Using the Grid Angle Cut Wizard

Grid Angle Cut Wizard finds the ply corners where angle cuts are required.

  1. Select the Plies group.
  2. Define the analysis criteria:
    • Minimum cutting length of the machine.
    • Width of the tows/tape laid down by the machine.
    • Required angle between tangent and ply orientation.
  3. Click Analysis (Compulsory).

    The wizard:

    • Finds all the ply contour vertices with discontinuities in tangency.
    • Ignores those where the discontinuity is already the result of an angle cut.
    • Checks the angle between the tangents at the vertices and ignores the vertices where this angle is too large.
    • Checks the angle between each tangent and the ply orientation and ignores the vertices where this angle is lower than Required angle between tangent and ply orientation.
    • Finds out whether an angle cut is required or not.
    • Ignores vertices where the ply orientation is not consistent with the tangents.

    The wizard groups the vertices coming from the same ramp support, according to orientation and tangency criteria.

    Within a given group, the vertices are ordered according to their abscissa along an average bisector.

    Those groups are displayed in the work area.

  4. Optional: Check Selected all vertices in corner to select all the vertices, whatever their orientation is.
  5. Click a callout.
  6. Create manual angle cuts.
    When the angle cuts are created for a group, its callout disappears, and you can proceed with the next group.
