### Understanding CNC Cutting Tool Speeds FeedsDestiny Tool

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 = 1600 RPM) for a 1/2" tool. A 1/2 tool is one of the most common sizes of end mill used in the metalcutting industry.

A high speed steel "G" drill is being used prior to reaming a 3/8 hole on a piece of 1095 steel with a brinnel hardness of 300. Calculate the RPM setting to perform the drilling and reaming operations. Cutting Speed = 40 (fpm) Diameter of Cutter = 0.3701 (G drill) Half the speed for reaming would be = 432 / 2 = 216 RPM for reaming.

Oct 02 2017 · Spindle Speed Cap . As shown above the cutter speed (RPM) is defined by the SFM (based on material) and the cutter diameter. With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example a .047" cutter in 6061 aluminum (SFM 1 000) would return a speed of 81 000 RPM.

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.
