We have published a CAE case study titled "Optimizing the Conditions for Burring Processing | CAE-Based Design of Experiments (DOE) Analysis Case."
In press die design, the settings for "pilot hole diameter" and "vertical wall height" in burring processes tend to rely on empirical rules and trial-and-error. This is particularly true for high-strength steel sheets (high-tensile), where the risks of cracking and thickness reduction are significant, requiring a considerable amount of time to establish conditions.
The plastic processing simulation software "DEFORM" addresses these challenges.
【Identify the "correct answer" with CAE before actual prototyping】
By utilizing DEFORM's "Design of Experiments (DOE)" feature, multiple conditions such as pilot hole diameter and punch shape can be digitally verified all at once for formability. This allows for a quantitative understanding of forming limits and cracking risks, enabling the derivation of optimal processing conditions in a short time.
