A tool used in metal fabrication estimates the force required to bend a piece of sheet metal to a specific angle and shape. This estimation considers material properties like tensile strength and thickness, as well as the bend’s length and die opening. For instance, forming a sharp bend in thick, high-strength steel requires significantly more force than bending thin aluminum into a gentle curve. The output, typically expressed in tons, helps fabricators select the appropriately sized press brake for a given job.
Accurate force prediction is crucial for preventing damage to the workpiece, the press brake itself, and ensuring the final product meets specifications. Underestimating the necessary force can lead to incomplete bends or workpiece fracturing. Overestimating can damage the press brake or create excessive springback in the material. Historically, such estimations relied on experience and manual calculations, introducing potential inaccuracies. This automated approach offers enhanced precision, streamlined workflow, and improved safety.
