Remote sensing, diagnosis and collaborative maintenance with Web-enabled virtual instruments and mini-servers

Optimised maintenance can reduce operating costs by demanding less resources and avoiding equipment breakdown, hence ensuring that daily manufacturing and production will not be interrupted. Web-based maintenance is one of the most efficient methods for optimising maintenance. The Web-based maintenance system that we have developed uses virtual instruments, to provide remote sensing, monitoring, and on-line fault diagnosis for equipment, together with a collaborative maintenance platform for international experts to interactively share their experiences in maintenance. Moreover, Web-based maintenance is suitable for multi-tasking and multi-user types of industrial work environments. In this paper, we summarise the methods used for Web-based remote sensing and monitoring, the design and implementation of Web-enabled virtual instruments, the architecture of the collaborative maintenance platform, and the design for the mini-servers. Each mini-server is equipped with a conventional mini-Web-server and a data acquisition (DAQ) server. With the help of Web-based maintenance, local companies can be transformed into global companies providing services to their customers anywhere and at anytime.

CNC-implemented fault diagnosis and web-based remote services

Recently, the conventional controller of machine-tool has been increasingly replaced by the PC-based open architecture controller, which is independent of the CNC vendor and on which it is possible to implement user-defined application programs. This paper proposes CNC-implemented fault diagnosis and web-based remote services for machine-tool with open architecture CNC. The faults of CNC machine-tool are defined as the operational faults occupied by over 70% of all faults. The operational faults are unpredictable as they occur without any warning. Two diagnostic models, the switching function and the step switching function, were proposed in order to diagnose faults efficiently. The faults were automatically diagnosed through the fault diagnosis system using the two diagnostic models. A suitable interface environment between CNC and developed application modules was constructed for the internal function of CNC. In addition, a suitable web environment was constructed for remote services. The web service functions, such as remote monitoring and remote control, were implemented, and their operability was tested through the web. The results obtained through this research could be a model of fault diagnosis and remote servicing for machine-tool with open architecture CNC.

A web-based advisory system for process and material selection in concurrent product design for a manufacturing environment

This paper reports the work of selecting suitable manufacturing processes and materials in concurrent design for manufacturing environment. In the paper, a fuzzy knowledge-based decision support method is proposed for multi-criteria decision-making in evaluating and selecting possible manufacturing process/material combinations in terms of the total production cost. Based on the proposed method, a prototype Web-based knowledge-intensive manufacturing consulting service system (WebMCSS) with the client-knowledge server architecture is developed to help designers/users find good processes and materials while still at the conceptual level of design. The system, as one of the important parts of an advanced design for manufacturing tool, is a concept level process and material selection tool that can be used as both a standalone application and a Java applet freely available via the Web. Interlinked with Web pages of tutorials, and reference pages explaining the facets, fabrication processes and material choices, the system performs reasoning and calculations using the process capability and material property data from the remote Web-based database and knowledge base that can be maintained and updated via the Internet. The use of the system is illustrated with an example.

A component-based product data management system

Companies today have been attempting to expand their Internet infrastructures to cope with the growth of global business environments. In modern manufacturing industries, they are migrating their legacy product data management (PDM) systems to Web-based systems (being an essential tool of eManufacturing) to use the Internet. Accordingly, recent advances in PDM technology have dealt with the use of Web-based technology. Some research and development on Web-based PDM systems has been described in the literature, but those efforts have technical limits. They are not adequately available, secure, reliable, and scalable for global enterprise services. This paper describes the design of a component-based product data management (CPDM) system for supporting global manufacturing. The CPDM system is aimed at assuring flexibility, security, stability, and maintainability by utilizing a standard architecture of J2EE technology. The CPDM system consists of three tiers based on the J2EE architecture. The first is the presentation tier implemented as JSP/servlet components to allow users to access the system through a Web browser. The second is the business logic tier, which is implemented as Enterprise JavaBeans (EJB) components to handle the core PDM functionality. The third level is the data tier, composed of a database and vault for the physical files. To develop the components of the CPDM system, a component-based development (CBD) approach is proposed. The associated component development procedure is illustrated with examples. The CPDM system is also tested for its performance.

Diagnosing the cause of operational faults in machine tools with an open architecture CNC

The conventional computerized numerical controller (CNC) of machine tools has been increasingly replaced by a PC-based open architecture CNC (OAC) that is independent of a CNC vendor. The OAC and machine tools with an OAC have led to a convenient environment in which user-defined applications can be efficiently implemented within a CNC. This paper proposes a method of diagnosing the cause of operational faults. The method is based on the status of a programmable logic controller in machine tools with an OAC. An operational fault is defined as a disability that occurs during the normal operation of machine tools. Operational faults constitute more than 70 percent of all faults and are also unpredictable because most of them occur without any warning. To quickly and correctly diagnose the cause of an operational fault, two diagnostic models are proposed: the switching function and the step switching function. The cause of the fault is logically diagnosed through a fault diagnosis system using diagnostic models. A suitable interface environment between a CNC and developed application modules is constructed to implement the diagnostic functions in the CNC domain. The results of the diagnosis were displayed on a CNC monitor for machine operators and transmitted to a remote site through a Web browser. The proposed diagnostic method and its results were useful to unskilled machine operators and reduced the machine downtime.
