3.1.7.2.4 Break Down Pass W-Forming
This function is a part of the Toolbox Tube Design and creates the tube profile for a break down
pass. W-Forming is a special forming method which raises the middle of the profile first while the

Button Break Down Pass, W-Forming from the Toolbox Tube Design.
The window Break Down Pass, W-Forming is opened. Enter the desired Angle and Radius for
the first arc segment and the Radius for the second arc segment into the input fields.

break down pass, the developed length of which is the same as the one of the previously
appended profile list.
Principle of operation
After pressing the Ok-button the tube profile for the break down pass is entered into the profile list.
The first arc segment (at the bottom) has the desired angle and radius. The second one (at the
outside) has the desired radius and its angle is calculated on this way that the developed length of
the whole profile is the same as the one of the previously appended profile list.
For generating the rolls for the break down passes use the functions Break Down Pass, Bottom
Roll and Break Down Pass, Top Roll.
Hint:
· For creating the rolls for the break down pass, use the function Break Down Pass, Top Roll and
Break Down Pass, Bottom Roll.
