Milling Step over Distance CalculatorCustomPart
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.
