Feb 25, 2021 · End mills are machining tools which are similar in appearance to drill bits, and perform various types of cutting and machining of metals. A ball end mill is a type of end mill that is especially suited to machining three-dimensional contoured shapes, such as those in molds and dies. It has a rounded tip which is designed to give an improved surface finish to the material being cut

ball nose mill and mill marks? | mcad central

Dec 01, 2004 · When using a ball end mill with a small step depth or scallop height, you can, and probably should, boost your feedrate. The reasoning is simple. As the depth of cut gets shallower, less of the tool is engaged in the part. The chip becomes thinner. Radial force becomes correspondingly less
