Maths help please: Approximating a Flat Iteratively

Archie, you are a handy chap to have about, welcome to the forum :clap:

You all are working too hard :D Review my posted diagram. By using one leg of the right triangle as a line perpendicular to the midpoint of the flat, there is only one right triangle to solve for. The cutter is always tangent to the flat.
Sea.dog:
Doesn't your diagram assume the cutter is moving across the flat? It's only movement is, in fact, is along the diameter of the workpiece.

Use a 90 degree tool holder and the scallop is on the Z axis .

No, the cutter only moves towards or away from the spindle axis. The diagram shows the relative positions of the cutter, the flat, and the spindle axis. Rotate the diagram if you want to see the cutter at its actual position at any point along the flat.
