʻakikī.
Hana maʻemaʻe a palekana hoʻiHopu a wehe ka mea wai i ka uahi, nā ʻōpala, a me nā ʻōpala, e hōʻemi ana i ka haumia o ka lewa a hoʻomaikaʻi i ka palekana hana.

Nā Wahi Hoʻohana

1) Lewa

Hoʻohana pinepine nā ʻāpana aerospace i nā mea hana kiʻekiʻe e like me nā titanium alloys, nā nickel-based alloys, CFRP, CMC, a me nā keramika, he mea paʻakikī ke mīkini me ka mālama ʻana i ka pololei a me ka pono. Me kona hui pū ʻana o ka ikehu kiʻekiʻe a me ka hoʻoluʻu maikaʻi, hiki iā WJGL ke ʻoki pololei me ka HAZ i hoʻemi ʻia, e hoʻemi ana i ka deformation a me ka hōʻino ʻana o ka waiwai a me ke kākoʻo ʻana i nā ʻāpana koʻikoʻi o ka hilinaʻi.

2) Nā Mea Lapaʻau

Pono ka hana ʻana i nā mea lapaʻau i ka pololei loa, ka maʻemaʻe, a me ka pono o ka ʻili no nā huahana e like me nā mea hana minimally invasive, nā implants, a me nā mea hana diagnostic/therapeutic. Ma ka hoʻoluʻu ʻana a me ka hoʻomaʻemaʻe ʻana i ka ʻāpana mīkini me ke kahe wai, hōʻemi ʻo WJGL i ka pōʻino wela a me ka haumia o ka ʻili, e hoʻomaikaʻi ana i ke kūlike a me ke kākoʻo ʻana i ka biocompatibility. Hiki nō hoʻi iā ia ke hana pololei i nā geometries paʻakikī no nā mea hana i hana ʻia.

3) Nā mea uila

I ka hana ʻana o ka microelectronics a me ka semiconductor, hoʻohana nui ʻia ʻo WJGL no ka dicing wafer, ka hoʻopili ʻana i nā chip, a me ka micro-structuring ma muli o kona pololei kiʻekiʻe a me ka hopena wela haʻahaʻa. Hoʻēmi ka hoʻoluʻu wai i ka pōʻino i hoʻoulu ʻia e ka wela i nā ʻāpana koʻikoʻi, e hoʻomaikaʻi ana i ka hilinaʻi a me ke kūpaʻa o ka hana.

4) Hana ʻana i ka mīkini daimana

No ke daimana a me nā ʻāpana mea paʻakikī loa ʻē aʻe, hāʻawi ʻo WJGL i ka ʻoki a me ka wili pololei me ka hopena wela haʻahaʻa, ka pilikia mechanical liʻiliʻi, ka pono kiʻekiʻe, a me ka maikaʻi o ka lihi/ʻili. Ke hoʻohālikelike ʻia me nā ʻano hana mechanical maʻamau a me kekahi mau ʻano hana laser, ʻoi aku ka maikaʻi o WJGL i ka mālama ʻana i ka pono o nā mea a me ka hoʻopau ʻana i nā hemahema.

Nā nīnau i nīnau pinepine ʻia no ka Laser Alakaʻi Wai-Jet (WJGL)

1) He aha ka mīkini ʻana o ka Water-Jet Guided Laser (WJGL)?

He ʻano hana laser ʻo WJGL kahi e hoʻopili ʻia ai ke kukuna laser i loko o kahi jet wai liʻiliʻi. Hana ka jet wai ma ke ʻano he mea alakaʻi kukuna a me kahi mea hoʻoluʻu/wehe ʻōpala, e hiki ai ke kiʻekiʻe kiʻekiʻe me ka hōʻemi ʻana i ka pōʻino wela.

2) Pehea e hana ai ʻo WJGL?

Hilinaʻi ʻo WJGL i ka hoʻohuli kūloko holoʻokoʻa ma ka pilina wai-ea. No ka mea he ʻokoʻa nā ʻōkuhi refractive o ka wai a me ka ea, hiki ke hoʻopaʻa ʻia a alakaʻi ʻia ka laser i loko o ke kolamu wai—e like me ka "liquid optical fiber"—a hāʻawi paʻa ʻia i ka ʻāpana machining.

3) No ke aha e hōʻemi ai ʻo WJGL i ka ʻāpana i hoʻopilikia ʻia e ka wela (HAZ)?

Hoʻopau pono ka wai e kahe mau ana i ka wela ma muli o kona hiki ke wela kiʻekiʻe. Hoʻopau kēia i ka hōʻiliʻili ʻana o ka wela, e hōʻemi ana i ka HAZ, ka distortion, a me ka microcracking.

4) He aha nā pono nui e kū'ē i ka hana laser maʻamau?

ʻO nā pono nui e komo pū ana me:

Hoʻemi ʻia a ʻaʻohe koi hoʻihoʻi hou ʻana; kūpono no ka ʻoki ʻana ʻaʻole planar/3D
ʻOi aku ka kūlike o nā paia kerf like a me ka maikaʻi o ka ʻoki ʻana
Ka hopena wela haʻahaʻa loa (HAZ liʻiliʻi)
Ka hana ʻana maʻemaʻe: hopu ka wai i nā particulates a kōkua i ka pale ʻana i ka waiho ʻana/haumia
ʻOi aku ka liʻiliʻi o ka hoʻokumu ʻana o ka burr: kōkua ka jet i ka hoʻokuke ʻana i nā mea i hoʻoheheʻe ʻia mai ke kerf
