CALIBRATION
The CAL (calibration) field on the L-ALPHA PRODUCT STATUS page is
used for the automatic compensation of varia
tions in sheet metal thickness.

Calibration (procedure)
To ensure the good working of this function, it is necessary that the
"set down" on the sheet metal with minimum pressure without bending it.
The principle of fun
The bea pproaches the sheet at minimum speed and pressure, the
f the sheet will stop the beam. This stop allows to measure the
the sheet under the punch, and in the case of a difference with
eet, to make a correction.
It is thus essential that the sheet is rigid enough to stop the beam with
flexing, otherwise the measure will be false.
Calibration is only possible on sequence N° 1.
Measure a reference sheet with a micrometer.
Introduce this value in the Th field.
Program the CAL field at
3.
Verify that the DNC is on the sequence N1.
Change to
mode.
Place the reference sheet in the tools and bend.
Once the bend is finished, the CAL field changes automatically to the
value 4, which confirms that the calibration has been ade.
he calibration is only done once for a series of products of the same
ickness.

After calibration, it is possible to work in mode. The measurement of
the sheet is made for each product on sequence N1.
To leave this work mode, clear the CAL field using the
key.
If any modifications are made to the tools, it will be necessary to repeat the
calibration.
