Calculating RPM For Milling • RPM = CS x 4/D • Where RPM = Spindle speed (in revolutions per minute). • CS = cutting speed of milling cutter (in SFPM) • D = diameter of milling cutter (in inches)
Calculating Feed Rate For Milling • • • Feed Rate is expressed in IPM = CPT x N x RPM IPM = Feed rate in inches per minute. CPT = Chip per tooth N = Number of teeth of the milling cutter
Calculate Feed Rate For Milling Given The Following: • • CS = 300 D = 0. 5” CPT = 0. 005 N=2
Answer • The first step is to calculate the spindle speed before the feed rate can be calculated. • RPM = CS X 4/D = 300 x 4/0. 5 = 2, 400 • The second step is to calculate the feed rate. • IPM = CPT x N x RPM • = 0. 005 x 2, 400 • = 24 IPM (Inches Per Minute)
