TheBall MillFinishCalculatorcan be used when an end mill with a full 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. amd the scallop will be determined by the stepover distance between cuts.
1Calculationofball mill capacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin whendesigningand selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), thedegreeof grinding (product size), the …
The “SURFACE FINISH”calculatoralso includes a stepoveradjustment calculatorfor internal, and external radii. Aballnose end millmakes smaller scallops on an internal radius, and larger scallops on an external radius, and so it must be adjusted to maintain consistent surface finish. …
