calculate rpm for end mill

Fablab Feeds and Speeds Calculator

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 foam

PolycarbonateBantam Tools

Polycarbonate can melt under the end mill if too much heat builds up under certain conditions. For example if the settings you re using (speed feed rate depth of cut etc.) cause the material you re cutting to accumulate in the end mill flutes the chips could melt the plastic to the tool ruining your tool and workpiece.

Speeds for Milling Cutters SmithyDetroit Machine Tools

Speeds for Milling Cutters. The speed of milling is the distance in FPM (Feet per minute) in which the circumference of the cutter passes over the work. The spindle RPM necessary to give a desired peripheral . speed depends on the size of the milling cutter. The best speed is being determined by the kind of material being cut and the size and
