Resumen
Actualmente, diversos sectores industriales (aeronáutico, automoción,...) utilizan procesos de
conformado para producir componentes de geometrías complejas a partir de chapas metálicas. Los
procesos tradicionales de conformación que utilizan matrices son apropiados para la producción de
grandes volúmenes de piezas, pero no son rentables en el caso de series reducidas. El conformado
incremental es un proceso diferente, inteligente y flexible, que se presenta como una alternativa a
los métodos de conformado tradicionales. Este proceso se basa en metodologías de Rapid
Manufacturing, y permite reducir enormemente los costes de utillaje, ya que solo requiere de una
herramienta simple de soporte. Se adecua perfectamente a la fabricación de prototipos y series
cortas por los bajos costes de producción, pero el tiempo necesario para conformar una pieza,
típicamente varias horas, lo hace inviable para series más largas.
De la revisión bibliográfica realizada se demostró que este proceso puede ser aplicado en la industria
en la fase de desarrollo de los productos o para la producción de pequeños lotes de piezas. Se analizaron los factores tecnológicos que inciden sobre el proceso y se realizaron varios experimentos con el fin de determinar la influencia de la velocidad de rotación (rpm) y el avance (mm/min) sobre el acabado superficial en unachapa de aluminio.
Various industrial sectors (aerospace, automotive,) use forming processes nowadays to produce components of complex shapes from sheet metal. Traditional processes that use arrays are suitable for the production of large volumes of parts, but are not profitable for small series. Incremental forming is a different process, intelligent and flexible, which presents itself as an alternative to traditional forming methods. This process is based on Rapid Manufacturing methodologies, and greatly reduces tooling costs, since it only requires a simple tool support. It’s well suited to the manufacture of prototypes and small series by low production costs, but the time required to manufacture a part, typically several hours,which makes it impractical for longer runs. From the literature review showed that this process can be applied in the industry in the development phase of the product or to the production of small batches of parts. Technological factors affecting the process and several experiments to determine the influence of the rotation speed (rpm) and feed rate (mm / min) on the surface finish on the aluminum sheet were performed.
