Jonathan Abir, Paul Morantz, Stefano Longo and Paul Shore. An accelerometer based-feedback technique for improving dynamic performance of a machine tool. 16th International Conference of the European Society for Precision Engineering and Nanotechnology, 30th May - 3rd June 2016, Nottingham, UK.
Abstract
A novel concept for improving machine dynamic performance was developed and realised, a virtual metrology frame, for a small size CNC machine with flexible frame. Its implementation in a simplified linear motion system shows a reduction in the magnitude of the first resonance in the plant frequency response function by 12 dB. Realising the concept required developing a real -time accelerometer-based measurement technique. It shows a low sensor noise σ=30 nm with optimal phase delay of <70 μs.
