  • Position sensor for active magnetic bearing with commercial linear optical encoders 
    Tantau, Mathias; Morantz, Paul; Shore, Paul (Elsevier, 2021-05-19)
    Active magnetic bearings are used in a number of applications but their disadvantage is the high asynchronous error due to sensor noise amplification. In this paper a new radial position sensor for active magnetic bearings ...
  • Precision grinding for rapid fabrication of segments for extremely large telescopes using the Cranfield BoX 
    Tonnellier, Xavier; Morantz, Paul; Shore, Paul; Comley, Paul (International Society for Optical Engineering; 1999, 2012-07-11)
    An ultra precision large optics grinding machine, BoX®, was developed and produced at Cranfield University. BoX® offers a rapid and economic solution for grinding large off-axis aspherical and free-form optical components. ...
  • Production of electronics and photovoltaics using a reel-to-reel process 
    Graham, A.; Morantz, Paul; Comley, Paul (European Society for Precision Engineering and Nanotechnology, 2016-06-30)
    Reel to reel manufacturing is a mature technology that involves the passing of a flexible substrate or web continuously through one or more processes. The web is typically much longer than it is wide, and the width in turn ...
  • Sub-surface damage issues for effective fabrication of large optics 
    Tonnellier, Xavier; Shore, Paul; Morantz, Paul; Baldwin, A.; Walker, D.; Yu, G.; Evans, R. (2008-07-14)
    A new ultra precision large optics grinding machine, BoX®has been developed at Cranfield University. BoX®islocated at the UK's Ultra Precision Surfaces laboratory at the OpTIC Technium. This machine offers a rapidand ...
  • Subsurface damage in precision ground ULE® and Zerodur® surfaces 
    Tonnellier, Xavier; Morantz, Paul; Shore, Paul; Baldwin, A.; Evans, R.; Walker, D. D. (Optical Society of America (OSA), 2007-09-17)
    The total process cycle time for large ULE®and Zerodur®optics can be improved using a precise and rapid grinding process, with low levels of surface waviness and subsurface damage. In this paper, the amounts of defects ...
  • Surface quality of a 1m Zerodur part using an effective grinding mode 
    Tonnellier, Xavier; Shore, Paul; Morantz, Paul; Orton, D. (2012-07-11)
    A new ultra precision large optics grinding machine, BoX(R), has been developed at Cranfield University. This machine is located at the UK's Ultra Precision Surfaces laboratory at the OpTIC Technium, North Wales. This ...
  • Virtual metrology frame technique for improving dynamic performance of a small size machine tool 
    Abir, Jonathan; Longo, Stefano; Morantz, Paul; Shore, Paul (Elsevier, 2016-11-16)
    This paper presents a novel concept, a virtual metrology frame, for enhancing the dynamic performance of a machine tool with a flexible structural frame. The dynamic properties of a machine are directly affected by the ...
