CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D, 3D, 4axis, and 5axis. However, the term 2D is a bit misleading since this toolpath uses the Zaxis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.

The second one is for calculating the surface finish of a normal ball nose end mill. If you used the first calculator you would put the diameter that it gives you and use it as the diameter in the second one. The real beauty of the second one is that if you input a diameter and surface finish, it will inversely calculate the step over for you.

The cutting performance was evaluated in terms of cutting length and tool wear. However, the milling tests were performed at finishing cutting conditions with a two fluted solid carbide ball nose end mill (diameter d is 16 mm, TiCN coating). Nevertheless, this investigation focuses mainly on the flank wear of ball nose end mill.

Calculate the Feed per Tooth, based on the Chip load and Chip thinning factors: F z = C L × R C T F × A C T F. Calculate the RPM from the Cutting Speed and Cutter Diameter: n = V c × 12 π × D. * If your Vc is in m/min units use 1000 instaed of 12 in the above formula. Final Stage: Calculate the Table Feed: V f = F z × n × Z.

These three are examples of standard end mills made of tungsten steel. In contrast to the flat end milling cutter, which has a pointy nose, the round nose milling cutter has a rounded nose. This is also referred to as the R angle, which is another common term. Contouring is the primary use for the ball cutter.
