Progressive Die Design

This paper describes how a knowledge-based system for automating the process planning of progressive die design is enhanced and developed into a tutoring aid for tool and die trainees. This is achieved by incorporating an explanation engine that scans the status of the plan stored in the knowledge-base and provides reports to the user. According to the status of the plan, actions are suggested by the explanation engine to guide the user to achieve his goals. As the system is able to provide a ‘first-guess’ solution to each step of the planning process, it allows the trainee to develop the plans very quickly. It also serves as an effective tutoring aid for learning a large number of die design case studies within the time allocated for the subject.

Progressive Die Design

We discuss the cognitive aspects of skills training in progressive die design, and the ways to incorporate them into the ITS. We also give an overview of the IPD progressive die design system and explain how the design knowledge base can be exploited for development into an ITS. In this paper, we describe IPD_ITS, the tutoring module of IPD and explain its implementation for burring.

Knowledge Based

This paper presents a low cost knowledge based system (KBS) framework for design of bending die. Considerations for development of KBS are discussed at some length. The proposed framework divides the task of development of expert system into different modules for major activities of bending die design. The procedure of development of KBS modules is also described at length. Production rules for each module are recommended to be coded in the AutoLISP language and designed to be loaded into the prompt area of AutoCAD or through user interface created using Visual Basic. Each module of the proposed framework is user interactive. Development of one module of the proposed framework is also described at length. This module is capable to assess manufacturability of bending sheet metal parts. An illustrative example is also included to demonstrate the usefulness of this module. The proposed system framework is flexible enough to accommodate new acquired knowledge. As the proposed system is implementable on a PC having AutoCAD software, therefore its low cost of implementation makes it affordable even by small scale sheet metal industries.

Abstract This paper presents the use of a knowledge-based system to provide the link between computer-aided rule-of-thumb procedures and a finite element simulation package for the design of forging dies. The knowledge-based system automates the mesh generation and regeneration procedure that is traditionally the most cumbersome aspect of such a process. The system is programmed in Prolog, C, and Fortran. It is based on parametric mapping approach and generates 2-D quadrilateral meshes. Results are presented to show its effectiveness in reducing the effort and skill required for conducting forging simulations.
