  • 5. Que es la Ingeniería Inversa? Reverse Engineering (RE)En la actualidad, la ingeniería inversa es un método válido para la creación o recreaciónde nuevos productos a partir de productos existentes y a veces obsoletos, la copia demodelos sin necesidad de planos y hasta para la evaluación de conformidad demodelos CAD 3D con modelos originales o pruebas de manufactura.Ι © Dassault Systèmes Ι Confidential Information ΙAunque los nuevos sistemas de CAD facilitan eldiseño del producto, hay que desarrollar nuevasaplicaciones que permitan obtener un diseñoconfiable y funcional disminuyendo los tiemposde diseño con objeto de minimizar el incrementode coste de fabricación. 5
  • 6. Usos de la Ingeniería InversaLa ingeniería inversa es un proceso ó un método valido para la: Creación o recreación de nuevos productos (modelo/obsoleto)Ι © Dassault Systèmes Ι Confidential Information Ι Producción en serie producto (Ausencia de datos del modelo) Evaluación conformidad modelo real vs CAD (control de calidad) Reconstrucción y/o modelado superficies complejas (tipo A) Modelado CAD 3D (parametrico/no parametrico) Estudios de estilos (forma, dimensión, funcionalidad, etc…) Comparaciones con el mercado (Benchmarking) Reproducción dispositivos/herramental (desgaste moldes/troqueles) 6
