Collaborative design review in a distributed environment

Le — Wed, 28 Jun 2006 12:39:06 +0000

Abstract:

This paper investigates how collaborative environment technology can be used to integrate geographically dispersed design teams and other technical and non-technical members from within and outside the organisation to support collaborative product design reviews. The creation of such a collaborative environment for design will allow participants from different phases of the product development cycle to collaborate and form a virtual team. A new framework is proposed to extend the current advances in collaborative technologies to provide access to local and global resources within design teams and the deployment of private and public design review workspaces to provide an efficient collaborative design environment. Also, a prototype collaborative CAD environment has been developed and the results are discussed in this paper.

Machining of large dies based on the prediction of the press/die deformation

Le — Wed, 28 Jun 2006 12:36:16 +0000

Abstract

In this work a methodological scheme for a reduction of both the try-out and lead-time of complex dies is presented. The finite element simulation of the tool behaviour along the stamping process results in criteria for the best design of high-cost dies/punches. Using it, modifications of the main geometry, components and functional parameters are recommended. Examples are deeply explained as experimental evidences.

BM_Virtual Enterprise Architecture Reference Model for Concurrent Engineering and product improvement: An experiment

Le — Wed, 28 Jun 2006 12:45:41 +0000

Abstract:

In order to test the potential of Virtual Enterprise (VE) organizational principles for Concurrent Engineering (CE) team work organization, an experiment applying the BM_Virtual Enterprise Architecture Reference Model (BM_VEARM) is organized. Three CE teams are asked to create a web site. The teams have been organized as follows: 1) CE distributed team (virtual team according to literature); 2) CE agile team (agile organization according to BM_VEARM) and 3) CE virtual team (virtual organization according to BM_VEARM), in order to complete the reqired task. The principal objective of the experiment is to show that the three organization models of the CE teams work effectively and analyse the performance of each one according to previously defined criteria. In this paper the results of product quality are presented. The experiment has shown that better product quality, for the product quality aspects analysed, is achieved in cases when VE organization is applied.

Learning and Reasoning Techniques for Automatic Feature Recognition from CAD Models

Le — Wed, 28 Jun 2006 12:33:21 +0000

Abstract

During the product development, Automatic Feature Recognition (AFR) techniques are an important tool for achieving a true integration of design and manufacturing stages. In particular, AFR systems offer capabilities for the identification in Computer-Aided Design (CAD) models of high-level geometrical entities, features that are semantically significant for manufacturing operations. However, the recognition performances of most of the existing AFR systems are limited to the requirements of specific manufacturing applications. This paper presents a new AFR method that facilitates the deployment of such systems in different application domains. In particular, the method provides a formal reasoning mechanism that combines the advantages of inductive and deductive techniques for feature recognition from Boundary Representation (B-Rep) part models. The proposed AFR method is implemented within a prototype feature recognition system and its capabilities are verified on a benchmarking part.

Evolutionary Approach to Measure Production Performance

Ebubekir — Mon, 26 Jun 2006 16:35:43 +0000

In order to compete on global markets today’s production needs to keep track and continuously optimize its performance. It is crucial for a performance measurement system to enable to a general survey fast, so that trends can be identified timely in advance. Generally a broad set of performance indicators forms the basis of such a system. By combining these measures with benchmarking and target-setting a successful system for assessing and improving performance can be established. The BETTI® Benchmark (Benchmark Tool to Improve the Production Performance) is such an exemplary performance measurement system. In order to increase its effectiveness it has recently been extended by continuously including the experience and knowledge attained in previous benchmarks into the analysis. Additionally it allows appraising the consequences of actions targeted at improving production performance.

Optimization of friction stir welds of aluminium alloys

charles — Tue, 27 Jun 2006 11:29:56 +0000

The effect of rotating and welding speed on the mechanical properties of AA6056 joints made by Friction Stir Welding are investigated. Different welds with rotating speed of 1000 and 1600 RPM and travel speeds of 230, 325 and 460 mm/min were produced. An ultrasonic (UT) non-destructive testing (NDT) procedure was applied to characterize the presence of possible weld defects prior to mechanical destructive testing. The joint mechanical properties were evaluated by means of static tensile tests and fatigue tests. Both static and fatigue properties show an appreciable improvement as both travel and rotating speed increase. However, in the case of maximum travel speed and maximum rotating speed, the welded specimens may display weldment defects that reduce the evaluated fatigue limit for such processing conditions. The correlation between process parameters and weldment static properties was carried out through an analysis of variance (ANOVA) of the data.

Keywords

I notice that the Keywords feature has been um...er.. backgrounded.

Some co-chairs seem to have decided to include the keywords as an ordered list. What do you reckon about this? Is it w
