Image-Based Surface Defect Detection Using Deep Learning: A Review Tập 21 Số 4 - 2021
Prahar M. Bhatt, Rishi K. Malhan, Pradeep Rajendran, Brual C. Shah, Shantanu Thakar, Yeo Jung Yoon, Satyandra K. Gupta
Abstract
Automatically detecting surface defects from images is an essential capability in manufacturing applications. Traditional image processing techniques are useful in solving a specific class of problems. However, these techniques do not handle noise, variations in lighting conditions, and backgrounds with complex textures. In recent times, dee...... hiện toàn bộ
CPM2: A Core Model for Product Data Tập 8 Số 1 - 2008
Steven J. Fenves, Sebti Foufou, Conrad Bock, Ram D. Sriram
The initial core product model (CPM), developed at NIST for the support of in-house research projects, has been extended to create CPM2, intended to support a broad range of information relevant to product lifecycle management. CPM2 is a generic, abstract model with generic semantics. CPM2 gives equal status to three aspects of a product or artifact: its function, its form, and its behavio...... hiện toàn bộ

Virtual reality applications are making valuable contributions to the field of product realization. This paper presents an assessment of the hardware and software capabilities of VR technology needed to support a meaningful integration of VR applications in the product life cycle analysis. Several examples of VR applications for the various stages of the product life cycle engineering are ...... hiện toàn bộ
STEP, XML, and UML: Complementary Technologies1 Tập 4 Số 4 - Trang 379-390 - 2004
Russell S. Peak, Joshua Lubell, Vijay Srinivasan, Stephen C. Waterbury
One important aspect of product lifecycle management (PLM) is the computer-sensible representation of product information. Over the past 15 years or so, several languages and technologies have emerged that vary in their emphasis and applicability for such usage. ISO 10303, informally known as the Standard for the Exchange of Product Model Data (STEP), contains the high-quality product info...... hiện toàn bộ
A Design for Additive Manufacturing Ontology Tập 17 Số 2 - 2017
Mahmoud Dinar, David W. Rosen
Design for additive manufacturing (DFAM) gives designers new freedoms to create complex geometries and combine parts into one. However, it has its own limitations, and more importantly, requires a shift in thinking from traditional design for subtractive manufacturing. There is a lack of formal and structured guidelines, especially for novice designers. To formalize knowledge of DFAM, we h...... hiện toàn bộ

Abstract
Cloud manufacturing is an emerging novel business paradigm for the manufacturing industry. In cloud manufacturing, distributed manufacturing resources are encapsulated into services and aggregated in a cloud manufacturing platform. Through centralized service management, cloud manufacturing is capable of dealing with multiple requirement tas...... hiện toàn bộ
Challenges and Status on Design and Computation for Emerging Additive Manufacturing Technologies Tập 19 Số 2 - 2019
Yuen-Shan Leung, Tsz-Ho Kwok, Xiangjia Li, Yang Yang, Charlie C. L. Wang, Yong Chen
The revolution of additive manufacturing (AM) has led to many opportunities in fabricating complex and novel products. The increase of printable materials and the emergence of novel fabrication processes continuously expand the possibility of engineering systems in which product components are no longer limited to be single material, single scale, or single function. In fact, a paradigm sh...... hiện toàn bộ
An Internet of Things-Based Monitoring System for Shop-Floor Control Tập 18 Số 2 - 2018
Dimitris Mourtzis, Nikolaos Milas, Aikaterini Vlachou
With the advent of the fourth industrial revolution (Industry 4.0), manufacturing systems are transformed into digital ecosystems. In this transformation, the internet of things (IoT) and other emerging technologies pose a major role. To shift manufacturing companies toward IoT, smart sensor systems are required to connect their resources into the digital world. To address this issue, the ...... hiện toàn bộ
Surface Reconstruction of Freeform Objects Based on Multiresolution Volumetric Method Tập 3 Số 4 - Trang 334-338 - 2003
Sergei Azernikov, Alex Miropolsky, Anath Fischer
Recently developed 3D scanning devices are capable of capturing point clouds, as well as additional information, such as normals and texture. This paper describes a new and fast reverse engineering method for creating a 3D computerized model from data captured by such contemporary 3D scanning devices. The proposed method aggregates large-scale 3D scanned data into an extended Hierarchical ...... hiện toàn bộ
A Knowledge-Based Method for Innovative Design for Additive Manufacturing Supported by Modular Ontologies Tập 18 Số 2 - 2018
Thomas Hagedorn, Sundar Krishnamurty, Ian R. Grosse
Additive manufacturing (AM) offers significant opportunities for product innovation in many fields provided that designers are able to recognize the potential values of AM in a given product development process. However, this may be challenging for design teams without substantial experience with the technology. Design inspiration based on past successful applications of AM may facilitate ...... hiện toàn bộ
