Ntau tswv mold uas muaj kev txhim kho nyuaj tau pom tias kev txhim kho no zoo dua ntau hauv kev tshwm sim kom muaj kev txhim kho lwm yam.

Kev txwv: Sib piv lub zog ntawm khoom nrog rau lub rooj sib cuag

Kev sib raug zoo ntawm qhov chaw hluas tawm thiab qhov tseem ceeb yuav tsum muaj kev txiav txim siab ntau. Yog tias thawj duab nyloj yuav hluas tawm mus rau 2.5% los ntawm kev teeb tsa hir huv thaum kho, tab sis ABS tshuaj hluas tawm tsawg dua 0.6%. Qhov sib txawv no yuav tsum tau sau npe kom meej meej kom paub meej meej tias cov khoom sib cuag zoo.

Tsam: Sib koom tes nrog cov kws tshuaj nqi thiab siv DFM checklists

Kev ua ke nrog rau cov neeg siv khoom tso khoom pab rau cov khaub ncaws tau txais tshawb nrhiav tseem ceeb txog yam li cas cov khoom siv yuav tsim nyog hauv kev them nyiaj. Txhawm rau kev sib tham zoo, cov lus nug zoo li qhov chaw poob, kev sib piv hluv hluv, thiab kev teeb tsa nram qhov suggested mold yuav pom tsha. Thaum muab ntxiv rau cov chawj hmoo zoo tshaj plaws rau kev tsim kho (DFM) checklist, cov chalo yuav tuaj yeem saib xyuas txhua qhov chaw ntawm kev tsim kho. Peb tab tom hais txog cov lus nug zoo li qhov chaw nqaj, kev sau tseg ribs, qhov chaw muab taws, thiab cov lus piav qhia txog tolerance. Cov leej num kuj hais lus zoo dua. Raws li cov tsoom fab tsoom neeg, cov khoom siv uas tau dhau kev saib xyuas DFM yooj yim yuav tsis tas hloov pauv engineering txog 30% ntau dua. Thiab nyob rau ntawm 85 ntawm 100 hnub, cov khoom no yuav tshaj qhov kev saib xyuas nram qhov mold tag nrho tsis tas hloov ntau.
