Benefits of GM Moldflow Standards

Predict - Identify - Solve (Conformal Cooling)

Conformal cooling led to warpage reduction.


Consequences of Ignoring Standards



Incomplete Material Testing

Preliminary Reports - Example


GMW 16365 - The T1 Tryout

Correlation process at T1 tryout
-
Goal – produce an acceptable part for GM10067 submission
-
GM buys good parts, not processes
-
-
Phase 4 – optimum Moldflow process
-
If parts not acceptable, part supplier optimizes process at T1 and forwards process to Moldflow source
-
-
Phase 4a - updates analysis with T1 process and part mold design changes
-
Phase 5 process is run
-
Correlation of final tryout process with Moldflow
-
Correlation Scorecard
-
Documents the T1 tryout
-
Dimensional & appearances responses
-
3 sets of measurements – forward and backward correlation
-
To be filled out during/after the T1 tryout
Some Advice
-
Rely on Experts
- CAE Services has attended dozens of T1 tryouts
- Become Expert-certified, or use our services
-
Be prepared
-
Have a pre-T1 meeting
-
-
Work collaboratively
- Lean on GM
- Working independently can sink a program
- Particularly important at the T1 tryout
-
Be honest when things aren’t working
- Sir Walter Scott – “Oh, what a tangled web we weave…”
- Bad news is way better early than late
- Have opportunity/time to fix problems
- Feedback to Autodesk makes things better for everyone
