  • A smaller diameter on the object results in surfaces which have sharper curves at the apexes of the curves.

  • A larger diameter on the object reverses this.

  • An amplitude adjuster can be used to modify these effects.
Phasing Holes 1/8 lobe
Works For End Cutting Near side cutting
Far side cutting, or using rear rubber column
Side Cutting Near side cutting
Far side cutting, or using rear rubber column
When using this for fluting, the use of an amplitude adjuster can help make a very design.
