Bend parameters
Method
Select the required bending method. The control supports 4 methods:
• air bend
• bottoming
• hemming
• hemming & bottoming
• handling
Bend methods
air bend The sheet is bent to the programmed angle
by bringing the punch to the required depth.
The control calculates the required Y-axis
position to obtain the programmed angle.
bottoming The sheet is bent by pressing the sheet
between the punch and the die. The control
assumes the bottom of the die as required Y-
axis position.
hemming The sheet is folded in two. This is possible
after the sheet has been bent into a sharp
angle in a previous bend. The control
calculates the precise Y-axis position for this
action: the surface of the die plus twice the
sheet thickness.
Y-axis positioning can be adjusted by
programming a 'hem opening'.
hemming &
bottoming
The same as hemming, but now the control
assumes the top of the die as required Y-axis
position. The folded sheet is pressing
between punch and die.
handling No movement of the Y-axis, so the current
program step becomes a non-bending step.
Only the backgauge axes will position
according to the programmed values, e.g. in
order to enable handling of the product. An
external step change (C-input) is required.
