Automatic Bar Nesting

 

 

 

This command allows to extruded bar in a support bar of the same section type.

After defining the Extruded Bar Nesting Characteristics, for both extruded bars and support, the parts will be automatically placed in the bars to optimize the loss rate of the bars required to place all the parts.

 

Creation stages / Use:

 

Click the icon or select the Nesting > Automatic Bar Nesting... command from the drop-down menu.

 

  1. Activate the Parts tab. Drag the parts to nest from the project tree.

  2. Activate the Supports tab. Drag the supports to use from the project tree.

  3. Choose the strategy.

  4. Choose the options.

  5. Validate .

 

 

 

  • The parts are placed according to the Z axis of the reference frame defined by the Extruded Bar Nesting Characteristics command.

  • Only one type of section, identical between parts and support, can be nested at a time.

  • It is the profile bounding boxes that are nested. No management of the possible reversals and/or cutting angles.

 

 

 

Save: This option allows to save settings. The nesting operation is created but it is not computed and assemblies documents are not created.

Recompute: The position of the already nested parts will be recalculated by taking into account the added parts. It is possible to increase or decrease the part quantity, as well the security gap.

 

The nesting window is composed of six tabs:

 

 

This tab allows to select the parts to nest by dragging them from the project tree and by filling the placing informations (quantity, rotation, cluster ...)

  • Parts are added by drag/drop:

    • of part documents into the parts list dialog.

A part can be placed if it follows these rules:

  • The document provides the Nesting Extruded Bar Component function. To do it, use the Extruded Bar Nesting Characteristics command.

  • The detailed representation contains only one shape.

    • or BOM. It allows you to:

    • Nest parts of an assembly.

    • Add n times all the parts of an assembly.

    • If the BOM contains manufacturing indexes, these are transferred to the parts in the documents produced by the nesting.

  • The quantity of each part to nest can be modified.

  • Priority: The nesting  takes supports with a priority of 1 (the smallest value) and places parts regarding their priorities. Then supports with priority 2 are completed with residual parts, always by considering their priorities. And so on....

Parts and supports priorities are independently considered.

  • The color of the placed piece is assigned automatically. However, it is possible to assign a different color to each piece.

  • Cluster: This option applies a strong constraint. The grouped part must be the only one nested until the desired number of part is placed. Then the other parts will be nested.

 

 

This tab allows to define the list of supports to use to nest parts and the nesting characteristics (quantities, border gaps).

  • Supports are added by drag/drop of part documents from the project tree into the supports list dialog. Use the Extruded Bar Nesting Characteristics command and select the Support mode.

  • Possibility to specify border gaps with different values on the left and on the right.

 

 

This tab summarize the contain of each placing. It displays the number of included support ( a support can be included several times if the parts quantity allows it) and the loss rate.

This tab is only displayed if the nesting has been calculated.

 

 

This tab allows to manage the nesting strategy.

  • Packing: Allows to define if the nested parts are on the left, or the right of the support. The loss is on the opposite side.

On the left: The packing is realized on the left of the support, the loss area is on the right.

On the right: The packing is realized on the right of the support, the loss area is on the left.

  • Cut gap: Gap between each part on the support.

  • Max time: This option allows you to limit the computing time allocated to the nesting.

 

 

The check of the consistency between the material of the part and the support can be activated. If it doesn't match, the nesting can't be validated.

It is possible to allow supports and parts without material. In this case, there will be no error.

  • The check of the consistency between the thickness of the tube and the support can be activated.

  • The Check quantity respected option allows to ensure that the requested quantity is respected.

  • The Invalid if a problem is detected option makes the document invalid if one of the strategy criterion isn't coherent (wrong quantity, material, thickness, ....)

 

 

This tab allows to manage default values for border gaps between parts and supports, the gap between supports, the text style to use and the template to use. These defaults values and options allow to fill the new documents dragged in this nesting.

  • The different gaps for all new dragged supports in the supports list can be filled with a default value.

  • The gap between supports can be filled by default.

  • The nesting text style can be selected or created. It is the text displayed in the nesting which indicates for example the loss.

  • An assembly template can be used. A nesting generates documents like assemblies, manufacturing, sheet metal manufacturing, ....) with a document by support and nested parts. The selected template will be used when creating the document.

 

 

Modifications / Additional information:

 

 

 

To use a symmetrical part a Mirror part must be created and it must be added to the parts to nest.

When creating the mirror document, the Extruded Bar Nesting Characteristics analysis operation is derived.
