Material Removal Rate. Material Removal Rate (MRR), while not part of the cutting tool's program, is a helpful way to calculate a tool's efficiency. MRR takes into account two very important running parameters: Axial Depth of Cut (ADOC), or the distance a tool engages a workpiece along its centerline, and Radial Depth of Cut (RDOC), or the distance a tool is …

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.

A thread mill is simply an end mill with the thread form and a specific pitch. The machine can be programmed to helically interpolate to the desired diameter. A 1/4-20 thread mill can produce a 1/2-20 or even a 7/8-20 thread making it an excellent choice for uncommon thread sizes or large diameter threads.

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.
