1. Kev xaiv thiab kev siv. Plaub txoj hauv qab no yuav tsum tau siv dav hauv kev xaiv cov khoom tshwj xeeb:
1. Txoj kev tsom xam: kev txiav txim siab txiav tawm, uas yog ib txoj hauv kev ntawm kev tsim engineering. Ntawd yog: kev tsom xam thiab kev xaiv kev tshawb fawb raws li lub hom phiaj ua haujlwm ntawm cov khoom siv rooj tog thiab nws cov kev txwv, nrog rau cov khoom ntawm ntau yam ntaub ntawv. Piv txwv li: Ntxiv nrog rau qhov tawv tawv, yuav luag tag nrho lwm yam khoom siv ntawm cov tawv broadleaf khoom ntoo yog siab dua li cov khoom siv dag zog, yog li nws yog qhov tsim nyog rau cov rooj tog zaum txhawb nqa uas tuaj yeem tiv taus qhov hnyav. Txawm li cas los xij, qhov teeb meem loj tshaj plaws ntawm cov khoom ntoo yog o thiab shrinkage, uas yog tsim rau siv raws li cov khoom siv linear. Rau cov rooj tog hauv txee, cov khoom tiaj tus yuav tsum tau, thiab cov khoom ntoo yuav muaj kev phom sij loj. Artificial boards tsuas yog tsim nyog, thiab cov rooj tog zaum hauv txee feem ntau tiv taus cov khoom zoo li qub, thiab cov laug cam tuaj yeem ua tau raws li qhov yuav tsum tau siv. Yog tias npog nrog cov khoom siv ntoo veneers, lub zog tuaj yeem ua kom muaj zog ntxiv thiab cov tsos ntawm cov khoom ntoo tuaj yeem muab tau.
2. Cov ntsiab lus nthuav dav: inductive vim li cas, raws li kev paub dhau los. Ua kom tiav cov kev siv cov ntaub ntawv uas twb muaj lawm, txheeb xyuas lawv cov kev xav tau thiab cov teeb meem uas twb muaj lawm, thiab txhim kho. Feem ntau hais lus, yuav tsum muaj ib qho laj thawj rau nws lub neej, tshwj xeeb tshaj yog kev siv uas tau dhau qhov kev sim ntawm lub sijhawm, uas tsim nyog tau txais kev saib xyuas ntau dua thiab yuav tsum tsis txhob raug tshem tawm yooj yim.
Piv txwv li: Vim li cas Ming-style rooj tog siv ntau cov khoom siv linear? Txawm hais tias muaj kev coj noj coj ua, qhov laj thawj tseem ceeb yog vim li cas peb cov poj koob yawm txwv tau nkag siab txog tej yam ntuj tso ntawm ntoo los ntawm ntau txhiab xyoo ntawm kev paub thiab tau tshawb nrhiav cov txheej txheem los tswj cov kev hloov pauv ntawm cov ntoo vim muaj kev hloov pauv ntawm cov dej noo. Ntawd yog, thaum ua rooj tog nrog cov khoom ntoo, tsis muaj ntau tshaj li tsib txoj hauv qab no los tsim kev txawj ntse:
1) Sim siv cov khoom siv linear. Vim hais tias qhov me me nyob rau hauv transverse grain kev taw qhia, qhov me dua tus nqi ntawm cov ntoo o thiab shrinkage.
2) Sim siv nws rau cov khoom qhib. Thaum cov khoom siv nrog qhov loj dua nyob rau hauv cov lus qhia kev hloov pauv yuav tsum tau siv, sim siv lawv hauv qhov qhib, kom lawv tsis txhob ua rau muaj kev puas tsuaj rau cov qauv vim o thiab shrinkage, thiab lawv yuav tsis yooj yim pom pom. Xws li desktops thiab lwm yam.
3) Qhov kawg yuav tsum raug kaw kom ntau li ntau tau. Kev sib pauv dej noo ntawm sab hauv ntawm ntoo thiab lub ntiaj teb sab nraud feem ntau yog ua los ntawm cov kab ntev ntev, xws li cov hlab ntsha ntawm cov ntoo dav thiab cov tracheids ntawm cov ntoo coniferous.
4) Thaum tsim, cov khoom sib txuas ntawm cov khoom yuav tsum tau khaws cia ntawm tib lub dav hlau ntau li ntau tau. Thaum nws tsis tuaj yeem zam tau, cov txheej txheem yuav tsum tau tso tseg kom tshem tawm lossis ua kom tsis muaj zog tuaj yeem hloov pauv qhov pom.
5) Thaum tsis muaj ib qho ntawm plaub qhov ntsuas saum toj no tuaj yeem siv tau, siv cov kev sib cuag yooj yim. Piv txwv li, yuav tsum muaj kev tshem tawm txaus ntawm cov core board tenons thiab thav duab tenon grooves nyob rau hauv ib tug ncej ntoo qhov rooj rau buffer lub core board thaum nws expands tsis ua puas lub thav duab qauv.
Lwm qhov piv txwv: yog vim li cas cov rooj tog ntawm ib yam khoom yog tsim nyob rau hauv txoj kev no es tsis yog nyob rau hauv lwm cov ntaub ntawv, los yog vim li cas feem ntau ntawm ib yam ntawm cov rooj tog siv cov khoom no. Nws yuav pab tau yog tias koj txheeb xyuas cov khoom thiab ua cov yam ntxwv ntawm cov khoom kom koj thiaj li tau txais txiaj ntsig ntawm nws. Tsis txhob muaj ntau txoj kev taug thaum tsim cov khoom siv.
3. Analogy, zoo sib xws: piv nrog cov khoom yuav tsum tau hloov. Sib piv cov neeg sib tw cov ntaub ntawv ib los ntawm ib qho raws li cov khoom siv ntsuas cov cuab yeej xav tau los ntawm kev siv lub hom phiaj, ua kom lawv lub zog thiab zam lawv qhov tsis muaj zog, thiab saib seb qhov ntsuas qhov tsawg tshaj li qhov zoo tshaj plaws tuaj yeem tsim los ntawm kev siv tswv yim.
Piv txwv li, nyias ntoo veneer dag boards tuaj yeem hloov qhov dav-dav cov khoom ntoo, thiab ntau yam ntaub ntawv tuaj yeem sib xyaw. Lwm qhov piv txwv: Cov ntaub ntawv dab tsi tuaj yeem ua rau cov khoom nkhaus tuaj yeem ua los ntawm? Lawm, muaj cov kav hlau, khoov ntoo, thiab lwm yam kom ua tiav qhov no.
4. Kev coj ua thiab kev tshoov siab: caij nyoog, caij nyoog, kev tshoov siab, khoom induction, kev xav. Cov neeg tsim qauv yuav tsum ua kom paub txog kev tsim qauv hauv lawv lub hlwb, ua tib zoo saib xyuas, xav, thiab khaws cov ntaub ntawv tseem ceeb, thiab pom thiab nkag siab txhua yam hauv lub neej niaj hnub, kev ua haujlwm, thiab kev lom zem. Kev tshoov siab tam sim ntawd feem ntau tshwm sim, thiab tej zaum yuav ua rau muaj kev hloov pauv tseem ceeb.
2. Kev txiav txim siab dav dav
1. Cov yam ntxwv ntawm cov khoom nws tus kheej: Txhua yam khoom muaj nws tus yam ntxwv. Cov yam ntxwv no yuav tsum to taub thaum tsim thiab siv scientifically thiab rationally. Cov yam ntxwv ntawm cov khoom muaj xws li nws lub cev thiab txhua yam ntsuas, cov khoom nto, cov yam ntxwv ua, cov khoom lag luam specifications, thiab lwm yam.
2. Cov ntsiab lus morphological ntawm lub hom phiaj tsim khoom: Piv txwv li, linear, planar, thiab cov khoom siv rooj tog yuav tsum tau ua los ntawm cov khoom tsim nyog rau lawv cov khoom. Lwm cov ntaub ntawv kuj tseem siv tau, tab sis cov nyhuv yuav tsis zoo li qhov zoo tshaj plaws lossis kev lag luam, thiab lwm yam.
3. Cov qauv tsim: Cov qauv sib txawv xav tau cov khoom sib txawv. Piv txwv li, rau lub plhaub rooj tog, yas yog cov khoom siv tsim nyog.
4. Cov yam ntxwv ntawm tus neeg siv: Cov sijhawm siv sib txawv thiab cov neeg siv khoom sib txawv feem ntau muaj qhov sib txawv ntawm cov khoom siv. Piv txwv li, rooj tog hauv cov chaw pej xeem yuav tsum tau siv cov ntaub ntawv uas muaj kev puas tsuaj, thiab cov rooj tog sab nraum zoov yuav tsum xav txog kev siv cov ntaub ntawv uas muaj huab cua tsis zoo; ib txhia neeg nyiam ntoo. Rooj tog, qee cov neeg yuav muab qhov tseem ceeb rau cov rooj tog vaj huam sib luag, thiab lwm yam rau qee yam.
Yog li ntawd, cov khoom siv rooj tog hauv tsev so yuav tsum tau rov qab xav txog cov khoom siv ntawm lub hnub qub tsev so
