Cov khoom nkhaus thiab cov cuab yeej nkhaus cuab yeej yog hom ua haujlwm uas haum rau cov chaw ua haujlwm. Hauv kev lag luam, cov khoom nkhaus kuj tseem siv dav, xws li cov tshuab cua tshuab, cov kiv cua nkoj, cov khoom lag luam nrog cov cylindrical conical nto, thiab lwm yam. Thaum ua qhov chaw nkhaus, feem ntau yog siv milling. Yam twg yuav tsum tau them nyiaj mloog rau thaum milling qhov nkhaus?
Kev ua cov ntu nkhaus kuj ua raws txoj cai ntawm CNC machining chaw, uas yog, kev ua haujlwm ntxhib (ntxhib) -semi-xov-ua tiav-ua tiav-ua tiav. Vim tias daim ntawv dawb-nkhaus thiab qhov chaw tsis tuaj yeem hais qhia meej los ntawm cov duab kos duab thiab cov duab siv tshuab, nws tau dhau los ua qhov teeb meem tseem ceeb yuav tsum tau daws nyob rau theem ntxhib ntawm qhov chaw ua haujlwm.
Ntxhib
Txhawm rau txhawm rau txhim kho qhov ua kom zoo dua qub thaum qhov ntxhib ntawm qhov nkhaus ntu ntu tau ua tiav ua ntej, raws li cov npoo tau muab los ntawm cov txheej txheem nkhaus, qhov kawg zeb tuaj yeem siv rau milling txheej los ntawm txheej raws li txheej txheej txheej. Tom qab ntxhib milling, cov duab ntawm qhov nkhaus yuav tshwm hierarchical faib, thiab qhov siab ntawm cov kauj ruam nyob ntawm qhov ntxhib milling raug. Thaum lub sijhawm ua haujlwm tsis zoo, vim yog kev siv lub tshuab ua haujlwm loj thiab txiav nyiaj, ntau qhov txiav cov cua sov tau tsim thaum lub sijhawm txiav, uas yog ib qho yooj yim ua rau cov cuab yeej hnav sai. Lub sijhawm no, qhov ntsuas kub ntawm thaj chaw txiav yuav tsum qis dua, thiab cov kua txiav yuav tsum tau siv nyob rau theem no. Lubrication thiab txias txias.
Semi-ntxhib
Semi-roughing yog qhov tsis tseem ceeb. Nws yog ib theem tseem ceeb los ntawm kev ntxhib kom tiav. Nws lub hom phiaj yog txhawm rau tshem tawm qhov seem ntxiv hauv cov kauj ruam ntxhib. Kev ua tiav ib nrab milling yuav tsum tau nqa nrog lub pob kawg milling cutter, thiab nws cov kab sib nrug thiab cov kauj ruam nyob deb yuav tsum loj dua qhov ua tiav milling. Nws yuav tsum tau sau tseg tias kev ua tiav ib nrab milling yuav tsum tawm ntawm kev ua haujlwm ntawm kwv yees li 0.5 hli rau cov txheej txheem ua tiav tom ntej. Tom qab cov txheej txheem no, cov duab ntawm cov txheej txheem ua tiav yog ze rau qhov theoretical curved nto.
Ua tiav
Kev ua tiav yog txheej txheem ntawm kev ua tiav zaum kawg ntawm qhov kev xav ntawm qhov chaw nkhaus. Pob-kawg milling cutters yog thawj qhov kev xaiv rau cov cuab yeej ua tiav, thiab kab txiav feem ntau yog siv. Kev mloog yuav tsum tau them rau qhov xaiv qhov hloov pauv thiab txiav txim siab ntawm kev pub ceev thaum lub sijhawm ua haujlwm. Rau qhov uas muaj qhov qhib tau zoo dua, qhov hloov pauv yuav tsum raug xaiv sab nraum lub rooj nkhaus, uas yog hais, qhov nkhaus yuav tsum tsim nyog nthuav tawm sab nraud thaum lub sijhawm ua haujlwm.
Rau qhov tsis zoo qhib, txij li kev txiav nrawm yuav hloov thaum lub sijhawm txheej txheem, nws yooj yim tawm cov cuab yeej cim rau ntawm qhov chaw ua haujlwm thiab qhov thaiv qhov tshwm sim tshwm sim los ntawm kev ncua thiab kev co, yog li txheej txheem txheej txheem tam sim no tsis muaj feem siv. Lub taw tes tig yuav tsum tau xaiv ntawm txoj haujlwm kom deb ntawm qhov thaiv qhov chaw, thiab qhov pub ceev yuav tsum raug txo thaum tig rov qab. Cov kab sib tshuam ntawm cov kab nkhaus thiab cov thaiv qhov chaw yuav tsum tau ua tiav cais los ntawm txoj hauv kev tshem tawm cov hauv paus, txhawm rau kom ntseeg tau tias muaj kev sib txuas zoo ntawm cov txheej txheem nkhaus thiab thaiv cov nplaim thiab zam cov cuab yeej pom tseeb.
