Dab tsi yog CNC milling?
Xav paub ntau ntxiv txog qhov kev tsim khoom siv tswv yim no
CNC milling yog CNC txheej txheem uas suav nrog tshem tawm ib ntu ntawm cov khoom thaiv (lossis workpiece) siv cov cuab yeej tig kom txog rau thaum cov kev cai tsim nyog (lossis feature) tiav. Nws ua rau cov tuam txhab tsim cov khoom nyuaj nrog qhov tseeb thaum ua raws li kev ua siab ntev.
CNC milling tshuab tau txhim kho los ntawm lub sijhawm los tsim cov khoom lag luam uas haum rau cov qauv xav tau ntawm kev lag luam niaj hnub no. CNC milling tshuab yog siv nyob rau hauv ntau yam sectors, xws li aerospace, automotive, robotics, thiab tshuaj, hais ob peb.
Cov ncej no yuav dhau los ntawm qhov nkag thiab tawm ntawm CNC milling. Koj puas xav kawm ntxiv txog cov txheej txheem milling? Dab tsi ntawm kev ua haujlwm milling koj siv? Puas muaj qhov zoo tshaj plaws? Koj twb tuaj txog qhov chaw raug lawm.
CNC milling tshuab yog dab tsi, thiab nws ua haujlwm li cas?
Cia peb mus los ntawm lub hauv paus ntawm milling kom paub qhov zoo ntawm CNC milling tshuab yog dab tsi thiab nws ua haujlwm li cas. Milling yog cov txheej txheem machining uas suav nrog tshem tawm ib ntu ntawm cov khoom thaiv (lossis workpiece) siv lub cuab yeej tig kom txog thaum qhov xav tau kev cai zoo (lossis feature) tiav.
Cov tshuab milling tsoos feem ntau muaj cov chaw txav tau yooj yim (lossis cov khoom siv clamping) uas khaws cov khoom ua haujlwm nyob rau hauv qhov chaw thiab tso cai rau tus neeg teb xov tooj txav mus rau ntau yam kev qhia tawm tsam cov cuab yeej spinning.
CNC milling tshuab, zoo li cov tsoos milling tshuab, tshem tawm cov ntaub ntawv thiab ua cov khoom siv lub rooj txav tau thiab cov cuab yeej spinning. Lawv txawv, txawm li cas los xij, raws li cov txheej txheem kev ua haujlwm no.
Ib txwm milling xav tau tib neeg kev siv cov cuab yeej spinning los tsim cov khoom, thaum CNC milling tshuab siv computer tswj kom ua tiav cov txheej txheem machining.
Cia peb ua tib zoo saib cov txheej txheem milling.
Txheej txheem ntawm CNC milling
Cov txheej txheem sib tsoo yuav raug muab faib ua peb ntu.
Ua ntej, 2D lossis 3D CAD qauv yog tsim.
Siv CAD/CAM software xws li Autodesk Inventor, Fusion 360, thiab SolidWorks, thawj theem hauv CNC milling txheej txheem yog los tsim 3D (los yog 2D) kos duab ntawm cov khoom xav tau. Koj tuaj yeem txiav txim siab qhov ntev thiab kev kam rau siab nrog cov khoos phis tawj-pab tsim (CAD) lossis khoos phis tawj-pab tsim khoom (CAM) thev naus laus zis.
Tus qauv CAD tau hloov mus rau CNC program hauv Phase 2.
Siv CAM software peb pom zoo nyob rau theem 1 kom xa koj cov qauv CAD raws li cov ntaub ntawv sib xws CNC. G-codes yog cov khoos phis tawj uas tuaj yeem hloov pauv los ntawm 3D CAD qauv siv CAM cov cuab yeej.
G code ces ua txhua yam tsim nyog ua, xws li kev txiav txim, cuab yeej txoj kev, tshuab ceev, workpiece txav, thiab lwm yam, txiav.
Theem 3 yog qhov chaw CNC milling tshuab tau teeb tsa thiab cov txheej txheem milling tau ua tiav.
Lub tshuab ua haujlwm tau muab tso rau hauv CNC tshuab ua haujlwm nto, cov cuab yeej txiav txuas nrog lub tshuab CNC spindle, thiab G code uas koj npaj rau theem 2 yog rub tawm.
Txuas ntxiv nrog cov txheej txheem thaum koj ua tiav tag nrho cov theem no. Tag nrho cov haujlwm uas yuav tsum tau hloov lub workpiece rau hauv cov khoom xav tau yuav ua los ntawm lub tshuab milling.
Cov hauv qab no yog peb cov txheej txheem CNC milling nrov.
Nto milling #1
Cov txheej txheem milling feem ntau siv los ua lub dav hlau yog ntsej muag milling. Cov cuab yeej txiav lub axis ntawm kev sib hloov yog perpendicular mus rau saum npoo ntawm lub workpiece yog machined thaum lub sij hawm no machining txheej txheem.
Lub ntsej muag milling kev ua ub no, raws li lub npe qhia, suav nrog kev siv lub ntsej muag milling cutters. Cov cutters no muaj xws li ntau yam hloov cutter hniav, tso cai rau koj los tsim qhov yuav tsum tau nto sai thiab zoo.
Lub ntsej muag milling kuj ua rau lub ntsej muag zoo nkauj dua li peripheral milling. Qhov no yog vim lub fact tias lub ntsej muag milling cutter muab rau ntau meej tswj cov txheej txheem machining thiab tso cai rau tshem tawm cov khoom tsawg dua peripheral milling.
#2 Plane milling
Lub ntsej muag milling, qee zaum hu ua slab milling, yog cov txheej txheem milling los tsim cov chaw tiaj tus, kab rov tav. Cov cuab yeej txiav lub axis yog sib npaug mus rau qhov chaw ua tshuab thaum lub sijhawm machining.
Ib hom tshwj xeeb ntawm cutter (yooj yim milling cutter) nrog cov hniav nyob rau hauv ib puag ncig yog siv nyob rau hauv cov txheej txheem, uas tso cai rau lub tshuab ua hauj lwm txiav.
#3 Lub kaum sab xis ntawm milling
Lub kaum sab xis milling, zoo li lub dav hlau milling, tuaj yeem pab koj ua lub dav hlau. Qhov tsuas yog qhov sib txawv ntawm ob txoj kev ua haujlwm yog txoj kev uas lub tshuab txiav tau teeb tsa.
Lub kaum sab xis milling yog thaum lub cuab yeej lub axis nyob ntawm lub kaum sab xis ntawm lub workpiece nto. Grooves, serrations, thiab chamfering txhua tus tuaj yeem tsim tau li no.
CNC milling muaj ntau qhov zoo.
1. CNC milling tshuab yog ntau meej thiab raug tshaj li ntau txoj kev lag luam tam sim no.
2. Multi-axis CNC tshuab tuaj yeem tsim cov qauv duab geometric nyuaj heev thaum tswj xyuas ntxiv /-0.004mm kam rau ua.
3.A ntau yam khoom siv, nrog rau cov yas, cov khoom sib xyaw, thiab cov hlau, tsim nyog nrog cov tshuab CNC.

CNC tshuab, tsis muaj qhov tsis ntseeg, muaj peev xwm tsim cov geometries nyuaj nrog kev ua haujlwm siab thiab ua raws li kev ua siab ntev. Txawm li cas los xij, zoo li nrog rau lwm cov thev naus laus zis, kev ua tiav ntawm koj txoj haujlwm CNC milling feem ntau yog txiav txim siab los ntawm cov tswv lag luam, cov kws tshaj lij, thiab cov kws ua haujlwm uas ua haujlwm koj lub tshuab CNC milling. Qhov no yog vim li cas nws tseem ceeb heev kom xaiv cov chaw tsim khoom raug rau koj txoj haujlwm.
