Software is keeping vibrations under control

Vibrations during milling lead to rough surfaces and accelerated wear of production systems. A new clamping system combined with simulation software should optimize the process.

Under the name FixTronic , the Fraunhofer Institute for Production Technology (IPT) has developed a system with several partners that responds dynamically to changes during milling to prevent vibrations. A networked clamping system with active vibration damping monitors the workpiece in real time in the ongoing process. Vibrations that come about can be reduced by up to 70% by means of targeted counter-vibrations.

The researchers at the IPT are relying on complementary software for even better results. This helps to identify and avoid critical spindle speeds at which the workpiece itself is made to vibrate, even before processing begins. The simulation also takes account of changes in the object being made during milling. As a result, the scientists were able to reduce surface roughness in the components produced by more than half. The project partners involved include WBA Aachener Werkzeugbau Akademie GmbH, which focuses on digitization in tool construction .
