“….). -Dialog level, which manages dialog elements, is a specific technology developed in our team to manipulate geometric model [40]. -Common level which contains the common instructions to all trades.…”

DIJA PROJECT: Forging Preforms Design Using Trade Knowledge

“…It provides the user with a knowledge database that is able to save trade rules. These rules are applied when the user who designs with a new design approach called "synthetic" [1] interacts with the system. Section 2 presents the DIJA project more precisely.…”

“…The main objective of the DIJA project is to help the designer by providing him with a CAD system to help the designer with an intuitive interface and an intuitive design that are more adapted to any kind of user and any kind of trade [1]. Our system is based on a new design approach named "synthetic method".…”

“…It changes the shape of a metal to some predetermined shape by one of four specific processes, either hot or cold, or by a combination of several of these processes. These four principal types of commercial forging are: (1) drop forging in which the metal shape is formed by repeated blows from a drop or steam hammer onto a bar or billet placed between a pair of dies; (2) upset forging; (3) press forging accomplished by hydraulic presses with the deforming pressure applied for longer intervals giving opportunity for plastic flow to take place; (4) roll forging produced by two rotating rolls. Several stages are necessary to preserve metal properties.…”
