New
Click the New button to create a stage in the current setup.
Delete
Click this button to delete a stage. The program will pop up an eta/DYNAFORM Question dialog box illustrated in Figure 8.6.12. Click OK to delete the current stage, or click Cancel to cancel the current operation.

Current stage
The button for the current stage is pressed in the stage list. The user can click it to confirm.
Tool control
This function is used to control the tool in the current stage. There are four control types for all the tools. As roller means to take this tool as a roller and click the Edit button to define the path of the roller, as illustrated in Figure 8.6.13. Stationary means the tool stays stationary. Force means the tool applies the force load along the working direction. Non-active means the tool is not active.
Figure 8.6.13 Define path
Path
Click Create path button to pop up a dialog box illustrated in Figure 8.6.14. Click the Elements button to select the elements which the path passes through (usually, flange element). Then, click the Start Node button and End Node buttons respectively to select the two ends of the path. If the obtained path is not in accordance with the requirement, click the Reverse button to change the path direction. Once the Create Line is checked, a path line will be obtained when generating the path.
Figure 8.6.14 Create path
Click the Select path button to pop up a dialog box illustrated in Figure 8.6.15. The user may select an existing line as the path for roller.

Click the Reverse button to reverse the path direction of roller.
Direction
The user could also select a second line as the auxiliary line of the roller path in order to adjust the roller path. Click the Define by Flange button to pop up a Select Elements dialog box illustrated in Figure 8.6.16. Or click the Define by Curve button to pop up a Select Line dialog box illustrated in Figure 8.6.17 to select a line as the auxiliary line of the path.

Edit
Besides the path, the user may also set some other parameters for the roller.
Taper angle: the angle between roller and the horizontal plane of outer panel.
Lead angle: the angle between roller and normal direction of path.
Position X: the displacement value of roller in X direction.
Position Y: the displacement value of roller in Y direction.
Position Z: the displacement value of roller in Z direction.
Velocity
The user may specify the velocity of roller. The default is 2000.
Springback
Springback seamless: This button is toggled off by default. The user could toggle it on to perform springback calculation after rotary bending.
Edit: Click this button to edit the springback parameters.
D3plot
There are three methods to define the number of output frames. First, the user defines the total frames, and the program will automatically calculate the time interval and export it to the card. Second, the user enters a time interval and exports it to the card. Third, the user specifies the interval for the roller path, and the program will calculate the time interval accordingly and export it to the card.
