The addendum of the rack reference profile haP0 determines the tooth root diameter of the gear. It often refers to the profile reference line for the tooth thickness sP0, but can also refer to the profile reference line of the manufacturing pitch circle.
The following input options are available:
- Addendum coefficient (haP0*=haP0/mnP0)
- Addendum (haP0)
- Distance of tool tip line to manufacturing pitch circle (AKOW)
sP0=0.5·π·mnP0 (is equal to half pitch)
| haP0 | Addendum of the rack reference profile |
| haP0* | Addendum of the rack reference profile module-related |
| sP0 | Tooth thickness at the reference line of the rack reference profile |
| AKOW | Distance of tool tip line to manufacturing pitch circle |
| C | Reference line of the manufacturing pitch circle |
| mnP0 | Normal module of the rack reference profile |
