Note 1:
The flattening bends are shown here with a special flattening punch, but this is not required.
Note 2:
When bottoming operation is selected, the end of bend position of the Y-axis beam is depend-
ing on the working tonnage. If however the force is sufficient for the beam to go to the calcu-
lated Y-axis end of bend position, the beam stroke will be limited by the position value.

α
The required angle of this bend. This parameter only appears if angle programming is
selected with the parameter 'Angle sel.' and the bend method is an air bend.
Bend position . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Y
The required Y-axis position for this bend. This parameter only appears if absolute pro-
gramming is selected with the parameter 'Angle sel.' This parameter also appears if the
bend method is bottoming and/or flattening.
Opening. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . DY
This parameter results in a certain gap opening between the punch and the die after the
bend. A positive value is the gap opening above Mute, a negative value below Mute.
When you want to limit the handling time of the product you can program a small posi-
tive or a negative value.
Mute . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . M
Sequence point at which the Y-axis is switched from fast closing speed to pressing speed.
The value programmed here is the distance of the mute point above the plate. By default,
the mute value from the programmed die is used.
Whether or not this parameter is present depends on machine settings.
flattening 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 calcu-
lates 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 pro-
gramming a 'flattening offset'.
flattening and
bottoming The same as flattening, but now the control
assumes the top of the die as required Y-axis
position. The folded sheet is squeezed
between punch and die.
