  • 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 ...
  • Thermal analysis of energy beam using de-laval nozzle in plasma figuring process 
    Yu, Nan (Cranfield University, 2016-10)
    In 2012, plasma figuring was proven to be an alternative solution for the fabrication of large scale ultra-precise optical surfaces. Indeed, plasma figuring was successfully demonstrated on a metre class glass surface. The ...
  • Thermal and deformation analysis of joint interfaces in machine tools 
    Gashi, Bekim (2008-05)
    Machine tools are made up of many different parts connected together. In order to understand and create more accurate thermal and deformation numerical models the heat transfer characteristics of machine tool interfaces ...
  • Thermal effects compensation and associated uncertainty for large magnet assembly precision alignment 
    Doytchinov, Iordan; Shore, Paul; Nicquevert, Bertrand; Tonnellier, Xavier; Heather, A.; Modena, Michele (Elsevier, 2019-06-12)
    Big science and ambitious industrial projects continually push technical requirements forward beyond the grasp of conventional engineering techniques. An example of these are the extremely tight micrometric assembly and ...
  • Thermal Performance of a Multi-Axis Smoothing Cell 
    Georgiou, Charalambos Andrew (Cranfield University, 2011-05)
    Multi Axis Robots have traditionally been used in industry for pick and place, de-burring, and welding operations. Increasing technological advances have broadened their application and today robots are increasingly being ...
  • 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 ...
