Influencing factor Description
Unrelaxed angle
When measuring at the machine, make sure that the bend-
ing tool has been lifted sufficiently and the legs of the angle
are relaxed. The setting of the press brake for decompres-
sion must be adjusted as necessary.
Deformations
due to gravity
In case of thin sheets with legs of equal length, elastic de-
formation can be caused by its own weight, depending on
the position of the sheet, therefore changing the angle
compared to an unloaded state.
External magnetic fields
Make sure there are no generators of magnetic fields (e.g.
electric drives) within a distance of 10 cm.
Strong external light sources
There should be no light sources (e.g. infrared lamps, other
laser devices, strong reflections of the own laser beam and
high-frequency LED lightings) in the surrounding area of
the device.
Condensation
Condensation on the surface, e.g. of the test specimen,
lens or mirror, must be prevented. Slow adjustment to the
ambient temperature is necessary.
5.2.1 Positioning
Since the measurement principle of KeMes A2xx is based on the reflection
of a laser beam, attention must be paid to the correct positioning of the de-
vice. Measurement is not possible on bent workpieces or in the bending ra-
dius.
Information
For an exact measurement, a minimum distance of 20 mm between the de-
vice and the surface of the workpiece is required.
