3.5 Manual calculation of the bending sequence (Optional in the S630 model)
It is possible access the manual calculation procedure from the drawing page of the piece by following the
steps below:
- Press
[Calculate].
Calculation window
A window will open that shows the simulation of the piece to be bent, including the lower and upper part of
the press-brake, the punch, the die, the stops and the piece before to being bent.
On the right side of the page there are three windows that respectively indicate the upsetting and the
number of rotations of the piece relating to the bending sequence found (refer to the figure in the paragraph
on the Automatic calculation of the bend sequence).
Manual searching for the bend sequence
In the manual search the bending sequence is established by the ’operator by forcing the bends.
The operator has the possibility to move between the various bends by pressing the and buttons.
To force the bends it is necessary to press the
[Bend] key in correspondence of the selected bend; if you
press the key in correspondence of a bend that has already been forced, that bend will be straightened.
The operator has the possibility of rotating the piece pressing the
[Rotate] key;
Press [Optimise] when all the desired bends have been forced.
The numeric control searches for the solution keeping in mind the sequence forced by the operator.
Results of the optimisation
If the piece is not feasible, the control will warn the operator with a “ Forced Solution ” message.
In the event that there is no possible forced solution the operator can try to identify which is the bend that
makes it impossible to bend the piece from the manual search of the bend sequence; any collision of the
piece with the various parts of the machine is notified by a colour change on the side of the piece that
enters into collision.
In order to bend a piece even if it enters into collision (for example in the case in which the collision does
not damage the sheet metal) the operator must force the entire bend sequence.
If the piece is feasible the control advises the operator with a
“ Solution Found ” message; the operator
can select the following functions in this window:
-
[Stop]: the optimisation is stopped in order to make changes.
- [Accept]: the values calculated in the solution found are set in the program.
