Resumen
La aplicación de los procesos de estampado incremental se presenta como una técnica innovadora en los procesos de conformación de materiales en todo el mundo desarrollándose distintas variantes tecnológicas del mismo. Entre estas esta el estampado incremental por punto simple (EIPS) El presente trabajo tiene como objetivo exponer las principales características de este proceso de estampado incremental, sus aplicaciones, ventajas y limitaciones. Se analizaron los factores tecnológicos que inciden sobre el proceso destacándose entre ellos el tamaño de la herramienta, la profundidad de estampado, la utilización de lubricantes, el ángulo de conformación, velocidad de conformación, espesor de la chapa y como influyen estos en la calidad superficial de la chapa, demostrando la influencia de algunos de estos factores tecnológicos con experimentos realizados. Se relacionan las características y requisitos que deben tener las máquinas empleadas en el proceso, así como las herramientas utilizadas. Se realizó una comparación económica entre el proceso de estampado incremental y el convencional, comprobándose que el estampado incremental es un proceso más económico para pequeños lotes de piezas.
The application of the incremental forming process presents is presented an innovative technique in the material forming process worldwide, developed different technological variants out of it. Among them, it is the single point incremental forming (SPIF). This paper aims to present the main features of the incremental forming process, its applications, its advantages and its limitations. The technological factors that influence the process were analyzed, highlighting the tool size, the step size, the employment of lubricants, the forming angle, forming speeds, sheet thickness and their influence on the sheet surface quality, demonstrating the influence of some of these factors technological experiments carried. The characteristics and requirements that the machines in the process must have are related, as well as the tools used. It was also carried out an economical comparison between the incremental forming and the conventional forming process, resulting the first are as the more economical for small amounts of pieces.
