Milling Worksheet-SHOW ALL WORK
A milling operation is to be performed at 100 sfpm at .005 ipt. A 500" diameter, 4 flute HSs
end mill is to be used. The operation is a slot .100" deep across the diagonal of a rectangular part
4 inches wide and 6 inches long. The material is 4140 medium carbon steel (BHN-250). Use a
specific HP of 1.2 HP/in/min. Calculate:
RPM
feed (ipm)
feed (ipr)
Length of cut
Cut time
