This calculator will determine speeds and feed rates for machining operations on mill or lathes. Cutting speeds are usually given in feet or meters per minute and these speeds must be converted to spindle speeds, in revolutions per minute, to operate the machine.
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.
For TiN and TiCN coated tools, increase speed by up to 20% with the feed rate unchanged. For TiAIN coated tools, speeds may be increased by up to 50% with the feed rate unchanged.

Indexed End Mill - Endmills with replaceable cutting edges and steel bodies. These tools allow for higher cutting speeds due to shallow depths of cut and the relative inexpensiveness of inserts. High Feed End Mill - Indexed end mill with an extremely low lead angle that directs most of the cutting force in the downward direction.
When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated.
*The RPM and Chip Load that automatically populates in this calculator are the factory suggested parameters for running the desired tool. Altering the Chip Load or RPM settings in any way without prior written approval from an authorized agent of CGC/Gorilla Mill will void any guarantee or warranty nor will CGC/Gorilla Mill or its agents be liable for any consequential …
Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and ...
