The user needs to define a new simulation before adding to Auto Setup. Click SETUP/AUTOSETUP menu, if there is no existing Auto Setup information in user’s database, the program will automatically add new simulation and guide user to setup. If there is defined Auto Setup information in the database, the program will automatically enter the defined Auto Setup to edit.
NOTE: The user is allowed to set only one Auto Setup project in one eta/DYNAFORM database.
Figure 8.2.1 New Auto Setup Setting
8.2.1.1 SIMULATION TYPE
There are two simulation types in the new Auto Setup. One is sheet forming, which include traditional normal sheet forming and blank hydro forming. The other one is tubular hydro forming.
8.2.1.2 PROCESS
The new Auto Setup includes 6 ordinary process templates and an empty template as shown in Figure 8.2.2.
Figure 8.2.2 Process
<VOID>: program does not provide any default setup. Users may define their own set up according to their requirement.
CRASH FORM: draw forming without closing ring.
SINGLE ACTION: single action forming simulation.
DOUBLE ACTION: double action forming simulation.
TRIPLE ACTION: triple action forming simulation.
GRAVITY: gravity forming simulation
SPRINGBACK: springback simulation.
8.2.1.3 BLANK THICKNESS
At the beginning of a new setup, the program will prompt user to enter a default blank thickness. If the default blank thickness is defined, this value will be automatically set to the defined blank. The user may go to blank define page to modify a certain blank thickness. Default blank thickness is 1.0 (mm).
8.2.1.4 BLANK SURFACE
In real simulation process, the user usually generates die and punch surface automatically from the original part surface. There is only one part surface. However, in practical operating process, die and punch have different surfaces. It is required to define side of the part surface which is used to generate die face: top, middle or bottom. The program will automatically set up the contact OFFSET value on the other side of the surface.
If physical offset die and punch surface are used, the user should select the fourth option DUAL. Refer to the Figure 8.2.3 for more explanation.
a) Tools refer to the Top surface of part
b) Tools refer to the Middle surface of part
c) Tools refer to the Bottom surface of part
d) Tools refer to the DUAL surface of part
