DESCRIPTION:If UK manufacturing is to compete with cheaper alternatives\, 
 it needs to\nbe high-tech.  Parts made out of metal can in general be shap
 ed by three\nmethods: additive (a.k.a. 3D printing)\, subtractive (i.e. ma
 chining away\nthe bits you don't want)\, or forming (i.e. forcing the meta
 l into the\nright shape).  3D printing is slow and does not produce high q
 uality\nresults\, whilst machining is wasteful of both energy and money.  
 Forming\nworks well\, and is used for everything from coke cans to jaguar 
 cars\,\nbut a new design means building a new expensive machine to make it
 .\n\nWhat if there were a general purpose forming machine?  It could take 
 a\ncomputer design and a blank piece of metal (e.g. a sheet\, or a block)\
 nand form the metal into the desired shape.  It could take a rejected\nmis
 -formed part from a production line and tweak it into the right\nshape.  I
 t could make accurate shapes out of recycled metal of variable\nquality.  
 To do all this\, it would have to understand how to control the\nprocesses
  of metal forming.\n\nIn this talk\, I will present some preliminary work 
 on mathematical\nmodelling of metal forming processes.  This preliminary w
 ork\ninvestigates sheet metal rolling\, which is both a major industrial\n
 process in itself and about the easiest thing we could think of\nmodelling
 .  I will explain how we have applied mathematical modelling to\nmetal for
 ming\, what we have got out of it\, what we have still got to do\,\nand ho
 w we believe this work will eventually contribute to an\nunderstanding of 
 controlling the processes of metal forming.
