# Deep-drawing blank and draw-ratio screening
# Scope: Cylindrical cup blank from area conservation; no thinning/flange allowance.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

diameter = 50 mm
height = 25 mm
limitingRatio = 2

blankDiameter := sqrt(diameter^2+4*diameter*height) [mm]
drawRatio := blankDiameter/diameter

check supplied draw ratio limit: drawRatio <= limitingRatio

scenario alternative: diameter = 40 mm
