Sheet forming software offers automatic springback compensation

Engineering Technology Associates Inc. (ETA) has released Dynaform Version 5.9.3. The software simulates the sheet forming process and analyzes the entire die system.

This version offers improvements in blank/trim line development, including combining the interface for blank development and trim line development. With this version, it is possible to develop the blank outline and trim line simultaneously. In addition, the user can develop partial blank outlines and partial trim lines and develop a blank outline with a cut pattern.

The new Auto SCP feature is used for automatic springback compensation iterations. When running the springback function, the user first defines the stamping stages. This is achieved using the step-by-step guided user interface. The user then defines the tool to be compensated, compensation zone, compensation method, scale factor, and iterations for a customized result.

The program automatically checks the springback amount and calls the solver to make a compensation adjustment for the tooling mesh. The compensated tool then replaces the original tool, and multistage jobs are rerun until the solution is found.

The software also offers process templates that allow the user to define forming processes for typical cases. It automatically creates the stages within the template for analysis. For example, a user can use a process template for a fender/hood inner or outer, a roof door inner or outer, and a lift gate inner or outer. The user also can import and export to and from the saved template library.

New license control with license roaming allows the user to borrow a license from the server to use the software outside the network temporarily. The new license control also supports a redundant license server within the network, which minimizes license server downtime.
