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...
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...
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...
Simultaneous Engineering of Sheet Metal Parts
There is a long history of people promoting the idea of simultaneous engineering of product and processes. However, in many cases, the term “simultaneous...
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. ...
High, low, multi-pressure sequence hydroforming? Which process fits?
When a closed section part is designed for manufacture, part shape, material grade, and wall thickness are often driven by the proposed hydroforming technology....
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...
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...
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...
Optimal Stamping Process Plans
To face the metal forming challenges of the future we need to employ methods to engineer processes wherein we evaluate decisions across a broader...
Which way to optimum?
Whenever planning sheet metal stamping products and processes, the goal is always to design the “optimum” process. However, the search for the optimum is...
