This paper outlines a conceptual framework of STEP-NC manufacturing system, which integrates the entire manufacturing process including CAD, CAPP, CAM and CNC, to make full use of the advantages of the new generation of data model. The STEP-NC manufacturing system consists of five parts and the STEP-NC standard is used to transport the complete product information. The intelligent CNC in this system can parse STEP-NC program directly so that no translation is needed and the part programs are reusable. Networked manufacturing can be realized by implementing this new framework of STEP-NC manufacturing system.

In this paper, we present a conceptual framework for designing and implementing an intelligent CNC system. The architecture and functional modules are derived from requirement analysis, and they are designed to have a thinking capability before, during, and after the execution of the manufacturing task, so that the assigned task can be effectively executed while dealing with unexpected changes occurring on the shop floor. Also, the data model for supporting the architecture is addressed based on the STEP-NC data model or ISO 14649. The framework presented can be used as a paradigm for new generation intelligent STEP-compliant CNC.

Geometric Tolerances

Tolerance information plays a critical role in many steps of the product life cycle. It is especially important due to the advances in Internet technologies and increasing integration requirements from industry. In this paper, geometric tolerances information in manufacturing process (IMP) is studied, and the layered conformance level of geometric tolerances is established according to ASME Y14.5-1994, STEP and DMIS. An EXPRESS-G data model of geometric tolerance information in IMP is established. The XML language is used to represent and program the geometric tolerances information in IMP.

Abstract This study develops a method to capture the broadest customer preference in a product line while minimizing the life-cycle cost of providing variety. The paper begins with an overview of product variety and its importance in overhead costs: supply chain, equipment and tooling, service, and recycling. After defining the product structure graph as a representation of variety, the paper introduces an approximate measure for the customer importance and life-cycle cost of product variety The cost measure utilizes the concept of late point identification which urges standardization early in the manufacturing process and differentiation at the end of the process. The variety importance-cost map allows engineers to identify cost drivers in the design of the product or the manufacturing system and seek improvements. The refrigerator door example illustrates the concept. On-going work seeks to validate and enhance the method with several companies from different industries.

Online Search Behavior

The continued success of online shopping will be determined by the degree to which consumers utilize the Internet during their decision making process, mainly the acquisition of product information. This chapter addresses consumers’ goal-directed information search in the online marketplace. To understand consumer search behavior in this unique environment, relevant theoretical perspectives are drawn to provide a conceptual framework that provides an explanation of consumers’ online search behavior. In an environment characterized by human-computer interaction, the framework includes consumers’ choice to search information online and two sets of variables – domain and system (personal) and interruptions and information load (system), affecting information search between and within Web sites. Several implications of this conceptual framework are also discussed.

This chapter examines how e-CRM has affected both organizational and individual behavior in a leading Canadian bank. The innovative and customer-driven culture of this bank pushed it toward early adoption of e-CRM technology. The findings emphasize the role played by many strategic and organizational dimensions in the success of e-CRM implementation. In fact, to make e-CRM efforts pay off, new business processes are required to achieve more effective and closer interactions with customers. The shift toward customer orientation needs to be supported by a shift in organizational objectives and processes. The results indicate that employees’ individual behavior successfully changed from a transactional to a relational perspective, and that training and coaching ensured a successful integration of e-CRM technology. Nevertheless, the employee reward and evaluation system, which should have been changed to leverage CRM impact, has surprisingly been forgotten. This deficiency is addressed by proposing a new framework for enhancing e-CRM effectiveness.

Modern Technologies

Modern technologies enable traders to design more personal and comprehensive product labelling, as well as to improve product traceability through the supply chain. Personalised and comprehensive product information could raise consumers’ product awareness, shaping new consumers’ product and safety expectations. The improved product traceability through the supply chain could extend the producers’ control over the product, beyond the moment the product left the manufacturing process. This paper examines the impact of modern technologies on European rules of product liability. Specifically, it considers whether the recognition of a defective product in the currently reviewed Product Liability Directive should continue to follow the test of the public’s safety expectations, as well as whether producers could continue to rely on the defence of a product not being defective when they put it into circulation.

This paper analyzed the heterogeneous product information for industrial cluster. It plays an important role in collaboration of enterprise and product information inquires in industrial cluster. The paper presented globe product data model based on PLIB standard. The globe classification structure and properties definition were given as the globe ontology for industrial cluster. The product class was expressed by general model class and function model class. The class is defined with the properties. The class and properties for injection machine were described as an example. According to the globe product data model, the integration framework can make the integration of heterogeneous product information and provide the unique inquire interface for the end customer. The integration framework was presented and analyzed.

Vibration Signatures

Analytical and experimental vibration analyses are conducted for a lathe system to detect the possibility of faults and develop an accurate cutting process. The data acquisition system utilized for this purpose processes the analog input from the manufacturing system and displays the response in both the real time and frequency domains. The vibration signatures for different arrangements are recorded to determine the dynamic characteristics of the system which includes work pieces, tool, and lathe components. These vibration signatures were analyzed to determine cause of inaccuracy in the manufacturing process and the faulty components. In this study, two major problem causing sources were identified using vibration analysis for the system under different operating conditions. In addition to the identified problems, the phenomena of cutting tool chatter with various intensities was examined and recorded during testing. In this study the best possible operating conditions for a specific turning process were determined using vibration analysis. Problem causing components for several case studies (different speeds, feed rates, and tool lengths) were identified and guidelines for improving a typical manufacturing process were recommended.

According as the demand of miniature metal balls of various diameter increases, processing property and a variety of coverage are important. In this study, especially an optimal groove design of cutting roller was investigated for determining size and shape of metal ball in the manufacturing system. The effects of radius of the groove and radius of the knife-edge of cutting roller and the speed of roller as process parameters were calculated and analyzed. We applied data of rigid-plastic FEM Simulation with DEFORM3D and ANSYS in basic design of equipment to solve these issues, and checked processing parameter about metal balls manufacturing process that use cutting process of metal wire stock in this research. This paper deals with the new improved process of producing miniature STS316L steel balls continuously. Our first goal is to develop a much more efficient equipment and a much more economical production process
