Ukugxila Kokushisela Nge-Laser Ipharamitha Eyinhloko Enquma Ukungena Kokushisela Ukuqina kanye Nekhwalithi Yokushisela

In umshini wokushisela we-laser wensimbiizinqubo, amapharamitha anjengombane, isivinini sokushisela, kanye nezilungiselelo zokunyakazisa umzimba ngokuvamile zithola ukunakwa okukhulu. Kodwa-ke, esinye sezici zangempela

ichaza umkhawulo ophezulu wokusebenza kokushisela isikhundla sokugxila kwe-laser.

Ukuthi ukugxila kusethwe kahle yini kunomthelela oqondile ekubuneni kwamandla, ukujula kokungena, ukwakheka kwe-weld, kanye nokuzinza kokusebenza okuphelele kweimishini ye-laser.

Ngakho-ke ukuqonda nokulawula ngokunembile ukugxila kwe-laser kubalulekile ekufinyeleleni ukushisela kwe-laser kwekhwalithi ephezulu.

I. Kuyini Ukugxila Kwe-Laser?

Ngemva kokudlula kulensi yokugxila, umsebe we-laser uhlangana uye endaweni lapho amandla egxile khona kakhulu—leli phuzu laziwa ngokuthi ukugxila kwe-laser.

Eduze kwendawo yokugxila, umsebe we-laser ubonisa izici ezilandelayo:

Usayizi wendawo encane

Ubuningi bamandla obukhulu

Ukusebenza kahle kokumuncwa kwezinto ezibonakalayo okuphezulu kakhulu

Ngenxa yalesi sizathu, ngisho nokushintsha okuncane endaweni yokugxila—ngamamilimitha ambalwa kuphela—kungabangela ushintsho oluphawulekayo ekusebenzeni kokushisela.

II. Izimo Ezintathu Ezijwayelekile Zokugxila kanye Nezimpawu Zazo Zenqubo

Indawo Yokugxila (Zero Defocus)

Uma indawo yokugxila itholakala ngqo ebusweni bezinto zokusebenza noma enkabeni yendawo yokushisela, amandla e-laser agxile kakhulu, okunikeza ikhono lokungena eliqine kakhulu.

Izici:

Ubuningi bamandla obukhulu

Ukujula okukhulu kokungena

Ukuqaliswa kokushisela okusheshayo kanye nokusebenza kahle okuphezulu

Izicelo Ezijwayelekile:

Izinqubo zokushisela ezinezidingo eziphezulu zokungena

Izinto ezijiyile noma izinhlelo zokusebenza ezidinga ukungena okusheshayo okugcwele

Uma kudingeka ukusetshenziswa kwamandla okuphezulu, isikhundla se-zero-focus ngokuvamile siyindlela ekhethwayo.

Ukususa Ukugxila Okubi (Gxila Ngaphezu Komsebenzi)

Uma indawo yokugxila ibekwe ngaphezu kwendawo yokusebenza, umsebe we-laser uqala ukuhlukana ngaphambi kokufinyelela ezintweni ezibonakalayo, okuholela kusayizi webala elikhulu.

Izici:

Amandla asatshalaliswa ngokulinganayo

Ukuqina kwechibi elincibilikisiwe okuthuthukisiwe

Ukujula kokungena okuncishisiwe

Izicelo Ezijwayelekile:

Ukushisela okuqhubekayo kokungena okujulile

Izinqubo ezifuna ukuqina okuphezulu kokushisela kanye nokungaguquguquki komthungo

Ukushisela amapuleti amakhulu ukuze kuncishiswe ukuchitheka kanye nokushintshashintsha kokushisela

Ukugxila okungekuhle kugcizelela ukuzinza kanye nokulawulwa kwenqubo.

Ukususa Ukugxila Okuhle (Gxila Ngaphansi Komsebenzi)

Uma indawo yokugxila ibekwe ngaphansi kwendawo yokusebenza, i-laser yakha indawo enkulu ebusweni, yehlisa ubuningi bamandla endaweni ngayinye.

Izici:

Ukusatshalaliswa kokushisa okufanayo

Ukubukeka kobuso obubushelelezi

Ukujula kokungena okujulile

Izicelo Ezijwayelekile:

Ukushisela ngeshidi elincane

Ukushisela kokuvala okungaphezulu kanye nokushisela kwe-lap

Izicelo ezinezidingo eziphansi zokungena kodwa izidingo eziphezulu ekubukekeni kokushisela

I-defocus enhle ivame ukusetshenziswa ezimweni lapho ikhwalithi yendawo kanye nokulawulwa kwendawo ethinteke ukushisa kubalulekile.

III. Kungani Ukulawula Ukugxila Kubaluleke Kangaka?

Inquma Ngokuqondile Ukungena Kwe-Weld

Uma ukugxila kuseduze nendawo yokushisela eyinhloko, kulapho ubuningi bamandla buphakama khona futhi kulapho ukujula kokungena kukhulu khona.

Kuthinta Ukwakheka Kokushibilika Nokungaguquguquki

Ukuphambuka okukhulu ekugxiliseni kungaholela ebubanzini bokushisela obungalingani kanye nokwakheka komthungo ongazinzile.

Ithonya Ukuzinza Kwenqubo Yokushisela

Izilungiselelo ezifanele zokugxila zisiza ekunciphiseni ukuchitheka, ukunciphisa ukuguquguquka kokushisela, nokuthuthukisa ukuthembeka ekusebenzeni kokushisela okuqhubekayo.

Ithinta Ngokungaqondile Impilo Yesevisi Yemishini

Izimo zokugxila ezingafanele zingabangela ukubonakaliswa kwamandla kanye nama-alamu esistimu, okungathinta kabi ukuzinza kwesikhathi eside kwezingxenye ze-optical kanye nekagesi.

IV. Izincomo Eziwusizo Zokulungisa Ukugxila

Ezinhlelweni zokusebenza zangempela, akukho ukulungiselelwa kokugxila okujwayelekile. Ukulungiswa kokugxila kufanele kunqunywe ngokusekelwe enhlanganisela yezici, okuhlanganisa:

Uhlobo lwezinto (insimbi engagqwali, insimbi yekhabhoni, i-aluminium alloy, njll.)

Ubukhulu bezinto ezibonakalayo

Ukulungiswa kokushisela (ukushisela izinqe, ukushisela imilenze, ukushisela ifillet)

Ukuqhathaniswa kwesivinini sokushisela kanye namandla e-laser

Kunconywa ukunquma indawo efanele yokugxila ngokushisela kwesilingo ngaphambi kokukhiqizwa okusemthethweni nokugcina izilungiselelo ezihambisanayo ngesikhathi sokucubungula inqwaba.

V. Isiphetho

Ukushisela nge-laser kwekhwalithi ephezulu kuncike ekuqondeni okunembile kanye nokulawula ukugxila kwe-laser.

Ukulungiswa kokugxila akuyona nje indaba yokuqondanisa—kuyipharamitha ebalulekile ehlanganisa ukuphathwa kwamandla, indlela yokusebenza, kanye nokuhlangenwe nakho kokushisela.

Kuphela ngokuqonda ukuziphatha kokugxila lapho umuntu engazinza, esebenza kahle, futhi elawulwa ngokugcweleumshini wokushisela we-laser wensimbiimiphumela ingatholakala kuzo zonke izimo ezahlukene zokushisela.
