Die-sink EDM in meso-micro machining
(2012)Procedia CIRP ~ Fifth CIRP Conference on High Performance Cutting 2012Micro EDM has been identified since more than a decade as suitable process for machining complex shaped structures with high aspect ratio, though only through variations of EDM such as micro EDM milling, micro EDM drilling, coated electrodes etc. In the current paper, we present the research focused on analysing the capability for implementation of die-sink EDM in meso - micro scale machining (structures with surface area smaller than ...Conference Paper -
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
