2.1 Graphical programming

From the main menu you can select one of the programming

possibilities.

In order to design or edit a new product in Menu selection 1 or 2, the bendcalculation option (OP-BCAL) must be installed. This option allows fast and simple programming with your DA-58.

The graphical programming option "OP-BCAL" is based upon the

"PROFILE" software. "PROFILE" is a complete product design tool that allows you to

draw the profile of your product. "PROFILE" 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.

"PROFILE" provides you to select the most optimal bending sequence either to obtain minimum production time or manipulation possibilities of your product.

Features of the "PROFILE" design tool are:

* Graphical design of product shapes * Auto scaling * Horizontal and vertical projected dimensions can be entered * Blank length computation * Real scale tool design * 100 different machines memory each with 10 different upper side

shapes and 10 different under side shapes (tables) * Changing of length and angles * Bumping (big radius) * Adding or deleting of angles * Existing products can be copied, changed and be stored as a

new product * Product time indication * Closing dimension or highest precision tolerance selection * Connecting programs for 3D - production

"PROFILE" 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

- 11

Postprocessing of drawings

The postprocess facility computes:

* Fully automatic * Machine adjustment such as: - Y-axis valve

- Decompression

- X-axis position

- X-axis retract

- Y-opening

- R-axes

- Z-axes

2.2. Product drawing / Product

With Menu selection 1 you can draw a new product. With Menu selection 2 you can make changes in an existing product. After selecting 1 in the program menu you will have page 1.1 on the VDU/screen. All input data can be found in the enter field in the lower left corner of the screen. On this page you have to enter first the product number and then the drawing number. This

last input can be alphanumeric and depending on which letter, you have to press first S4 or S5. The "±" key prompts a "/" character and the "." key prompts a "-" character in the drawing number.

After finishing this input you will get page 1.2 on which you have to enter specific product data. You can start drawing the product on page 1.3.

Selecting the edit mode in the program menu, you will get page

2.3 giving the drawing of the existing product. Via softkey S2 you can go backwards to page 2.2 for changing the product data like in page 1.2.

Fig. 2.2.b

On these pages you can program/change the thickness, kind of material and length in the Z-dimension of your product. Every

input must be finished by pressing the enter-key. Also you must specify whether the dimensions of your drawing will be inner or outer dimensions. The definition about inner (B) and outer dimensions (A) is given in figure 2.2.c

Fig. 2.2.C Inner/outer dimensions

- 13 -

On page 1.3/2.3 you can create/change the product drawing. In the upper information row you will find the information about product number, drawing number and inside/outside dimensions selection.

Fig. 2.2.d

For creating the product drawing you have to enter the length of a line and the angle to bend in figures or with help of the drawing cursor for angles of multiple 45 degrees.

2.2.1. Control keys

The drawing software uses several function keys on the

front panel.

* S1 thru 6 * Drawing cursor control with:

* Horizontal projection definition of entered length

with the key.

* Vertical projection definition of entered length

with the key.

* Zoom function: Enlargement

Reducement

Drawing cursor control

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.:

- 15 -

Horizontal or vertical projections

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.

Fig. 2.2.e

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.

Zoomfunction:

The zoomfunction is only active in the simulation drawing.

2.2.2 Delete of an angle/line or insertion of an angle (S1)

The function of this softkey is depending 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.

- If the cursor is positioned on an angle, it is possible to

delete that angle.

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

deleted.

2.2.3 Precision selection (S2)

When the drawing cursor (small circle) is in 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)

- High precision (marked green) : At bend sequence computation the backgauge stop

position will be chosen to get the highest possible precision of this line interval.

- Closing dimension (marked red) :

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

Example:

18 -

Line interval marked with the open circle is never 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 selected to "comply if possible".

- 19 -

2.2.4 Big Radius (Bumping)

When the cursor is on an angle you can select a big radius by pressing function key S2. After pressing S2 you are prompted to program the following parameters.

radius = the desired radius in mm tolerance = the allowed tolerance in mm

A smaller tolerance will result in more bendings necessary to

realize the radius. The V-die opening which must be used to realize the big radius is decreasing when a smaller tolerance is specified. For the tolerance definition see figure 2.2.4.a.

Fig. 2.2.4.a

For the definition of the line lengths to be programmed in the part connected to a bump radius segment, see figure 2.2.4.b.

Fig. 2.2.4.b

Lengths L1 and L2 must be equal or bigger than the radius R. After programming these parameters the radius is drawn in the product and the maximal V-die opening which can be used is displayed on the screen. When the cursor is on a radius and S2 is pressed again the radius will be deleted and changed back to a single angle (toggle

function). For the screen information see figure 2.2.4.C

2.2.5 Product data (S3)

Pressing S3 results in the product data overview of page 1.2/2.2.

On that page you can return to the drawing again via softkey S6.

2.2.6 Assignments (S4)

Pressing S4 on page 1.3/2.3 results in the parameter pages starting on page 1.5/2.5.

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.

Page 1.5/2.5 gives the first page of these assignments.

Fig. 2.2.6.a

parameter explication (paqe 1.5/2.5)

OPTIMALISATION DEGREE OD= Range 1-5

The number of alternative sequences to be computed for each bending must be entered here.

The higher this number the more alternatives are to be

examined by the processor, so the longer the computing

time will take.

X-AXIS SPEED BS=

Speed of the backgauge of your press brake

R-AXIS SPEED RS=

Speed of the R-axis fingers

FRONT EXTEND RATIO .... FR=

This is the ratio of the minimum allowable length of your

product which extends in front of the press to the total blank length of the product. You must have a minimum length of your product in front of the press to be able to handle the product. Max. possible value = .49

FRONT EXTEND RATIO ACCEPT ....FA*

- In case programmed 0 (comply if possible) : This means that when possible the computer tries to comply

to the front extend ratio and only when this will result

in no solutions to be found it will accept that the length in front is smaller than the specified ratio.

- In case programmed 1 (comply always) :

The computer will always comply to the front extend ratio. This may result in no solutions to be found.
