Press tool simulation has been widely used
since the early 1990s. The goal is to take the uncertainty
out of the die design process by predicting splitting,
wrinkling, thinning, surface defects and springback
problems before any metal is cast. International
benchmarks such as those hosted every three years by
NUMISHEET
have proven the accuracy of the method (see also our
Publications for further
information). Dutton Simulation aims to bring to our
clients the benefits of using simulation as part of
the die development process by offering the best available
software, supported by a range of related services.
FASTFORM Advanced and CATSTAMP
In
addition to their superb tools for cost optimisation,
product feasibility and process engineering, FTI also
offers FASTFORM Advanced
and CATSTAMP for detailed
tooling simulation. These systems allow rapid evaluation
of tooling proposals with consideration of blankholder
curvature, blankholder pressure, drawbeads, lockbeads,
pressure pads and tooling pins. They also include advanced
features such as support for tailor-welded blanks, user-defined
blank shapes and even springback calculation.
eta/DYNAFORM and Die Evaluation
Engineering
Technology Associates, Inc. (ETA) is a software development
and engineering company specializing in automotive CAE
applications worldwide. Together with LSTC, the developer
of the general purpose finite element solver LS-DYNA,
ETA has developed the DYNAFORM package
tailored for solving sheet metal forming problems.
Using DYNAFORM prior to tool build can save
significant time and cost. The latest version
offers springback compensation methods developed in
collaboration with the Big Three automotive OEMs in
North America.
In addition to the core DYNAFORM system, ETA's developers
have produced a toolkit for Die Evaluation. Since
most tooling designs are done in a CAD environment,
DYNAFORM’s D-Eval Module was specially created
to support and analyze CAD based tooling and engineering
designs. Dutton Simulation also offers a range of tools
for CAD-based tooling geometry generation from our partners
at FTI and OmniCAD - please contact us for further details
The DYNAFORM package is developed from ETA's core range
of general purpose pre-
and post-processing tools for finite element
modelling and analysis (linear and non-linear) which
are also available from Dutton Simulation.
Complimenting these systems, we also supply the CAD
translators from Datakit to allow native
CAD formats such as CATIA, ProE, UG, etc to be converted
to IGES, STEP or DXF for import.
