Slab Milling V =πDN [in/min], D : cutter diameter w : width of cut
fm : table feed, in/min fm = ftㆍnㆍN, n : # of teeth ft : feed/tooth

End milling의 절삭깊이, 절입깊이
10
End milling Axial depth of cut – 절입 깊이 Radial depth of cut – 절삭 폭
절삭깊이 X 절삭폭 X feed X hps ≤ 기계의 가용 hp up milling - 절삭력 과다 소요, 공구날 흔적 down milling - 바람직, surface finish
