Indlela yokuthintela uTshintsho oluBanziswa ngubushushu kwiLaser Machining

Ukusetyenzwa kweLaser kwezixhobo ezibonisa kakhulu-ezifana nobhedu, igolide, kunye ne-aluminium-zibonisa imingeni ekhethekileyo ngenxa ye-thermal conductivity ephezulu. Ubushushu busasazwa ngokukhawuleza kuyo yonke into, ukwandisa indawo echaphazeleke bubushushu (HAZ), ukuguqula iipropathi zoomatshini, kwaye kaninzi kubangele i-edge burrs kunye ne-thermal deformation. Le miba inokuphazamisa ukuchaneka kunye nomgangatho wemveliso ngokubanzi. Nangona kunjalo, amaqhinga amaninzi anokunciphisa ngempumelelo le mingeni ye-thermal.

1. Lungiselela iiParamitha zeLaser

Ukwamkela i-laser ye-pulse emfutshane, efana ne-picosecond okanye i-laser ye-femtosecond, inokunciphisa kakhulu impembelelo yokushisa. Ezi pulses zifutshane kakhulu zisebenza njenge-scalpels ezichanekileyo, zihambisa amandla kwiibhobho ezigxininisiweyo ezithintela ukusasazwa kobushushu. Nangona kunjalo, ukumisela indibaniselwano efanelekileyo yamandla e-laser kunye nesantya sokuskena kufuna uvavanyo olucokisekileyo. Amandla agqithisileyo okanye ukuskena okucothayo kusenokubangela ukwanda kobushushu. Ukulinganisa ngokucophelela iiparitha kuqinisekisa ulawulo olungcono kwinkqubo, ukunciphisa imiphumo engafunekiyo yokushisa.

2. Sebenzisa iindlela ezixhasayo

Ukupholisa kweNdawo: Ukusebenzisa izitshizi zelaser kwimizi-mveliso ukupholisa kwendawo kunokuphelisa ngokukhawuleza ubushushu obuphezu komhlaba kunye nokunciphisa ukusasazeka kobushushu. Kungenjalo, ukupholisa umoya kunika isisombululo esithambileyo nesingenangcoliseko, ngakumbi kwimathiriyeli eethe-ethe.

UkuLungiswa kweGumbi elitywiniweyo: Ukuqhuba ukuchaneka okuphezulu kwe-laser machining kwi-vacuum okanye indawo yegesi ye-inert ngaphakathi kwegumbi elitywiniweyo kunciphisa ukuqhutyelwa kwe-thermal kunye nokuthintela i-oxidation, ngakumbi ukuzinzisa inkqubo.

Unyango lwaPhambi kokuPholisa: Ukuthoba iqondo lobushushu lokuqala lemathiriyeli phambi kokulungiswa kunceda ukufunxa elinye igalelo lobushushu ngaphandle kokugqithisa imida ye-thermal deformation. Obu buchule bunciphisa ukusasazwa kobushushu kwaye buphucule ukuchaneka koomatshini.

Ngokudibanisa ukulungiswa kweparamitha ye-laser kunye neendlela zokupholisa eziphambili kunye nokucubungula, abavelisi banokunciphisa ngokufanelekileyo ukuguqulwa kwe-thermal kwizinto ezibonisa kakhulu. La manyathelo awaphuculi kuphela umgangatho wokusetyenzwa kwe-laser kodwa ukwandisa ixesha elide lezixhobo kunye nokuphucula ukuthembeka kwemveliso.
