Kev Tsim Cov Ntawv Yob Txias (Kev Tsim Cov Ntawv Yob Txias) yog ib qho txheej txheem shaping uas txuas ntxiv dov cov hlau coils los ntawm cov ntawv yob ntau zaus uas tau teeb tsa ua ke los tsim cov profiles ntawm cov duab tshwj xeeb.
(1) Qhov seem ua cov khoom siv sib koom ua ke thiab cov yob hloov pauv. Thaum cov lus qhia khoom hloov pauv, cov yob ntawm qee lub rooj sawv tsis tas yuav hloov pauv, uas tuaj yeem txuag tau qee qhov chaw cia khoom.
(2) Cov ntawv yob ua ke rau cov yob tiaj tus, qhov seem ua qauv ntxhib yog rau sawv ntsug, pawg dov ntsug tau teeb tsa obliquely, qhov ntim ntawm cov yob tig yog me me, thiab qhov hnyav ntawm cov yob ntawm lub tshuab yob ib txwm muaj txo qis ntau dua 1/3, thiab cov qauv khoom siv yog compact dua.
(3) Cov duab ntawm cov yob yog yooj yim, yooj yim rau kev tsim khoom thiab kho, thiab tus nqi rov siv dua ntawm cov yob yog siab.
(4) Qhov kev tsim khoom ruaj khov, lub tshuab dov muaj zog siv tau rau kev tsim cov raj nyias-phab ntsa thiab cov raj phab ntsa tom qab, thiab cov khoom lag luam ntau yam.
Kev tsim cov hlau ntawv txias yog ib txoj kev tshiab thiab thev naus laus zis tshiab uas txuag tau cov khoom siv, txuag hluav taws xob thiab ua haujlwm tau zoo. Siv cov txheej txheem no, tsis yog tsuas yog tuaj yeem tsim cov khoom siv hlau zoo xwb, tab sis kuj tseem tuaj yeem ua kom luv luv lub voj voog kev tsim khoom, txhim kho kev ua haujlwm zoo, thiab yog li txhim kho kev sib tw ua lag luam ntawm cov tuam txhab.
Tau ib nrab xyoo dhau los no, kev dov txias tau hloov zuj zus los ua cov txheej txheem tsim cov hlau ntawv zoo tshaj plaws. 35% ~ 45% ntawm cov hlau strip dov hauv North America yog ua tiav rau hauv cov khoom los ntawm kev khoov txias, uas yog ntau dua li cov hlau siv hauv kev lag luam tsheb.
Nyob rau xyoo tas los no, cov khoom siv hlau txias tau siv dav ua cov khoom tseem ceeb hauv ntau qhov chaw xws li kev tsim kho, kev tsim tsheb, kev tsim nkoj, kev lag luam hluav taws xob thiab kev tsim tshuab. Nws cov khoom muaj xws li cov hlau qhia kev taw qhia, qhov rooj thiab qhov rai thiab lwm yam khoom siv rau qee qhov profile tshwj xeeb tsim rau cov hom phiaj tshwj xeeb, nrog ntau hom. Kev ua tau zoo ntawm ib chav hnyav ntawm cov hlau txias zoo dua li cov khoom siv hlau kub dov, thiab nws muaj qhov tiav ntawm qhov chaw thiab qhov loj me. Yog li ntawd, kev hloov cov hlau kub dov nrog cov hlau txias dov tuaj yeem ua tiav ob qho txiaj ntsig ntawm kev txuag hlau thiab lub zog, yog li tib neeg txaus siab rau cov hlau txias dov. Kev txhim kho cov hlau khoov tau txais kev saib xyuas zoo. Nws yog qhov kev xav tau tas li ntawm cov neeg siv rau ntau yam, kev qhia tshwj xeeb thiab qhov zoo ntawm cov khoom siv hlau txias dov uas txhawb nqa kev txhim kho sai ntawm cov thev naus laus zis txias dov.
