Using a Design Repository to Drive Concept Generation
(The American Society of Mechanical Engineers (ASME), 2008)This paper describes how a design repository can be used as a concept generation tool by drawing upon archived function-based design knowledge. Modern design methodologies include several types ... -
An Efficient Sensing Localization Algorithm for Free-Form Surface Digitization
(The American Society of Mechanical Engineers (ASME), 2008)We present a divide-and-conquer method that efficiently finds a near-optimal distribution of sensing locations for free-form surface digitization. We formulate a next-best-point problem and transform ... -
Creation of Body Surfaces From Reverse-Engineered Components
(The American Society of Mechanical Engineers (ASME), 2008)In the automotive industry or in similar industries, body panels need to be perfectly smooth for visual and aerodynamic reasons. In some cases, the component is a hand-made body part that ... -
Freeform Deformation Versus B-Spline Representation in Inverse Airfoil Design
(The American Society of Mechanical Engineers (ASME), 2008)Freeform deformation (FFD) is a well established technique for 3D animation applications, used to deform two—or three-dimensional geometrical entities. Over the past few years, FFD technique has ... -
Special Issue on “Engineering Informatics”
(The American Society of Mechanical Engineers (ASME), 2008)Computer-aided design (CAD), intelligent CAD, engineering analysis, collaborative design support, computer-aided engineering, and product lifecycle management are some of the terms that have emerged ... -
Knowledge Transfer: From Maintenance to Engine Design
(The American Society of Mechanical Engineers (ASME), 2008)As manufacturers shift their focus from selling products to providing services, designers must therefore increasingly consider the life-cycle requirements in addition to conventional design parameters. ... -
Geometric Modeling of Fluted Cutters
(The American Society of Mechanical Engineers (ASME), 2008)Geometries of cutting tools are usually represented by two-dimensional models. This paper outlines the construction of detailed computer aided design models for a variety of fluted cutters that ... -
Automatic Detection of Tangential Discontinuities in Point Cloud Data
(The American Society of Mechanical Engineers (ASME), 2008)A point cloud data set, a dense set of discrete coordinate points scanned or sampled from the surface of a 3D physical object or design model, is emerging as a new representation format for ... -
Development of a Virtual Environment for Surface Topomorphy and Roughness Determination in Milling Operations
(The American Society of Mechanical Engineers (ASME), 2008)Surface roughness is a key parameter for determining the quality of machined parts. A graphical model for the calculation of quantitative data affecting surface roughness of machined surfaces ... -
An Approach Based on Process Signature Modeling for Roundness Evaluation of Manufactured Items
(The American Society of Mechanical Engineers (ASME), 2008)In evaluating the geometrical characteristics of mechanical part, cleverness may be added with the definition of an empirical model representing the “signature” left by the manufacturing process ... -
Product Model Preparation and Processing for Micromanufacturing
(The American Society of Mechanical Engineers (ASME), 2008)Based on the two-photon polymerization technique, an analysis of product shapes is performed so that their digital manufacturing models can be efficiently processed for micromanufacture. To describe ... -
An Algorithm for the Fast Simulation of Multicomponent Object Deformation
(The American Society of Mechanical Engineers (ASME), 2008)In this paper, a fast algorithm for the simulation of deformable objects composed of multiple components made of different materials is introduced. By using the boundary element method and ... -
Flattenable Mesh Surface Fitting on Boundary Curves
(The American Society of Mechanical Engineers (ASME), 2008)This paper addresses the problem of fitting flattenable mesh surfaces in R3onto piecewise linear boundary curves, where a flattenable mesh surface inherits the isometric mapping to a planar ... -
Evaluating Supplier Performance Using DEA and Piecewise Triangular Fuzzy AHP
(The American Society of Mechanical Engineers (ASME), 2008)Data envelopment analysis (DEA) has been widely applied in evaluating multicriteria decision making problems, which have multi-input and multi-output. However, the traditional DEA method does neither ... -
