an automatic combination of input variables can be configured for one or more issue types grouped simultane- ously. A quintessential scenario would be when splits and wrinkles are grouped together as issues to be resolved. Here, the software will try to strike a balance between splitting and insufficient stretch on the panel.”
Die Quoting and Part Estimating
Eric Bragg, VP/sales engineer, TST Tooling Software LLC, then takes the stage to highlight software capabilities associated with developing initial die costs and piece-part costs.
“Quoting and estimating play an important role in keeping a die shop running successfully,” Bragg stresses. “Precise estimates are essential to maintaining a competitive and prof- itable edge.”
Bragg will describe the latest software features that help diemakers streamlines quoting, develop more accurate cost estimates and generate professional-
looking customizable quotes. You’ll learn how to quicken your quoting process, produce more accurate esti- mates and better manage your quotes.
“The software also now allows shops to manage progression parameters and material utilization,” Bragg notes. “With each step the software will provide the tonnage needed for each operation. It also can quickly and easily simulate a realistic 3D strip with single or multiple parts; provide step-by-step unfolding information; and perform manual and automatic nesting.”
Lastly, Bragg will demonstrate how to quickly turn quotes into jobs, with automatically generated bills of mate- rials, and with software fully integrated to work with existing CAD software.
Reverse Tonnage,
Slide Tipping and More
This presentation highlights die sim- ulation/animation technology and its application, including collision detec- tion. Ray Proeber, president and owner
of Accurate Die Design Software, Inc., will describe how progressive and transfer dies can be simulated in vari- ous press types such as conventional, servo and link-motion. Fineblanking, fourslide, multislide and Bihler machines also can be simulated. Atten- dees also will come away with a good understanding of slide-tipping predic- tion and reverse-tonnage loads.
“Reverse tonnage and slide tipping can wreak havoc on a punch press,” Proeber notes. “Unfortunately, they are overlooked often, sometimes until the press needs to be rebuilt because of them. Reverse tonnage in particular— also known as snapthrough or negative tonnage—can do significant damage to a press in short order. And, while slide tipping is not as destructive on the entire press overall as reverse tonnage, it can easily be addressed so that presses remain in good condition rather than suffering unnecessary, premature wear.”
When it comes to simulation, or look- ing at die kinematics, Proeber contends
