control milling feedrate
Milling Speed and Feed Calculator
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 cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

Feeds & speeds
The whole "feeds & speeds" topic is arguably the most daunting part of learning CNC. " Feeds" is feedrate, on some CNCs with a fixed tool and moving plate this is the speed at which the material is fed into the cutter, on a Shapeoko this is the speed of the gantry pushing the cutter into the material. " Speeds" is the rotation speed of the endmill, i.e. RPM value.
