Process Orientation

Create the forming shape (where the part is gradually unfolded) by defining the appropriate transfer shape over a selected blank. Transfer shapes are used to create the minimum area nesting shapes (to use the minimum material) for the Transfer die. The forming shape includes the selected blank(s) and the chosen transfer shape.

Only one forming shape can be added to the tree, you can edit the part by selecting the function on the side bar.

Usage Example

Selected blanks:

 

Transfer Shapes for the selected blanks:

 

Rectangle:

Parallelogram:

Miter:

 

 

 

Trapezoid:

Chevron:

Arcs:
   

Process

  1. Click the button in the menu on the right hand side of the graphics pane to open the function.

    The Feature Guide is shown here:

    Tip: You can open the Feature Guide at any time by right-clicking the mouse in the graphic display area.

  2. Required Step 1: Pick the blank (2D closed wire). 

    The next step begins automatically.

  3. Required Step 2: Define the nesting shape and set the parameters to achieve the best utilization.
    The following parameters are displayed:

    Rectangle

    This is a dropdown list that enables you to select the required transfer shape. the following options are available - click Examples below the descriptions to view images:

    Rectangle

    The rectangle shape consists of 4 lines which are perpendicular to each other.

    Parallelogram

    The parallelogram shape consists of 2 pairs of parallel lines.

    Miter

    The miter shape consists of 3 lines which are perpendicular to each other and 1 line with an angle.

    Trapezoid

    The trapezoid shape consists of 2 parallel lines and 2 inclined lines.

    Chevron

    The chevron shape (dart or arrowhead) consists of a concave quadrilateral with one interior reflex angle (>180° but <360°).

    Arcs

    The arcs shape consists of 2 parallel lines and 2 arcs with the same radius

    Examples:Examples:

    Rectangle:

    Parallelogram:

    Miter:

    Trapezoid:

    Chevron:

    Arcs:

    Min. Angle

    The minimum angle defined for the shape. This parameter is displayed for all the shapes except for Rectangle.
    Default: 0. Valid values: 0 to <90.

    Auto Radius

    This parameter is only displayed for Arc shapes.

    This is a toggle option Auto Radius / User-Defined Radius that enables you to either use a system generated auto radius for the arcs or to manually set the radius of the arcs.
    Examples:Examples:

    If the user-defined radius is too small, a warning message is displayed showing the minimum acceptable radius.

    Min. Material / By Angle

    This is a toggle option Min. Material / By Angle that enables you to achieve the best material utilization whilst either changing or keeping the current orientation of the blank(s).

    Min. Material

    Achieve the minimum material utilization by changing the orientation the blank(s), if required, to achieve this.

    By Angle

    Achieve the minimum material utilization by keeping the current orientation of the blank(s).

    Rotate Blank 1

    Rotate the first selected blank, as required.
    See the note below regarding intersecting blanks.

    Rotate Blank 2

    Rotate the second selected blank, as required.
    See the note below regarding intersecting blanks.

    Width

    Set the width of the selected transfer shape.
    Examples:Examples:

    Default width for the transfer shape:

    User-defined width for the transfer shape; the difference between the default and the user-defined widths is divided between the top and bottom margins, as shown below:

    Horizontal Layout

    This is a toggle option Horizontal Layout / Vertical Layout that enables you to change the layout to achieve the required material utilization.
    Examples:Examples:

    Horizontal
    Layout:

    Vertical
    Layout:

    Create Wire

    This is a toggle option Create Wire / Create Face that enables you to either create transfer shapes wires or faces.
    Examples:Examples:

    Create
    Wire:

    Create
    Face:

    In addition to these parameters, the following data information and transfer shape parameters are displayed:

    Dropdown Data Information

    For each transfer shape selected and for every change to the parameter settings, the dropdown parameters display the following calculated data:

    Net Utilization

    The net nesting utilization according to the selected transfer shape and parameter settings.

    Blank Area

    The blank area according to the selected transfer shape and parameter settings.

    Shape Area

    The shape area according to the selected transfer shape and parameter settings.

    Scrap Area

    The scrap area according to the selected transfer shape and parameter settings.

    Transfer Shape Parameters

    Top, Bottom, Left and Right Margins

    The margin settings for each transfer shape.

    Shift X and Y

    The shift X and Y setting for each transfer shape.
    See the note below regarding intersecting blanks.

    Actual Distance

    The calculated actual distance between each of the selected blanks within the transfer shape.

    Note: If the blanks intersect each other due to the Shift X and Y or Rotate parameter settings, the relevant screen parameters are displayed in red.
    Examples:Examples:

    Intersection has occurred; the relevant parameters are displayed in red:

  4. Optional Step 1: Pick additional entities to be transferred.

    To transfer addition entities to the new forming shape, pick the required entities from the file containing the blank(s) selected in Required Step 1.

  5. Click OKOK or ApplyApply in the Feature Guide to complete the function.

    1. Blank
    2. Transfer Shape

    When completed, the new Process Orientation feature will appear in the Feature Tree
