Milling cutter - Wikipedia

Figure 1 shows a 2.000″ diameter ball nose end mill running at .125″ DOC and a .125″ radial DOC (step over). the effective diameter at this DOC is .968″. If the desired SFM is 500, the RPM would normally be set at 955 RPM for a 2.000″ diameter cutter. However, since the effective diameter is .968″, the RPM should be set at 1973 to achieve 500 SFM. This is an increase of more than ...

Analysis of Cutting Forces in Ball End Milling

End mills are the cutting tools (also called router bits) that are inserted into the collet of a spindle or router. It is the part that spins and does all of the cutting in all directions. Some end mills can plunge into the material (like drilling). All end mills have the ability to cut sideways (also called profiling).
