Physical tools for trimming operations in forming of a sheet-metal part are set up based on numerically-simulated structural behaviors. FEA model representing a stamped sheet metal before trimming and a trimming operation setup are received. Each trim-steel contains a set of cutting-edge nodes associated with trim vector. At least one trim line is established by projecting cutting-edge nodes onto the FEA model according to the trim vector. Numerically-constrained node-pairs along the trim line are created at intersections with edges of crossed finite elements. FEA model is modified by splitting the crossed finite elements to preserve original geometry and to ensure numerical stability. New finite elements are defined using one of the nodes in corresponding node-pairs such that no finite element straddles the trim line. At each solution cycle of a time-marching simulation of trimming operations, simulated structural behaviors are obtained as the scrap portion(s) deforms and falls accordingly.

A camera photographs a part to be estimated, which is produced by cutting a sheet metal in advance, and a dimension reference marker. An image processing unit generates edge data by extracting an edge of the part photographed by the camera, and enlarges or reduces the edge data based on a size of the dimension reference marker photographed by the camera such that a size of the edge corresponds to an actual size of the part. A machining time calculation unit calculates a length of a cutting line for cutting out the part from the sheet metal based on the edge of the edge data corresponding to the actual size of the part, and calculates a machining time for producing the part by cutting the cutting line in accordance with a material and a thickness of the sheet metal.

An improved production plan is created for producing a three-dimensional component from a metal sheet by cutting, bending, and/or welding.
