In the insightful article “Measuring and managing variables for sheet metal forming success” on The Fabricator, the key to successful and efficient sheet metal component formation lies in managing a multitude of variables. These variables encompass the properties and conditions of materials, equipment, and processes. Effective management can result in high-quality components, minimized resource expenses, and optimized employee contributions. However, the failure of a single misbehaving variable can jeopardize quality.
To ensure the harmonious collaboration of variables in your operations, it’s crucial to measure each one and understand its acceptable operating range. Statistical process control provides a framework to measure variable operating values against upper and lower control limits. Manufacturers of equipment and materials provide information about the usable operating range of their products, and experienced professionals and laboratory research can further enhance your understanding of how materials respond to operational demands and component geometries.
Some variables can be measured directly and accurately in real time, including strokes per minute and ram speed. Tonnage monitoring, for instance, helps identify various issues, from unbalanced loading to tool wear. On the other hand, properties like a material’s tensile properties are typically estimated and assumed, with variations introduced by rolling mill operations.
