Abstract

Discusses the issue of computer‐aided design/computer‐aided manufacturing (CADCAM) integration from an organizational point of view. The installation of cross‐functional integrating technology in manufacturing organizations involves technical problems related to hardware, software and database interfacing, as well as data exchange and communication requirements. Such technical problems are perhaps more obvious and widely recognised than the organizational challenges involved in the process of organizational change that accompanies implementation. This paper uses a case study approach to analyse data gathered from two UK manufacturing companies over a five‐year period. The aim here is to compare and contrast the experiences of the two companies with a view to explaining how organizational processes contribute or otherwise to the adoption of CADCAM integration as a business strategy. A conceptual model is devised to analyse the data from the cases using a grounded qualitative research methodology. It is concluded that the crucial technological change competencies are political rather than either technological or economic. Some tactical elements of these are elaborated from the case studies.

Abstract

Describes the use of welding robots for making bridge panels. The system uses a total of 14 sets of High Speed Rotating Arc welding robots and newly‐developed arc sensor techniques are used with both joint end and bead end sensors. A teaching‐less direct CADCAM system was developed to control the robots. The welding robot system is now in commercial operation with welding efficiencies that are twice those possible with conventional processes.

Abstract

ON the shop floor at Dowty Fuel Systems' Cheltenham factory, multi‐axis CNC (computer numerically controlled) machine tools produce the main bodies of the digital engine control system for Pratt & Whitney's PW305 engine. These advanced machines are now controlled directly from the Matra Datavision EUCLID‐IS CADCAM system, following a major advance towards computer integrated manufacture.

Abstract

Discusses the adoption of CADCAM techniques by US manufacturers in the struggle for business survival with reference to case examples. Argues that CADCAM software offers valuable advantages over traditional design/manufacturing methods, principally lack of mistakes in initial production, and the reduction of both decision and design times by drastic amounts. Concludes that the attribute of speed which makes CADCAM such an advance is what is required by US companies to stay alive.

Abstract

Advanced computing systems must be employed for aerospace companies to remain competitive and reduce time scales for the introduction of new technology. In this article Dr Mike Williamson describes the advantages gained by a user, and examines the influence of aerospace requirements on the past and future development of computer aided design and manufacturing (CADCAM) techniques.

Abstract

Discusses a proposed model which presents various possible modes of behaviour during the implementation of advanced manufacturing technology (AMT) and highlighting different interaction approaches between suppliers and users of technological innovation. Presents three models of interaction processes covering different technological settings and argues for their limited applicability in the context of AMT innovation. Discusses the proposed model and its applicability to a wide range of organisational settings and covering different types of technological systems of varying degrees of complexity. The model is based on a comprehensive research project. This is based on empirical evidence originating from the study of 30 organisations representing ten suppliers and 20 users. By scrutinising the various modes of interaction during the implementation of various technological innovations, various key factors have been highlighted, which are thought to be influential in the degree of success or otherwise for the implementation of AMT. In all, seven different types of innovation were scrutinised, including: plastics injection moulding machines; CNC machines; computerised information systems; flexible manufacturing systems; material handling and supply; CADCAM; automated control systems.

Abstract

Provides a short history of the biggest collaborative research project on rapid prototyping in Europe – Computer‐Aided Rapid Prototyping (CARP) – which is concerned with the concept of design and manufacture “right first time”. Introduces the organizations involved with the project, and discusses some of the results, including the manufacture of functional components from rapid prototype models. Discusses some of the issues relating to data transfer and the limitations of CAD. Finishes with a view of how the technology is evolving and how and where it might be applied in the near future.

Abstract

Discusses various modes of interaction between suppliers and users of advanced manufacturing technology (AMT) and is based on empirical evidence originating from the study of 30 organizations representing ten suppliers and users. Highlights various key factors by closely scrutinizing the various modes of interaction during the implementation of various technological innovations. Notes that these factors are highly influential in the degree of success or otherwise for the implementation of AMT. In all, examines seven different types of innovation. These are: plastics injection moulding machines, CNC machines, computerized information systems, flexible manufacturing systems, material handling and supply, CADCAM and automated control systems. Reviews some relevant studies and discusses the critical factors in the diffusion of AMTs. Considers the benchmarking of the AMT’s implementation and finally, discusses the factors which determine the effectiveness of supplier‐customer interaction for the implementation of AMT.

Abstract

Considers the development of the automatic cutting tool selection system. Examines how the advent of knowledge‐based expert systems and CAD popularity has enabled wider availability of manufacturing process information, and the knowledge requirements for specifying optimal cutting tools in manufacturing environments where the number of machining operations makes the problem complex. Concludes that an ACTS expert system module can offer possibilities of total design systems when combined with CADCAM.
