Nekuda kwehunhu hwayo hwakanaka hwemuviri nemakemikari, hunhu hwayo hwakanaka hwemakanika, aruminiyamu inoshandiswa zvakanyanya muindasitiri yehafu yeconductor uye microelectronics nedzimwe nzvimbo. Nekuvandudzwa kwezvigadzirwa zvemazuva ano zvemaindasitiri zvinoenda kudivi resimba rakakwirira, chiedza uye kushanda kwepamusoro, nzira yekucheka aruminiyamu nelaser iri kufambira mberiwo kuenda kudivi rekururama, kushanda kwepamusoro uye kuchinjika. Kucheka nelaser kune zvakanakira zvekutsemuka kwakamanikana, nzvimbo diki inokanganiswa nekupisa, kushanda kwepamusoro uye kusamanikidzwa kwemakanika, saka yave nzira yakakosha yekugadzira aruminiyamu nekururama.
Kucheka kwearuminiyamu alloy nelaser kunowanzo shandiswa pakucheka musoro negasi rekubatsira. Maitiro ayo ndeekuti laser inotarisa mukati mearuminiyamu alloy, gasification ine simba guru inonyungudutsa aruminiyamu alloy, uye muviri wegasi rekubatsira une simba guru unobvisa zvinhu zvakanyunguduka. Nzira iyi yekucheka inonyanya kushandisa mhando mbiri dzelaser dzine wavelength inosvika 10640nm ne1064nm, dzose dziri dze infrared wavelength range. Pakucheka kwakanyatsonaka kwearuminiyamu alloy sheet nehukuru hwekucheka hwakarurama hwe micron level, nekuda kwenzvimbo yayo yakakura nenzvimbo yakakura inokanganiswa nekupisa, zviri nyore kugadzira slag inorembera uye micro-cracks pamucheto wekucheka, izvo zvinozopedzisira zvakanganisa kunyatsojeka uye mhedzisiro yekucheka.
Sisitimu yekucheka nelaser uye nzira yealuminium alloy mumuenzaniso inogona kuita kuti workpiece ichekwe nenzira isingabatanidzi nekushandisa pulse width diki uye shortwavelength yelaser beam, uye kudzivirira kurasikirwa nekushushikana kwe contact workpiece inobatwa nenzira yemuchina, pamwe nematambudziko akadai se micro-cracks uye hanging slag inokonzerwa ne hot working mechanism panguva yekucheka. Workpiece inofanira kuchekwa inogadziriswa yakatwasuka nekushandisa fixture chaiyo, uye nzvimbo yekucheka ye workpiece inofanira kuchekwa inotsigirwa kubva kumashure uku nzvimbo ye slit ichichengetwa mumhepo, kuitira kudzivirira cutting effect kuti isakuvadzwe nekushushikana kunokonzerwa nekudonha panguva yekucheka. Mvura inotonhorera inotenderera mumudziyo wetangi remvura inoshandiswa kutonhodza zvikamu zvekucheka kuderedza simba rekupisa pazvinhu zvakapoteredza uye kuwedzera kunaka kwekucheka; Nzira dzakawanda dzekucheka dzinobatanidzwa kuti dziwedzere slit width uye dzivandudze kucheka zvakanaka.
Maitiro ari pamusoro apa ndiwo maitiro ari nani, asi maitiro acho haagumiriswi nemaitiro ari pamusoro apa. Chero shanduko, shanduko, zvitsiviso, musanganiswa uye nyore nyore zvinoitwa pasi pesimba remweya nepfungwa isingatsauki kubva pane zvataurwa pamusoro apa zvinofanirwa kunge zvakafanana nenzira dzekutsiva, izvo zvinosanganisirwa muchikamu chekudzivirira chenzira yekucheka nelaser yealuminium alloy.
