Quieter machining - active jerk decoupling reduces machine vibrations

This research article shows what active jerk decoupling can do for the machining dynamics and precision of a machine tool.

Faster and more precise at the same time!
Machine vibrations often lead to a conflict between fast positioning and high accuracy of the feed axes. The Institute of Production Engineering and Machine Tools (IFW) at Leibniz Universit├Ąt Hannover is researching the method of so-called "active jerk decoupling" based on the above-mentioned facts. This allows the limits of maximum axis dynamics and achievable accuracy to be significantly extended. In the DFG-funded project "Active jerk decoupling for machine tools", machine vibrations are actively compensated by a mechatronic damping system.

How does active jerk decoupling work?

At the heart of the system with isoloc's FEDAM spring assemblies is a cascading filter that effectively decouples the reaction forces of the feed drive during acceleration and deceleration. Think of it as a high-precision shock absorber system that compensates for unwanted movements while increasing control and accuracy.

Advantages of the system

  • Increased precision: By reducing vibrations, greater accuracy in machining is achieved.
  • Faster machining: The improved dynamics allow faster movements of the machine parts without loss of accuracy.
  • Longer machine service life: Less vibration means less wear and tear and a longer service life for machine components.
