Abstract

The invention relates to a precise stamping layout method, which establishes a landing edge distance calculation model through parameterized correlation of the thickness and tensile strength of a material, realizes precise layout parameter matching of a metal plate, and improves the material utilization rate and layout efficiency. By establishing a layout algorithm based on geometric symmetry, the manual intervention requirement is remarkably reduced, and meanwhile the dual requirements for the service life of the mold and material saving are considered. Besides, based on a symmetric graphics library construction method, 360 kinds of centrosymmetric layout combinations are generated through an indexing interval discretization processing method, geometric coordination guarantee is provided for multi-cavity parts, and calculation complexity is greatly reduced.
