Cusp Height gives an idea of Surface Finish and is most accurate when applied to a flat surface.By reducing the Pitch of Step Over distance, Cusp Height is reduced and a finer finish is produced.If a desired Cusp Height is known, the appropriate Pitch can be calculated.

How to Size a Ball Mill -Design Calculator & Formula

Milling Step-over Distance Calculator In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. 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 a ball end mill is used.
