Contour milling thiab pob zeb nce toj milling
Daim duab 6-26a yog ib qho yooj yim schematic ntawm cov khoom nto milling. Qhov saum npoo tsis yog qhov nyuaj heev, tab sis lawv tuaj yeem xaiv los ntawm ntau txoj hauv kev. Yog tias koj siv cov cuab yeej siv tshuab nrog ntau tshaj peb-axis txuas, koj tuaj yeem xaiv thaj chaw dav dua, thiab koj tuaj yeem siv qhov kwv yees ntawm txoj kev contour nrog me me inclination raws li qhia hauv daim duab 6-26b (cov kab contour yog thawj zaug siv rau daim ntawv qhia hauv av, thiab lub tswv yim yog qiv los ntawm peb-dimensional deg milling), tab sis yog tias nws tsuas yog CNC tshuab cuab yeej nrog ob-axis txuas, feem ntau tsuas muaj ob txoj hauv kev milling: contour milling (saib cov kab liab liab. hauv daim duab 6-27a) thiab pob zeb nce toj milling (saib cov kab liab liab hauv daim duab 6-27b).
Contour milling yog kho cov duab ntawm peb-dimensional nto raws li ib tug peb-dimensional landform, thiab cov milling cutter mills raws kab contour ntawm "landform". Pob zeb nce toj milling kuj kho cov duab ntawm peb-dimensional nto raws li ib tug peb-dimensional landform, thiab txiav raws li nto nyob rau hauv cov kev taw qhia perpendicular mus rau lub contour kab nrog ib tug trajectory zoo li cov pob zeb climber. Nyob rau hauv cov txheej txheem ntawm pob zeb nce toj thiab milling, ob qho tib si txoj kev nqes hav nqes hav (saib daim duab 6-28) thiab lub ces kaum (saib xiav xub hauv daim duab 6-27) muaj teeb meem. Txoj kab nqes nqes qis yog yooj yim heev los ua rau lub pob qhov ntswg txiav ntug ntawm lub pob qhov ntswg milling cutter kom ze rau ntawm lub chipping ntug ntawm lub circumferential txiav ntug, vim hais tias lub txiav ua hauj lwm lub kaum sab xis ntawm lub cuab tam ntawm no tau hloov zoo heev piv nrog lub zoo li qub lub kaum sab xis. , axial ua hauj lwm rake lub kaum sab xis ntawm lub milling cutter yuav loj heev, thiab axial ua hauj lwm rear lub kaum sab xis yog heev yuav ua tau ib tug tsis zoo tus nqi, los yog txawm ib tug me me nqi tsis zoo, thiab qhov teeb meem no yog ib qho yooj yim mus ua chipping. Yog li ntawd, tus nqi pub yuav tsum tau txo rau downwards nqes hav. Daim duab 6-30 qhia txog kev sib raug zoo ntawm kev pub rau ib tus hniav thiab kev coj noj coj ua ntawm pob zeb nce toj milling.
Cov ces kaum ntawm lub pob zeb nce toj yog qhov ua rau chipping ntawm qhov chaw ntawm lub pob qhov ntswg milling cutter (saib daim duab 6-29). Cov ces kaum no nquag mus gouging, tshwj xeeb tshaj yog nyob rau hauv high speeds.
Nws raug nquahu kom siv lub tshuab peb-dimensional ntawm lub tshuab ob-axis, siv contour milling, thiab siv txoj kev nce milling. Nyob rau tib lub sijhawm, ntawm cov ces kaum ntawm cov kab contour, trochoidal milling, sheet milling lossis dynamic milling txoj kev piav qhia hauv qab no yog siv. Tom qab txhua qhov contour milling tiav lawm, ib qho tshiab contour machining yog pib hauv daim ntawv arc.
Ntawm cov cav tov nrog peb los yog ntau tshaj ib txhij axes, nws raug nquahu kom siv ib qho kev kwv yees contour txoj kev nrog me me inclination, thiab nws tseem pom zoo kom siv txoj kev nce milling. Qhov no ua rau tsawg plunges thiab smoother txiav.
