Development of a flexible mechatronic clamping system for the self-optimization of a milling process by active vibration damping
Project Duration: 1.7.2016 – 31.12.2018
Industry 4.0 in the milling process: Lower vibration levels achieved via active damping and variable speeds
Vibrations occurring during milling operations reduce process efficiency and result in rougher surfaces as well as in high tool wear and workpiece scrap. A trial and error approach to process design is frequently adopted in a bid to minimize vibration This is both time-consuming and costly. In a two-year research project known as "FixTronic", the Fraunhofer Institute for Production Technology IPT and its partners developed a clamping system and simulation software to systematically minimize vibration occurring during milling operations, thereby ensuring more stable, cost-efficient milling processes.
The aim behind the "FixTronic" project was to develop a system capable of reacting autonomously to dynamic changes in the milling process and to actively reduce vibration and instabilities. To this end, the engineers developed firstly an active clamping system for the workpiece and secondly, simulation software which optimizes spindle speed so as to ensure that no natural workpiece vibration is stimulated.
