Knowledge Based Engineering

In traditional CAD technology, it is mainly to express the geometric information of parts, but can not express non-geometric information, such as weight, strength, and can not do the design of geometric distortion for changed topology. The combination of knowledge-based engineering (KBE) and CAD solved these problem in the filed of molding. NX/KF is a new technology to integrate CAD and KBE. This paper develops the mould parts with NX/KF as an example to explain its application. It analyzes the substance of parametric design and point out the developing direction of CAD by analyzing new characteristics of knowledge fusion.

Abstract The deployment of knowledge-based engineering systems is on the increase within engineering industries and, as such, there will be an ever-increasing demand to share a common product representation, which includes design and manufacturing knowledge. At the moment, each commercial knowledge-based engineering system has its own development language and therefore representation language for design and manufacturing knowledge. To date, no work has fully addressed the need to exchange product knowledge as well as product data. It is, therefore, the main aim of this paper to demonstrate the need for a standard product knowledge representation language and how it could be developed by using existing standards, thereby providing the ability to exchange product knowledge as well as product data.

Rules Maintenance

This paper reports on a system that has been developed to facilitate the structure and reuse of engineering rules (ERs) in Knowledge-Based Engineering (KBE) systems. The proposed structure for rule elements supports the traceability of knowledge sources as well as where the knowledge elements are used in KBE applications. This forms the infrastructure to systematically manage the use and reuse of knowledge and control the version and update of the rules when new knowledge is gained. Representing product knowledge in rules is a way to capture the know-why of the design by modelling the decisions involved in the design process. KBE has been used as the mechanism to deploy this knowledge. Although the KBE technology can support the management of this knowledge, the maintenance of the knowledge is often a neglected task. This leads to a number of practical difficulties in the large scale rollout of KBE applications. To design an improved KBE rules maintenance system, the research team developed a generic representation to unify the off-line storage of the IF, COND and CASE statements used in the ICAD Design Language. Additional data fields are defined to maintain the traceability of the origin and use of rules. This is implemented in a Microsoft Access database. The integration of this off-line rule repository with the ICAD KBE system is achieved and validated in an industrial application. The data structure defined and the implementation system is detailed in this paper.

Knowledge Based Engineering

In the process of designing aeronautic composite mold parts, previous designing knowledge and expertise cant be well used, the cycle of parts modeling is long and its production efficiency is low. According to the classification and characteristics of aeronautic mold parts and the knowledge engineering technology, based on the fusion module in UG6.0, we establish its repository by the knowledge acquisition, knowledge representation and knowledge reasoning of aeronautic mold parts. With the UG secondary development tools, UG/Open Menuscript and UG/Open Uistyler, we develop user menu and parametric design interface of aeronautic mold parts, make good use of its designing knowledge, and fulfill the knowledge-driven parts parametric design. They satisfy the rapid design requires of aeronautic mold parts and shorten its designing cycle.

Under the tendency of knowledge economy in the world, knowledge research becomes a hot subject. The analysis about the meanings, categories and characteristics of knowledge is presented at first. The concept and key techniques of Knowledge Based Engineering (KBE) are discussed. The differences and relationships among KBE, Expert System (ES) and CAD/CAE/CAPP/CAM (CAX) Systems are analyzed as well. An example on knowledge-based designing of one complicated product is provided. A product knowledge base is established by analyzing the structure and characteristics of product design knowledge. Product knowledge integration and management is fulfilled using Product Data Management (PDM) and dynamic database technique.

Abstract Knowledge-based engineering systems are now becoming more commonplace in engineering industry. There is a need to ensure the technology is used correctly and to provide the user with all the possible benefits that the system can offer. This paper looks at how product knowledge can be managed within knowledge-based engineering systems to ensure that the knowledge retains its value and usefulness during the product lifecycle. Presently, the use of these systems has been for the short-term benefit of the company. However, it is believed that it is important to consider longer-term issues also, since knowledge normally has a half-life of around 20 years. The main aim of this paper is to demonstrate the need for product knowledge management within knowledge-based engineering systems by looking at key issues that are related to the longer-term use of these systems. This paper will also provide a product knowledge management scheme for the development and management of product knowledge within knowledge-based engineering systems, thereby extending the benefits of knowledge-based engineering systems into the longer-term.

Cyberphysical system design automation utilizing knowledge based engineering techniques with globally networked knowledge bases can tremendously improve the design process for emerging systems. Our goal is to develop a comprehensive architectural framework to improve the design process for cyberphysical systems (CPS) and implement a case study with Axiomatic Design Solutions Inc. to develop next generation toolsets utilizing knowledge-based engineering (KBE) systems adapted to multiple domains in the field of CPS design automation. The Cyberphysical System Design Automation Framework (CPSDAF) will be based on advances in CPS design theory based on current research and knowledge collected from global sources automatically via Semantic Web Services. A case study utilizing STEM students is discussed.
