Abstract

The invention relates to a reverse parametric engineering method for the design of tools, characterised in comprising the following steps: importing an existing model [the design of the tool for the existing piece], production of a template for the existing tool, separation of the tool from the piece, cataloguing [saving in the form of a numerical database structured in the form of a catalogue], generating the existing tool using the section lines and characteristic lines, removing the original piece, parameterisation of the template of the existing tool [creation of a parameter profile on the section lines and the characteristic lines], importing the new piece, matching the parameter template to the new piece and creating the new model, in other words the new tool for the new piece.

Les procédés connus de l'art antérieur consistent à réaliser des simulations à partir d'un fichier de CAO. Un rapport est produit à l'issu des étapes de simulation mais chaque nouvelle simulation est réalisée sans prendre en compte les résultats des précédentes : il n'y a pas dans les procédés de l'art antérieur de capitalisation en fonction des travaux déjà réalisés.The known methods of the prior art consist in carrying out simulations from a CAD file. A report is produced at the end of the simulation stages, but each new simulation is carried out without taking into account the results of the previous ones: there is no capitalization in the prior art methods according to the work already carried out.
La présente invention entend remédier aux inconvénients de l'art antérieur en permettant de capitaliser sur l'expérience acquise et de réutiliser les travaux déjà effectués.The present invention intends to remedy the drawbacks of the prior art by making it possible to capitalize on the experience acquired and to reuse the work already carried out.
A cet effet, l'invention concerne, dans son acception la plus générale un procédé paramétrique d'ingénierie inverse pour la conception d'outillage, caractérisé en ce qu'il comporte les étapes consistant à :To this end, the invention relates, in its most general sense, to a parametric reverse engineering process for the design of tooling, characterized in that it comprises the steps consisting in:
• importer un modèle existant [la conception d'outillage existant pour la pièce existante] ;• import an existing model [the existing tool design for the existing part];
• réaliser un gabarit de l'outillage existant : séparer l'outillage de la pièce ; cataloguer [ sauvegarder dans une base de données numériques structurée sous forme de catalogue ] la création de l ' outillage existant en utilisant des lignes de section et les lignes caractéristiques ; retirer la pièce originale ;• make a template of the existing tool: separate the tool from the part; catalog [save in a digital database structured as a catalog] the creation of the existing tool using section lines and characteristic lines; remove the original part;
• paramétrer le gabarit de l'outillage existant [création d'un profil paramétrique sur les lignes de section et les lignes caractéristiques] ; • importer la nouvelle pièce ;• configure the template of the existing tooling [creation of a parametric profile on section lines and characteristic lines]; • import the new part;
• faire correspondre le gabarit paramétrique avec la nouvelle pièce ;• match the parametric template with the new part;
• créer le nouveau modèle, c'est-à-dire le nouvel outillage pour la nouvelle pièce.• create the new model, ie the new tooling for the new part.
Selon une première variante, l'étape consistant à faire correspondre le gabarit paramétrique avec la nouvelle pièce est réalisée de façon automatique.According to a first variant, the step consisting in matching the parametric template with the new part is carried out automatically.
Selon une seconde variante, l'étape consistant à faire correspondre le gabarit paramétrique avec la nouvelle pièce est réalisée de façon interactive.According to a second variant, the step consisting in matching the parametric template with the new part is carried out interactively.
On comprendra mieux l'invention à l'aide de la description, faite ci-après à titre purement explicatif, d'un mode de réalisation de l'invention, en référence aux figures annexées :The invention will be better understood using the description, given below for purely explanatory purposes, of an embodiment of the invention, with reference to the appended figures:

Le procédé selon l ' invention permet de concevoir le dessin de la nouvelle matrice en travaillant sur les conceptions d' un outillage existant et d'une nouvelle pièce .• Figures 4, 5 and 6 illustrate the reverse engineering process according to the invention. The method according to the invention makes it possible to design the design of the new matrix by working on the designs of an existing tool and of a new part.
La méthodologie de fabrication d' une matrice est représentée figure 2.The methodology for manufacturing a matrix is shown in Figure 2.
Les données à fournir en entrée pour mettre en œuvre le procédé selon l'invention sont :The data to be supplied as input for implementing the method according to the invention are:
• la nouvelle pièce• the new room
• l'outillage existant pour la pièce existante. On décompose ensuite l'outillage existant en traçant d'une façon automatique notamment la ligne d'entrée de la matrice et en reconstruisant les profils.• the existing tools for the existing part. The existing tooling is then broken down by automatically drawing in particular the entry line of the matrix and by reconstructing the profiles.
Une autre étape consiste à re-composer la nouvelle matrice en utilisant les différentes entités paramétriques (Profils, surface serre-flan, etc.)Another step consists in re-composing the new matrix using the different parametric entities (Profiles, surface hold-down blank, etc.)
