Umgangatho we sheet metal fiber laser umatshini wokusika sichatshazelwa zizinto ezahlukeneyo.Ukuze ufumane umgangatho ofanelekileyo wokusika, ipharamitha nganye yokusika inqunyelwe kuluhlu oluncinci.Okwangoku, sinokuthembela kuphela kwiimvavanyo eziphindaphindiweyo zokufumana iiparitha zokusika ezifanelekileyo phantsi kweemeko ezahlukeneyo.Ukuchitha ixesha kunye nomsebenzi, kwaye awukwazi ukuphendula kwizinto eziphazamisayo kwinkqubo yokusika.Indlela yokufumana ngokukhawuleza iiparitha zokusika ezifanelekileyo phantsi kweemeko ezahlukeneyo zokusika kwaye uzigcine uzinzile ngexesha lokusika kubaluleke kakhulu.Ke ngoko, kuyafuneka ukufunda ukuhlolwa kwe-intanethi kunye nolawulo lwexesha lokwenyani lomgangatho wokusika i-laser.
Isalathisi esibaluleke kakhulu sokusika kwe-laser ephezulu kukuba akukho siphene sokusika kunye nexabiso le-roughness surface yokusika lincinci.Ngoko ke, injongo yokuhlolwa kwexesha langempela kufuneka ikwazi ukuchonga iziphene zokusika kwaye ibone ulwazi olubonisa uburhabaxa bendawo yokusika.Phakathi kwabo, ulwazi loburhabaxa yeyona nto ibalulekileyo kwaye inzima kakhulu.
Ekufunyanisweni koburhabaxa bomhlaba wokusika, isiphumo sophando esibalulekileyo kukufumanisa ukuba i-frequency ephambili ye-pulsation spectrum yesiginali ye-radiation optical kwindawo yokusika ilingana nokuphindaphinda komphetho wokusika kwindawo yokusika, kwaye i-frequency ye-fringe yokusika ihambelana noburhabaxa, ukwenzela ukuba ityhubhu ye-photoelectric ibone Umqondiso we-radiation unxulumene noburhabaxa bomhlaba osikiweyo.Uphawu lwale ndlela kukuba izixhobo zokufumanisa kunye nenkqubo yokucwangcisa izibonakaliso zilula, kwaye ukufumanisa kunye nesantya sokucubungula kukhawuleza.Nangona kunjalo, izinto ezingalunganga zale ndlela zi:
Uphando olongezelelweyo lubonisa ukuba ukuhambelana kweyona ndawo iphambili yesignali yemitha ye-optical kwindawo yokusika kunye ne-fringe frequency kwindawo yokusika inqunyelwe kuluhlu lwezantya ezincinci zokusika.Xa isantya sokusika sikhulu kunesantya esithile sokusika, i-frequency ephambili yesignali iyanyamalala, kwaye uqeqesho oluphezulu alusekho.Naluphi na ulwazi olunxulumene nemigca yokusika.
Ngoko ke, ukuthembela kuphela kwisignali yokukhanya kwemitha yokukhanya kwecala lokusika kunemida enkulu, kwaye kunzima ukufumana ulwazi oluxabisekileyo kwi-roughness yomphezulu womatshini wokusika ngesantya esiqhelekileyo sokusika, ngakumbi ulwazi lobunzima kufuphi nomphetho ophantsi. .Ukusebenzisa i-sensor ebonakalayo ukujonga umda wokusika kunye nemifanekiso ye-spark shower ngexesha elifanayo unokufumana ulwazi olubanzi kunye noluninzi malunga nokusika iziphene kunye nokusika uburhabaxa bomhlaba.Ngokukodwa, i-shower of sparks ejected from the lower end of the slit inobudlelwane obusondeleyo kunye nomgangatho wecala eliphantsi lendawo yokusika, kwaye ngumthombo wolwazi olubalulekileyo lokufumana uburhabaxa bomda ophantsi wendawo yokusika.
I-spectrum ekhutshiweyo kunye ne-frequency engundoqo ye-optical radiation signal phambi kweifayibha laser umatshini wokusika cnczihambelana kuphela nemigca yokusika kwindawo ephezulu yendawo yokusika, kwaye ayibonakalisi imivimbo yokusika kwindawo engezantsi, kwaye ulwazi oluxabisekileyo alukhankanywa.Ngenxa yokuba ngokuqhelekileyo indawo yokusika ihlulwe ibe ngamacandelo aphezulu nangaphantsi, imivimbo ephezulu yokusika icocekile, ilungile, kwaye uburhabaxa buncinci;imivimbo yokusika esezantsi iphazamisekile, uburhabaxa bukhulu, kwaye ngokusondeleyo umgca osezantsi, unzima kakhulu, kwaye uburhabaxa bufikelela kwixabiso eliphezulu kufuphi nomda ophantsi.Umqondiso wokufumanisa ubonisa kuphela imeko yendawo yomgangatho ophezulu, kungekhona umgangatho ophantsi, kunye nolwazi olubi kakhulu lwekhwalithi kufuphi nomda ophantsi.Akukho ngqiqweni kwaye ayithembekanga ukuyisebenzisa njengesiseko sokusika ukuvavanywa komgangatho kunye nokulawula.
