Helical Gear Generator [portable]

| Challenge | Solution | |-----------|----------| | | Apply profile shift (X-factor) or warn user | | Self-intersecting sweeps for large helix angle | Check sweep path curvature; use smaller step size or exact B-Rep sweeping | | Low resolution at tooth tip | Adaptive point distribution: more points near tip where curvature changes rapidly | | Non-manifold edges after patterning | Merge coincident faces with tolerance-based stitching | | Performance for high tooth counts (>200) | Reduce profile resolution for preview; use high-res only for final export |

However, for a helical gear generator, we must differentiate between the ((m_t)) and the normal module ((m_n)): [ m_n = m_t \cdot \cos(\beta) ] Where ( \beta ) is the helix angle. helical gear generator

The next generation of gear generators is moving away from traditional involute curves. | Challenge | Solution | |-----------|----------| | |

: Generators often support both the Normal system (where tooth profile is defined perpendicular to the teeth) and the Radial system (where the gear diameter remains fixed regardless of the helix angle). Modern implementations use B-Rep kernels (OpenCASCADE

Modern implementations use B-Rep kernels (OpenCASCADE, Parasolid) for efficiency.
