the risk of cracking across progressions. Deform also proves popular, say company officials, for modeling of blanking operations, where users optimize shearing behavior while minimizing burrs and other undesirable features. Advanced solid meshing tools allow coined geometries to be resolved with fine feature detail.
The Deform interface is tailored for designers and engi- neers, even those with no finite-element analysis (FEA) experience. A guided workflow simplifies the setup of mul- tiple-operation process chains. Users may incorporate heat- ing, forming, joining, testing and/or die-stress analysis into a single simulation. Projects reportedly can be reused and modified with ease, enabling quick evaluation of many design iterations.
The projects also serve as the foundation for design of experiments and optimization studies. These studies enable users to troubleshoot problems, optimize designs and test process robustness.

The software’s FEA technology provides valuable infor- mation about process output early enough in the develop- ment cycle to ease any changes that must be made, according to company officials. This is accomplished without the need for making tools, consuming machine time, scheduling manpower and buying raw material for shopfloor trials. Scientific Forming Technologies Corp.: www.deform.com
User-Requested Enhancements Added, Plus New Costing Functionality Logopress3
Version 2019 SP0.5 of Logopress3 die design software, from AutoForm Group and distributed in North America by Accurate Die Design Software, Inc., now includes a costing module that helps determine the cost of the tool based on material cost. This new costing functionality is available to users while in the strip layout or tool assembly areas of the software.
A strip assembly easily and quickly can be inserted into a tool template that already contains plates with predefined material types and sizes. These plates, along with the die set, then can be easily modified to whatever size the user wishes by simply double-clicking anywhere
Along with the other motion types included in Logopress3 Die Debugger, a new traction type has been added, easing motion simulation of gears, rollers, and rack and pinions.
on a plate and adjusting the dimensions of that plate. Depending on the design intent of the user, this change then updates either that plate and related plates, or it updates the entire assembly of plates, according to com- pany officials.
At the request of users, the Round Draw module in Logo- press3 now can run with nonflanged cylindrical parts, such as parts to be created in a transfer press or those whose stretch web would be pulled into the draw cavity. Additional inputs have been added to this module, such as the option to enter a friction coefficient and another to enter a user- defined stripper force. Another new option allows the display of the maximum critical load at each draw station in the strip assembly, beyond which carries the risk of rupture.
To keep the software’s Die Debugger portion simple and rapid to set up, Logopress3 added tools to provide two new motions, say company officials. The first new motion allows the motion simulation of a component via traction or fric- tion. Component applications include gear mechanisms, rack-and-pinion assemblies, and rollers. Also added are tools for the rapid setup of a connecting rod and crank motion, enabling Die Debugger’s movement of a slide or other piston-type mechanism.
Logopress3’s nesting software has been improved to sup- port multiple sheets of material. This new multi-sheet mode automatically uses as many sheets as needed to place all the parts selected by the user for nesting. This update has been rolled out to users of the nesting software as well as those who have the die design software.
