ModifyCompensatorBlankholder Addendum and Part

The Blank-Holder Addendum and Part command enables you to modify the die environment based on the result obtained by the adaptation/compensation process.

During the die design process, you might have completed one or more process compensation obtaining some deformed surfaces. These deformations compensate only the Part areas of the die. The Blank-Holder Addendum and Part command enables you to change other portions of the die to accommodate the compensation result.

On starting the command, you need to make the following inputs in the form of solid skins, refer to the image below.

1	Blankholder	It is the area that connects the Addendum to the die sides.
2	Addendum	It is the portion of the die that has to change to accommodate the compensated parts.
Following inputs can be made in groups.
3	Closing faces	It represents the holes (open areas) of the part.
4	Deformed Surface	It is the GSM surface (containing the computed transformation) obtained after applying the process compensation or adaptation.
5	Part	It is the part on which compensation/adaptation has been applied.

To make selections under multiple groups, use the Next Group button available besides Group. You can return to the previous group by selecting the Previous Group button. The current group number is displayed in the corresponding text box.

Using the options under the GSM options node, you can make the settings for various GSM parameters. The values of Bulge (see "An example of the Bulge factor") and of Roundness (see "An example of Roundness") can be set. Under the Precision node, you can define the various tolerance values.

Under the More Options node, following options are available:

• Approximation node - make various settings for approximation.
• The With Fixed Compensated Part check box enables you to define whether the compensated part remains fixed or not while applying the command.
  • When selected, the deformed parts remain as fixed and the Blankholder is rigidly moved (without any scaling) to match the part.
  • When cleared, the Blankholder remains fixed, and the deformed parts are rigidly moved together to match the Blankholder.
    
    

Some results are shown below:

1. The original die parts.
2. With the With Fixed Compensated Part check box cleared.
3. With the With Fixed Compensated Part check box selected.
