This page makes it possible to quickly programme a bend, and/or briefly stop production to perform a single bend without modifying or losing data in the production programme.

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 L of the wing (external measurement) and the position of the X gauge will be calculated automatically.

or

directly enter the distance at which the X L gauge is to be positioned.

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),

o the retraction of the gauge,

o the reduction in bending speed, o slow lifting, etc.

PAGE EASY BEND

PAGE 5

Press the START button or the pedal and the axes will position to the desired values. The numerical command will automatically go into semiautomatic 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.

EXPLANATION OF THE FIELDS

See Explanation of the fields page 8.

PAGE 6 USER GUIDE DU 6000

CREATING A PRODUCT

This paragraph explains how to programme a product as well as the method

for correcting and recording it.

THE SEQUENCE PAGE

This page displays all the bending information 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 centre).

However he must avoid directly modifying the Y and X values calculated by

the DNC.

If modifications should be necessary for these axes, the correction page has

to be used.

Hint

An operator can directly programme a product in this page, without "pass-

ing" through the L-alpha page and definition of the bending order.

This simplifies the manipulations a great deal, since all the information re-

quired for the bending are on this page.

To change from one sequence to another, press the

When the last sequence of the program is reached, the small LED of the

key lights up. At this moment, when pressing the key, a new sequence is created with the same contents as the last sequence. A message COPIED is displayed.

On this page, 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 machine parameters.

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.

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.

Q	Number of product sequence repetitions. Quan-
	tity 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 pro-
	grammed, the beam doesn't stop at the CP. No
	retraction.
	If value 0 is introduced, the beam stops at the
	CP, 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 CP and waits till the
	retraction is made, in order to carry out the
	bend.
	1 = the beam stops at the CP, then continues
	immediately, at the same time as the retrac-
	tion is carrying out.
Ext start	If nothing is programmed in this field, the axes
	start automatically from the BDC, from the CP
	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 con-
	structor.
	- In most of the configurations, it will be suffi-
	cient to give a down command. At this com-
	mand, the axes take position, then a second
	down command has to be given, in order to
	move the beam.

PAGE 10 USER GUIDE DU 6000

PROGRAMMING ON 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 faster

Direct programming.

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 development

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 chapter Annex F: Programming with L-alpha on page 37

DIRECT PROGRAMMING

Programming example

The following product is to be realized:

Th: 2.0 mm

Lmat: 1000 mm

The bending order is the following:

CREATING A PRODUCT

Bend 1 on FACE 1 and LEG 0

Bend 2 on FACE 3 and LEG 4

Bend 3 on FACE 2 and LEG 3

Clear the memory	Call the sequence page with the				key.
	Clear the work memory.

In the event of the removal of a product, the data contained in the Tools fields, the Thickness field and the Material Information fields remain (if displayed). This avoids the operator having to reprogramme unchanged data.

The following working method is recommended: Programme or call the product.

Switch to semi-automatic mode. Execute first bend.

Measure the result.

Switch to programming mode.

Enter the measured angle into the COR field (see above). The DNC automatically calculates the corrections to be made to Y1 and Y2.

If necessary, make the corrections to the gauge axes.

Bend a second product on the first bend to check the corrections.

Move to the following sequence and then proceed in the same way for all subsequent sequences.

When all the bends are correct, switch to automatic mode and proceed normally.

The correction entered above is applied only to the current sequence. Every other sequence must be corrected individually.

Product-by-product correction is possible in the CORRECTION page (see explanation on page 68).

The upper part of the screen displays the number of the product currently in the work memory as well as the number of the drawing of that product.

The DNC also displays the number of sequences programmed, as well as the number of sequences still available in the internal memory.

Then are displayed, in ascending order, the numbers of all the products stored in the internal memory.

The NEW_P field enables the operator to create a new product directly, starting from this page.

Position the cursor on NEW_P and press the key.

This page allows to display a list of searched products according to one or more criteria like the code number, the thickness, the bending length and/or the unfolded length.

Under the heading --CRITERIA-- are displayed the different criteria according to which it is possible to search for a product.

These criteria can be combined, that is it is possible, for example, to ask for the list of all the products stored using a specific tool pair and having a particular material thickness.

The products meeting the defined selection criteria are displayed on the second half of the screen.

To make a search by criteria, proceed as follows:

Introduce one or more selection criteria in the fields provided.

Press .

If the list contains 7 or more products, the following page or pages can be displayed by pressing .

CALLING A PRODUCT

This operation seeks a product in the internal memory and place it into the work memory.

Calling a product is possible from all pages on which the cursor can be placed on the P or CODE field.

Attention: The called product "erases" the product already in the work memory. Pay attention to save, if necessary, the current product before calling another product.

Introduce the product number in the P field or the code number in the CODE field.

Leave the cursor on the field which has been programmed just now.

Press				.
The product requested is then copied into the work memory (the origi-
nal of this product is, of course, conserved in the internal memory).

SAVING A PRODUCT

This operation is used to permanently save a product located in the work memory.

Saving a product is possible from all pages on which the cursor can be placed on the P field.

It should be noted that after saving the product remains present in the work memory.

To save a product proceed as follows:

If you wish to give a drawing number or name to the product, fill in the CODE field. This operation is optional.

Enter the number of the product in the P field. Leave the cursor in the P field.

	Press the				key.
	If the system displays the message EXISTS, choose another number.
	If you wish to save a product under a number which already exists (e.g. after
	modifying a product), the product bearing that number must first be deleted
	in the internal memory.
NB:	Attention, the N° 998 and 999 are reserved for special functions.
	998 for the temporary storage of the work memory contents during PC
	<-> DNC transfer.
	999 for total deletion of the internal memory (see page 20).

DELETING A PRODUCT

Call the list of products page.

Place the cursor on the P field and introduce the number of the product to be deleted.

Press .

It should be noted that this action has no effect on the internal memory.

	ory without the possibility to cancel this command.
	Call the list of products page.
	Introduce the value 999 in the P field.
	Press	.
