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.http://www.ultraprecision.org/wp-content/uploads/2016/07/Abir-Morantz-Shore-euspen-2016.pdfhttps://dspace.lib.cranfield.ac.uk/handle/1826/10630A 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.enAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/Accelerometermechatroniccompact machineflexible frameflexible framevirtual metrology framegenetic algorithmConference paper
