Milling is a process for removing material, which allows obtaining a wide range of surfaces (planes, grooves, inclines, holes, etc.) through the action of a cutting tool with a defined geometry. The most important features of milling are high precision and good surface finish of the finished product. A good milling machine can produce workpieces with tolerances of less than a micron and a “mirror” surface. The main machining parameters of milling are the cutting speed, from which comes the rotation speed of the cutter and the workpiece feed rate.
