Milling txiav ceev yog hais txog qhov ceev ceev ntawm ib qho chaw xaiv ntawm lub cutter txheeb ze rau qhov sib thooj ntawm lub workpiece.
Vc=πDN/1000
Vc: txiav ceev (m / min)
N: Cutter rotational ceev (r/min)
D: Milling cutter txoj kab uas hla (mm)
Kev txiav ceev yog cuam tshuam los ntawm cov khoom xws li cov khoom siv txiav, cov khoom siv ua haujlwm, lub rigidity ntawm cov cuab yeej siv tshuab, thiab txiav cov kua. Cov kev txiav qis qis feem ntau yog siv los ua cov hlau tawv lossis tawv tawv- txheej txheem hu ua hnyav- lub luag haujlwm txiav - txhawm rau txo cov txiav hnav thiab ua kom lub neej ntev. Kev txiav nrawm dua feem ntau yog siv los ua cov ntaub ntawv softer kom ua tiav qhov zoo tshaj plaws. Kev txiav ceev kuj tseem tuaj yeem ua haujlwm thaum siv me me - txoj kab uas hla cutters rau micro-machining kev khiav hauj lwm ntawm cov khoom nkig los yog cov khoom precision. Piv txwv li, thaum siv high -ceev steel (HSS) cutters, txiav ceev yog 91-244 m / min rau txhuas thiab 20-40 m / min rau bronze.
