Intelligent Die-Face Design using Morphing Technology

Background

  • Automotive manufactures are facing challenges to reduce the lead time for product development to meet rapid changing market demands.
  • In vehicle development, conventional Die-Face Engineering (DFE) requires lots of tryouts before a new die can be used in mass production.
  • Similarities of parts commonly exist among product generations or in the same product family, which provides the possibility to make use of the existing tooling/die design for new part production.
  • Morphing allows the possibility for the knowledge and experience learnt from the die-face design of one product (Generation i) to be mapped/morphed onto that for a new but similar product (Generation i+1).

Approach

  • Part-to-part mapping function by geometry registration method
  • Die-to-die morphing and springback compensation
  • Formability prediction by the strain increment method
  • Die addendum morphing by extrapolation of the morphing area of the part surface
  • Morphing related boundary continuities and trim line detection

Objective

  • Develop methodologies to expedite DFE process by integrating the information of new part (Gen i+1), existing part and die (Gen i) for new die design (Gen i+1)
