How to go beyond educated guessing…
“If at first you don’t succeed, try, try again.”
Systematic process improvement, as described in several previous posts (Adjusting complex process variables: Drawbead shapes, Virtual...
Material Matters: Sheet metal plasticity visualized (part 2 of 2)
As already discussed in Sheet metal plasticity visualized (part one) there are four main components needed to model the plastic deformation of sheet metals:...
Stamping System: Blank Shape, Size, and Location
The blank is one of the first parameters defined in a stamping simulation; it’s mechanical properties, shape, and location in the tool. However, many...
Lubrication values for simulation
We are pleased that the SME (Society of Manufacturing Engineers) Stamping and Dies Technical Group and Metal Forming Simulation Technical Group will host a...
Material Matters: Sheet metal plasticity visualized (part 1 of 2)
As already discussed in the post “Constitutive modeling of sheet metal” there are four main components needed to model the plastic deformation of sheet...
Material Matters: modeling of sheet metal- the “known unknowns”
Modeling of sheet metal stamping can raise many questions regarding the validity of engineering decisions based on finite element analysis. Knowing only the grade...
Robust springback compensation success at Shanghai Volkswagen
Springback compensation is one of the key challenges in the field of die face engineering. We have mentioned the challenges with compensating springback several...
The Stamping System
A recurring theme on this blog, so far, has been sources of variation in production that might not be apparent to engineers when defining,...
In the rearview mirror
Earlier this year AutoForm started this blog, “We Think In Sheet Metal”. Our goal: to communicate directly with you—the metal forming and engineering community. ...
Have you been burned by minimum blank quotes?
Has this happened to you? The sales department wins a job for process engineering, die design, tool build, and stamping production. Upon review of...
Parameters for Hot Forming and Quenching: Engineering and Design
Have you ever defined a hot forming process virtually?
How do you determine which design and process parameters are required for the production...
Why is springback worse for HSS and AHSS?
It seems that you cannot have a discussion about High Strength Steel (HSS) and Advanced High Strength Steel (AHSS) without springback shortly becoming the...
Material Matters: as-shipped vs. as-engineered material
Are all coils created equal? Various coils have potentially different mechanical properties. Source image attribution: www.terexmphs.com
In tryout and production the engineering “boundary conditions” used...
