AutoForm Forming R12 – Feasibility Evaluation and Verification of the Press Forming Process

Introduction to the application and optimization of springback suppression shapes on wall surfaces.

This article introduces a case study that systematically addresses springback reduction by combining AutoForm-Sigma with shape modification functions, focusing on ultra-high-strength structural members with a hat cross-section. In the first half of this article, we discuss the background and methods of the initiative, as well as the processing steps, including the initial case study on imparting and optimizing springback suppression shapes on wall surfaces. *For more detailed information, please refer to the related links.

Introduction to changing the bending angle in the intermediate processing stage and adding a stepped shape to the upper surface of the product.

This article introduces a case study that systematically addresses springback reduction by combining AF-Sigma with shape modification functions, focusing on ultra-high tensile structural members with hat cross-sections. In the latter part of this article, we discuss changes in bending angles during intermediate processing and the addition of step shapes to the upper surface of the product. Finally, we will briefly verify the feasibility of the anticipated reduction in springback amounts. *For more detailed information, please refer to the related links.

We will introduce the evaluation results considering advanced friction models using TriboForm.

In the simulation study conducted at high tension, where issues are often observed, we will introduce a case that focused particularly on "friction" and worked on improving accuracy. With the goal of enhancing accuracy in the process (drawing die) and reducing lead time, we conducted calculations using AutoForm with two different friction conditions and compared the results with actual panel dimensions. In simulations using constant friction, phenomena that were excessively represented were confirmed to show behavior changes closer to actual panels by using the TriboForm model. This led to a reduction in lead time due to fewer modifications needed in die manufacturing. 【Key Points in Evaluation】 ■ Setting thresholds based on an understanding of the impact of friction (tribology) on quality ■ Establishing a feasible schedule aligned with the trial dates for evaluation ■ FV settings for AutoForm simulation (FV settings: parameter settings suitable for accuracy evaluation) ■ In-depth technical discussions on friction issues and sharing of concerns *For detailed information on the case, please refer to the related links.

Demonstrated excellent accuracy, speed, and consistency in a benchmark study predicting springback at the NIMISHEET2022 international conference.

The international conference "NUMISHEET 2022" on sheet metal forming simulation was held in Toronto, Ontario, Canada from July 10 to July 14, 2022. AutoForm participated in a benchmark study to predict springback using a panel with a twist die provided by the Auto/Steel Partnership (A/SP). This further demonstrated that the software can rapidly, accurately, and consistently simulate the entire press forming process. *For more details, please refer to the PDF document or feel free to contact us.*

Optimize press forming simulation to quickly correct product and die face development through springback analysis in the early stages.

By correcting the springback prediction adjustment, which is usually performed in the final stage of press forming simulation, at an earlier stage, it becomes possible to carry out the process more easily and cost-effectively after mold processing. 【Contents】 - Simulation applying more accurate material information - Mesh and control parameters effective for measuring springback - Simulation of parts that replicate the production plan - Construction of a safe "green" simulation - Notes on setting up springback analysis and measurement *For more details, please refer to the PDF document or feel free to contact us.

Volvo Car Corporation has adopted TriboForm for the door inner of the new Volvo XC90 to achieve its goals.

**Impact of Introducing TriboForm** By improving the prediction accuracy of strain, flow, and springback, we achieve "shortened development time," "reduced development costs," and "increased ROI (return on investment)."

Regarding the "quotation" used at the forefront of sales activities: "Do we really need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving every process is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating the latest interpretations from the National Tax Agency's Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." - Items sent externally are "generally required to be preserved." - Items not sent externally have "no preservation obligation." 2. The sender's judgment: "Is it linked to a transaction?" 3. The recipient's judgment: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to achieve reliable "version management." ■ Summary

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
