# Ball-end milling scallop height
# Scope: Ball-end cutter geometric scallop between parallel passes; flat surface.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

radius = 3 mm
stepover = 0.5 mm

height := radius-sqrt(radius^2-stepover^2/4) [mm]

check scallop budget: height <= 0.02 mm

scenario alternative: radius = 2.4 mm
