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.
Here you find a collection of good to have milling formulas and definitions that are used when it comes to the milling process, milling cutters, milling techniques and more. Knowing how to calculate correct cutting speed, feed per tooth or metal removal rate is crucial for good results in any milling operation.
