TheBall Mill Finish Calculatorcan be used when an endmillwith afull radius(aball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by theheightof the scallop, amd the scallop will be determined by the stepover distance between cuts.
As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if aballendmillis used. The size of the step-over distance and the tool diameter will determine the scallopheightbetween each step.
