Die-Design and Simulation
involving multiple deforming bodies, engineers use the soft- ware to study installation and subsequent joint strength.
The Deform interface is tailored for designers and engi- neers, even those with no finite-element-analysis experience. A guided workflow simplifies setup of multiple-operation process chains. Users may incorporate heating, forming, joining, testing or die-stress analysis into a single simulation, and projects reportedly can be reused and modified efficiently and easily, allowing many design iterations to be evaluated in a short period of time. Projects also can serve as the foun- dations for cutting-edge design-of-experiments and opti- mization studies.

Enhancements and
New Features Galore Software: Logopress3 2018 Version
Logopress Corp., along with its North American technical center, Accurate Die Design Software, Inc., has released the 2018 version of SolidWorks-based Logopress3 die-design software, including nearly 30 pages of enhancements and new features.
For example, Logopress3 now can show, underneath the

punches, the slugs that will fall though die openings. While performing a strip layout and defining cutting punches, it is common that the slug being cut does not match the exact shape of the punch, perhaps due to overlap with prior cutting punches. But it is useful to see the exact shape of the slug.
Once the strip layout completes, showing the strip size as well as tonnage required for the die, the designer can select a press for that die. With the new software version, the designer can select from a family of tool templates for a particular press and also customize the templates. This pro- vides standardization among users and is helpful for new
users who simply can select die parameters from a predefined database.
Similarly, as designers create a die they can choose a pre- defined group of components from another database and insert them using the new Logopress3 Insert a Set of Com- ponents command. Not only does this insert a group of components along with all applicable fasteners and springs, it also cuts all pockets and holes automatically with a single validation mouse click.
Also, Logopress3 die simulation and dynamic-interference detection has been expanded to include static interference. And, two types of motion have been added–traction and connecting rod/crank. These new motions benefit companies that create stampings using fourslide and vertical slide- forming machines, as well as those running transfer dies. For ordering purposes, in the bill of materials, users now automatically can add an oversized machining allowance to the finished dimensions of the stock size.

New Functionalities for CAD and CAM Software: VISI 2018 R1
The latest release of VISI, VISI 2018 R1 from Vero Software, released in North America by TST Tooling Software Tech- nology, LLC and geared specifically for the die market, pro- vides a variety of new and enhanced functionality items for CAD and CAM.
VISI 2018 R1 introduces new sheetmetal developments in progressive-strip development and blank prediction, including the ability to manage constraints of specific faces

Enhanced blanking functionality allows for managing constraint on a sheetmetal part by selecting a specific face, which also could have edges linked to other faces. Also, it is possible to define the face constraint in X or Y, or both, directions, useful should a designer wish to blank only specific faces of a model in step-by-step progressive-die design.
