Automated measurement of railway fishplates

The company Mills CNC is a supplier of machine tools. They use MicroEpsilon laser sensors for the automatic inspection of large, hot-rolled railway fishplates made of steel. These fishplates join two rails together and must be as straight and flat as possible. In a machine tool automation cell specially developed by Mills CNC for this task, both the bend and a twist of the fishplates are determined. For this measurement task, an optoNCDT 1750 Micro-Epsilon sensor with a large measuring range of 750 mm is mounted on a robot. Its compact sensor design and direct data output without external controllers enable easy integration.
