Fully automatic volumetric compensation
of coordinate measurement machines and
machine tools
Etalon AG will launch its new interferometer
based measurement system LineCal® during
the Control show. The LineCal® system is
addressed to manufacturers of compact multi-
sensor measurement systems, coordinate
measurement machines and machine tools who
want to calibrate their machines fast and very
precisely prior to the delivery to their customer.
At the same time, the Etalon system reaches
extraordinary high precision in the error
determination: even deviation parameters which
are very difficult to measure, i.e. the roll of the axis,
can be determined extremely precisely with this
patented principle of measurement.
Several firmly fixed measurement channels are
replacing the motoric tracking
In one setup LineCal® records all systematic
geometry deviations (deviation in position,
straightness, pitch, yaw, and roll of all three axes
and squareness) based on the laser wavelength
and generates the volumetric compensation data
directly in the specific format of the machine
controller. Intelligent routines make the setup
easy; the measurement routine for the complete
volumetric compensation is being carried out
automatically in 40 to 60 minutes. The effort for the
calibration is reduced considerably.

LineCal® is based on the approved interferometric
principle of measurement of which Etalon is
already making use of in its other measurement
systems. In order to save space and weight,
Etalon abandoned the tracking of the measuring
beams. A simple but specially tailored fixture with
a large number of pre-installed interferometric
measurement lines is being used instead for each
machine type.
