Isingeniso

Njengoba ukukhiqiza kuqhubeka nokudinga ukunemba okuphezulu kanye nokukhiqiza,i-laser eqondiswa yi-water-jet (WJGL)ubuchwepheshe bukhula ngamandla kokubili ekwamukelweni kobunjiniyela kanye namathuba emakethe. Emikhakheni ephezulu njengezindiza, izinto zikagesi, amadivayisi ezokwelapha, kanye nokukhiqizwa kwezimoto, izidingo eziqinile zibekwa ekuqondeni ubukhulu, ubuqotho bomphetho, ukulawulwa kwendawo ethintekile ekushiseni (HAZ), kanye nokulondolozwa kwezakhiwo zezinto ezibonakalayo. Izinqubo ezivamile—ukusebenza ngomshini, ukusika ukushisa, kanye nokucubungula i-laser ejwayelekile—kuvame ukuba nzima ngomthelela omkhulu wokushisa, ukuqhekeka okuncane, kanye nokuhambisana okulinganiselwe nezinto ezibonisa kakhulu noma ezizwela ukushisa.

Ukuze kuxazululwe lezi zingqinamba, abacwaningi bethule i-micro water jet esheshayo enqubweni ye-laser, okwadala i-WJGL. Kulokhu kulungiselelwa, i-water jet isebenza ngesikhathi esisodwa njenge-indawo eqondisa imisebekanyeindawo yokususa udoti/imfucumfucu esebenzayo, ukuthuthukisa ikhwalithi yokusika kanye nokwandisa ukusetshenziswa kwezinto. Ngomqondo, i-WJGL iyinhlanganisela entsha yokucubungula i-laser yendabuko kanye nokusika nge-water-jet, enikeza amandla amaningi, ukunemba okuphezulu, kanye nomonakalo wokushisa oncishisiwe kakhulu—izimfanelo ezisekela izimo eziningi zokukhiqiza ngokunemba.

Isimiso Sokusebenza Se-Laser Eqondiswa Yi-Water-Jet

Njengoba kuboniswe ku-Fig. 1, umqondo oyinhloko we-WJGL ukudlulisa amandla e-laser nge-water jet eqhubekayo, esebenza ngempumelelo njenge-"liquid optical fiber." Kuma-optical fibers avamile, ukukhanya kuqondiswa yi-ukubonakaliswa kwangaphakathi okuphelele (i-TIR)ngenxa yomehluko wenkomba yokukhanya phakathi kwe-core kanye ne-cladding. I-WJGL isebenzisa indlela efanayo ku-isikhombikubona samanzi nomoya: amanzi anenkomba yokubuyisa cishe1.33, ngenkathi umoya useduze1.00Uma i-laser ihlanganiswa nejethi ngaphansi kwezimo ezifanele, i-TIR ivala umsebe ngaphakathi kwekholomu yamanzi, okwenza kube lula ukusabalala okuzinzile, okuphansi endaweni yomshini.

Umklamo Wezimbobo Nokwakheka Kwe-Micro-Jet

Ukuhlanganiswa kwe-laser okuphumelelayo ejethini kudinga i-nozzle ekwazi ukukhiqiza i-micro-jet ezinzile, eqhubekayo, ecishe ibe yi-cylindrical, ngenkathi ivumela i-laser ukuthi ingene nge-engeli efanele ukugcina i-TIR emngceleni wamanzi nomoya. Ngenxa yokuthi ukuqina kwe-jet kulawula kakhulu ukuqina kokudluliselwa kwe-beam kanye nokuvumelana okugxile, izinhlelo ze-WJGL zivame ukuthembela ekulawulweni koketshezi okunembile kanye nama-geometri e-nozzle aklanywe ngokucophelela.

Isithombe 2 sibonisa izimo zejethi ezimele ezikhiqizwa izinhlobo ezahlukene ze-nozzle (isb., imiklamo ye-capillary kanye nemiklamo ehlukahlukene ye-conical). I-geometry ye-nozzle ithonya ukufinyela kwejethi, ubude obuzinzile, ukuthuthukiswa kwe-turbulence, kanye nokusebenza kahle kokuxhumanisa—ngaleyo ndlela kuthinta ikhwalithi yomshini kanye nokuphindaphindwa kwawo.

Amanzi aphinde abonise ukumuncwa kanye nokusabalala okuncike kubude be-wavelength. Ezindaweni ezibonakalayo neziseduze kwe-infrared, ukumuncwa kuphansi kakhulu, okusekela ukudluliselwa okuphumelelayo. Ngokuphambene nalokho, ukumuncwa kuyanda ezindabeni ze-infrared ezikude kanye ne-ultraviolet, ngakho-ke ukusetshenziswa okuningi kwe-WJGL kusebenza ezindindini ezibonakalayo neziseduze kwe-infrared.

Izinzuzo Eziyinhloko ze-WJGL

Izindlela zendabuko zomshini zifaka phakathi ukusika ngomshini, ukusika ngokushisa (isb., i-plasma/ilangabi), kanye nokusika nge-laser okuvamile. Umshini womshini usekelwe ekuthinteni; ukuguguleka kwamathuluzi namandla okusika kungabangela umonakalo omncane kanye nokuguqulwa, kunciphise ukunemba okufinyelelekayo kanye nobuqotho bomphezulu. Ukusika ngokushisa kusebenza kahle ezingxenyeni ezijiyile kodwa ngokuvamile kukhiqiza i-HAZ enkulu, ukucindezeleka okusele, kanye nemifantu emincane enciphisa ukusebenza ngomshini. Ukucubungula nge-laser okuvamile, yize kunokuguquguquka, kungase kusahlushwa yi-HAZ enkulu kanye nokusebenza okungazinzile ezintweni ezikhanyayo kakhulu noma ezizwela ukushisa.

Njengoba kufingqiwe ku-Fig. 3, i-WJGL isebenzisa amanzi njengendlela yokudlulisa kanye ne-coolant ehambisanayo, inciphisa kakhulu i-HAZ futhi icindezela ukuphambuka kanye nokuqhekeka okuncane, ngaleyo ndlela ithuthukise ukunemba kanye nekhwalithi yomphetho/yomphezulu (bheka i-Fig. 4). Izinzuzo zayo zingafingqiwe kanje:

Umonakalo ophansi wokushisa kanye nekhwalithi ethuthukisiwe: Umthamo wokushisa ophezulu kanye nokugeleza kwamanzi okuqhubekayo kususa ukushisa ngokushesha, kunciphisa ukuqongelela kokushisa futhi kusiza ekulondolozweni kwesakhiwo esincane kanye nezakhiwo.
Ukuqina kokugxila okuthuthukisiwe kanye nokusetshenziswa kwamandla: Ukuvalelwa ngaphakathi kwendiza kunciphisa ukuhlakazeka kanye nokulahlekelwa amandla uma kuqhathaniswa nokusabalala kwesikhala esikhululekile, okuvumela ukuminyana kwamandla okuphezulu kanye nokucubungula okuqhubekayo—kufanele kakhulu ukusika okuncane, ukubhoboza okuncane, kanye namajiyometri ayinkimbinkimbi.
Ukusebenza okuhlanzekile nokuphephile: Le ndawo yamanzi ibamba futhi isuse umusi, izinhlayiya, kanye nemfucumfucu, inciphisa ukungcola emoyeni futhi ithuthukise ukuphepha emsebenzini.

Izindawo Zokufaka Isicelo

1) Izindiza

Izingxenye zezindiza zivame ukusebenzisa izinto zokusebenza okuphezulu njenge-titanium alloys, i-nickel-based alloys, i-CFRP, i-CMC, kanye ne-ceramics, okuyinselele ukuyifaka emshinini ngenkathi kugcinwa ukunemba nokusebenza kahle. Ngokuhlangana kwayo namandla aphezulu kanye nokupholisa okuphumelelayo, i-WJGL ivumela ukusika okunembile nge-HAZ encishisiwe, inciphisa ukuguquguquka kanye nokuwohloka kwempahla futhi isekele izingxenye ezibalulekile zokuthembeka.

2) Amadivayisi Ezokwelapha

Ukukhiqizwa kwamadivayisi ezokwelapha kudinga ukunemba okumangalisayo, ukuhlanzeka, kanye nobuqotho bomphezulu wemikhiqizo efana namathuluzi angangenisi kakhulu, izinto ezifakwayo, kanye namadivayisi okuxilonga/okwelapha. Ngokupholisa nokuhlanza indawo yomshini ngokugeleza kwamanzi, i-WJGL yehlisa umonakalo wokushisa kanye nokungcola komphezulu, ithuthukise ukuhambisana futhi isekele ukuhambisana kwezinto eziphilayo. Iphinde ivumele ukwenziwa ngokunemba kwamajiyometri ayinkimbinkimbi kumadivayisi enziwe ngokwezifiso.

3) Izinto zikagesi

Ekwenziweni kwe-microelectronics kanye ne-semiconductor, i-WJGL isetshenziswa kabanzi ekuhlukaniseni i-wafer, ekupakisheni ama-chip, kanye nasekuhleleni i-micro-structuring ngenxa yokunemba kwayo okuphezulu kanye nomthelela ophansi wokushisa. Ukupholisa amanzi kunciphisa umonakalo obangelwa ukushisa ezingxenyeni ezibucayi, kuthuthukisa ukuthembeka kanye nokuqina kokusebenza.

4) Ukushintshwa Kwedayimane

Ngezingxenye zezinto zedayimane nezinye eziqinile kakhulu, i-WJGL inikeza ukusika nokubhoboza okunembe kakhulu okunomthelela ophansi wokushisa, ukucindezeleka okuncane komshini, ukusebenza kahle okuphezulu, kanye nekhwalithi ephezulu yomphetho/yomphezulu. Uma kuqhathaniswa nezindlela ezivamile zomshini kanye namanye amasu e-laser, i-WJGL ivame ukusebenza kangcono ekugcineni ubuqotho bezinto kanye nokucindezela amaphutha.

Imibuzo Evame Ukubuzwa Nge-Water-Jet Guided Laser (WJGL)

1) Kuyini ukushintshwa kwe-Water-Jet Guided Laser (WJGL)?

I-WJGL iyindlela yokucubungula nge-laser lapho umsebe we-laser uhlanganiswa khona ube yi-micro water jet. I-water jet isebenza njenge-medium eqondisa imisebe kanye ne-cooling/debris-removal medium, okwenza kube nokunemba okuphezulu kanye nomonakalo ophansi wokushisa.

2) Isebenza kanjani i-WJGL?

I-WJGL ithembele ekukhanyeni kwangaphakathi okuphelele esibonakalayo samanzi nomoya. Ngenxa yokuthi amanzi nomoya kunezinkomba zokukhanya ezihlukile, i-laser ingavalwa futhi iqondiswe ngaphakathi kwekholomu yamanzi—njenge-“liquid optical fiber”—futhi ithunyelwe ngokuzinzile endaweni yomshini.

3) Kungani i-WJGL inciphisa indawo ethinteke ekushiseni (i-HAZ)?

Amanzi ageleza njalo asusa ukushisa kahle ngenxa yamandla awo aphezulu okushisa. Lokhu kuvimbela ukuqongelela kokushisa, kunciphisa i-HAZ, ukuphambuka, kanye nokuqhekeka okuncane.

4) Yiziphi izinzuzo eziyinhloko uma kuqhathaniswa nokucutshungulwa kwe-laser okuvamile?

Izinzuzo ezibalulekile ngokuvamile zifaka:

Izidingo zokuphinda zigxile kancane noma azikho nhlobo; zilungele ukusika okungahleliwe/okuyi-3D
Izindonga ze-kerf ezihambisanayo, ezihambisanayo kanye nekhwalithi yokusika ethuthukisiwe
Umthelela wokushisa ophansi kakhulu (i-HAZ encane)
Ukucubungula okuhlanzekile: amanzi abamba izinhlayiya futhi asiza ekuvimbeleni ukubola/ukungcola
Ukwakheka okuncane kwe-burr: i-jet isiza ukukhipha izinto ezincibilikisiwe e-kerf
