Abstract:

Increasing demand to manage and preserve 3-dimensional models for a variety of physical phenomena (e.g., building and engineering designs, computer games, or scientific visualizations) is creating new challenges for digital archives. Preserving 3D models requires identifying technical formats for the models that can be maintained over time, and the available formats offer different advantages and disadvantages depending on the intended future uses of the models. Additionally, the metadata required to manage 3D models is not yet standardized, and getting intellectual proposal rights for digital

Abstract:

Product Lifecycle Management (PLM) has become increasingly important in the engineering community over the last decade or so, due to the globalisation of markets and the rising popularity of products provided as services. It demands the efficient capture, representation, organisation, retrieval and reuse of product data over its entire life. Simultaneously, there is now a much greater reliance on CAD models for communicating designs to manufacturers, builders, maintenance crews and regulators, and for definitively expressing designs. Creating the engineering record digitally, however, presents

Abstract:

Abstract Template-Based reverse engineering approaches represent a relatively poorly explored strategy in the field of CAD reconstruction from polygonal models. Inspired by recent works suggesting the possibility/opportunity of exploiting a parametric description (i.e. CAD template) of the object to be reconstructed in order to retrieve a meaningful digital representation, a novel reverse engineering approach for the reconstruction of CAD models starting from 3D mesh data is proposed. The reconstruction process is performed relying on a CAD template, whose feature tree and geometric constraint

Reverse engineering involves digitizing a three-dimensional model or part, by means of a tactile or non-contact optical sensor, converting the data to a CAD (computer aided design) database description and manufacturing by CNC (computer numerical controlled) machines.

Three-dimensional models of the body parts were developed using the basic 3D modeling operations (rotation, extrusion, threading, etc.) of the T-FLEX CAD 3D CAD system, which made it possible to significantly simplify the work with assembly 3D models representing a complex structure consisting of a large number of parts. During the trial operation, the advantages of using the T-FLEX CAD 3D CAD system have been proven when working with complex 3D models. The advantages of using the program in the machine-building cluster are shown.

The method for analyzing shapes of a CAD model represented by triangle mesh is studied. The system can extract planar, spherical, cylindrical, hole, arc, and other curved regions.

This paper aims to highlight the utility of implementing the Reverse Engineering Technique in designing assembly parts in the field of industry. Starting from the iconic part models the project begins with the specific stages for Reverse Engineering technique, the part digitization by means of a 3D scanning system, followed by the reconstruction of the solid type parts, and ending with their parameterization. Parameterization is of great importance especially in what concerns the automated obtaining of the part models, since this allows updating the solids along with the change of parameters.

The CAD models of mechanical parts usually have many blends and chamfers, and the existence of these machining features can greatly change the geometric and topological patterns of the CAD models, but the existing partial matching algorithms cannot match the CAD models which contain machining features such as blends and chamfers. In this paper, a new approach to partial matching based on the constraints of transition features is proposed. Firstly, the transition features are identified by feature recognition, and then these machining features are removed to eliminate the impacts to the geometr

Abstract:

A generalized approach to fast interpretation of objects and their features has so far eluded researchers. In manufacturing, this interpretation can be approached from the vision point of view or from the CAD data perspective. Presently, CAD systems are widely used in several aspects of manufacturing production. It is therefore more efficient to use CAD data for object reasoning in manufacturing, especially when systems will eventually be data driven. Components can be modelled on a CAD system using various modelling techniques and the representation of their geometric information is still CAD

Abstract:

The manufacturing industry constantly needs to verify machined objects against their original CAD models. Given a prototype design, an engineer should be able to determine whether the part was manufactured well; that is, whether it fits the CAD model exactly. However, derivative computations are unstable for real data, and the estimated curvature is thus very sensitive to noise. Moreover, in many cases, spatial fitting of corresponding points is not sufficient. The current work utilizes the curvature properties to inspect manufactured parts that have been reconstructed from noisy and densely s

Abstract:

According to the requirements of integral Stereolithography (integral SL) System, a new direct slicing method with SolidWorks for integral Stereolithography System is developed. Slicing function of SolidWorks is employed to slice CAD models directly, and section image of 3D models can be obtained and saved as image format. Dynamic graphic masks for the integral SL System are created according to the cross-section images that obtained through the slicing method, and then 3D real prototyping can be fabricated conveniently. A 3D cup model is sliced with this method, and the cup prototyping also i
