ANNEX G: SUNDRIES

PAGE 67

To ensure the good working of this function, it is necessary that the beam can
"set down" on the sheet metal with minimum pressure without bending it.

The principle of functioning is as follows:

The beam approaches the sheet at minimum speed and pressure, the resis-
tance of the sheet will stop the beam. This stop allows to measure the thick-
ness of the sheet under the punch, and in the case of a difference with a ref-
erence sheet, to make a correction.

It is thus essential that the sheet is rigid enough to stop the beam without
flexing, otherwise the measure will be false.

Calibration (procedure)

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 made.

The calibration is only done once for a series of products of the same thick-
ness.

Use

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.
