PROGRAMMING A BEND
Enter the thickness and the tools if they differ from the product in the
course of production.
To speed up programming, the p/m fields as well as the material are
taken over from sequence 1 of the product currently in hand. The
modification of these data does not affect the programme that is running.
Enter the angle of the bend in the field
Enter the height Lof the wing (external measurement) and the position of
the X gauge will be calculated automatically.
or
directly enter the distance at which the X
gauge is to be positioned. L
Enter the length of the bend.
The system automatically calculates the pressure and bending.
Possibly also enter,
ohow long the pressure is to be maintained (if not
programmed, the default is = 0.5 s),
othe retraction of the gauge,
othe reduction in bending speed,
oslow lifting, etc.

EASY BEND PAGE PAGE 7
Press the START button or the pedal and the axes will position to the
desired values. The numerical command will automatically go into semi-
automatic mode.
Actuate the pedal to bend.
When the beam returns, the DNC switches to programming mode.
You can now enter new data or actuate the pedal for a new bend.
Hit the key to return to production mode.
FIELD OVERVIEW
See Field Overview, page 9.

CREATING A PRODUCT
This paragraph explains how to programme a product as well as the method
for correcting and recording it.
USING THE SEQUENCE PAGE
This page displays all the bending informations for the current sequence.
That is the requested position of the Y and X (R, etc.) axes, the pressure, the
gauge retraction, the crowning, the dwell time, etc.
Important This page displays the result of the calculations made when programming a
product in the L-alpha page with definition of the bending order.
The operator can modify these values if necessary (especially the retraction,
the dwell time, the top dead center).
However he must avoid to directly modify the Y and X values calculated by
the DNC.
Hint An operator can directly program a product in this page, without "passing"
through the L-alpha page and definition of the bending order.
This simplifies the manipulations a great deal, since all the informations
required for the bending are on this page.
To reach the sequence page, press the key.
Pressing once will display the page in large characters, pressing twice
will display all dimensions and functions of the current sequence in small
characters.
Pressing the key 3 times will display the main sequence data in large
characters, with a graphic of the part underneath.
This page is displayed during the powering-on of the DNC.
To change from one sequence to another, press the or key.
In order to add a new sequence with the same content as the last sequence at
the end of the program, press , then 1when the warning message
displays.
In order to insert after the current sequence a sequence with the same content
as the current one, press when the cursor is on the N field.
The key is used to move the cursor from one significant field to
another.
The key is used to move the cursor across all the fields. This function
can be deactivated in the user preferences.
PAGE 8 USER GUIDE DNC 600S

If a product is removed, the data contained in the tool fields, the thickness
field and the material information fields continue to be displayed. This saves
the operator from having to reprogramme unchanged data.

FIELD OVERVIEW
PNumber of the product in the work memory.
P+ Number of the following product when there is
a sequence of programmes.
NBending order (sequence) number to be made
and the total number of bends for the product.
CY Number of sequence repetitions.
(programmed 0, the sequence is jumped)
Th Material thickness.
The Greek symbol "Sigma" indicates the
tensile and rupture strength.
This field, as well as those showing the type of
material, can be hidden (see the preferences
page in the machine parameters).
If this field is hidden, the default value is steel
45 kg/mm2, but other values can be defined in
the ad hoc field in the machine parameters.
p/d Number of the punch/die pair associated with
the bend to be made.
In the P or D field press to display the list
of tools.

Select the tool in the list then press again
to return.
CR/ri Number of bends requested when working
with step bending (min. 4), and internal
bending radius.
--MEM-- This column contains either the values
calculated by the system when simulating, or
the values programmed by the operator.
--POS-- This column indicates the real axes' positions.
--COR-- This column contains all the sequence and
product corrections introduced on the
CORRECTION page.
The , Y1, Y2,etc. fields are dependant on the axes programmed in
the numerical control.
L Height of the wing after bending. The DNC
will automatically calculate the position of the
back gauge of axis X.
QQuantity of products to be produced. The Q
field is displayed only if the parameter in the
PREFERENCES page is activated.
Lmat Bending length.
TON Bending force.
Rx Back gauge retraction. The operator indicates
in mm the retraction distance. If nothing is
programmed, the beam doesn't stop at the PP.
No retraction.
If value 0 is introduced, the beam stops at the
PP, then executes immediately the bend
without carrying out a retraction.
The field between the Rx and the retraction
value serves to define the retraction mode.
_ = the beam stops at the PP and waits till the
retraction is made, in order to carry out the
bend.
1 = the beam stops at the PP, then continues
immediately, at the same time as the
retraction is carrying out.
Ext start If nothing is programmed in this field, the axes
start automatically from the BDC, from the PP
or from the TDC, depending on the choice
made in the machine parameters.
If 1is programmed, the start will be made as a
function of the configuration made by the

constructor.
- In most of the configurations, it will be
sufficient to give a down command. At this
command, the axes take position, then a
second down command has to be given, in
order to move the beam.
- In other configurations, the provided start
button must be pressed.
- When the message TOL ZONE appears,
that means that a down command has been
given and that the axes are not positionned
in the current sequence. Give a start with
the provided button or on the front panel of
the DNC.
Vy Beam bending speed.
Programmed at 0, the speed is 1 mm/s.
Programmed at 9, the speed is 10 mm/s.
(If the machine is capable of reaching this
speed)
Vy Rising speed from BDC to PP.
Programmable from 0 (slow) to 9 (fast).
Allows to vary the speed at which the beam
rises to the PP. (Function depending on the
machine's hydraulics).
ΔTDwell time.
TDC Distance from top dead center.
SP Distance from the beam speed changing point.
(Switch Point).
F1: - F5:, Cr Value of the auxiliary functions F1 to F5 and
crowning.
These fields can also be re-programmed by the user.
However, certain fields are related, that is modifying one provokes a
modification of the other.
