Effective Dynamometer for Measuring High Dynamic Process Force Signals in Micro Machining Operations
(2012)Procedia CIRP ~ Fifth CIRP Conference on High Performance Cutting 2012The authors present an innovative piezoelectric dynamometer (MicroDyn) providing the base for measuring high frequency signals in micro machining operations. Cutting tools with one or more cutting edges used in micro machining processes are mostly running with rotational speeds of more than 100’000 rpm, resulting in high excitation frequency. Thus, the interference of the excitation frequency of those processes with the natural frequency ...Conference Paper
