Etalon MultilineEtalon claims its Absolute Multiline Technology offers a measurement system for monitoring the geometric accuracy of machine tools by means of high-precision length measurements: An absolute distance interferometer measuring with sub-micrometer resolution serves as metrological centrepiece of a factory.

The company says it connects with any number of machines via a fibre optic network that may comprise more than 100 measurement channels. These measurement channels, equipped with miniature optical elements, are oriented along the machines’ axes, space diagonals and face diagonals of the machine working volume.

This integration into a machine tool allows continuous monitoring of the geometry of the machine and can initiate machine compensation in order to ensure the dimensional accuracy of the manufactured parts, claims Etalon.
