General

Engineering Research Center for Net Shape Manufacturing (ERC/NSM)

The ERC/NSM is the leading university associated group in North America conducting R&D and providing education in metal forming (stamping, sheet & tube hydroforming, forging) since 1986. In addition to training students, we conduct R&D projects for government agencies, e.g. National Science Foundation and for a Consortium of companies worldwide as well as individual companies, on a confidential basis

Please review our R&D activities in (click on the titles below for a detailed description of the topics)

  • Stamping including Sheet Hydroforming (material characterization / die design and optimization / friction, lubrication and wear / process simulation / equipment characteristics and selection / bending and springback)
  • Proprietary Stamping R&D is also conducted for a group of companies at the Center for Precision Forming (CPF). To review the titles of ongoing studies please click on        www.cpforming.org
  • Precision Cold, Warm and Hot Forging (material properties / process design and simulation / die materials and coatings / friction and lubrication)
  • Tube Hydroforming (determination of tube properties / process simulation and optimization / lubricant evaluation)
  • Education (Training courses in forging, stamping and tube hydroforming

On going ERC/NSM projects (updated on Sep. 5. 2012)

(1) Bulk metal forming (forging) related projects
 

  • Design a cold/warm precision forming process to manufacture stainless steel parts for medical application, with minimum amount of machining.
     
  • Predict distortion of large rolled and hardened rings. Develop a compression/expansion method to reduce residual stresses and distortion in rolled and heat treated rings.
     
  • Develop a method for hot precision forging spur and helical gears from composite materials to save weight.
     
  • Design hot precision forging methods for producing bevel gears with minimum machining and materiel usage.
     
  • Investigation of fracture and crack formation during hot forging of stainless steel and Ni alloys. Estimate the forging conditions (temperature, strain, strain-rate) that reduce the probability of fracture.
     
  • Prediction of stress in precision hot and cold forging dies and design of tooling to prevent low cycle fatigue fracture.
     

(2) Sheet metal forming projects
 

  • 3D FEM simulation of blanking of non-round parts; investigation of different fracture criteria for separation during blanking.
     
  • Determination of flow stress of sheet materials under biaxial deformation conditions, using hydraulic bulge and dome tests.
     
  • Evaluation of lubricants for stamping in production of automotive parts.
     
  • Evaluation of die materials/coatings/heat treatments for stamping AHSS.
     
  • Process simulation for hot stamping to optimize process conditions and die design with cooling channels.
     
  • Forming of Aluminum/AHSS sheets by using servo press.
     
  • Forming of Titanium alloys at elevated temperatures.
