a functional approach for the formalization of the fixture Design Process
International Journal of Machine Tools & Manufacture, 2006Co-Authors: R Hunter, J Rios, Jesus M Perez, Antonio VizanAbstract:Abstract The Design of machining fixtures is a highly complex Process that relies on Designer experience and his/her implicit knowledge to achieve a good Design. In order to facilitate its automation by the development of a knowledge-based application, the explicit definition of the fixture Design Process and the knowledge involved is a prior and a fundamental task to undertake. Additionally, a fundamental and well-known engineering principle should be considered: the functional requirements and their associated constraints should be the first input to any Design Process. Considering these two main ideas, this paper presents the development undertaken to facilitate the automation of the fixture Design Process based on a functional approach. In this context, the MOKA methodology has been used to elicit fixtures knowledge. IDEF0 and UML have been used to represent the fixture Design Process. A methodology based on the function concept and aiming to formalize such Design Process is proposed. Fixture functional requirements have been defined and formalized. Functional fixtures elements have been used to create a functional Design solution, the link of these elements with the functional requirements and with typical commercial fixture components has been defined via tables and rules mapping. And finally, a prototype knowledge-based application has been developed in order to make an initial validation of the proposed methodology.

knowledge model as an integral way to reuse the knowledge for fixture Design Process
Journal of Materials Processing Technology, 2005Co-Authors: R Hunter, Jesus M Perez, Antonio Vizan, J RiosAbstract:Abstract The fixture Design is considered a complex Process that demands the knowledge of different areas, such as geometry, tolerances, dimensions, Processes and manufacturing resources. Nowadays, the fixture Design Process is oriented to automated systems based on knowledge models. These models describe the characteristics and relationships of the physical elements together with the inference Processes that allow carrying out the activity of fixture Design. With the employment of the knowledge models, besides the automation, it is possible to systematize and structure the knowledge of the fixture Design Process. With the use of specific methodologies, as the knowledge template, it is possible to reuse the knowledge represented in a model, for its use in a different Design Process. The knowledge template represents a pattern that defines the common entities and inference Processes to use in the Design Process. In this work, with the use of knowledge template we propose the reuse of the knowledge described in the Design Process of fixtures for machining to other types of fixtures uses like inspection, assembly or welding.

Design Process Error Proofing: Failure Modes and Effects Analysis of the Design Process
Journal of Mechanical Design, 2007Co-Authors: Lawrence P Chao, Kosuke IshiiAbstract:This paper presents a new application of failure modes and effects\nanalysis (FMEA) on Design Processes. Our research develops\nerror-proofing methods for the product development Process to prevent\nserious Design errors that can compromise project features, time to\nmarket, or cost. Design Process FMEA is a systematic method which allows\nproduct development teams to proactively predict potential problems. The\nmethod decomposes the Design Process into six potential problem\nareas-knowledge, analysis, communication, execution, change, and\norganization errors-with a question-based FMEA approach. The paper\nexplains the method, illustrates it through a case study, and discusses\nits effectiveness. The paper concludes with the proposed work to address\nDesign Process error-proofing solutions.

Design Process error proofing failure modes and effects analysis of the Design Process
ASME 2003 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference, 2003Co-Authors: Lawrence P Chao, Kosuke IshiiAbstract:This paper presents a new application of Failure Modes and Effects Analysis (FMEA) on product development Processes. Our research develops error-proofing methods for product development Processes to prevent serious Design errors that compromise project features, time, or cost. Design Process FMEA categorizes Design errors in six areas: knowledge, analysis, communication, execution, change, and organization errors. The paper explains the method, illustrates it with an example, and discusses its effectiveness. The paper concludes with the proposed work to address the existing lack of a systematic approach to Design Process error-proofing.Copyright © 2003 by ASME
