: Verify your calculator's handling of root circle tolerances, which are particularly complex for flank-centered splines. Cross-check your computed tolerances with the detailed procedure and Table 5 from DIN 5480-1 as described in the KISSsoft manual, which involves formulas based on the manufacturing process (e.g., cutting, cold roll forming).

Use these where refurbishment of pressure angle due to profile shift or clearance is needed.

: You need to design an internal spline with m=2.5, z=28, pressure angle 30°, fit H/h, flank centering.
