Ubuchwepheshe be-Micromachining bungasetshenziswa ezinhlobonhlobo zezinto.Lokhu kufaka phakathi ama-polymers, izinsimbi, ama-alloys nezinye izinto eziqinile.Ubuchwepheshe be-Micromachining bungenziwa ngokunemba bufinyelele engxenyeni eyinkulungwane yemilimitha, busize ukwenza ukukhiqizwa kwezingxenye ezincane kusebenze kahle futhi kube ngokoqobo.Okwaziwa nangokuthi ubunjiniyela bemishini yesikali esincane (inqubo ye-M4), i-micromachining ikhiqiza imikhiqizo ngayinye ngayinye, isiza ukusungula ukuvumelana kwe-dimensional phakathi kwezingxenye.
1. Buyini ubuchwepheshe be-micromachining
Okwaziwa nangokuthi ukwenziwa kwemishini emincane yezingxenye ezincane, ukwenziwa kwemishini emincane kuyinqubo yokukhiqiza esebenzisa amathuluzi amancane anomshini anemiphetho yokusika echazwe ngokwejometri ukuze kwakhe izingxenye ezincane kakhulu ukuze kuncishiswe izinto zokwakha imikhiqizo noma izici ezinobukhulu obuthile okungenani ebangeni le-micron.Amathuluzi asetshenziselwa i-micromachining angase abe mancane njengo-0.001 amayintshi ububanzi.
2. yiziphi amasu machining micro
Izindlela zokukhiqiza zendabuko zifaka phakathi ukuphenduka okuvamile, ukugaya, ukwakhiwa, ukusakaza, njll. Kodwa-ke, ngokuzalwa nokuthuthukiswa kwamasekhethi ahlanganisiwe, ubuchwepheshe obusha bavela futhi bathuthukiswa ngasekupheleni kwawo-1990: ubuchwepheshe be-micromachining.Ku-micromachining, izinhlayiya noma imisebe enamandla athile, njengemishayo ye-electron, imishayo ye-ion kanye nemishayo yokukhanya, kuvame ukusetshenziselwa ukusebenzisana nezindawo eziqinile futhi kukhiqizwe izinguquko zomzimba namakhemikhali ukuze kuzuzwe injongo oyifunayo.
Ubuchwepheshe be-Micromachining yinqubo eguquguqukayo kakhulu evumela ukukhiqizwa kwezingxenye ezincane ezinobunjwa obuyinkimbinkimbi.Ngaphezu kwalokho, ingasetshenziswa ezinhlobonhlobo zezinto zokwakha.Ukuzivumelanisa nezimo kuyenza ifaneleke ngokukhethekile ukugijima kombono kuya ku-prototype, ukwakhiwa kwezakhiwo eziyinkimbinkimbi ze-3D kanye nokwakheka nokuthuthukiswa komkhiqizo ophindaphindwayo.
3. ubuchwepheshe be-laser micromachining, obunamandla ngaphezu komcabango wakho
Lezi zimbobo emkhiqizweni zinezici zosayizi omncane, ubuningi obujulile kanye nezidingo zokunemba kokucubungula okuphezulu.Ngokuqina kwayo okuphezulu, ukuqondisa okuhle nokuhambisana, ubuchwepheshe be-laser micromachining, ngokusebenzisa uhlelo oluthile lokubona, bungagxilisa ugongolo lwe-laser endaweni yama-microns ambalwa ububanzi, futhi ukuminyana kwamandla kugxile kakhulu kakhulu, izinto zizofinyelela ngokushesha ekuncibilikeni. iphuzu futhi lincibilike libe yimpahla encibilikisiwe, ngokuqhubeka kwesenzo se-laser, into encibilikisiwe iqala ukuhwamuka, ikhiqize Njengoba i-laser iqhubeka nokusebenza, into encibilikisiwe iqala ukuhwamuka, ikhiqize ungqimba oluhle lomhwamuko, lwakha ukuhlangana kwezigaba ezintathu ukuba khona komhwamuko, okuqinile noketshezi.
Ngalesi sikhathi, ukuncibilika kukhishwa ngokuzenzakalelayo ngenxa yokucindezela komhwamuko, okwenza ukubonakala kokuqala komgodi.Njengoba isikhathi sokushiswa kwemisebe ye-laser sikhula, ukujula nobubanzi bembobo encane kuyanda kuze kube yilapho ukushiswa kwe-laser kuqedwa ngokuphelele, izinto ezincibilikisiwe ezingakaphazwanga zizoqina futhi zenze isendlalelo sokuphindaphinda, ngaleyo ndlela kufezwe inhloso yokungacutshungulwa kwe-laser. .
Njengoba imakethe yemikhiqizo enembayo ephezulu kanye nezingxenye zemishini yesidingo sokucutshungulwa okuncane siya ngokuya sinamandla, futhi ukuthuthukiswa kobuchwepheshe bokucubungula i-laser kuya ngokuya kuvuthiwe, ubuchwepheshe bokucutshungulwa kwe-laser micro kanye nezinzuzo zabo eziphambili zokucubungula, ukusebenza kahle okuphezulu kokucubungula futhi kungacutshungulwa. ukukhawulelwa kwezinto ezibonakalayo kuncane, akukho monakalo obonakalayo kanye nokusetshenziswa kokuguquguquka okuhlakaniphile nezinye izinzuzo, ngokunemba okuphezulu ukucubungula imikhiqizo kuzosetshenziswa kabanzi.
