AI Technical Summary

Technical Problem

Existing technologies cannot automatically determine the causes of defects in the manufacturing process of sheet metal parts, resulting in the inability to effectively reduce or eliminate undesirable defects such as material wrinkling or tearing.

Method used

By using computer-based methods, the simulation results of manufacturing or deformation processes are analyzed to identify dangerous areas in parts and their causal lines and trajectories, and the forming process is automatically adjusted to reduce stress or force, including modifying the geometry of parts and tools.

Benefits of technology

Quickly identify and reduce defective areas in parts, improve the reliability of the manufacturing process, reduce the risk of material wrinkling or tearing, and optimize manufacturing process parameters to improve part quality.

Abstract

A computer-implemented method for analyzing simulation results of a manufacturing or deformation process, comprising: obtaining simulation results, the simulation results comprising at least a geometry of a part (2) and a stress tensor (23) in the part (2) caused by a shaping process; for one or more origins (32) in a critical region (22), determining an origin line (3) by following a direction of maximum stress or a corresponding force; for each origin line (3), determining at least one line segment (31) of the origin line (3) and an origin trajectory (5) representing values of the stress or force directed along the origin line (3); and performing at least one of presenting information representing the line segment (31) and the origin trajectory (5) along the line segment (31) to a user and automatically adjusting parameters of the shaping process.
