Muaj ntau yam uas tuaj yeem ua rau muaj kev sib txawv ntawm cov khoom tuab thaum lub sij hawm tsim cov txheej txheem ntawm aluminium ntawv ci, xws li: thickness sib txawv los ntawm cov txheej txheem dhau los, mechanical thiab hydraulic thav duab elasticity, yob eccentricity, thermal expansion thiab hnav ntawm yob system, thiab yob bearing clearance. Kev cuam tshuam ntawm tus qauv raug, kev xam qhov yuam kev, lub sijhawm teb, thiab lub sijhawm ua piv txwv ntawm kev tswj hluav taws xob, nrog rau kev cuam tshuam ntawm qhov txo qis, deformation tus nqi, kev ua haujlwm hardening, kev hloov hauv dov ceev thiab nro, cua txias, thiab lwm yam. txheej txheem ntau lawm.
Ua rau kev hloov hauv elastic deformation ntawm lub hauv paus tshuab. Kev hloov pauv ntawm elastic deformation ntawm lub tshuab hauv paus ncaj qha cuam tshuam rau qhov sib txawv ntawm tus nqi, ua rau muaj kev hloov pauv ntawm lub thickness ntawm cov dov daim. Thaum lub sij hawm dov txheej txheem, yog tias qhov sib txawv ntawm qhov yob tuaj yeem hloov kho lub sijhawm kom lub yob qhov sib txawv tuaj yeem ua rau ib nrab lossis tag nrho offset elastic deformation ntawm qhov sawv ntsug los ntawm kev hloov ntawm dov quab yuam, lub thickness sib txawv ntawm cov dov daim yuav raug txo los yog txawm. tshem tawm tag nrho.
Niaj hnub nimno aluminium dov mills yog nruab nrog tsis siv neeg thickness tswj tshuab. Lub hauv paus ntsiab lus yog los tswj qhov sib npaug ntawm qhov sib npaug ntawm cov dov zeb sawv ntsug los ntawm hydraulic siab system los tswj cov yob sib txawv thiab thaum kawg tswj cov thickness ntawm cov sawb. Tsis siv neeg tswj tshuab (xws li AGC systems) feem ntau muab faib ua peb lub tshuab:
(1) Thickness gauge ib feem, kuaj xyuas qhov tseeb thickness ntawm lub sawb. Ntawm qhov chaw tsim khoom, cov neeg ua haujlwm txiav txim siab seb qhov kev tswj xyuas qhov tuab yog qhov txawv txav raws li qhov tseeb ntsuas qhov nkhaus uas pom los ntawm qhov ntsuas thickness yog nyob rau hauv qhov sib txawv ntawm kev tswj ntau yam.
(2) Qhov sib piv thickness thiab kev hloov kho feem ntau yog sib piv qhov tseeb thickness ntawm cov kab nrib pleb nrog cov txheej thickness, tau txais cov thickness sib txawv tus nqi, thiab outputs lub yob sib txawv hloov teeb liab.
(3) Lub yob qhov sib txawv ntawm qhov kev hloov kho feem ntau yog kho qhov sib txawv ntawm qhov sib txawv ntawm lub tog raj kheej hydraulic raws li qhov sib txawv ntawm qhov kev hloov kho lub teeb liab kom tshem tawm lossis txo qhov ntev ntawm lub thickness sib txawv ntawm cov sawb.
Nws yog feem ntau yooj yim los koom nrog qhov ua rau txawv txav thickness sib txawv nrog cov thickness tswj nws tus kheej. Qhov tseeb, qhov ua tau zoo ntawm cov txheej txheem tuab tsis yog tsuas yog cuam tshuam rau nws tus kheej, tab sis kuj nyob ntawm qhov tuab zoo ntawm txhua qhov system ntawm dov zeb, suav nrog cov tuab ntawm cov pob zeb. Yog hais tias lub thickness sib txawv yog tshwm sim los ntawm cov saum toj no Yog hais tias lub hwj chim ntawm yam ntau tshaj qhov yuav tsum tau los ntawm lub thickness tswj system, lub thickness sib txawv yuav ntau tshaj qhov yuav tsum tau.
