Inventor CAM supports chamfering with ball end mills and bull end mills. This may be useful in cases where you are already using a ball or bull end mill in a part and wish to chamfer off sharp edges, but save a tool change to an ordinary chamfering tool. With small chamfer sizes, the differences between a flat chamfer using a chamfering tool and a slightly rounded chamfer may be negligible.

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between.
