Reducing the Radius of Fillets

You can reduce the radius of variable fillets, on top of constant fillets.Use Fillet Radius Reduction to reduce the radius of variable fillets, on top of constant fillets.

Before you begin: Search fillets as explained in Searching Fillets
  1. From the Die Face section of the action bar, click Fillet Radius Reduction .
  2. Select a Fillet Search feature, and click Apply.
    The fillets are reduced in several steps.
    • Extraction of the fillet rails, that represent the fixed part of the fillet boundary.
    • Smoothing of each rail, with a geometrical tolerance.
    • Computation of a sweep on each smoothed rail.
    • Extension of the sweeps on the side.
    • Computation of the intersection between the extended sweeps. The sweeps represent the fillet theoretical line.
    • Creation of a new fillet on the theoretical line, using the target reduced radius.
      Note: On variable fillets, the radii measured at 5mm intervals on the initial fillet are reported on the theoretical line, using the reduction value.
    • Projection of the boundary of the initial fillet on the new fillet. Fillet Radius Reduction uses this projection to split and relimit the new fillet.
    Joint areas are then morphed, using the initial boundary as reference, The target is the new boundary, computed by joining the reduced fillet and the no fillet area.
  3. Alternatively, select a reduction mode.
    • By Value. The fillet is reduced by the specified value
    • By Percentage. The fillet is reduced by the given percentage.
    • Target Radius. The fillet is reduced to the given value.
    • User Selection. You select a surface that represents the filled reduced surface.
    A Fillet Reduction Manager and the reduced fillets are created under the input parts.

  4. Clear the Reduce Joint Areas check box to skip the computation of joint areas, and save time.
  5. Explanations are displayed in the 3D area for fillets that are not reduced.
    1. Click a non reduced fillet to display intermediate geometries, and more details on the failure.

      These ntermediate geometries are available in the tree
