Graphic program entry (Options feature)

Proceed in the following way to enter a new graphic program:

 press ;

 press[ New graphic];

General data entry A window is opened where the general data of the program can be entered:

Access to the drawing function will not be allowed unless these data are entered.

• Enter the width of the metal plate to bend;

• enter the thickness of the metal plate to bend;

• enter the strength  of the material to bend, bearing the following convention in mind:

− aluminium: 0 - 30;

− metal plate: 31 - 50 (ideal value 42);

− stainless steel: over 50;

• thematerialis automatically calculated depending on the strength;

• enter the work station if several stations are defined;

• enter the die to be used for the bend ( the die must already have been drawn);

• enter the Die direction (0 = standard, 1 = turned through 180°);

• enter the die cavity to be used for the bend (a die can have several cavities. Enter 1 if it only has one);

• enter the punch to be used for the bend (the punch must have already been drawn);

• enter the Punch direction (0 = standard, 1 = turned through 180°);

• enter a Comment if required.

• move to the [Confirm] button and press [ENTER].

Drawing window The drawing window of the workpiece will be opened and the workpiece produced by means of the drawing function.

The window on the left is the drawing window.

The four windows on the right and drawing data entry windows and respectively represent:

1) The polar drawing data 2) The Cartesian drawing data 3) The roller-levelling drawing data 4) The pressed bend drawing data

How to draw a workpiece

Supposing that the workpiece shown in the figure must be drawn:

20.0   70.0 30.0

 Figure 2.8 - Example of drawn workpiece

The cursor will be in field 1 of the polar drawing data entry window:

• enter the length corresponding to the first section of the workpiece (20.0) in field 1;

•  press[ENTER];

• enter the value of the first angle (120.0°) in field ^α (value of the angle in relation to the next section);

•  press [ENTER]. The next section will be drawn in automatic mode. The section to which the data refer will be marked;

• enter the length corresponding to the second section of the workpiece (45.0) in field 1 (length of the section);

•  press[ENTER];

• enter the value of the second angle (-120.0°) in field ^α  (value of the angle in relation to the next section);

•  press [ENTER]. The next section will be drawn in automatic mode. The section to which the data refer will be marked;

• enter the length corresponding to the third section of the workpiece (70.0) in field 1 (length of the section);

•  press[ENTER];

• enter the value of the third angle (-90.0°) in field ^α (value of the angle in relation to the next section);

•  press [ENTER]. The next section will be drawn in automatic mode. The section to which the data refer will be marked;

• enter the length corresponding to the fourth section of the workpiece (20.0) in field 1 (length of the section);

• enter the value of the fourth angle (90.0°) in field  (value of the angle in relation to the next section);

•  press [ENTER]. The next section will be drawn in automatic mode. The section to which the data refer will be marked;

• enter the length corresponding to the fifth section of the workpiece (30.0) in field 1 (section length);

•  press[ENTER]. The drawing has been completed.

How to carry out a roller levelling operation

When carrying out a roller levelling operation, remember that by convention, there must  be a section of metal plate before and after the roller-levelling step itself.

Supposing that the workpiece shown in the figure must be drawn:

r = 60

 Figure 2.9 - Example of a drawn roller levelling step The cursor will be in polar drawing data entry field 1:

• enter the length corresponding to the first section of the workpiece (20.0) in field 1;

•  press[ENTER];

•  press [ Roller levelling ]. The roller levelling data window will appear;

• enter the desired roller levelling angle (90.0^°) in field^αc;

•  press[ENTER];

• enter the roller levelling radius (60.0) in field R;

•  press[ENTER];

• enter the length of the required roller levelling step in field P;

•  press [ENTER]. The next section will be drawn in automatic mode. The section to which the data refer will be marked;

• enter the length corresponding to the last section to draw (30.0) in field 1 (section

How to carry out a bend-and-press step

 Figure 2.10 - Example of a drawn bend-and-press step

The cursor will be in field 1 of the polar drawing data entry window;

• enter the length of press-and-bend side L1 (30.0) in field 1;

•  press[ENTER];

•  press[ Press-and-bend ];

• enter the intermediate press-and-bend angle (e.g. 45.0°) in the alpha field;

•  press [ENTER]. The next section will be drawn in automatic mode. The section to which the data refer will be marked;

• enter the length of the current section (100.0) in field 1;

•  press [ENTER]. The cursor will move to the ^α field where the angle is entered in relation to the next section;

• enter the angle value (-90.0^°);

•  press[ENTER]. The cursor will move to field 1 where the section length is entered;

• enter the length of the side (100.0) in field l;

•  press[ENTER];
