Ụdị usu na-aga n'ihu
Akụkụ dị mkpa nke micromachining anya bụ ịnyefe okpomọkụ na mpaghara nke mkpụrụ nke dị n'akụkụ ihe eji eme ihe.Lasers nwere ike ịrụ ọrụ na ọnọdụ pulsed ma ọ bụ ọnọdụ ebili mmiri na-aga n'ihu.Na ọnọdụ ebili mmiri na-aga n'ihu, mmepụta laser na-adịgide adịgide ka oge na-aga.
Na pulsed mode, na laser mmepụta na-lekwasị na obere pulses.Ngwa laser mode pulsed na-enye pulses na obere oge pulse nwere ike zuru oke maka micromachining nke ihe enyere.Obere oge pulse na-ebelata oke ọkụ na ihe ndị gbara ya gburugburu.Ọkụ laser nwere ike ịdịgasị iche n'ogologo site na milliseconds ruo femtoseconds.
Ike kachasị elu metụtara ogologo oge nke pulse laser, ya mere lasers pulsed nwere ike nweta ọnụ ọgụgụ dị elu karịa ebili mmiri na-aga n'ihu.
Nhazi Laser bụ isi gụnyere mmekọrịta na-eduga na mkpochapụ nke ihe mkpụrụ osisi.Nfefe ike nke na-eme na-adabere na ihe onwunwe na laser.Njirimara Laser nke na-emetụta ihe gụnyere ike kacha elu, obosara usu, na ogologo ikuku ikuku.Ntụle ihe onwunwe bụ ma ọ nwere ike ịnweta ike laser site na usoro thermal na / ma ọ bụ photochemical.
Gịnị kpatara obosara usu ji dị mkpa?
Mbelata Laser dị ọcha na nke ziri ezi.Mkpa ịme obere ngwaọrụ, ngwa ngwa, ọkụ na ọnụ ala dị ala chọrọ lasers iji merie ihe ịma aka ahụ.A na-eji laser pulsed eme ihe maka micromachining nke ọma nke ihe dị iche iche.Ikike imepụta obosara pulse dị iche iche bụ isi ihe maka izi ezi, ntinye, ịdị mma na ọnụ ahịa.
Nanosecond lasers na-eji otu ike nkezi nwere ọnụego mwepụ ihe dị elu yana ya mere mmepụta dị elu karịa picosecond na femtosecond lasers.
Picosecond na femtosecond lasers agbaze ihe iji wepụ ya site na usoro nke vaporizing na agbaze ihe iji chụpụ ya.Nke a na-agbaze nwere ike imetụta nkenke na mma nke machining, dị ka ihe wepụrụ nwere ike na-arapara n'ọnụ na resolidified.
Ọganihu na teknụzụ laser pulsed emeela ka o kwe omume iji micromachining na obere ngwaọrụ, dị ka ngwaọrụ ahụike, na-emebi obere ihe ndị gbara ya gburugburu.Site na ọganihu sayensị ngwa ngwa na ngalaba nke lasers, ọkachamara micromachining laser dị oke egwu.
