  • Ballnose Cut Depth Musings for Feeds and Speeds in G

    First Cut Depth is used to establish the effective diameter of the ballnosed endmill. This in turn is used to calculate the rpms from the surface speed. In this example we clearly want the effective diameter to be the whole diameter of the ballnose and entering that full depth as in the definition makes that clear.

  • 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.
