Kev tshem tawm cov nti zoo kom tsis txhob khawb lub tshuab ua kom zoo thiab tiv thaiv cov chips los ntawm kev daig ntawm ib feem thiab cov cuab yeej ua ntej kev txiav thib ob, yog li cov chips hlau yuav tsum tau tawg kom ntau li ntau tau kom cov khoom tuaj yeem du thiab ruaj khov. Yog li kuv yuav ua li cas thaum kuv txuas ntxiv nti?cnc machining qhov chaw
Muaj peb txoj kev daws teeb meem:
1. Ua kom qhov tob ntawm kev txiav Ap
2. Nce noj F
3. Siv ib rab riam ntse dua
Kev nce qhov tob ntawm kev txiav thiab nce cov khoom noj yog txhua yam zoo ib yam, uas yog, lub zog ntawm cov hlau filings yog nce, yog li ntawd thaum tib curvature siv, cov ntaub ntawv hlau tuaj yeem tawg.
Daim duab qhia txog qhov xwm txheej uas cov ntaub ntawv hlau tau tawg nyob rau hauv tib lub curvature tom qab qhov tob ntawm kev txiav. Kev nce ntawm cov khoom noj yog nce qhov tob ntawm kev txiav hauv axial kev taw qhia, yog li tib yam vim li cas, kuv yuav tsis kos.
Tau kawg, feem ntau, qhov tob ntawm kev txiav tsis tuaj yeem hloov kho, feem ntau yog kho cov khoom noj (xws li txo qhov nrawm, F tsis hloov, F nce, uas tuaj yeem txhim kho lub cuab yeej lub neej). Txawm li cas los xij, nce qhov pub yuav coj teeb meem sib xws.
Teeb meem 1: Lub txiav quab yuam ua loj, lub zog yuav tsum tau ntawm tag nrho cov txheej txheem yog nce, thiab kev co yuav tshwm sim. Yog tias qhov kev vibration tsis txaus, lwm txoj kev xav tau.
Teeb meem 2: Qhov kawg yog txo. Nyob rau hauv cov ntaub ntawv ntawm tib lub kaum sab xis, qhov nce noj tiav yuav txo qis, yog li them sai sai rau qhov ua tiav ntawm lub workpiece. (Kev sib raug zoo ntawm fillet thiab pub muaj ib tug empirical formula: Ra = (f * f ** 50) / re, qhov loj ntawm pub, lub kaum sab xis ntawm cov cuab yeej me me, qhov ntau dua qhov roughness tus nqi tau txais) Cia kuv tham hais txog kev hloov qhov groove hom. Lub trough yog dab tsi? Qhov tseeb, txhua tus qauv cuab yeej muaj kev taw qhia rau lub chipbreaker nyob rau hauv pem hauv ntej ntawm nws. Piv txwv li, ib qho hauv qab no.
Lub chipbreaker feem ntau saib ntawm lub kaum sab xis thiab cov hniav dav, ib yam li lub kaum sab xis cim hauv "groove profile" saum toj no. Lub kaum sab xis loj dua, qhov loj dua lub kaum sab xis ntawm cov ntaub ntawv hlau. Qhov thinner cov ntaub ntawv hlau, qhov ntau nws yog. Chip tawg, yog li thaum koj txuas ntxiv swarf, nws yog ib qho tsim nyog yuav tsum tau saib lub kaum sab xis pem hauv ntej ntawm cov hniav uas koj siv tam sim no, thiab tom qab ntawd hloov cov hniav ntawm lub kaum sab xis loj dua rau kev ua, cov txheej txheem chip tawg yuav zoo dua.
Kuj tseem muaj qhov dav dav dav, qhov dav dav ntawm cov hniav tsis yog tshwm sim hauv daim duab saum toj no, tab sis nws tau cuam tshuam los ntawm qhov tob ntawm kev txiav, zoo dua, uas yog, qhov tob ntawm cov hniav yog tsim rau kev ua, yog tias koj siv cov hniav tsis tu ncua, ces koj yuav pom Saib lwm cov hniav tuaj yeem txiav me ntsis sib dua. Qee qhov cuam tshuam cov hniav dav raws li qhia hauv qab no.yas ntu
Hauv daim duab saum toj no, cov hniav dav (xws li 0.21) yog cim. Nws yog qhov nkag siab zoo tias qhov me me ntawm qhov dav dav, qhov ntiav nws tuaj yeem txiav. Txawm li cas los xij, qhov tob ntawm kev txiav yuav tsum yog hais txog qhov dav ntawm cov hniav, txwv tsis pub nws tsis yog txiav tab sis sib tsoo. Nyob rau hauv luv luv, nruam scraping, xaiv ib tug me me hniav dav, yuav txiav thinner, thiab lub nti tawg qhov teeb meem yog zoo dua.
Txawm li cas los xij, xaiv lub kaum sab xis loj thiab qhov dav me me yuav ua rau muaj teeb meem. Cov hniav lub zog tsis txaus, thiab cov cuab yeej txaus siab dua. Yog li ntawd, yog hais tias koj xaiv ib tug sharper hniav thiab sim dua, koj muaj peev xwm xaiv ib tug me ntsis softer. Nws tuaj yeem txo qhov taw tes ua ntej (yog tias tsis xav tau kev ua haujlwm zoo).aluminium qhov
