“…For example, in the die design process, the flat pattern features can be derived from corresponding sheet metal product features. This characteristic has led to the development of intelligent design automation systems for each individual step, like the IPD (Intelligent Progressive Dies) system [4]. Secondly, at the coarse-grain level, one can use modelmodel relationship to describe which model is dependent on other models to ensure global consistence during the execution of the engineering process.…”

Conventional data-centric integration approaches assume that the end-users are fully responsible for work-flow control, data consistency and integrity maintenance and inter-process coordination, generally without computer augmentation. The objective of this study is to develop a network-integrated engineering environment with an expanding set of system capabilities that can off-load engineers from some of these responsibilities and complexity, based on an integration approach which is both data-and processcentric. The envisioned system is configured on top of a generic CAX framework with a process management module encapsulated for assisting engineers to carry out a set of tightly-interrelated engineering activities in a product development cycle following a feature-driven process pattern. Sheet metal products using progressive dies were selected as the demonstration case to show two main aspects of the approach: information modeling and implementation of the process management module.

“…Researchers at the National University of Singapore have been developing an intelligent progressive die (IPD) design system since the late 1980s. They used feature modeling and rule-based approach to realize automatic punch shape selection, strip layout development, and 3-D die configuration [7,8]. Based on a feature-relationship tree that describes the stamped metal part and its topological information, model-based reasoning and spatial reasoning techniques have been employed to reason out certain stamping processes and guide the overall planning process to develop the strip layout automatically.…”

It is widely accepted that stamping process planning for the strip layout is a key task in progressive die design. However, stamping process planning is more of an art rather than a science. This is in spite of recent advances in the field of artificial intelligence, which have achieved a lot of success in incorporating built-in intelligence and applying diverse knowledge to solving this kind of problem. The main difficulty is that existing knowledge-based expert systems for stamping process planning lack a proper architecture for organizing heterogeneous knowledge sources (KSs) in a cooperative decision making environment. This paper presents a knowledge-based blackboard framework for stamping process planning. The proposed approach speeds up the progressive die design process by automating the strip layout design. An example is included to show the effectiveness of the proposed approach.

“…Due to competition in the marketplace and short product life cycle, there is a strong desire to develop a design automation system for progressive dies [8,9,10]. In progressive die design, there are two main processes associated with the use of information related to standard components: selecting standard components in given catalogues, and extracting the parameters of standard components from the catalogues.…”

This paper proposes a novel approach for standard component reuse in die design. In this approach, a standard component, or a subassembly of standard components, is represented by a unique name called the order name. The order name is derived by combining a manufacturer or supplier's name with the catalogue name used for ordering components from the supplier. In this system, the standard components are classified according to their generic information, i.e. their functions and the geometrical characteristics of their mating relationships with other components. When a user designs a particular die structure for a certain function, some design options and requirements are inputted. Using this information, the generic information of the standard component is derived and the order name is selected. The rules required for the selection procedures are stored in a knowledge-base shell. The shell is able to search data tables and retrieve parameters regarding the standard components. In this approach, the catalogue data and selection procedure are independent of the design system. It is concise and consistent with industry practice.Keywords Progressive die design system AE Design reuse AE Standard components AE Knowledge-based method Int
