• Approx chordal thickness st = s - (2·m·tan(α)/2)·(1 - cos(π / z)) — simplified: include chordal correction when converting arc to chord; for most moderate z, s is acceptable.
• For practical Excel, compute tooth thickness at pitch circle and optionally apply small chordal correction: Excel chordal factor: =B2*ASIN((s)/(B2))/PI()*A2 (advanced; see note)

A "deep paper" approach to this topic requires addressing the complex fit and tolerance systems defined in DIN 5480-1: Spline Calculator - Ondrives Precision Gears din 5480 spline calculator excel

A robust Excel tool must calculate "over pins" or "between pins" dimensions for quality control. Measurement Over Pins (External Spline) The dimension over pins ( Mkcap M sub k Headline: Stop Grinding Your Teeth Over Spline Calculations

• Correctly follows DIN 5480-1 (basic dimensions, module series 0.5–10 mm)
• Includes reference diameters, root/side fit definitions
• Handles both internal and external splines

The answer: Excel offers flexibility, transparency, and cost-effectiveness. Approx chordal thickness st = s - (2·m·tan(α)/2)·(1

FRENCO Spline Calculator: Specialises in converting inspection dimensions (like measurement over pins) into gear parameters. Spline Calculator - Ondrives Precision Gears

Useful for inspection setup
Calculates important values like base tangent length (Wk) and pin/ball measurement over/under wires, which are essential for checking actual splines with micrometers.
