Computer Modeling 2

Projects

• Mechanical Performance of Dies - Continuation• Design Support for Tooling Optimization • Computational Tool for Short Run Insert Production

and Improved Yield

Computer Modeling 3

Mechanical Performance of Dies - Continuation

• DOE funded– Current activity funded by cost-share only

• FEA modeling of the relationship between – Die– Part– Machine

• Reviewed in February

Computer Modeling 4

Design Support for Tooling Optimization

• DOE funded– No current activity due to funding

• Will extend some of the qualitative and approximate calculation methods used in CastView. 

• Specifically, work to create– Gravity fill version of the algorithms– Thermal field optimization techniques using the

equilibrium temperature technique we developed. 

Computer Modeling 5

Computational Tool for Short Run Insert Production and Improved Yield

• This is a small DLA project for CastView 

• There is funding for one student

• Two components– Yield evaluation & improvement– Database/procedures for linking die bases

and inserts for rapid tooling

• To be reviewed today

Computer Modeling 6

Future Work

• Guidelines summarizing the die distortion work. • Modeling tutorial for distortion modeling.

– Web-based– Basic complete but needs improved – Addresses the boundary condition and “how to”

issues that are difficult in these problems– Make it more complete and more accessible to the

typical user

• Updating computer modeling course– Must match the industry needs and expectations.
