This function
is used to estimate the elongation ratio of the blank along the specified
profile direction. It is useful for estimating the level of blank
deformation.
If this function
is selected, the user needs to select a profile. After selecting a profile, two
section lines are highlighted as illustrated in Figure 7.3.57. These section lines are created from
the plane of the profile intersecting with the binder and the die.

Next, the
user selects a reference point on the highlighted line or clicks the middle
button to select the default point. As illustrated in Figure 7.3.58, the lines are divided into three
lines identified as 1, 2, 3 respectively. The result is printed in the message
prompt window:
ELONGATION: 23%; LENGTH: 1:
434.1 2:521.7 3:207.7
ELONGATION is the elongation percentage of the
specified section line after deformation. It is calculated by the following
equation:
ELONGATION
= (LENGTH 1+ LENGTH 3 -LENGTH 2)/ LENGTH2 *100%
LENGTH 1 and LENGTH 3 indicate the lengths of the punch
and addendum after deformation, respectively. LENGTH 2 indicates the length of the line 2 prior to deformation.
Then, the user continues by selecting another profile or click on the
right mouse button to exit the function.
