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

Pressing once will display the page in large characters, pressing twice will display all dimensions and functions of the current sequence in small characters.

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 1 is 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.

PROGRAMMING WITH THE SEQUENCE PAGE

In this guide, it is considered that the DNC is configured so as to be operational (i.e. machine and tool parameters programmed).

The operator has 2 methods available for programming.

The fastest

Direct programming (or programming in the sequence page)

Direct programming is the faster method for an experienced operator, because all the programming of the product is done on the same page. This makes it possible to programme the positions of the axes directly, and it calculates the depth of bending according to the angle entered.

With calculation of the flat pattern

The L-Alpha method.

The L-alpha method makes it possible to enter a profile to bend with the external dimensions and angle of each face. The DNC will calculate the developed length: After having programmed the sequence of bends, the DNC will calculate the position of the gauges. Explanation of this method in page 38.

WORKING MODES

Programming mode Allows to introduce, modify and read data as well as to store, search for and transfer programs.

Manual mode Authorizes axis movement and auxiliary

functions using the keys.

Semi-automatic mode Allows a machine cycle with the current sequence values without automatic sequence change. This mode is used for adjustments when realizing the first product, as well as for products with only one bend.

The sequence change is made using the

keys.

NB: The product counter Q does not function

in this mode.

Automatic mode Normal mode for product production. The DNC automatically changes sequence after each bend. Changing directly from "programming" mode automatically forces the first sequence of the program. Changing from "programming " mode to "semi-automatic" mode and then to "automatic" mode, conserves the current sequence for execution. This allows to take up again a product in production without having to make "empty" cycles.

Sensitive mode

Automatic mode

These modes are independent of the DNC be combined. Exception: the adjustment mode.

ADJUSTMENT MODE

This mode only functions with the DNC in mode. If this is not the case, the press refuses to descend. In this mode the table only functions in bending speed with the pressure and

speed programmed in the current sequence. The top dead center of the current sequence is active, it is thus not possible to

raise the beam above this point. On the other hand, the bottom dead center programmed in the sequence is not

active. Thus only stopping the descent command, or a mechanical stop (punch in the die), or the lower limit switch will stop the beam in the descent phase.

modes and can

PAGE 32 USER GUIDE DNC 600S

SENSITIVE MODE

DNC in Mode

The functioning is identical to adjustment mode, except that the return to the TDC is made in one movement.

DNC in or Mode

The press works in the conventional way, that is:

 High speed approach  Deceleration  Safety stop (if the mode requires it)  Bending  Bottom dead center

It is at the bottom dead center (BDC) that the differences appear. The DNC remains under pressure at the bottom dead center until the descent

command disappears, and this indifferently to the dwell time at BDC. When the descent command is suppressed, the DNC remains at the BDC

without pressure or descent command, until reception of a rise command which it executes immediately.

AUTOMATIC MODE

This mode functions in a similar way to sensitive mode, except that the raising of the beam is made automatically once the dwell time programmed in the current sequence has elapsed.

This even if the descent command remains active.

NB: In all these modes the ascent command has priority. It is executed

immediately on its reception.

APPENDIX F: PROGRAMMING WITH L-ALPHA

In this manual, it is being assumed that the DNC is configurated in such a way to be operational (i.e. the tools and machine parameters have already been programmed).

2 programming methods are accessible by the operator.

The L-alpha method allows to enter a profile to be bended with the external dimensions and angles of each face. The DNC calculates the unfolded length. After having programmed the bending order, the DNC will calculate the stop positions.

Before starting to program a product, make sure that the tools necessary to make the product exist in the DNC memory and write down the numbers of the punches and dies to be used.

To do this proceed as described below: If you are already familiar with the tools present in the DNC, you may go directly to

Bending angle. Allows, for a given bend, to define a special

tooling pair different from the one specified for the product.

If the adjacent field CR (step bending) is

empty, when the field indicates the internal bending radius calculated taking into account the angle, the material and the tools.

The operator can enter the value of the internal radius which he considers to be correct, then introduce the value 1 in the CR field.

During the calculation, the TOL (tolerance)

key is pressed, the ri

field indicates the distance defined according to the TOL explication below.

When performing step bending, this field indicates the theoretical radius requested by the operator. (See Ideal Curve, page 67).

TOL

Number of bends requested when working with step bending. (See Ideal Curve, page 67). This number must be between 3 and 99. The value 2 makes it impossible to change modes.

Note: This number must be such that the

length of the step bend segments are greater than half the length of the die V opening.

Tolerance. If the value in the CR field is equal to 1, the tolerance indicates the value according to the illustration below.

R1 = Bending radius introduced by the operator.

ri = Bending radius calculated by the system. If the value in the CR field lies between 4 and

99, indicates the difference between the chord formed by two bends and the arc of the theoretical circle, that is the difference between the theoretical radius ri and the apex A of the chord.

ri = Theoretical bending radius requested by the operator. A = Apex.

PAGE 56 USER GUIDE DNC 600S

TOOL REFERENCE

The machine has been adjusted according to the following principle: When, theoretically, the punch's leg face on the beam is in contact with the

surface of the table, the value of the Y1 and Y2 counters is 000.00. In practice this adjustment is made using two calibrated blocks, whose value

has been introduced into the counters. Definition:

The reference value (REF Y) is theoretically the sum of the heights of both tools; punch and die.

The height of the punch is the distance between the "point" of the punch an its leg face on the beam.

The precision of all bends realized by the machine depends on the reference value REF Y.

The numerical control calculates the bending depth using:

 the REF Y value,  the geometrical values of the tools,  the sheet metal thickness.

If the resulting bends differ greatly from the programmed value, the reference and the values above must be controlled.

APPENDIX G: MISCELLANEAOUS PAGE 57

To control the reference, simply, in on the flat of the die (be careful with the pressure of the active sequence) and read the value indicated by the POS Y1 and Y2 counters.

This value must be identical, for both counters and also correspond to the REF Y reference value displayed on the PUNCH / DIE PROGRAMMING page.

If it is not possible to move the die to obtain a situation as shown possible using a die with a small opening, to place on the die a thick sheet (which will not bend under the weight of the beam) or blocks of a know precise thickness, (see figure below).

The value of the material introduced between the punch and the die mu then be subtracted to obtain the reference value REF Y.

In the latter case, you must contact the manufacturer.

Y1 and Y2 Counters Identical, but Different from REF

If the difference between the counters Y1 and Y2 is within the acceptable tolerance, but the Y1-Y2 value is greatly different from the REF Y value, you must determine if the difference comes from the height of the die or that of the punch.

In this case the tool at fault must be corrected so that the REF Y result is identical to the value of the Y1 Y2 counters.

PINCH POINT

Definition

The pinch point (contact point) is the position of the beam which corresponds to the moment when the point of the punch makes contact with the sheet metal placed in the die.

This point is not programmable, but is calculated by the DNC using the REF Y value and the sheet thickness.

The position is determined by the following PP = REF Y + Th (sheet thickness). The PP is used by the DNC cycle to maintain the s

) the sheet is not pinched during X backgauge retraction

b) the sheet is bent too much during X backgauge retraction

To remedy these problems you must:

For the softwares having the "PP correction" parameter, if the reference, the tooling dimensions and material thickness are correct you can modify this parameter in order to correct the PP (adjustment of the material clamping) without interfering with the other points.

CYBACK

For this program, the RS cable must be connected on the RS232 port of the J5 plug. The transmission parameters must be programmed on the DNC with the same values as for the test of the serial ports (see paragraph above). These same values must be programmed on the PC.

If the transmission runs at 4800 baud, you can try to increase the transmission speed at 9600 baud. The RS 232 norm gives as limit 15 m. By using a more important distance, there is a risk of bad transmission and it will be necessary to diminue the transmission speed.

Reminder: The transmission command can be given only from the PC side.

To permit the serial transmission with CYBACK: Pass to programming mode.

Programming mode From this instant on, the DNC can receive data sent from the PC, provided

that the DNC is in programming mode. In the other modes (auto, semi-auto or manual) the DNC doesn't respond, the transmission is not accepted. During the transmission the operator can leave the DNC on any page. It is not necessary to display the transfer page.

The transfer mode remains memorized, even if the DNC is disconnected from power supply. It has to be re-programmed if the mode has been changed (for instance FLASH).

When passing to a higher, not authorized level, a password modification will be requested. When the password has been introduced, you can "navigate" levels inferior or equal to the authorized one without reintroducing the password. Passing to level 0 resets password validity.

Users A number of different users are predefined. A user is not a physical person in

particular, but can be e.g. all the operators having the authorization to work on the machine. Each predefined user possesses his own password and a maximum level which he can reach. See further under Table of users, access and passwords.

Password Certain users can modify their own password. For the others, the password

can only be changed by a user having a superior access.

Loss of the password In case of loss of the password, a user of a superior level has to reprogram
