Spring-back Charts
Contents
Description
On the left side of the window, there is a list of all the dies in the die library. In the middle of the window, there is a chart of the spring-back values that the currently selected die has been tested for. The add, delete, and edit entry buttons are located below this chart. On the far right of the window, there is a full spring-back chart. If there are no spring-back values for the currently selected die, this chart will not appear.
How To
Start Up
To access the spring-back charts, click on the settings menu on the main tool bar. Click on the spring-back library option, as shown below.
Add Entry
To add an entry to a die, first click on the die in the die list to the left. Then click on the add entry button. 
After that is clicked, another small window will open. In this window, the date, the measured bend angle, and the spring-back(overbend) angle ban be supplied. The measured bend angle is the actual angle that the part was bent to. The spring-back or overbend angle is the angle that the part needed to be bent to to achieved the measured angle. Once this information is entered, click the green check button to add it to the spring-back chart.
Delete Entry
To delete an entry, first select the die that the entry will be deleted from. Select the entry in the entry chart by clicking in any cell in the entry's row. When a cell is selected, it will be highlighted in blue. Click on the delete button 
to remove it from the chart.
Edit Entry
To edit/change an entry's angle values, first select the die in the die list to the left. Select the entry in the entry chart by clicking in any cell in the entry's row. Once a cell is selected, it will be highlighted in blue. Click on the edit button. 
Once the edit button is clicked, the original entry menu will be opened. Edit any of the necessary information by changing the values in the given fields. Click the green check button to save the changes. To cancel editing and not save any changes, click the grey X button.
Full Chart
The angle values that were added to the entry chart will be highlighted in green, as shown below.
Caution: If the software detects any problems with the values that are generated, all or sections of the spring-back/overbend column will be highlighted in yellow. If this happens, please double check the entry values to ensure they are correct before proceeding.
Once a die has been given spring back entries, the spring angle values will be automatically generated in the results chart for each bend. For example, in the image below, the 150mm die was given entries for both 45° and 120° which were used to generated the full spring back chart. When a part is created using this die, the results chart will give the spring angle (the angle that the bend needs to be bent to in order to get the bend angle) for each bend in the spring angle column.
Help Videos
See image to the right. When this button is clicked, the attribute fields will have small help icons 
displayed next to them. (To hide the help icons, click the question mark button again.)
Click on any of these help icons to watch help videos that will visually explain these attributes. See image below. Use the play, pause and stop buttons in the bottom left corner of the window to control the video. Click the grey X button 
to close the video.
