EU-China collaboration in design: research in Web-enabled collaborative design supported by the Asia-Link and Asia IT&C projects

The research of Web-enabled collaboration in total design supported by the European Union's Asia Link project [1] and Asia IT&C project is reported in this paper. The two projects both aim at enhancing research collaboration between the EU and China. The Virtual Research Institute (VRI) is described first, which is the platform for the collaboration for the Asia Link project and is established by utilizing the advanced Web techniques; and then, the framework for the collaboration and the Web techniques involved in the research are presented which represent the major research of the Asia IT&C project. The effective collaboration between the project partners and the impacts of the project outcome on the partnership are also discussed

Configuring A Mini-Laboratory and Desktop 3-Axis Parallel Kinematic Milling Machine

Configuring new machine tools is a complex task that involves the use of a large range of conceptions, methods, models, virtual prototypes and simulations. This paper presents a methodology for configuring a new machine tool to the level of a virtual prototype by using CAD configurator Pro/WEB.Link and a top-down approach. This methodology is explained via an example of the development of a mini-laboratory and desktop 3-axis parallel kinematic milling machine (PKMM). The results are two variants of the virtual prototype and one real world prototype. The configured virtual prototypes are used for the verification of the machining program and programming system using machining simulation in the CAD/CAM environment. The mini-laboratory and desktop 3-axis PKMM has been verified by the successful machining of test workpieces

Functional architecture and specifications for Tolerancing Data and Knowledge Management

Part 1: Knowledge ManagementInternational audienceThe paper deals with the Computer-Aided Tolerancing and Product Data Management. It is especially focus on data and knowledge management system to support and improve the tolerancing tasks in product development process. The first part of the paper introduces an overview about the recent developments related to tolerancing supports and data management systems. Based on a literature survey and industrial issues, the second part proposes a functional architecture and specifications of the data and knowledge manage-ment system addressing the numerous needs clarified by tolerancing experts

A new CNC programming method using STEP-NC protocol

Novi metod programiranja numerički upravljanih mašina alatki, koji se javlja kao alternativa G kôdu (po standardu ISO6983), je protokol AP238, ili STEP-NC, po standardu ISO10303. U radu je dato poređenje klasičnog (G kôd) i novog načina programiranja (STEP-NC), struktura opreme potrebne za novi metod programiranja, struktura programa i aktuelni scenariji za primenu protokola STEP-NC. Verifikacija navedenih scenarija realizovana je kroz tri primera.A new programming method of CNC Machine tools, which is developing as an alternative to G code, is AP238 protocol or STEP-NC, according to ISO 10303 standard. In this paper, a comparation between classical (G code) and new way of programming (STEP-NC ) is given. A structure of equipment needed for new programming method, program structure and current scenario for implementation of STEP-NC are shown. Verification of the above scenarios using the STEP-NC, is realized through three examples
