Nto roughness hais txog qhov tsis sib xws ntawm qhov deb me me thiab cov ncov me me thiab cov kwj deg ntawm cov tshuab ua haujlwm. Qhov kev ncua deb (yoj suab) nruab nrab ntawm ob lub nthwv dej lossis ob lub nthwv dej yog qhov me me (hauv qab 1 hli), uas yog qhov yuam kev ntawm micro-geometric. Qhov me me ntawm qhov roughness, qhov smoother ntawm qhov chaw.
Surface roughness feem ntau yog tsim los ntawm cov txheej txheem kev siv thiab lwm yam, xws li kev sib txhuam ntawm cov cuab yeej thiab qhov chaw ntawm lub sijhawm ua haujlwm, cov yas deformation ntawm cov hlau saum npoo av thaum cov chips raug sib cais, thiab cov kev vibration siab nyob rau hauv. cov txheej txheem txheej txheem. Vim qhov sib txawv ntawm kev ua cov txheej txheem thiab cov khoom siv ua haujlwm, lub tshuab ua haujlwm tseem nyob. Muaj qhov sib txawv ntawm qhov tob, qhov ntom ntom, cov duab, thiab kev ntxhib los mos ntawm cov kab.
Txawm hais tias hlau 3D luam ntawv thev naus laus zis nthuav tawm qhov yooj yim hauv kev tsim khoom thiab lub peev xwm los tsim cov khoom nyuaj uas tsis tuaj yeem ua tiav los ntawm cov txheej txheem ib txwm muaj, yog tias daim ntawv thov hlau 3D luam ntawv thev naus laus zis hauv kev tsim khoom tau nthuav dav ntxiv, cov neeg tsim qauv kuj yuav tsum nkag siab txog kev siv cov tshuab thev naus laus zis. txhawm rau txo qhov roughness ntawm cov hlau 3D luam tawm qhov chaw kom tau raws li qhov xav tau tiag tiag.
Qhov roughness ntau npaum li cas cuam tshuam rau hlau 3D tshuab luam ntawv feem ntau nyob ntawm nws daim ntawv thov cheeb tsam. Qee lub sij hawm roughness yuav tsis muaj teeb meem, thiab qee zaum, nws yuav yog qhov zoo. Txawm li cas los xij, feem ntau qhov chaw muaj qee qhov yuav tsum tau ua rau saum npoo roughness.
Thaum machining qhov chaw, cov neeg tsim qauv yuav tsum ua kom muaj kev lag luam tawm los txiav txim siab seb yuav siv cov txheej txheem twg, xws li hlau luam ntawv, casting, lossis hlau hmoov txhaj tshuaj molding.
Lub roughness thiab smoothness ntawm 3D luam ntawv nto muaj feem xyuam rau peb yam:
A. Cov ntaub ntawv luam tawm;
B. Kev tsim kho tsis muaj;
C. Kev taw qhia ntawm qhov chaw;
Nyob rau hauv cov xwm txheej sib txawv, qhov roughness ntawm qhov chaw, cov khoom siv, cov duab, qhov chaw, thiab lwm yam, txhua yam muaj kev cuam tshuam rau saum npoo. Feem ntau hais lus, ntsug yog zoo dua li qhov inclined nto, thiab inclined sab sauv yog zoo dua li qhov chaw qis.
Cov hlau hmoov txhaj tshuaj molding muaj qhov zoo ntawm qhov chaw zoo (zoo li Ra yog 30-50), thaum casting yog qhov ntxhib (Ra ntawm 100 thiab 500 microns). Hlau 3D luam ntawv muaj qhov roughness ntau dua, feem ntau ntawm Ra 250-400 ntxiv rau .
Ntau cov txheej txheem tom qab polishing tuaj yeem ua rau 3D luam tawm qhov ua tau raws li qhov yuav tsum tau ua ntawm roughness. Txawm li cas los xij, cov txheej txheem no tsis tas yuav ua tiav ntawm tus kheej los ntawm cov chaw tsim khoom, thiab thaum yuav tsum tau ua haujlwm tawm, cov nqi ntxiv xws li kev thauj mus los thiab nyiaj siv ua haujlwm tau tshwm sim. Qhov kev pheej hmoo ntawm cov teeb meem zoo kuj nce ntxiv thaum muaj ntau tus neeg koom nrog.
JR muab kev pabcuam ib-nres 3D luam ntawv, suav nrog kev ua haujlwm tom qab, peb muaj peb lub Hoobkas CNC, uas tuaj yeem muab cov txheej txheem hlau hauv qab no.
