This task explains how to create
a stamp from punch and die features.
First, you will define a punch and a die in Part Design, in the absolute
axis-system.
Then, in a Sheet Metal part, you will bring the punch and the die features
(and their axis system) to a point you have selected. If necessary, you
will define a rotation of the axis system from a reference line. |
|
This user-defined stamping cannot be combined
with the Opening and Cutting Faces approach. |
|
|
|
All .CATParts are available from the samples directory (PunchDie1.CATPart,
Punch1.CATPart and
Die1.CATPart or
NEWPunchDie1.CATPart,
NEWPunch1.CATPart and
NEWDie1.CATPart for Generative Sheetmetal Design or
Aero_PunchDie1.CATPart,
Aero_Punch1.CATPart and
Aero_Die1.CATPart for Aerospace Sheetmetal Design). |

Creating Stamps
|
|
-
Start the Part Design workbench.
-
Insert a body (menu Insert > Body) to define
the punch.
-
Enter the sketcher
select the yz plane, and draw the profile of the punch, and a rotation
shaft.
The punch must be oriented as described in Defining the Punch in
Relation to the base feature to be Stamped in the Creating
User-Defined Stamping Features chapter. |
|
|
|
|
|
-
Return to the 3D space and create the punch using Shaft
.
-
Repeat from step 2 to step 4 to define the die, making
sure that it is oriented as described in Defining the Die in Relation to
the base feature to be Stamped in the Creating User-Defined Stamping
Features chapter.
-
Return to the Sheet Metal application, and if needed, use
the Define In Work Object on the PartBody containing the wall
or the base feature to be stamped.
-
Click User
Stamping
from
the Stamping tool bar and select a base feature, or a face where the
stamping is to be created.
This base feature or face is used to define the stamping location and
direction, by matching the punch's origin to the selected point on the
base feature.
The User Defined Stamp Definition dialog box is displayed: |
|
|
-
Make sure the With die
icon is pressed down and
select the Punch feature from the specification tree.
The punch's positioning is previewed in the geometry. |
|
|
-
Select the Die feature.
The die's positioning is previewed in the geometry as well. |
|
|
-
Check the No Fillet button is you do not wish the stamp
to be filleted, or set the radius value if you wish the stamp to be
filleted.
|
|
|
Stamp without fillet |
|
Stamp with fillet |
|
-
If needed, define the stamp's positioning on the selected
base feature by choosing:
-
a
Reference for rotation: by default, it is the sketch axis,
but you can also select any line or edge on base feature.
-
a
Rotation angle value: you can either enter a value in the
dialog box, or use the manipulator in the geometry to define this
value.
-
a new
Origin point on the base feature to coincide with the punch's
point of origin.
This is especially useful for non-circular stamps, but you can
very well create the stamp as is, without further positioning. |
-
If needed, select the On
Context check box (in the Generative Sheetmetal Design workbench
only).
The punch and die's positioning is previewed on the geometry.
-
Click OK to validate and create the stamping.
By default the Punch and Die parts are set in No Show mode when clicking
OK to create the stamp on the base feature.
|
|
|
- Radius is the radius of the bend between the
stamping and the base feature.
- Punch and Die are the bodies you have
defined previously. If the punch and the die are in another CATPart
document, activate this document before clicking the punch or the
die.
- If you select two reference lines in addition to the plane,
this will create two editable constraints to position the stamping.
These constraints are editable.
- A user-defined stamping can be edited (punch, die, position,
constraints).
- As the punch and die are not symmetrical, you cannot create
such features as a cutout, a hole, a corner, etc., on this kind of
stamping.
|
|
|
- If you enter a punch and a die, the stamping is the difference
of the shape of both features.
- The punch height cannot be superior to the base feature height,
otherwise it is considered as a cutout.
- You may create a user-defined stamping from a punch only but
you cannot create a fillet.
- Only the stamping sketch is displayed in unfolded views.
|
|
|
|
In this case, make sure you select the Define In Work
Object on the PartBody containing the base feature to be
stamped, prior to actually creating the stamp.
or as two separate Part Design parts (Punch1.CATPart
and
Die1.CATPart from the samples directory)
In this case, when selecting the punch or die feature, the
system automatically copies this feature into the .CATPart document
into which the base feature to be stamped is located.
A link is retained between the initial punch or die feature and its
copy.

|
Inserting Punch and Die features From The Catalog
|
|
Open the
NEWstamping_catalog.CATPart document. All .CATParts and catalog are
available from the sample directory (Die.CATPart,
Punch.CATPart,
UserStamp_Catalog.catalog). |
|
-
Select the face of the part where the stamping is to be
created.
-
Click User Stamping
from the Stamping toolbar
to open the User-Defined Stamp Definition dialog box.
-
Click With die
.
-
Click catalog
to select a Punch feature
from the catalog.
The Catalog Browser dialog box is displayed.
-
Browse to the directory where
UserStamp_Catalog.catalog is filed.
-
Double-click on chapter UserStamp.
The parts saved in the catalog are displayed.
-
Select the Punch, then click on OK.
The body of this punch is aggregated under the part in the specification
tree. It is referenced in the User-defined Stamp Definition dialog box as
Result of Punch.
-
Select the Die field to activate it.
-
Click catalog
to select a Die feature from
the catalog.
The Catalog Browser dialog box is displayed.
-
Browse to the directory where
UserStamp_Catalog.catalog is filed.
-
Double click on chapter UserStamp.
-
Select the Die to select it then click on OK.
The body of this die is aggregated under the part in the specification
tree. It is referenced in the User-defined Stamp Definition dialog box as
Result of Die.
A punch and a die are now available for you to create a user-stamp.
-
Click on OK to create your stamp.
|
|
|
- To insert a feature from the catalog, the appropriate field has
to be selected first in the User-defined Stamp Definition dialog
box.
- When creating a stamp from a catalog's feature, the
Position on context option is deactivated. This is due to the
fact that the stamping feature of the catalog was previously
defined in its own axis-system. The part's canonic axis-system and
the catalog's being different, there is no reason to use the
option.
Yet, when editing a user-stamp created from a catalog's features or
using a body imported from another user-stamp, the option is
activated.
|
|
|
You cannot instantiate a Power Copy from a catalog, only parts.
