  • Abir, Jonathan; Morantz, Paul; Longo, Stefano; Shore, Paul (European Society for Precision Engineering and Nanotechnology, 2016-06-30)
    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 ...
  • Tantau, Mathias (Cranfield University, 2015-12)
    Roll-to-roll printing on continuous plastic films could enable the production of flexible electronics at high speed and low cost, but the granularity of feature sizes is limited by the system accuracy. Technologies such ...
  • Zhao, Gang (Cranfield University, 2014-09)
    The aims of this MSc research project are to investigate the application of aluminium for the main components of an ultra-precision spindle defined for use in R2R production systems and to produce a reel to reel rotary ...
  • Castelli, Marco (Cranfield University, 2012-10)
    In this thesis, the research and development of a novel rapid figuring procedure for large ultra-precise optics by Reactive Atom Plasma technology is reported. The hypothesis proved in this research is that a metre scale ...

  • Chavoshi, S. Z.; Goel, Saurav; Morantz, Paul (Elsevier, 2017-04-18)
    A sequential micro-machining process chain is described as the machining strategy whereby two or more micro-machining techniques are implemented in sequence on same or different machine tools. This is in contrast to hybrid ...
  • Lim, Chee Wang (Cranfield University, 2009-12)
    A dynamically optimal design is essential for a motion system to perform high speed operation without compromising its accuracy, settling time and vibration specification. Good design practice which accounts for dynamic ...
  • Castelli, Marco; Jourdain, Renaud; Morantz, Paul; Shore, Paul (2012-09-13)
    The next generation of ground-based astronomical observatories will require fabrication and maintenance of extremely large segmented mirrors tens of meters in diameter. At present, the large production of segments required ...
  • Comley, Paul; Morantz, Paul; Shore, Paul; Tonnellier, Xavier (Technische Rundschau, Hallwag Publishers; 1999, 2011-04-21)
    The next generation of ground based telescopes require many hundreds of metre scale off-axis mirrors. In this paper the grinding of a 1.45m scale Zerodur® mirror segment for the European Extremely Large Telescope (E-ELT) ...
  • Norman, James; Tonnellier, Xavier; Morantz, Paul (European Society for Precision Engineering and Nanotechnology, 2016-06-30)
    The current strategy for measuring non-specular metre-scale surfaces – for instance segmented freeform optics post-grinding – in the mid- frequency bandwidths (S-filter), involves the use of contact probe based systems ...
  • Bennett, Adam; Jourdain, Renaud; Kirby, Paul; MacKay, P.; Shore, Paul; Nicholls, John; Morantz, Paul (European Society for Precision Engineering and Nanotechnology, 2016-06-30)
    Activated plasma figuring using microwaves aims at providing highly efficient activated energy beams for rapid fabrication of optics. The chemical nature of this type of energy beam leads to targeting silicon-based ...
