Manual version V0606

PREFACE

This manual describes the operation of the Delem controller type DA-65W and is meant for
operators who are instructed for operation of the total machine.
Only authorised people should be able to create new or edit existing programs, as well as pro­gramming or editing of the tooldata. Therefore the controller has a keyswitch to prevent
uncontrolled programming. With the keyswitch in the off position the operator can only exe­cute a selected program. The operator cannot change the parameters to wrong, unwanted val­ues.

Version history

The control software is updated regularly to increase performance and add new functionality.
This manual is also updated as a result of changes in the control software. The following over­view shows the relation between software and manual versions.

1.5. Graphical programming

From the main menu you can select one of the programming possibilities.
In order to design or edit a new product, the graphical programming facility is present.
This facility is a complete product design tool that allows you to draw the profile of your prod­uct. It consists of a machine-and tool-library which allows you fast automatic, interactive or
manual bending sequence computations with display of possible product/tool/machine colli­sions and developed length.
The graphic design tool provides a way of selecting the most optimal bend sequence for a
product, keeping in mind the minimum production time and manipulation possibilities of the
product.

Features of the design tool

- Graphical design of product shapes in 2D and 3D (if available)

- Auto scaling

- Horizontal and vertical projected dimensions can be entered

- Blank length computation

- Real scale tool design

- 10 different upper side shapes and 10 different under side shapes (tables)

- Changing of lengths and angles

- Bumping (big radius)

- Adding or deleting of bends

- Existing products can be copied, changed and stored as a new product

- Production time indication

- Closing dimension or highest precision tolerance selection

- Connecting 2D programs for 3D-production

Bending sequence computation

- Fast automatic computation for minimum production time

- Interactive bending sequence fixation

- Manual bending sequence fixation

- Collision visualisation of product with tools and machine

- Free tool and machine shape selections

- Assignments of turn times, backgauge speed etc.

- Bending sequence simulation

- Free selection of R-axis position

Postprocessing of drawings

The postprocess facility computes:

- Fully automatic

- Machine adjustment such as:

• Y-axis position

• Decompression

• X-axis position

• X-axis retract

• Y-opening

• R-axes

The 2D-programming will be explained in chapter 2.
The 3D-programming (if available) will be explained in chapter 3.

1.5.1. Control keys

The drawing software uses several function keys on the front panel. The function depends on
the type of control (2D or 3D functionality)

- S1 thru 8

- Drawing cursor control with:

- Zoom function:

At bendsimulation overview in case of 2D-products (bendsequence menu and automatic
mode):

Reducement

- Drawing cursor control for 2D-products

In case you are drawing the profile of your product or tools the cursor keys can be used to give
directly multiples 45 degree angles. e.g.:

a = 135°

V0606, 1.11

a = 45°

a = -90°

a = 90°

- Horizontal or vertical projections for 2D-products

After you entered the length of the line interval you can specify if this line interval is either the
nominal length, horizontal or vertical projection. The given length dimension in the enter field
is the line length L if the drawing cursor is in the concerning line.

Horizontal projection with or key

Vertical projection with or key

L is normal entered line length
V is vertical projected line length
H is horizontal projected line length

It will be noted on the screen if projection is not possible.

1.6. Network

2. Product drawing/Product edit for 2-dimensional products

2.1. Introduction

To start a new product drawing, choose product drawing in the
main menu.

To edit an existing product drawing, choose product edit in the
main menu.

On this page you have to enter first the product number and then the drawing number. The
drawing number may also contain alphanumeric characters, which can be entered with the help
of the function key ‘alphanum’ (S6).

2.a

Product number . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .PN

A name or description of this program. The maximum length is 20 characters.

If an existing product number is entered, a warning appears that this product already exists.
You are asked whether to replace that existing product with the new product or not. If you
choose ‘yes', the existing product is erased. If you choose ‘no', you must enter a new number.

V0606, 2.1

The "±" key prompts a "-" character and the "." key prompts a "/" character in the drawing
number.
If 3D is available on the control, it is first required to confirm whether the drawing program­ming will be effectuated in 2D or 3D. 3D drawing is explained in chapter 3.
After finishing this input you have to enter specific product data. Then you can start drawing
the product.
In the edit mode you also have the possibility to make a copy of the active product. A special
function key ‘copy product’ appears.

After entering the general product data the drawing screen appears. In the upper information
row you will find the information about product number, drawing number and inside/outside
dimensions selection.
You create now the bending profile of the product. First you enter the value of the basic length
of the product. Then you enter the angle of the next side followed by the length of that side.
This procedure continues until the product has the desired profile. A circle indicates the actual
position. With the cursor control keys you move this circle to an other position (angle or
length). During the drawing of the profile of the product the graphical software always dis­plays the product at relative scale.

2.e

For creating the product drawing you have to enter the length of a line and the angle to bend or
you can use the cursorkeys for angles of multiple 45 degrees.

V0606, 2.5

2.2. Delete an angle/line or insert an angle

The function of softkey (S1) depends on the position of the drawing cursor.

- If the cursor is within a line segment, it is possible to insert a new angle to bend, in com­bination with the enter key.

- If the cursor is positioned on a bend, it is possible to delete that bend.

- If the cursor is at an end line of the product, the line can be deleted.

2.3. Precision selection

When the drawing cursor (small circle) is on a line segment, with S2 high precision or closing
dimension can be selected. With S2 these functions will be toggled giving 3 possibilities (high
precision - closing dimension - normal situation).

2.f

- High precision:

At bend sequence computation the backgauge stop position will be chosen to get the highest
possible precision of this line interval.

- Closing dimension:

At bend sequence computation the backgauge stop position will be chosen to get the resulting
tolerances in this line interval.

V0606, 2.6

Example:

Delem

2.g

Line interval marked with the open circle should be, if possible, directly placed between back
stop and the centre of the die.

Notes:

Specifying line intervals with high precision and closing dimensions may result in longer pro­duction time.
Also it will have priority over the "front extend ratio", if that is set to "comply if possible". See
section 2.5.

V0606, 2.7

2.4. Large Radius: Bumping

To make a bend with a large radius, the control uses the bumping method. With this method, a
large radius in a product is obtained by a series of slight bends in succession.

2.h

To program such a bend, you must program the following parameters:
radius = the desired radius
segments = number of segments
The number of bends in this radius is the number of segments plus 1.
The more segments you select, the more bendings will be used to create the programmed
radius within a smaller tolerance. With a high number of segments you will need a smaller V­die opening to be able to bend in a proper way. Which value is acceptable as maximum for the
V-opening of the die is calculated and displayed on the screen.
For the definition of the line lengths to be programmed in the part connected to a bump radius
segment, see figure 2.i.

2.i

Lengths L1 and L2 must be equal or bigger than the radius R.
When you must program such a bend, first program a standard angle with adjacent sides. Then
put the cursor back on the angle and press the function key ‘bumping’ (S2). You will be
prompted to program the radius and the number of segments. After programming these param­eters the radius is drawn in the product and the maximal V-opening which can be used is dis­played on the screen. This is shown in figure 2.j.

V0606, 2.8

Delem

2.j

Specification items:

Radius input:
min. value = 0.1 mm
max. value = 2500.0 mm

In the ‘assignments’ menu, it is possible to modify the way the radius bend is divided into seg­ments. See section 2.5 for more information.

2.5. Assignments

Pressing ‘Assignments’ results in the parameter pages.
If Variants programming is active (indication 'Variants On' in the title bar), a warning is given
that corrections will be lost. Press 'Yes' to proceed with the assignments or 'No' to go back to
the edit screen.
See section 2.8 for more information about variants progamming.

Automatic bend sequence computation works with several criteria in order to find an optimum
between a minimum production time, handling possibilities without product/machine and
product/tool collision.
In order to find one of the optimums you must program several computation parameters with
which the bend sequence can be computed.
Some of these parameters are machine related, axis speeds a.o. and some are related to han­dling possibilities and turn times.
There are three screens with parameters for 2D programming.

X-axis and R-axis positions will be corrected automatically so the plate will rest on the
backgauge finger (0 - 3200.0 mm).
This is only possible if an automatic R-axis is enabled.

2.r

Blank length computation

After postprocessing, the controller calculates the developed length of your product and the
bend allowance.
Important for the developed length calculation and the bend allowance is the inner radius of
the bends.
For each of these computations a correction factor can be programmed (RF and AF).

Radius factor blank length . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .RF=

The computed inner radius is multiplied by this factor to correct the total developed
length of the product. The initial value of RF is 1.

Radius factor X-axis position . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .AF=

The computed inner radius is multiplied by this factor to correct the X-axis position in
order to have a correct product dimension after each specific bend (bend allowance).
This factor can be checked by making a product with just one bend and a certain product
dimension e.g. 100 mm (outer dimension). See figure 2.s.

The controller computes the X-axis position necessary to obtain L=100 as shown in figure 2.s.
The accuracy of the length L is dependent on the material parameters like thickness, strength
and kind of material. In order to have a correction possibility with the radius factor AF you can
optimise this computation.
RF and AF do not influence each other. It is recommended that first you optimise the AF factor

V0606, 2.15

for your product and thereafter find the correct value for the developed length correction RF.

2.s

Minimum Y-axis opening . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .YM=

During postprocessing of the programmed product, the control always computes an opti­mal opening of the pressbeam to handle your product. Here you can program a minimum
required opening. The programmed value is the distance above the speed change point
MUTE.

X-allowance DIN . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .XA =

For the calculation of the developed length and bend-allowance during the postprocess­ing of a graphical 2D product, a Delem formula is used. It is also possible to select the
standard DIN-formula (DIN6935).
0 = Delem formula (OFF).
1 = DIN formula (ON).

Default setting is zero for the Delem formula. Press the key to select the required set­ting.

Equal sized bumping segments enabled. . . . . . . . . . . . . . . . . . . . . . . .EB=

When a product has a radius bend, the segment size is computed from the number of seg­ments, which has been defined by the user. Standard the first and last segment are calcu­lated half the size of the mid segments to obtain a better result. However, it can be a
problem selecting a die suitable to bend these small segments. Therefore the control can
calculate an equal size for all segments. This can be defined with this parameter.
0 = disabled (no equal sizes).
1 = enabled (equal sizes).

Press the key to select the required setting.
When this parameter is set to 1, all segments will have an equal size.
If it is set to 0 the calculation is as before, including half size segments. If in this case a
problem with the size of the V die is detected in the bend sequence menu, the user is
asked whether or not to select a re-calculation with equal size segments.

2.6. Bend sequence

After completion of your drawing, with function key S5 you select the "bend sequence" mode.
You will have to enter the number of the machine lowerside, the die, the machine upperside
and the punch first. This number corresponds with the number in the respective tool libraries
(menu number 7, 8, 9 and 10).
If the number entered is not known, the controller prompts the message "not programmed".
You have to program the machine parts and tools before you can compute the bend sequence.
Programming can be done via the respective selections in the program menu. The several tools

V0606, 2.16

Delem

as available in the respective tool libraries can be shown on the screen with S2 (show library).
This selection will give an overview of the tools including the main properties of each tool.

2.t

If this overview is not sufficient to select a tool, press the function key ‘view’ and the key
‘graph. dir’ to get a graphical overview of available tools.

V0606, 2.17

2.u

In your machine and tool library you can program 10 different machine uppersides, 10 differ­ent machine undersides (tables), 99 different dies and 99 different punches. One of each must
be selected, and can also be changed during the bending sequence determination. These selec­tions are prompted in the lower left corner of the screen. Within the bend sequence screen, the
softkey ‘show library’ will remain available to get a graphical overview of the tool library as
shown above.
After specifying machine part and tools the product and machine will be drawn on the screen.

Note:

A big radius (bumping) is shown during bend sequence computation but is treated as a single
bending.
The CNC-data of the bendings necessary to produce the radius are computed during postpro­cessing.

V0606, 2.20

Delem

The bendsequence computation can be activated from the last bending upwards to the first, but
it is also possible to activate for instance the last 2 bendings manually and to compute the opti­mal bendsequence for the rest of the bendings. This computation will start from the bending
indicated with an asterisk. With this possibility and with help of the swap function you can
compute several possibilities.

During the automatic bendsequence computation you can always
interrupt the computation by pressing "Abort computation".
If the computation is interrupted, the computer will give most of the
times a suggestion for the bendsequence. It is possibly not the most
optimal solution.

When a bendsequence has been determined, a CNC program can be
calculated and stored. This process is called postprocessing. When
postprocessing is finished, the ‘blank length’ of the product is dis­played.

(second row) Open a graphical overview of the bend sequence, in
order to have a visual check.

Move bend

In the graphical overview of the bendsequence, it is possible to change the order of bends sim­ply by moving a bend to another place. Press the button ‘Move bend’ and the number of the
first bend is highlighted. Use the arrow keys to move this cursor to the bend that must be
moved. When the correct bend number is highlighted, press the enter key to select this bend.
Now use the arrow key to move the bend to the right place in the sequence. If the bend is on the
correct place, press 'enter' to confirm.

Swap Bends

With this command, two bends can change place in the bend sequence. Press the ‘swap bends’
button. Move the cursor to one of the required bends and press the ‘swap’ button or press enter.
Then move the cursor to the bend with which it must be swapped and press the enter key or the
‘swap’ button. Now the bends have been swapped. If for any reason the action must be can­celled, press the softkey ‘abort swap’ during the procedure.

• Restoring a bend sequence

A (partly) determined bend sequence is not automatically reset after leaving the bend sequence
menu.
After you re-enter the bend sequence menu it is possible to continue with the existing bend
sequence.

If you re-enter the bend sequence menu you have the following options:

V0606, 2.22

Delem

2.y

‘new’ start new bend sequence, the existing bend sequence is

reset

‘continue’ continue with current bend sequence, the existing (par-

tial) bend sequence is restored and shown on the screen

If you have loaded a drawing from which a postprocessed bending program already exists,
there is a third option when you enter the bend sequence menu:

‘restore’ restore bend sequence from postprocessed program, the

bend sequence is restored from this postprocessed bend­ing program and shown on the screen

If you have drawn a new product in the menu "Product drawing" and you enter the bend
sequence menu for the first time, there is no existing bend sequence and postprocessed pro­gram yet, these previously mentioned selections are not shown.

• Minimum bending length

The minimum possible bending length will be calculated from the V-opening parameter (½ V),
but also depends on the angle to bend and the thickness of the material to be bend, see figure

2.z. If the programmed value for the wanted product does not correspond with the minimum
possible length, you will get a warning message on the screen.

V0606, 2.23

• Machine/Tool selection

At each bend you can select one of the tools or machine shapes which are present in your
library. The displayed number is the number of the tool and machine part which is presently
selected.
Entering a new number will select another tool or machine part which will be drawn directly
on the screen.
With the "enter" key you can toggle between punch-, die-, machine upper- and lower part num­ber.
It is also possible to turn the punch and die with respect to the machine shapes. To achieve this,
the tool number must be programmed negative.

2.aa

In order to get a graphical overview of the available tools while you are in the bend sequence
menu, press the function key 'show library' (S2). If pressed, an overview appears of available
tools.
Which type of tools is shown depends on which type was prompted in the bend sequence
screen: punch, die, machine upper- or lowerside.

• Bend sequence computation

With ‘compute’ the bend sequence can be computed automatically.
The computation is done only with one set of tools. These are the tools selected at the last
bend.
The computation of the bend sequence starts always at the bend which is indicated with the *
at the lower left corner of the screen.

Example: Product with 7 bends

2.ac

In the first example the bend no. 7 and no. 6 are chosen manually, from 5 up to 1 thereafter are

V0606, 2.27

computed automatically.
In the second example the complete bend sequence is computed (7 up to 1).
During the computation all assignments are important so you must be sure before starting the
bend order computation that all assignments are set correctly.

•Store

After you have completed the bend sequence a CNC-program can be generated. This generated
program will be stored in the controller program memory.

2.7. Variants programming

The term ‘Variants programming’ means that the operator can make modifications to an exist­ing program in the graphic menu, without having to build a new CNC program from scratch.
An existing program can be altered without loss of existing corrections and bendsequence. If
such an existing program contains proper axis values and product positions then this informa­tion can stay intact, only the latest changes (angle, sheet length) are recalculated and entered
into the program.
For instance, when a side length has been altered in the graphical bend overview and the
‘store’ command is given, then a question appears how to compute a CNC program.

2.ad

When update (S4) is chosen, the existing CNC program is changed with regard to modified
values (angle, length), but other values of bend parameters stay the same. The expression ‘re­use corrections’ refers to the corrections that may have been entered in one of the production
modes. These production modes are explained in chapter 10.
When new (S5) is chosen, a new CNC program is calculated. Corrections in the existing CNC

V0606, 2.28

Delem

program are lost.

In order to keep the existing program, check that the indication ‘Variants On’ remains in the
title bar. When you start an action or command that would seriously change the program, a
warning is issued by the control:

2.ae

If you choose 'yes' (S4), the indication 'Variants On' will disappear from the title bar. This
means that the next time when a new 'postprocess' command is started, a new CNC program is
built and old corrections will be lost. When 'No' (S5) is chosen, the action is cancelled and
'Variants on' remains.
The message "CNC program and corrections will be lost" is not literally true. The CNC pro­gram is still present, but it cannot be updated anymore from the graphical menu. If the old
CNC program must be stored, it is still possible to go to ‘data edit’ mode and store the program
under a different product number.

Connect . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .CN

The parameter "connect" is to have a possibility to connect certain programs to one
another. This option can be used to produce 3-dimensional products.

• Connecting CNC programs

With the parameter Connect it is possible to create a 3-dimensional product. The control auto­matically executes the bend sequences in the different directions in succession. You program
the control as follows:

Instruction for 3-dimensional product programming (9 steps)

1 Create the product in one direction.
2 Create the product in the other direction.

There are now two bendprograms of one product in two directions. You connect these pro­grams as follows:

3 Select the program with the bendsequence in the direction which you want to execute in

the first place. You select the program of the product via menu 3, product selection.

4 Go to menu 2, data editing. Select the parameter CONNECT. Enter the program number

of the product in the other direction.

5 Select the second program as in step 3. Repeat step 4. If you want to connect two pro-

grams, as in this example, you enter the program number of the first program. The cycle
is closed.

When you want to execute more than two programs in succession (not necessarily to create a
3-dimensional product) the second program must refer to the third. The third program to the
fourth and so on. The final program of the cycle must always refer to the first program.

To produce products with connected programs the next four actions are necessary.

6 Select the first program
7 Select the Automatic mode
8 Program the amount of products you want to produce with the ‘stock count’ parameter.
9 Push the Start key.

When the first program has been finished the second program starts automatically. The pro­gram counter indicates the remaining amount of repeats.

assumes the bottom of the die as required Y­axis position.

V0606, 4.7

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 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 'flattening offset'.

flattening and
bottoming

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 depend­ing on the working tonnage. If however the force is sufficient for the beam to go to the calcu­lated Y-axis end of bend position, the beam stroke will be limited by the position value.

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.

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.

Bend position . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Y

The required Y-axis position for this bend. This parameter only appears if absolute pro­gramming 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 posi­tive 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.

V0606, 4.8

Delem

Backgauge position. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .X

Backgauge position. When a negative sign is programmed this backgauge dimension is
an incremental dimension. The incremental dimension is subtracted from the actual X­axis position. Therefore this parameter can also be used as a chaining measure.

Only in case you have a configuration with a R-axis.

The function key (‘gauge func’) appears when you put the cursor bar on this X-axis parameter.

4.e

If you press ‘gauge func’ a window appears with three programmable parameters.

4.f

Gauge pos. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . GP

With this function you can program another ‘gauge position’ for this specific bend. The

V0606, 4.9

gauge position (parameter GP) you can program depends on the backgauge dimensions.
Backgauge dimensions are programmed in the menu ‘program constants’.
Default gauge position = 0 (no lay on)
Other possibilities are:
gauge position = 1, lay on first level
gauge position = 2, lay on second level (only possible when number of gauge positions
(GN) = 3)
gauge position = 3, lay on third level (only possible when number of gauge positions
(GN) =4)
When you program another ‘Gauge position’ the backgauge position changes, but the
gauge position for the plate does not change. This means that the next two parameters
‘R-finger position’ and ‘X-finger position’ remain the same. See also example below.

4.g

R-finger position. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .R

Default value = the height (R direction) of the gauge position of the plate. This value can
manually be adjusted in this window, if required.

X-finger position. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .X

Default value = the value in X-direction of the gauge position for the plate. This value
can manually be adjusted in this window, if required.
With ‘END’ you leave the window and the new values have been saved. If you press
‘cancel’ you leave the window without changes.
When you have changed the ‘Gauge position’ then the axes positions in X- and R-direc­tion have also been changed. Therefore the parameters ‘backgauge position...X’ and ‘R-

axis....R’ have been changed. The new values depend on the dimensions of the back-

gauge finger which you have programmed in the menu ‘program constants’. When you
have changed the values of ‘R-finger position’ and ‘X-finger position’, then these
changes are also included.

Retract. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .DX

ters active).

1 = Step change at muting position when the beam moves in opening direction.

2 = Step change at upper dead point.

3 = Step change at upper dead point without movement of any axis and the control goes
to "stop".

4 = Step change if C-input signal becomes active, without movement of the beam. When
you still have a beam movement there will be no retract function of the backgauge per­formed. See also code 5.

5 = Step change if C-input signal becomes active and the beam is in the upper dead point.
Now you may move the beam and the retract function of the backgauge will be per­formed.

10= Step change at end of decompression with the Y-axis beam waiting at the pinching
point until the backgauge is at the retract position.

11= Step change at mute position when the beam moves in the opening direction, with
the Y-axis beam waiting at the pinching point until the backgauge is at the retract posi­tion.

12= Step change at upper dead point, with the Y-axis beam waiting at the pinching point
until the backgauge is at the retract position.

13= Step change at upper dead point without movement of any axis. The Y-axis beam
will wait at the sheet clamp point until the backgauge is at the retract position. After the
bending with this code, the control goes to "stop".

15= Step change if C-input signal becomes active and the beam is in the upper dead
point. The beam may be moved but not necessarily. The Y-axis beam will wait at the
sheet clamp point until the backgauge is at the retract position.

The not mentioned CX-values have no meaning.

The rank number of this angle, when counted from left to right through the product pro­file (figure 4.j). The digit before the dot describes this rank number, the digit after the dot
descibes the rank number of this bend in case of a bumping sequence.
In case of a normal angle, the bumping number should always be 1. In the case of a
radius bend, all bends in the bumping sequence should have the same angle number but a
different bumping number. Programming a radius bend in this manner will allow for
bumping correction in the production mode.

A backgauge number refers to a certain spot of the product, that can be placed against the
backgauge during bending. Such a spot is either a product end or an angle. The back­gauge numbers in the product are counted from left to right, starting with 0 (see figure

4.k). For each bend you must program here which spot must be placed against the back­stop. If the plate must rest on the backgauge finger, add 100 to the XN value. For each
next lay-on position, add another 100 to the backgauge value (200, 300, etc.).

• Slave axes

Depending on machine settings, it is possible that an auxiliary axis is accompanied by one or
more slave axes that can be programmed individually.
By default, each slave axis follows the position of its master. To progam a different position for
a slave axis, move the cursor to the required axis. The softkey ‘show slaves’ (S7) will appear.
After pressing this key, a new pop-up window appears in which the values of the axis and its
slaves are shown.

4.n

Each slave can be programmed with a different value. If no values are programmed, the slaves
will follow the master. Furthermore, the same minimum and maximum values apply for the
slaves as for the master axis.
This pop-up window is also activated when you move the cursor to an axis parameter and you
type a new value. When this new value is different from the value of the slave(s), the control

V0606, 4.16

Delem

will prompt a warning:
"Value will be copied to slave axes. Are you sure?"
If you choose 'yes', the values are copied to the slaves. If you choose 'no', the pop-up window
will be opened automatically. Once you have accepted this copy action with ‘yes’, the value
will be copied to the slaves automatically in the future.
Press END to leave this window.

• List of bendings of the prepared program

Pressing this softkey in the data editing mode will result in a complete overview of the bend­ings programmed. After pushing END the page will be restored from which this page was

the arrow key to move to the right place in the sequence. When the correct bend number is
highlighted, press ‘move bend’. The bend will be inserted on the current place.

Swap bends

With this command, two bends can change place in the bend sequence. Move the cursor to one
of the required bends and press the ‘mark bend’ button. Then move the cursor to the bend with
which it must be swapped and press ‘swap bends’. If for any reason the action must be can­celled, press the softkey ‘abort mark’ during the procedure.

A bend is no longer marked when the mark is aborted, when an action is finished or when this
menu is left.

• Ending data preparation/data editing

After pushing the END key in the Data edit screen, a new page with product number and draw­ing number appears.

4.p

At this page the program number and the drawing number must be given to the new prepared
program, or can be changed in the edit mode.
If either way the number is changed into an existing product number, a warning appears that
this product already exists. You are asked whether to replace that existing product with the new
product or not. If you press ‘yes’ (S4), the existing product is replaced by the current product.
If you press ‘no’ (S5), you have to enter a new number.
After typing the product number, press ‘enter’ to confirm it and to return to the main menu.

4.3. Special edit function

When a new program has been made and several tests are required, the operator can switch
from "editing"-mode directly to the "auto"-mode and vice versa by pressing the particular
mode buttons.
When in "data editing" a specific bending is selected, the operator can now select the "auto­matic mode" or "step by step mode".
In case one wants to edit the program, the edit mode can be selected directly with the program­ming key. In this way many key operations are saved in order to make program changes
quickly.

Note:

This special edit function can not be used with connected programs.

4.4. Edit notes

After changing program data in the menu ‘Data edit’ the control will not automatically calcu­late:

1Force
2 Decompression
3 Crowning device setting
4 Z-axis position offset
5 X-axis position correction

Parameters 1 through 4 are only automatically recalculated if the parameter Auto computa-
tions edit (see the menu ‘program constants’) has been activated (value = 1).
Parameter 5 is only automatically recalculated if the parameter Bend allowance (see the menu
‘program constants’) has been activated (value =1). Additional corrections on the X-axis posi­tion can be made with the parameter corr.X (per bend) and G-corr.X (for all the bends of the
active program) in the automatic and step-by-step mode.
For detailed information upon both parameters see the chapter about Automatic mode and
Step-by-step mode.
There is one exception: when the parameter bendmethod is changed the “force” and “Decom­pression” will be adjusted automatically.
Also you may find that the graphical simulation will not go properly when you have changed
tools and/or X-axis dimensions.

The programmable height is used to calculate the Y-axis value in case of "flattening". The
default-value for this parameter is the standard tool height, which is already programmed.
Every time that this standard height is changed, the flattening height will be made equal to this
tool height (due to safety reasons). See figure 6.g.

The total toolheight will be used to calculate the speed change point mute and the flattening
height will be used to calculate the end position of the Y-axis beam to flatten the product. The

Before starting drawing the machine shape upper or lower side you must enter the press-beam
height of the upper part when the moving part of the upper side is in its mechanical top dead
centre.

6.5. Saving/loading of tools

With the function key 'backup' (in any of the tool menus) the dialogue 'Save Punches' is
opened. From this menu, it is possible to save tools to a back-up location. This procedure
works the same for all tools and machine shapes and regardless of the back-up location (floppy
disk, network).
When the function key 'backup' has been pressed, a screen like shown below should appear.

6.w

At the top of the screen, the back-up location is shown. If this location is not correct, you can
change the subdirectory with the softkey 'backup directory'.
To save a tool, enter its number from the list and press 'enter'.

Function keys:

all Save all tools.

backup

Change, make or remove a subdirectory where tools will
be saved.

V0606, 6.19

Function keys:

view Button to select one out of two possible viewing modes:

- graph. dir.

For backup operations, it is possible to make use of subdirectories. Subdirectories can be cre­ated in this menu. When the softkey 'backup directory' is pressed, a new window appears with
a list of available back-up directories. A selected directory can contain products and tools, so
each user can keep his own set of products and tools, if necessary.

6.x

You can make new subdirectories or delete existing ones with the softkeys 'make subdir' and
'remove subdir'. If there are subdirectories present, use the arrow keys to scroll to the required
directory and presss 'enter' to select it.

Function keys:

make sub­dir

remove
subdir

V0606, 6.20

Add a new subdirectory. The name of the subdirectory
can be any alpha numeric string of maximal 8 characters.
Avoid the use of slashes ('/')

Delete a subdirectory. If the subdirectory is not empty the
controller returns the message 'unable to remove direc­tory'.

Delem

The 'load tools' procedure is different from the 'save tools' procedure. When you select 'load
tools' the control checks if the toolnumber already exists in the control. If not, then the tool is
automatically copied from disk to the control. If the toolnumber already exists then you have
three options:

-cancel (S3), the toolnumber is not loaded.

-overwrite (S4), the tool in the control is replaced by the tool from disk.

-rename (S5), the tool number of the tool on the disk is first renamed before it is loaded from
disk.
This means (in case of rename) that a new toolnumber is proposed. This new toolnumber is the
first free tool number in the tool library. Accept the proposed tool number with the enter key or
enter the number of another free tool number and press the enter key.

6.y

Note:

Tools are linked to the control by their machine number. When a 'restore' operation is started,
the control will only show those tools, which have the same machine number as the control.
If for any reason the machine number is changed, a new tool back-up operation should be exe­cuted to save the control tools with their new machine number.
