For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
The first operation will be rough cut with end mill followed by the finishing operation by ball end mill. When ball end mill moves near the corner, it leaves around edges. The chamfer on the hole: Chamfer around the edges of the hole is recommended. This will help in smoother pin movement and fasteners insertion.
