Knowledge-evolutionary intelligent machine-tools —Part 1: Design of dialogue agent based on standard platform

During the last decade (from the late 1970s to the beginning of the 1990s), manufacturing systems have significantly changed. Their function and performance have altered in a period of rapid development, mainly as a result of the application of the techniques of computer science. The new systems are termed either flexible manufacturing systems (FMS) or computer- integrated manufacturing (CIM). The advance of flexible manufacturing and its related technologies has been accompanied by a number of related developments, such as flexible manufacturing of a global network type, CIM incorporating personnel functions, skill-based manufacturing, and compact flexible manufacturing cells (FMC). These all have notable influences on the system configuration and operational technologies of flexible manufacturing: perhaps as a result, there is some confusion about their terminology. A number of differing nomenclatures are used (such as FMC, FMS, flexible or factory automation (FA), CIM and enterprise automation (EA), for the same fundamental technology.

Integrating manufacturing resources planning (MRP II) with flexible manufacturing systems (FMS)

Rapid prototyping of complex systems and their control strategies is an important approach in system modeling, especially in early design stages. Naturally, these systems can be seen as a network of concurrently running communicating objects. A practical application field are flexible manufacturing systems (FMS) used in computer integrated manufacturing (CIM). An FMS consists of concurrently working machines which are connected by a computerized material handling system. This leads to well-known problems like scheduling and resource allocation where the usefulness of the fuzzy logic approach has been shown. Concurrent objects as a modeling paradigm enable the designer to describe the system's structure and behavior naturally on a high abstraction level. In this paper we argue that the control strategies based on complex hierarchical fuzzy rule bases fit nicely in the concurrent object based modeling view and, consequently, in a consistent design approach. Moreover, we introduce a suitable programming language (DFKI Oz), extended by a fuzzy library, which supports the described modeling approach. Validation of our approach is described by modeling a complex FMS in the field of car production.

High quality and low-cost factors are among the main components of manufacturing. Nowadays, businesses need to keep up with technological innovations in order to meet these factors and survive in a competitive environment. These require the use of high-performance computer integrated manufacturing (CIM) technologies in order to manufacture products faster, inexpensively, flexibly and more efficiently. These technologies generally include computer-aided design (CAD) and computer-aided manufacturing (CAM), industrial robotics, automated material handling systems, group technology, flexible manufacturing systems (FMS), rapid prototyping (RP) operations and computer numerical controlled (CNC) machines. The main purpose of these advancements is to provide higher labour efficiency and flexibility, lower production time and a reduction of direct labour requirements. In this chapter, the effects of CIM technologies on manufacturing processes as well as product quality will be comparatively analysed. The effect of the internet of things (IoT), cyber-physical service (CPS) and cloud computing (CC) on smart manufacturing systems, which can be operated and integrated with CIM and contribute to increasing manufacturing efficiency by using information, will be revealed in detail.

Some Managerial Issues Concerning Implementation and Maintenance of Flexible Manufacturing Systems- An Indian Perspective

A KNOWLEDGE BASED SIMULATION APPROACH FOR REAL-TIME MODEL VALIDATION

SUMMARYIn the context of computer-integrated manufacture (CIM), the paper describes the need for flexible “intelligent” machinery and the need for integrated and distributed software. Methodologies in obtaining appropriate solutions are discussed and related to two major SERC sponsored research programmes at Loughborough University, which concern (i) the design of a family of mechanical and control system modules to allow robots to be configured with user defined kinematic and dynamic properties, and (ii) the design of distributed hardware and software structures, based on internationally accepted communication protocols, to allow FAS's to be produced.In batch manufacture today's increased demand for product variety, requiring reduced lead times and work in progress, the need arises for computer-integrated manufacture (CIM). Similarly, in many conventional continuous flow manufacturing processes dramatic improvements in plant efficiency can be achieved by linking shop floor computer systems with computers performing management and design functions.Considerable research and development work has centred on flexible manufacturing systems (FMSs)3−1 which conventionally relate to metal cutting environments. Similarly the labour intensive nature of assembly operations has led to considerable interest in the design of flexible assembly systems.3.4 The principles embodied in FMS and FAS are translatable, being applicable to most manufacturing environments.To achieve flexible integrated manufacturing two major requirements can be identified, viz. (i) the need for flexible “intelligent” machinery, and (ii) the need for integrated but distributed software systems. This paper will consider future trends in (i) and (ii).

Designing products for easy assembly and disassembly during their entire life cycles for purposes including product assembly, product upgrade, product servicing and repair, and product disposal is a process that involves many disciplines. In addition, finding the best solution often involves considering the design as a whole and by considering its intended life cycle. Different goals and manufacturing plan selection criteria, as compared to initial assembly, require re-visiting significant fundamental assumptions and methods that underlie current assembly planning techniques. Previous work in this area has been limited to either academic studies of issues in assembly planning or to applied studies of life cycle assembly processes that give no attention to automatic planning. It is believed that merging these two areas will result in a much greater ability to design for, optimize, and analyze the cycle assembly processes. The study of assembly planning is at the very heart of manufacturing research facilities and academic engineering institutions; and, in recent years a number of significant advances in the field of assembly planning have been made. These advances have ranged from the development of automated assembly planning systems, such as Sandia's Automated Assembly Analysis System Archimedes 3.0{copyright}, to the startling revolution in microprocessors and computer-controlled production tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), flexible manufacturing systems (EMS), and computer-integrated manufacturing (CIM). These results have kindled considerable interest in the study of algorithms for life cycle related assembly processes and have blossomed into a field of intense interest. The intent of this manuscript is to bring together the fundamental results in this area, so that the unifying principles and underlying concepts of algorithm design may more easily be implemented in practice.

Conceptually, the ideal solution is believed to lie in the creation of a practical computer-integrated manufacturing (CIM) environment. To achieve this, the integration of computer-aided design (CAD) systems with auto-insertion and placement machines in a flexible manufacturing system (FMS) is a vital requirement.

Uniquely, this paper establishes a vision for next-generation Industry 4.0 manufacturing machines, which will exhibit extraordinary Smart and Reconfigurable (SR*) capabilities.

The transformation of desired physical effects to process settings has been achieved through extensive use of appropriate in situ sensors for the MMST program. In situ sensors like an ellipsometer can be used to monitor film thicknesses as well as etch or growth rate in real time, and to determine endpoint time. This capability is opposed to conventional processing, which uses pilot wafers and ex situ statistical process control. In situ sensors enable real-time wafer-to-wafer compensation for equipment and process drifts and also diagnosis of equipment status for preventive maintenance. This paper discusses the use of a spectral ellipsometer (SE) developed at Texas Instruments and the issues involved in the integration of this SE to the machine control as well as to the factory-wide computer integrated manufacturing (CIM) environment for feedforward and feedback control. >

The impact of computer integrated manufacturing on the first-line supervisor position is investigated. Twelve typical activities performed by the first-line supervisor were identified in an extensive review of the literature. Computer integrated manufacturing (CIM) is described as it is envisioned and reported at several existing flexible manufacturing systems in this country. The impact of CIM on the twelve first-line supervisor activities is conceptualized, and a forecasted new list of seven activities is developed. The possibility of retraining first-line supervisors for the new technology is discussed.
