During contour milling we recommend a lateral infeed of approx. 25 % of the end mill diameter while applying 100 % immersion depth. The immersion depth is conditional to the milling motor, the structure and the stability of the machine. This means a reduction of the values is required, when using a less powerful and / or lighter milling motor.

The optimization of milling process parameters is closely related to the CNC milling accuracy, the improvement of the surface quality and productivity. Milling parameters mainly includes: 1) Milling spindle speed (V): the linear speed of a specific point on the cutting edge in the main motion during milling.
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.
Milling Process cutting Parameter : There are three major cutting parameters to be controlled in any milling operation. These three parameters are cutting, speed, feed rate and depth of cut. These parameters are described below. Cutting Speed Cutting speed of a milling cutter is its peripheral linear speed resulting from operation.
