Blank Size Engineering (BSE)

The BSE module is used for unfolding 3-dimensional sheet metal parts and estimating blank size, along with blank nesting for maximum material usage, scrap & piece price. BSE can be used to predict thinning, thickening and also to generate a forming limit diagram (FLD).

Key BSE features include:
  • Step-by-step Process Wizard
  • Simple and Advanced unfolding mode
  • Automatic Tipping
  • Inner Fill
  • Double Attached Parts
  • Tailor Welded Blank (TWB)
  • MSTEP (Modified One-Step) Solver
  • Trimline estimation
  • Blank nesting
  • Batch BSE
  • Batch Nesting
  • Blank Development
  • Nesting and cost estimation report in HTML and Excel format
  • Quick feasibility study

Die Evaluation (D-Eval)

Dynaform’s D-Eval module is tailored to analyze CAD based tooling designs during early stage product development cycle. It is equipped with the stamping purpose increment solver which generates reliable formability results in a reasonable response time.

Key D-Eval features:
  • Tipping Adjustments
  • Binder Generation and Modification
  • Surface Morphing
  • Die Design Modification
  • CAM Trim Evaluation
  • Trim Line Check

Die System Analysis (DSA)

The DSA module efficiently predicts most stamping concerns within the stamping production line. DSA consists of three unique capabilities: Die Structure Integrity (DSI), Scrap Shedding/Removal (SSR), and Sheet Metal Transferring/Handling (SMTH).
DSI simulates operational loads to analyze the design integrity of the die. DSI can generate FEA models of the die structure, define operational/stamping loads and evaluate the die structure strength and durability by using implicit and explicit solutions.
The number one cause of stamping line shutdown is the failure of scrap to exit the workstation. This problem can be predicted and corrected in the trim die design stage to avoid troubleshooting in the stamping plant. SHR streamlines model generation for scrap, trim dies, chutes and trim steel. Trimming operations and shedding simulations can be easily setup in the scrap shedding graphic interface.
SMTH simulates the transfer of metal as it progresses through the manufacturing process. It simulates the transfer of the work-piece to the initial die station, movement between stations, pick-up of the finished part and placement on the shipping rack. Part deformation generated in the simulation is used to predict interference between the work-piece and tools. The stress/strain results can be used to prevent damage during transportation, as well as loading and unloading operations.

Dynaform NX Modules

BSE-in-NX

The BSE-in-NX is a complete solution for accurately estimating blank size along with blank nesting for maximum material utilization, minimum scrap and piece costs—all within the familiar NX environment. The solution can quickly produce a blank outline for blank size estimation along with piece price and scrap calculation.

D-Eval-in-NX

The D-Eval-in-NX facilitates engineers to analyze die design within the NX environment using an efficient non-linear finite element program specially developed for simulation of sheet metal forming processes.
