    Actual Working Diameter Parameter Adjustment Solution
        When machining at axial depths less that 1/2 the radius of the cutting tool, the actual diameter engaged in the cut changes and your parameters must be adjusted. The Effective Cutting Diameter engaged must be used for the calculations.

    Metric Radial Chip Thinning Feed Calculator Solution
      Whenever the axial depth is less than half the tool diameter (as in Ad2) the chip thickness is less than the feed per tooth and additional feed is possible using the chip thinning calculation. The Effective Diameter (Deff) must be used to properly calculate.

    Surface Finish Calculator Solution
        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.
