Creating a Press Direction

This task shows you how to analyze geometrical elements to create and optimize a press direction.
Open the StampingDirection01.CATPart from the samples directory.

  1. Click Create Press Direction   in the Process Part Separtion toolbar.
    If the check box Display detailed text in dialog in Tools/Options/Mechanical Design/Die Face Design is cleared, the dialog box looks like this:


    If the check box Display detailed text in dialog in Tools/Options/Mechanical Design/Die Face Design is selected, the dialog box looks like this:


    When required, click Open to access the dialog boxes.

  2. Select the elements to analyze.
    The selection determines the proposed analyses:
    • Draft and Depth analyses when only surfaces are selected.
    • Shear angle analysis when only wires are selected.
    • Draft, Depth, Shear angle, Normals, 2D/3D Cut when both surfaces and wires are selected.

  3. Manage the analyses:
    • Select an analysis from the list.
      If only wires are selected, a support surface may be required to perform some analyses.
      Some surfaces are automatically retrieved.
    • Click Detailed Analysis.

      or
    • Follwo the messages or labels to check and correct errors.
    • When necessary, edit the Options to modify the analysis behavior.

  4. Go to the Optimization section to optimize the cam direction with respect to the displayed analyses.
    • Cone Variation Angle: Defines an angle around the current position to compute the best position.
    • Center: Centers the axis origin on the analyzed elements. If surfaces and wires are selected, only curves are taken into account.
    • Mean Normal: Computes the mean normal of the elements to align the Z-Axis on this normal.
    • Edit Coordinates: Edits the coordinates of the compass.
    • Convert to Cam: Converts the current position of the compass into a cam compatible solution.

  5. Click Automated Optimization to center the axis on the analyzed elements, find the best solution within a given cone variation angle and convert the computed best solution to a cam compatible solution.

  6. Go to Extract Geometry to convert the results of the displayed analysis to dead geometry.
    • Extract Areas: Results are stored as dead geometries and 3D labels.
    • Use Local Minima and Maxima for Extract Areas: The number and locations of the 3D labels are optimized to match the extremum analysis values.
    • Extract Analyses as Points
    • Extract Direction: Extracts the Z-Axis on each analyzed point.
