1. Understanding DIN 5480 basics (before Excel)

DIN 5480 replaces DIN 5482 and covers involute splines with module reference diameters. Key parameters: While there are several professional software tools for

• Graphics output – a plot of the spline profile (using XY scatter chart).
• Gauge diameter selection – recommends optimal pin/ball size.
• Export to DXF – using Excel VBA to generate a tooth profile for wire EDM programming.
• Batch processing – compute dozens of splines from a parts list.
• Error trapping – alerts if input combination violates DIN 5480 rules (e.g., profile shift too high causing undercut).

• z (Number of teeth)
• m (Module)
• α (Pressure angle)
• s (Tooth thickness)
• e (Space width)
• d (Pitch diameter)
• D (Major diameter)
• d1 (Minor diameter)
