Din 5480 Spline Calculator Excel Verified //top\\

The geometry of involute splines requires solving the inverse involute function ( inv α to α ). This equation is transcendental (cannot be solved via simple algebra) and requires iteration using or similar methods.

Input standard designations directly from the physical DIN 5480-1 and DIN 5480-2 textbooks. Ensure your cell outputs perfectly match the printed values for tip, root, and reference circles.
