Muaj ntau ntau hom milling cutters, tab sis los ntawm kev xav ntawm txoj cai milling, lawv tuaj yeem muab faib ua ob pawg: kawg milling thiab circumferential milling, thiab lawv cov cuab yeej raug yog ntsej muag milling cutters thiab cylindrical nto milling cutters. Tus nqi milling suav nrog plaub yam nram qab no, raws li pom hauv daim duab 5-4.
(1) Milling ceev" (m / min) Milling ceev yog hais txog cov linear ceev thaum lub milling cutter tig, thiab cov qauv kev suav yog qhia hauv kab zauv (2-1).
(2) Pub Muaj peb txoj hauv kev los qhia cov khoom noj thaum lub sij hawm milling.
1) Pub ib lub kiv puag ncig f (mm / r) Nws hais txog qhov kev ncua deb ntawm lub workpiece txheeb ze rau lub milling cutter raws li kev coj noj coj ua thaum lub milling cutter txav hauv txhua lub kiv puag ncig.
2) Pub rau ib tus hniav f (mm) Nws yog hais txog qhov kev ncua deb ntawm lub workpiece txheeb ze rau lub milling cutter raws li kev coj noj coj ua thaum lub milling cutter tig lub kaum sab xis ntawm ib tug hniav txhua zaus.
3) Pub ceev (mm / min) Nws yog hais txog qhov kev ncua deb ntawm ib feeb uas lub workpiece txav mus rau lub milling cutter raws li kev coj noj coj ua. Ntawd yog, tus nqi pub ntawm lub rooj milling.
Kev sib raug zoo ntawm peb qhov kev pub: "v=∫n= ∫zm
formula: n -- milling cutter ceev, unit r/min los yog r/s; z-- Tus lej ntawm cov hniav txiav.
Kev pub ntawm txhua tus hniav raug xaiv raws li lub zog ntawm cov hniav txiav, thickness ntawm txheej txheej, thiab lub peev xwm nti. Kev pub rau ib lub kiv puag ncig yog ze ze rau qhov roughness ntawm machined nto, thiab pub ib lub kiv puag ncig yog xaiv rau nplua milling thiab semi-fine milling. Txij li thaum lub ntsiab lus tsa suab thiab pub txav ntawm lub tshuab CNC milling yog tsav los ntawm ob lub cev muaj zog hauv tib qhov kev pabcuam, tsis muaj kev sib txuas sab hauv ntawm lawv. Txawm hais tias qhov pub rau ib tus hniav los yog pub rau ib lub kiv puag ncig ∫x raug xaiv, tus nqi pub v yuav tsum raug xam thaum kawg.
(3) Rov qab muab riam a. (mm) Raws li pom hauv daim duab 5-4, nws yog qhov loj ntawm cov txheej txiav uas ntsuas sib npaug mus rau qhov kev taw qhia ntawm milling cutter axis. Nyob rau hauv cov ntaub ntawv ntawm kawg milling, ", yog qhov tob ntawm txheej txiav; Nyob rau hauv cov ntaub ntawv ntawm circumferential milling,", yog qhov dav ntawm qhov chaw yuav tsum machined.
(4) Sab muab riam a. (mm) Nws yog qhov loj ntawm cov txheej txiav ntsuas perpendicular rau cov kev taw qhia ntawm lub cutter axis thiab cov kev taw qhia ntawm pub. Xaus milling, "yog qhov dav ntawm qhov chaw yuav tsum ua tiav; Thiab thaum milling circumferentially, ". yog qhov tob ntawm txheej txheej.
