Why “Excel Verified” Matters
In the engineering world, “verified” is not a buzzword. It means that every formula, lookup table, and conditional logic within the spreadsheet has been cross-checked against: din 5480 spline calculator excel verified

To verify an Excel-based calculator, ensure it uses these standard geometric formulas based on the module ( ) and number of teeth ( Reference Diameter ( ): Base Circle Diameter ( ): External Tip Diameter ( da1d sub a 1 end-sub ): For a verified DIN 5480 spline calculator in
- m = 2 mm, z = 30, α = 30°, external spline, fit H/h.
- Reference diameter = 60 mm.
- Tip diameter = 64 mm.
- Root diameter = 55.6 mm.
- Measurement over pins (pin diameter 3.0 mm) = approximately 66.05 mm (exact value from standard).
): Determines the tooth size (ranging from 0.5 to 10 in the standard). Number of Teeth ( ): Typically between 6 and 82. Pressure Angle ( ): Always 30° for standard DIN 5480 profiles. Tolerance Class: Ranges from 5 to 12 (lower is tighter). Deviation Series: Lowercase letters for shafts (e.g., ) and uppercase for hubs (e.g., 2.
