Cov khoom ntoo yog dav siv nyob rau hauv cov rooj tog, lub tsev décor, thiab txhua yam txhua yam vim lawv cov khoom siv ntuj thiab ib puag ncig zoo. Txawm li cas los xij, ntoo lub zog kuj tseem muaj ntau txoj kev sib tw hauv kev tswj hwm txhua theem, los ntawm cov khoom siv raw rau cov khoom tiav khoom.
Kev ntsuas raw yog qhov tseem ceeb. High - Cov ntoo zoo yuav tsum tau ua kom tau raws li cov hmoov nplej, kab {{dawb, thiab lwj}} dawb. Cov khoom siv ntoo sib txawv yuav tsum muaj cov tsiaj tshwj xeeb. Piv txwv li, hardwoods (xws li oak thiab walnut) feem ntau siv nyob rau hauv rooj tog, thaum cov menyuam cov khoom lag luam zoo li cov khoom muag qis qis {6} all all all soft soft້ອນ (xws li ntoo thuv). Tus xa khoom tsim nyog thiab ua kom qhuav yog ntoo kom qhuav yog qhov sib luag. Cov ntsiab lus noo noo tuaj yeem ua rau excompation tom ntej thiab tawg, yog li nws yog feem ntau tswj tsis pub dhau 8% mus rau 12% (nyob ntawm thaj av huab cua).
Cov txheej txheem tswj lub sijhawm ua haujlwm ncaj qha ncaj qha cuam tshuam qhov kawg zoo. Machining yuav tsum xyuas kom meej qhov tseeb ntawm qhov tseeb thiab nto smoothness, tshwj xeeb tshaj yog nyob rau hauv mortise thiab tenon pob qij txha lossis cov pob qij txha. Kev kho cov npoo av (xws li xim thiab ntoo wax) yuav tsum tau ntsib cov qauv ib puag ncig kom tsis txhob muaj cov tshuaj muaj teeb meem ntau dhau ntawm formaldehyde. Rau cov khoom lag luam ntoo los yog laminated ntoo, lub durability thiab ib puag ncig cov phooj ywg ntawm cov nplaum yuav tsum tau kuaj kev tshaj lij.
Kev kuaj cov khoom tiav yog cov kauj ruam kawg hauv kev ua kom zoo. Kev kuaj cov cuab yeej ib txwm muaj xws li load - qhov sib txawv ntawm cov khoom siv (xws li cov ntawv pov thawj ib puag ncig (xws li cov ntawv pov thawj ua haujlwm. Rau siab -}}}}}} kev ntsuas kub (simulating kub thiab vaum siv cov kev sim simulation kuj yuav tsum tau ua.
Ib qho ntxiv, cov neeg ua haujlwm cob qhia thiab cov txheej txheem qauv yog qhov tseem ceeb. Cov neeg ua haujlwm yuav tsum paub nrog cov yam ntxwv ntawm cov ntoo thiab cov khoom siv hluav taws xob. Cov tuam txhab yuav tsum tsim kom muaj tag nrho {2} txheej txheem traceazeability system los yog cov khoom nyoos kom ntseeg tau tias muaj teeb meem tau qhia sai.
Kev tswj cov khoom ntoo tsis zoo yog tsis yog qhov yuav tsum ua kom nruj ntawm ib theem; Nws yog cov txheej txheem ua haujlwm nyob thoob plaws hauv kev muab khoom thiab cov saw ntau lawm. Tsuas yog los ntawm kev sib txuas ua ke nrog kev sim cov cuab yeej niaj hnub tuaj yeem txhim khu kev qha cov khoom zoo yog ua tiav thaum khaws cov ntoo zoo nkauj ntawm ntoo.
