| Problem | Symptom | Solution | |---------|---------|----------| | Circular reference | Excel prompts error | Enable iterative calculation (Options → Formulas → Enable iterative calculation, max 100 iterations). | | Missing over-pin formula | No output for Mdk | Manually add formula: ( M_dk = d_m + \fracd_m\cos \phi_M ) with phi_M based on contact angle. | | Wrong profile shift sign | Negative dedendum | Verify: For external splines, x>0 increases tooth thickness. | | No tolerance tables | Class selection does nothing | Create named range tolerance_table and use INDEX(MATCH()). |
