University of Saarland Chair of Process Automation: Adaptronics for machine tools
The research focus on "Adaptronics for machine tools" is part of this picture. This program, which in May 2003 received six-year funding from the Deutsche Forschungsgemeinschaft (DFG – German research foundation), aims to use adaptronics to raise the performance of machine tools. As part of this nationwide research focus, the Chair of Process Automation is working on the project "Adaptronics components to remove and isolate vibrations in machine tools". Research, will amongst other things, investigate the practical applications of a dynamic vibration damper, developed by the LPA and since patented, based on highly magnetostrictive materials.
The first stage is to identify the dynamic behavior of the test subject, in this case a lathe. An OROS brand OR38 multi-analyzer was used to measure Frequency Response Functions (FRFs) in the workpiece-tool holder area during impact tests. The second stage was to test the effect of the tool-mounted dynamic vibration damper, by using the multi-analyzer to measure the tool's acceleration signal at normal speeds.
