Material thickness

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 6 USER GUIDE DNC 600S

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.

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 1 when 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.

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 Appendix F: Programming with L-Alpha on page 38.

DIRECT PROGRAMMING

Programming Example

The following product is to be realized:

Th: 2.0 mm

Lmat: 1000 mm

The bending order is the following:

PAGE 12 USER GUIDE DNC 600S

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.

Place the cursor in the N field (reminder: + to position the cursor on the top of the page).

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 71).

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 searchs 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.

Caution: 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 original 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:	Caution, 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 21).
