Litšebeliso tsa Lasers Indastering
Selelekela: Ho tloha ha e qala ka bo-1960, theknoloji ea laser e fetohile ka potlako hore e be sesebelisoa sa bohlokoa tlhahisong ea indasteri, ka lebaka la matla a eona a mangata, tataiso e ntle le taolo. Ha e bapisoa le mekhoa ea setso ea ts'ebetso ea mechini, ts'ebetso ea laser e ithorisa ka melemo e ikhethang joalo ka ts'ebetso e sa amaneng, ho nepahala ho hoholo le boiketsetso bo phahameng, 'me e sebelisoa haholo lits'ebetsong tsa tlhahiso ea indasteri ho kenyeletsoa ho seha thepa, ho tjheseletsa, ho tšoaea, ho cheka le tlhahiso ea litlatsetso. Ho latela mefuta ea laser le litšobotsi tsa eona tsa ts'ebetso, ts'ebetso ea laser ea indasteri e arotsoe haholo ka mefuta e meraro: ho seha laser, ho tjheseletsa laser le tlhahiso ea litlatsetso ea laser, e 'ngoe le e 'ngoe e na le mekhoa e ikhethang ea ts'ebetso le li-scope tsa ts'ebeliso.
Ho Seha ka Laser
Ho seha ka laser ke e 'ngoe ea lits'ebetso tsa laser ea indasteri tse hōlileng ka ho fetisisa. E sebelisa mahlaseli a laser a matla a phahameng ho qhibilihisa le ho etsa hore thepa e be mouoane, 'me e sebelisana le likhase tse thusang ho foka slag e qhibilihisitsoeng, e leng se etsang hore ho sehe ho be bonolo le ho nepahetseng. Hona joale, li-laser tsa CO₂ le li-laser tsa fiber ke lisebelisoa tse ka sehloohong, tse loketseng ho seha lipoleiti tse mahareng le tse tšesaane tsa tšepe ea carbon, tšepe e sa ruseng, motsoako oa aluminium le lisebelisoa tse ling. Theknoloji ena e khetholloa ka kerf e moqotetsane, sebaka se senyenyane se amehileng ke mocheso, ha ho hlokahale hlobo le ho fetola litsela tsa ts'ebetso kapele, e leng se etsang hore e sebetse haholo-holo liindastering tse batloang haholo joalo ka tlhahiso ea likoloi, ts'ebetso ea tšepe ea lakane le sefofane.
(1) Tlhahisong ea likoloi, ho seha ka laser ho sebelisoa ho hlahisa likarolo tse fapaneng ho tloha ho liphanele tsa 'mele ho ea ho lienjine. Mohlala, li-laser tsa fiber li sebelisoa bakeng sa ho seha likarolo tsa tšepe tse matla haholo ka nepo, ka hona ho phethahatsa moralo o bobebe oa likoloi.
(2) Indasteri ea lifofane e boetse e rua molemo theknolojing ea ho seha ka laser, haholo-holo tlhahisong ea likarolo tse rarahaneng tse entsoeng ka thepa e tsoetseng pele joalo ka titanium le thepa e kopaneng. Mohlala, li-laser tse potlakileng haholo li ka sebelisoa ho seha likarolo tsa motsoako oa titanium tse bōpehileng joaloka motsoako ha li ntse li fokotsa tšenyo ea mocheso, ho netefatsa botšepehi ba sebopeho sa likarolo le ho ntlafatsa haholo ts'ebetso le polokeho ea likarolo tsa lifofane.
Ho tjheseletsa ka laser
Ho tjheseletsa ka laser ho fihlella ho kopanya thepa ka ho sebedisa mahlasedi a laser ho qhibilihisa thepa ya tshepe ka potlako, e nang le ho kenella ho tebileng, lebelo le phahameng le ho kenya mocheso o tlase. Mekhoa e tlwaelehileng ya ho tjheseletsa e kenyelletsa ho tjheseletsa ka laser e tswelang pele le ho tjheseletsa ka laser e pulsed, e loketseng ho tjheseletsa ka nepo dipoleiti tse tshesane le maemo a ho tjheseletsa ka botebo. Ha ho bapiswa le ho tjheseletsa ka arc, ho tjheseletsa ka laser ho hlahisa di-weld tse nang le matla a phahameng le phetoho e nyane, mme e sebetsa masimong a kang ho paka betri ya motlakase, ho tjheseletsa dikarolo tsa tshepe e sa ruseng le tlhahiso ya dikarolo tsa meaho ya matla a nyutlelie. Haholo-holo tlhahisong ya betri, ho tjheseletsa ka laser e se e le mokgwa o ka sehloohong wa kgokelo.
(1) Indastering ea likoloi, ho tjheseletsa ka laser ho sebelisoa ho kopanya liphanele tsa 'mele, likarolo tsa enjene le likarolo tse ling tsa bohlokoa. Mohlala, li-laser tsa fiber li sebelisoa bakeng sa ho tjheseletsa ka nepo likarolo tsa tšepe tse matla haholo, ho etsa manonyeletso a tiileng le a tšoarellang.
(2) Indastering ea lisebelisoa tsa elektroniki, ho tjheseletsa ka laser ho sebelisoa khokahanong e nepahetseng haholo ea likarolo tse nyane le tse bonolo. Mohlala, li-laser tsa diode li sebelisoa ho tjheseletsa lisele tsa betri libetering tsa lithium-ion, ho netefatsa ho tšepahala ha likhokahano tsa motlakase.
(3) Indastering ea lifofane, Boeing 787 Dreamliner e sebelisa theknoloji ea ho tjheseletsa ka laser ho kopanya li-alloy tsa titanium le thepa e kopaneng, e leng se fokotsang palo ea li-rivets haholo, se fokotsa boima ba fuselage le ho ntlafatsa ts'ebeliso e ntle ea mafura.
Tlhahiso ea ho Eketsa ea Laser
Tlhahiso ea lisebelisoa tsa laser (e leng khatiso ea laser ea 3D) e phethahatsa ho beoa ha meaho e rarahaneng ka mekhahlelo ka mekhahlelo ka ho qhibilihisa phofo kapa thepa ea terata lera ka lera, e emelang phetoho ea mekhoa ea tlhahiso ho tloha "tlhahisong e tlosang" ho ea "tlhahisong e eketsang".Mekhoa ea tlhahiso ea litlatsetso e thehiloeng ho laser, tse kang ho qhibiliha ha laser e khethiloeng (SLM) le ho beoa ha tšepe ka kotloloho (DMD), li khona ho hlahisa likarolo tse rarahaneng tsa tšepe ka ho nepahala ho hoholo le matla a phahameng. Ha ho bapisoa le ts'ebetso ea setso, tlhahiso ea lisebelisoa tsa laser e ka phethahatsa moralo o kopaneng oa ho bopa le o bobebe oa meaho e rarahaneng ha e ntse e boloka matla a thepa.
(1) Tlhahisong ea likoloi, likarolo tsa motsoako oa titanium tsa likoloi tsa mabelo tsa Ferrari F1 li etsoa ho sebelisoa theknoloji ea tlhahiso ea lisebelisoa tsa laser, e ntlafatsang khanyetso ea mocheso le matla a likarolo le ho ntlafatsa moralo oa moea oa likoloi tsa mabelo.
(2) Indastering ea bongaka, tlhahiso ea lisebelisoa tse thehiloeng ho laser e sebelisoa ho hlahisa li-implant le li-prosthetics tse ikhethileng.
(3) Indastering ea lifofane, tlhahiso ea litlatsetso e thehiloeng ho laser e sebelisoa tlhahisong ea likarolo tse rarahaneng tse kang mahare a turbine le li-nozzle tsa mafura.
Qetello
Jwalo ka tshiya ya bohlokwa ya tlhahiso e tswetseng pele, theknoloji ya laser e ntse e atolosa meedi ya yona ya ditshebediso tsa diindasteri ka mehla. Hona jwale, tshebetso ya laser e ntse e tswela pele ho ya ho matla a phahameng, ho nepahala ho hoholo le ho kopanya ditsamaiso tse ngata, jwalo kaho tjheseletsa ha lebasetere ka laser-arc, ho sebetsa ka machine e potlakileng haholo ea laser le litsamaiso tsa tlhokomelo tse bohlale tsa laser. Nakong e tlang, ka tsoelo-pele e tsoelang pele ea li-laser tsa semiconductor tse matla a holimo, litsamaiso tsa taolo tse bohlale le likhopolo tsa tlhahiso e tala, ts'ebetso ea laser e tla tsoela pele ho bapala karolo ea bohlokoa masimong a kang tlhahiso e bohlale, lihlahisoa tse ikhethileng le ts'ebetso e feteletseng ea thepa.
