What is the future of engineering hemming processes?
During the past 20 years, stamping simulation has brought tremendous change to the way stamping processes are defined and validated, stamping tools are designed...
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...
What is passing?
After the recent posts on failure prediction based on FLCs, several inquiries arrived through the blog and social media, regarding interpretation of other outputs for...
Adjusting complex process variables: Drawbead shapes
In Finite Element Analysis, it is common to treat the metal restraint due to draw beads as numerical factors applied along a curve or...
Hemming feasibility
We had the honor to be selected as the computer simulation partner for a recent Auto/Steel Partnership (A/SP) study that considered the feasibility of...
Material Matters: Knowing your limit
The Formability of sheet metals
Previous posts Materials Matters, "the known unknowns" and “Material plasticity visualized” covered the general aspects, common terminology, and formulation of...
Stamping System: Press speed and lubrication challenges
Lately, one of the most frequently asked questions in metal forming simulation has been “Can your software model the effects of a servo press?”...
Tribology, friction, and lubrication: A new dimension to metal forming simulations
In our previous post on the stamping system, several environmental variables within production sheet metal stamping are mentioned. In that post we listed variables...
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...
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...
Success Story: Godrej Tooling implements robust compensation
Springback of sheet metal stamped parts is a challenge faced by tooling suppliers and their customers; parts produced in stamping dies require significant effort...
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. ...
Infinitely adjustable presses, when should we stop adjusting?
Numerical controlled (N/C) cushions have previously been the realm of large OEMs and Tier 0.5 stampers in their newer large presses. Until now, the...
Options for Effective Draw Bead Modelling
Do you ever think about the numerous options for draw bead modelling? When and why should we use numerical line beads?
When is it...
Simulation Accuracy: Input Definition and Results Interpretation
Has it ever happened to you? A simulation report shows a design is safe – green with no splitting failures, no red or yellow...
Simultaneous Engineering Case Study – KTH Parts Industries
KTH Parts Industries has a relatively unique position in the automotive stamping industry; they are a tier-1 automotive parts supplier, serving only one customer...
Virtual Tryout or Process Engineering?
In simulation, there is ongoing effort to prove who can claim to be the best at “virtual tryout.” Product brochures and websites promote software...
