Abstract

El nuevo estándar de control numérico ISO 14649 e ISO 10303-238, conocido informalmente como STEP-NC, es ahora categorizado como el futuro de los sistemas avanzados de manufactura. STEP-NC es pensado para una nueva gama de contoladores numéricos más inteligentes, flexíbles e interoperables. Este nuevo estándar ha sido parcialmente desarrollado para los procesos de mecanizado (fresado, torneado, etc.). Sin embargo, en Manufactura Aditiva (AM) con STEP-NC el desarrollo es aún incipiente. En este contexo, el presente trabajo propone una extensión del modelo de información de STEP-NC para AM y resalta las ventajas de tal modelo. Se presenta un modelo de actividades de aplicación utilizando la nomenclatura IDEF0 para describir globalmente el modelo. Se introduce el concepto de AM-layer-feature para referenciar cada capa del modelo 3D rebanado de la parte como una feature de AM. Entonces, un modelo de referencia de aplicación en EXPRESS también es presentado. Finalmente, a parir del modelo en EXPRESS es generado un archivo de programa en STEP-NC, el cual puede ser implementado sobre un sistema de AM.
