Thaum cov txheej txheem ua tau zoo rau cov khoom muaj siab, nws feem ntau tsis tuaj yeem siv ib txheej txheem kom ua tau raws li qhov yuav tsum tau ua, thiab nws yuav tsum tau maj mam ua tiav qhov yuav tsum tau ua kom zoo los ntawm ntau cov txheej txheem. Los xyuas kom meej qhov zoo ntawm CNC machining qhov chaw thiab ua kom tsim nyog siv cov cuab yeej thiab cov neeg ua haujlwm, cov txheej txheem machining feem ntau tuaj yeem muab faib ua plaub theem raws li qhov xwm txheej ntawm cov txheej txheem; Rough machining, semi precision machining, precision machining, thiab xov machining.
CNC workpiece feem ntau muaj ob peb qhov chaw uas yuav tsum tau machined, uas tsis tsuas yog yuav tsum tau precision, tab sis kuj muaj tej yam kev taw qhia yuav tsum tau ntawm txhua nto. Txhawm rau ua kom tau raws li cov kev xav tau no, cov txheej txheem machining ntawm txhua qhov chaw ntawm CNC machining qhov chaw tsis tuaj yeem raug teeb tsa, tab sis yuav tsum ua raws qee cov qauv. Qhov no yog qhov kev xaiv thiab kev hloov pauv ntawm qhov chaw ntsuas qhov ntsuas uas txiav txim siab lub tshuab ua ntu zus, nrog rau cov txheej txheem rau kev npaj qhov ntsuas qhov ntsuas rau cov txheej txheem tom ntej hauv cov txheej txheem dhau los.
Dab tsi yog qhov tseem ceeb ntawm CNC machining sequence
1. Ua ntej ua cov txheej txheem saum npoo, ib qho so yuav tsum tau nqa tawm ntawm qhov ntsuas qhov tseeb kom paub meej qhov tseeb ntawm qhov tseem ceeb.
2. Tom qab lub precision siv machining tiav lawm, ntxhib machining, semi precision machining, thiab precision machining yuav tsum tau nqa tawm ntawm qhov chaw nrog siab precision. Nto nrog tshwj xeeb siab precision yuav tsum tau ua tiav.
3. Qhov saum npoo uas siv los ua qhov tseeb yuav tsum tau ua tiav thaum pib ntawm CNC machining txheej txheem, raws li nws yog siv rau qhov chaw thaum ua lwm yam nto hauv cov txheej txheem tom ntej. Ntawd yog, 'benchmark ua ntej, ces lwm tus'.
4. Thaum machining precision siv qhov chaw, coarse reference positioning yuav tsum tau. Nyob rau hauv ib thooj, me me batch ntau lawm, thiab txawm batch ntau lawm, rau castings thiab forgings nrog complex duab los yog loj teev, raws li zoo raws li blanks nrog loj scale yuam kev, lub cim txheej txheem yuav tsum tau teem ua ntej lub tshuab ua txheej txheem los muab ib tug alignment benchmark rau precision machining.
