Once the stamped part data are imported, perform part mesh and mesh check/repair to strictly control the mesh quality. Then pick the outline and related trim line of scrap, and use them to trim the stamped part to obtain the scrap to be analyzed.
Since the shedding condition for each scrap is different during calculation, the user needs to put each scrap on a different layer, and set color for each scrap, then define the material parameters respectively.
In Scrap Setup interface, the user can define Part, Material and Thickness, move and display scrap, define contact, and define single point constraint.
GEOMETRY
PARTS
Enable the user to define scrap by selecting Part or directly import mesh file, as illustrated in Figure 11.2.4. After clicking the Define geometry button, the program will pop up a Define Geometry dialog box, as illustrated in Figure 11.2.5.

Define scrap
ADD PART: Select one or multiple parts to define scrap. The selected parts will be displayed in Part List.
REMOVE PART: Remove the selected parts from Part List.
ADD ELEM: Add the selected element to the current selected part.
COPY ELEM: Copy or offset a new element from the existing element. The new element will be added to a default part and this part will be named as Scrap.
DISPLAY: Display all the parts defined in the part list for the user to check and repair mesh.
EXIT: Exit the Define Scrap dialog box.
Once the scrap parts are defined, all the defined parts will display under the Part label. At present, the program has already defined the default material, thickness and property automatically for each scrap part. The user can modify these default material, thickness and property according to the practical situation.
MATERIAL
The program will define a default 18# material for each defined scrap part, as illustrated in Figure 11.2.6.
Figure 11.2.6 Scrap material
Note: If the user does not specify material for scrap, BLANKMAT will display on the Define Material button. Once the material is specified for the scrap, the material name will display on this button.
Individual: Modify the material type for individual scrap or all scraps. If this option is toggled on, the user is allowed to define different material type for each scrap. If this option is not toggled on, the material type of all the other scraps will change when the material type of one scrap is defined or modified, namely, define one scrap, then define all.
The user can enter the material definition
interface to modify or create a material by clicking button. Refer to Section 8.3.4.2 for a detailed description of
material creation and modification.
GENERAL
This function allows the user to specify a proper position for the defined scrap and set contact between scraps. The Show Scrap option only displays the defined scrap. After this option is toggled on, the defined scraps will be displayed in the display window and the other parts are closed.
MOVE
Adjust the position of each scrap, as illustrated in Figure 11.2.7. Click the Move button to pop up a Move dialog box as illustrated in Figure 11.2.8.

Move scrap
DESELECT ALL: Enable the user to deselect the selected scrap. The button is grey. Once the user selects the scrap, this button will be highlighted.
SELECT PARTS: Enable the user to directly select parts to be moved in the screen window. The user can select parts to be moved directly from the scrap list, or click this button to pop up the Select Part dialog box. The selected parts will be highlighted no matter which selection method is used.
DIRECTION: Enable the user to translate scrap along X, Y and Z directions. The user can enter a value in the Distance box. Click the Apply button to confirm or click the Reverse button to reverse the direction.
EXIT: Enable the user to exit the Move dialog box.
SET SCRAP CONTACT
This function
allows the user to define the contact between scraps. If this option is toggled
on, the define button
is highlighted and the user may define contact
according to the requirements. Refer to Section 8.3.4.2 for a detailed description.
SINGLE POINT
CONSTRAINTS (SPCs)
This function allows the user to define single point constraints. The user may click the Edit button to display a dialog box illustrated in Figure 11.2.9 Refer to Section 8.3.4.4 for a detailed description of constraint definition.
