Learn Cnc Speeds & Feeds - with rpm & feedrate calculator

Using 250 SFM in the formula above, with a .25" (¼") dia endmill results in an RPM of 3,820. To calculate the feedrate we need to find out the feed per tooth or the feed per rev. Again a good starting point using a good quality endmill would be .002" per tooth. So if we had a 4 flute cutter this would be .008" per REV, (4 X .002").

Milling Machine: Feed Rate Calculator - Handyman Calculator

October 30, 2021. Feed rate refers to the speed at which the cutter is moved across the workpiece. For milling, it is frequently represented in measures of distance per time (usually inches per minute (IPM) or millimetres per minute), with considerations of how many flutes the cutter has subsequently decided what that implies for each flute.

That would be 5.236 feet per revolution x 1240 = 6492 feet at the max RPM of the pulleys. The max blade feet per minute would be 6492 BFPM. If I'm doing this wrong, please let me know. One guy told me that 42 blade feet per second is minimum speed. I have a 20hp, 18" wheels at 5000fpm and would not want anything less.

Cutting generates a lot of heat, making oil based coolant preferable. Many machining spindles require 2000 rpm or more, to provide adequate cutting torque, which means that you have to use relatively small diameter end mills in order to end up with surface speeds this low. If not using coolant, then max surface speed is 50 ft/min. Insulation
