    The milling processdefinitions Cutting speed v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters

    Apr 02 2011 · so far im going ok with the lathe but im having trouble working out cutting speeds for the mill. i have looked at a few RPM/cutting speed calculators on the net but they all confuse me. the mill i have is a SIEG U2. it came with an end mill/slot drill set ranging from 412mm. i want to machine some slots through mild steel plate.

    Since the cutting speed for mild steel is 90 the RPM for a 3/8" high-speed two flute end mill is. RPM = CS x 4 / D = 90 x 4 / (3/8) = 360 /.375 = 960 RPM To calculate the feed rate we will select .002 inches per tooth. IPM = F x N x RPM = .002 x 2 x 960 = 3.84 IPM Machine Feed

    Each end mill has flutes on its cutting head that carry the removed material away from the workpiece to prevent damage to the end mill or workpiece. Ball end mills create a round-bottomed groove in a workpiece. Square end mills cut a flat-bottomed groove with 90° inside corners. Corner-chamfer and corner-radius end mills make a flat-bottomed

    1" Diameter end mill RPM/ SFM = constant 800 / 200 = 4 or to put it another way SFM X 4 = RPM. What the machinists realized is that SFM is a formula based upon a 1" diameter. They realized that 4 was a constant so they multiplied the SFM constant by 4 to get the RPM for a 1" tool (200 SFM X 4 = 800 RPM) and multiplied the SFM by 8 (200 SFM X 8
