Overview of 3D printing technologies for reverse engineering product design

With the rapid development of computer and information automatics, advanced manufacturing technologies (such as numerical control technology and computer-aided manufacturing) have been invented and matured. In the face of fierce competition in the international market of 21st century, high-tech application becomes one of the main battle fields. In recent years, reverse engineering technology has developed rapidly, through which the digital computer-aided design (CAD) models of products can be obtained rapidly and accurately; in association with optimization design, computer aided design and finite element analysis, reverse engineering technology significantly improves the development efficiency of new products. As one of the representative technologies of the third industrial revolution, three-dimensional (3D) printing technology is adopted in reverse engineering to realize rapid manufacturing of products in a lot of fields; in addition, 3D printing is gradually penetrating into each link of product design, attracting more and more attention from industrial and investment communities.     

Integration of manufacturing services into virtual environments over the internet

Virtual reality (VR) is a rapidly developing technology that has a wide spectrum of industrial and commercial applications. Networked (distributed or shared) virtual environments (VE) are of growing interest to modern manufacturing industry; a dominating use of networked virtual manufacturing environments (VMEs) is on-line visualisation and collaborative control of 3D information. This has to be supported by real-time data transfer. To meet a broad range of common requirements for Internet-based VE communications, particularly for virtual manufacturing and collaborative design and control, this paper presents a networked virtual environment system that is designed to support networked virtual design and manufacturing. The system is implemented with manufacturing message specification (MMS) standards so as to integrate a range of manufacturing services into networked VEs over the Internet.

STEP-NC based high-level machining simulations integrated with CAD/CAPP/CAM

With the development of manufacturing,numerical control(NC) machining simulation has become a modern tool to obtain safe and reliable machining operations.Although some research and commercial software about NC machining simulations is available,most of them is oriented for G&M code.It is a low-level data model for computer numerical control(CNC),which has inherent drawbacks such as incomplete data and lack of accuracy.These limitations hinder the development of a real simulation system.Whereas,standard for the exchange of product data-compliant numerical control(STEP-NC) is a new and high-level data model for CNC.It provides rich information for CNC machine tools,which creates the condition for an informative and real simulation.Therefore,this paper proposes STEP-NC based high-level NC machining simulations solution integrated with computer-aided design/computeraided process planning/computer-aided manufacturing(CAD/CAPP/CAM).It turned out that the research provides a better informed simulation environment and promotes the development of modern manufacturing.     

A hybrid multi-agent system architecture for enterprise integration using computer networks

The manufacturing industries are now experiencing fierce pressure of competition from every corner on this planet. In addition, the advancement in computer networks and information technologies has been gradually reshaping the manufacturing companies by shifting from the industrial age to the information era. Due to these elevated competitiveness and advanced computer technology, a number of new manufacturing and management strategies (e.g., CE or CIM) have emerged for the innovation of manufacturing enterprises. Although they have different definitions and scopes, there are several common issues: inter-enterprise functions integration; inter-enterprise resources integration; and collaboration. This paper proposes a new multi-agent system (MAS) architecture to support the inter-enterprise functions/resources integration and collaboration over the networked environment, including the hybrid agent architecture and hybrid network architecture. In contrast to the existing agent architectures, the proposed agent architecture enables agents to exhibit the hybrid (continuous and discrete) behavior and interactions. In addition, our network architecture is more suitable for building the large-scale distributed manufacturing systems that are prone to dynamic random changes of their environment. Based on the proposed MAS architecture, a collaborative product development environment is implemented as a starting point, and a multidisciplinary team-oriented design problem is illustrated to provide the vision of the proposed MAS architecture.     

A telebiometric system mechanism model and biometric network protocol for the security of networked manufacturing

Networked manufacturing changes conventional enterprise activities. With a networked manufacturing system, enterprises are able to perform a range of activities, such as product planning, design, production, and marketing, in collaboration with international partners, regardless of geographical location. However, strict security measures are required, as the authentication and information transfers for networked manufacturing are conducted over a network. With the development of biometric technology, more and more enterprises are using the unique biometric data of individuals to verify the identity of users, in order to restrict and provide access to technology research centers or factory facilities. This paper analyzes the vulnerabilities of the biometric system used for access control and the authentication of access to confidential information in the networked manufacturing system. In addition, the biometric systems that can be built in an open network environment are classified into 9 general models, and a biometric network protocol is suggested that is secure and compatible with international standards.
