Izinga le sheet metal fibre laser cutting umshini ithonywa yizici ezihlukahlukene.Ukuze uthole ikhwalithi efanelekile yokusika, ipharamitha ngayinye yokusika inqunyelwe ebangeni elincane.Okwamanje, singathembela kuphela ekuhlolweni okuphindaphindiwe ukuze sithole imingcele yokusika enengqondo ngaphansi kwezimo ezihlukene.Kudla isikhathi futhi kukhandla, futhi engakwazi ukuphendula ezicini eziphazamisayo ohlelweni lokusika.Indlela yokuthola ngokushesha imingcele yokusika efanelekile ngaphansi kwezimo ezihlukene zokusika futhi uzigcine uzinzile ngesikhathi sokusika kubaluleke kakhulu.Ngakho-ke, kuyadingeka ukutadisha ukuhlolwa kwe-inthanethi kanye nokulawula isikhathi sangempela sekhwalithi yokusika i-laser.
Inkomba ebaluleke kakhulu yekhwalithi ephezulu yokusika i-laser ukuthi asikho isici sokusika futhi inani lokumaketha kwendawo yokusika lincane.Ngakho-ke, okuhlosiwe kokuhlolwa kwesikhathi sangempela kufanele kukwazi ukuhlonza amaphutha okusika futhi kubone ulwazi olubonisa ukukhahlamezeka kwendawo yokusika.Phakathi kwazo, ulwazi olumahhadlahhadla lubaluleke kakhulu futhi lunzima kakhulu.
Ekuboneni ukukhahlamezeka kwendawo yokusika, umphumela obalulekile wocwaningo ukuthola ukuthi imvamisa eyinhloko ye-pulsation spectrum yesiginali yemisebe ye-optical ngaphambili yokusika ilingana nemvamisa ye-fringe yokusika yendawo yokusika, futhi imvamisa ye-fringe yokusika ihlobene nokuqina, ukuze ithubhu ye-photoelectric ithole Isignali yemisebe ihlobene nokuqina kwendawo enqunyiwe.Isici sale ndlela ukuthi imishini yokuthola kanye nesistimu yokucubungula isignali kulula, futhi ukutholwa kanye nesivinini sokucubungula kuyashesha.Nokho, imibi ngale ndlela yilezi:
Ucwaningo olwengeziwe lubonisa ukuthi ukungaguquguquki kwemvamisa eyinhloko yesiginali yemisebe ye-optical ngaphambili kokusika kanye nemvamisa ye-fringe endaweni yokusika kukhawulelwe ebangeni lezivinini zokusika ezincane.Lapho isivinini sokusika sikhulu kunesivinini esithile sokusika, imvamisa eyinhloko yesiginali iyanyamalala, futhi ukuqeqeshwa okuphezulu akusatholakali.Noma yiluphi ulwazi oluhlobene nemigqa yokusika.
Ngakho-ke, ukuthembela kuphela esignali yokukhanya emisebeni yokukhanya ye-front cutting kunemikhawulo emikhulu, futhi kunzima ukuthola ulwazi olubalulekile ebusweni bomshini wokusika ngesivinini esivamile sokusika, ikakhulukazi ulwazi lwama-roughness eduze konqenqema oluphansi. .Ukusebenzisa inzwa yokubukwayo ukuqapha unqenqema kanye nezithombe zeshawa yenhlansi ngesikhathi esifanayo kungathola ulwazi olubanzi noluningi mayelana nokusika amaphutha kanye nokusika ama-roughness ebusweni.Ikakhulukazi, ukugeza kwezinhlansi ezikhishwe ekugcineni okuphansi kwe-slit kunobudlelwane obuseduze nekhwalithi yomkhawulo ophansi wendawo yokusika, futhi kuwumthombo wolwazi obalulekile wokuthola ubulukhuni bonqenqema oluphansi lwendawo yokusika.
I-spectrum ekhishiwe kanye nemvamisa eyinhloko yesiginali yemisebe yokubona ngaphambili kwefibre laser cutting machine cnczihlobene kuphela nemigqa yokusika engxenyeni engenhla yendawo yokusika, futhi ayibonisi imigqa yokusika engxenyeni engezansi, futhi ulwazi olubaluleke kakhulu alukhulunywa.Ngoba ngokuvamile indawo yokusika ihlukaniswe izingxenye ezingaphezulu nezingezansi, imigqa yokusika engenhla icocekile, ilungile, futhi ubulukhuni buncane;imigqa yokusika ephansi iphazamisekile, ukuhlukumeza kukhulu, futhi umkhawulo ophansi useduze, unzima kakhulu, futhi ukuqina kufinyelela inani eliphakeme eduze konqenqema oluphansi.Isignali yokuthola ibonisa kuphela isimo sekhwalithi engcono kakhulu, hhayi ikhwalithi ephansi, kanye nolwazi lwekhwalithi embi kakhulu eduze konqenqema oluphansi.Akunangqondo futhi akuthembeki ukuyisebenzisa njengesisekelo sokusika ukuhlolwa nokulawula ikhwalithi.
