5. Que es la Ingeniería Inversa?
Reverse Engineering (RE)
En la actualidad, la ingeniería inversa es un método válido para la creación o recreación
de nuevos productos a partir de productos existentes y a veces obsoletos, la copia de
modelos sin necesidad de planos y hasta para la evaluación de conformidad de
modelos CAD 3D con modelos originales o pruebas de manufactura.
Ι © Dassault Systèmes Ι Confidential Information Ι
Aunque los nuevos sistemas de CAD facilitan el
diseño del producto, hay que desarrollar nuevas
aplicaciones que permitan obtener un diseño
confiable y funcional disminuyendo los tiempos
de diseño con objeto de minimizar el incremento
de coste de fabricación.

6. Usos de la Ingeniería Inversa
La 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)

42. Como se involucra la RE en un proceso de diseño
 Tristan Adam
 Accidente a los 5 años
 Sindrome de Compartimento
 A los 9 años perdida funcionalidad mano izquierda
 Movimiento limitado de la mano y dedos
 Muñeca cerrada y doblada a un solo lado
 Mal crecimiento del brazo izquierdo
Ι © Dassault Systèmes Ι Confidential Information Ι
 Brazo izquierdo mas corto que brazo derecho
Antes…
Después…
42

43. El antes….
 Lamina metalica recubierto con protector termoplastico
 Sujetadores y ajustes de velcro
 NO funcional, solo esta adaptado a la forma de la mano
y el brazo con poca protección
