ANEXO 1. SOFTWARE ESA S630 A48
Example: if a step correction is made equal to -2.0° and a piece correction equal to -1.0°, the angular
correction of that step will be -3.0°.
At the end of the operation for setting of the correction data:
- Press
- Press the button to reposition the back gauges axes (a correction may have been made to their
position).
- Repeat the bend.
- Check that the bend is correct:
- If correct: Repeat the procedure for all the bends of the program; to move between the various bends
press the or buttons.
- If incorrect: Make new variations to the data corrections of the current bend.
Once the data have been corrected for all the bends:
- Press ; the automatic cycle will start from the bend currently selected.
- There are new methods for setting the corrections which are described below.
Corrections internal radius
It is possible to display the internal radius of the bend on the Editor page. The internal radius is always
calculated, either in graphic or numeric, the calculation method can be selected from the generic
parameters. The change of the internal radius will influence the stretch calculations, but only if the program
is numeric. If the program has been generated in graphic, the change to the internal radius will not
recalculate the stretching.
Consult the machine parameters manual for the various application modes for the internal radius.
3.12 Selection of the DIN formula to calculate the stretch
It is possible to select the standard DIN formula if you need to use it (for calculating the stretch). In order to
select the standard formula, set the generic Stretching Formula parameter to 1. This Field can also be
changed by the operator from the
4>> User Parameters page.
Checking the program
Once the changes have been made, press START to take the axes into position. The check of the
program will be realized automatically and in case any errors are detected, a message will then be sent
which will remain in semiautomatic STOP status.
Self-Teach cycle
There are special situations in which it is not possible to use the bend quota calculated by the numeric
control for carrying out a bend (rounded punches, coining bends, bends outside the V-die, etc...).
In these circumstances it is helpful to use the self-learning cycle of the bend quota (L.D.C. point) you want
to insert on the SEMIAUTOMATIC page.
If this procedure is activated, any step change will be made at the end of a bend, the cycle will remain on
the current bend to allow the operator to execute the self-learning of the desired height of the end of the
bend (L.D.C. point).
