Metal Folding Techniques in Metal Origami in Aerospace Engineering

Roll Forming

Roll forming plays a critical role in Metal Origami in Aerospace Engineering, enabling the production of long, direct sheet metal parts. like siding, material, and auto primary components. It works by taking care of looped sheet metal through sets of rollers fitted with notches or pins that dynamically twist the material into the ideal cross-sectional shape. Roll forming is a highly automated, high-speed process that considers large-scale manufacturing of complex cross-sections. Compared to other sheet metal forming techniques like stamping, roll forming requires less specific tooling and has lower tooling costs for large production runs of the same part. However, roll forming is limited by the need to produce parts with consistent cross-sections and lengths.

Stamping

Stamping is another common industrial process for shaping sheet metal, where a sheet is pressed into a specific shape by a die. It produces net-shape parts in batches using formed dies and punches. While it can make more intricate 3D shapes compared to roll forming, stamping requires complex and costly die tooling that is shape-dedicated. The tooling changes needed to create new part designs contribute significantly to costs. Stamping is suitable for high-volume production but less flexible for prototypes and low-volume custom parts compared to laser cutting and carving.

Laser Cutting and Forming

Laser cutting uses a highly focused laser beam to cut sheet metal materials. Laser beam power and movement are computer-controlled, allowing for precision cutting of intricate patterns and shapes with minimal heat effect on the surrounding material. Unlike stamping and rolling, laser cutting is a non-contact process suitable for making complex geometries quickly without the need for tooling changes between designs. However, thinner material thicknesses are limited by laser absorption capabilities. Post-processing may also be required to remove burrs or dross from cut edges.

Automated Bending

Bending Mechanisms

There are a few common mechanisms utilized for automated bending of sheet metal. In air bending, the sheet is clasped along one edge and pulled over a forming edge by grippers on the opposite side, bending the sheet into a span corresponding to the edge calculation. This process can use a single-point contact forming edge or roller forming for a continuous curve.

In stretch bending, a sheet is clasped at both edges and pulled horizontally to plastically deform the material by stretching rather than compressing it, as in air bending. Various presses are also utilized, where sheet material is shaped by coming into contact with a tool or die under applied pressure. Press brakes use a lower die and a moving upper punch to wrinkle sheet metal.

Automated Bending Systems

Automated bending systems mechanize the bending process, allowing for more precise sheet positioning and control over bending parameters. These systems also integrate seamlessly into flexible manufacturing systems.

Numerically controlled (NC) press brakes can program bend sequences and position sheet material with high repeatability using servo motors and linear scales. Machine vision can also be integrated for online bend parameter analysis.

Modern robots either perform air bending by pulling held sheet edges using coordinated grippers or use parallel mechanical linkages to hold flat stock during stroke bending. Mechanical automation enables variable part programs, integration into welding and assembly lines, and lights-out production.

Advanced systems like continuous bending utilize a rotational draw mechanism for continuous sheet feed and bending, improving throughput. Force sensors provide real-time load data for process monitoring and maintenance.

In general, automated systems improve bend quality, enable mixed model production, and reduce labor requirements compared to manual bending.
