摘要:

Today, industrial enterprises are facing a large number of demands from the market, technology, legislation and society. The major aspects of these influences and their effects will be described in this contribution. Using examples from the most varied areas of an enterprise and the tasks to be performed, an attempt is made to point out the path to the factory of the future.

摘要:

Production contributes to the increase of ordered complexity. Quantitative growth in energy or other resource consumption may, beyond certain thresholds, be unimportant, if not destructive to ‘production’ in that sense. In certain cases, an equivalence can be stated between production and negative consumption. High efficiency in the use of energy and environmental resources is becoming an indicator of technological progress. High productivity leads to the need for redistributing work. Leisure work becomes more indicative of personalities than stupid professional work. Individual combinations of work elements (both paid and unpaid) rather than standardized professions will characterize people in the future.

摘要:

The technological evolution which contributed to the early development of integrated computerized manufacturing systems (ICOMS) is presented and the significance and characteristics of U.S.A. manufacturing are illustrated. The human aspects in the design and use of manufacturing systems are outlined. Some solutions to human issues in ICOMS are mentioned.

摘要:

The paper describes, following three case studies, the procedure and methodological aids used for planning and realization of a computer-assisted manufacturing island for turning and drilling of rotational parts, and an FMS for rotational parts in the automotive industry which have been realized or are currentlv under construction. Further, the results are analysed in terms of technical performance and economic evaluation. Additionally discussed are some hard-to-quantifv features of the mentioned FMS which must be emphasized to keep pace with the requirements of more competitive production. The paper concludes with recommendations for the proper steps toward flexibly automated production.

摘要:

Utilizing traditional machinery, sheet metal parts are usually produced in large hatches, decreasing lot sizes and fast changing demand calls for highly flexible production systems. In spite of their rather high system cost, high power laser production systems could prove profitable on account of their big advantages in terms of flexibility. A uniquely flexible manufacturing system was planned for a broad spectrum of 3-dimensional sheet metal parts. Throughout the planning and conceptual phase, different system structures were analysed, particularly material flow through the whole system, then handling of different parts, jigs and fixtures along with their inherent flexibility and. of course, the laser systems themselves. Unconventional solutions were put forward as an answer to a unique problem. A laser may be easily acquired, but not a turn-key working station and in no case a complete flexible manufacturing system for widely varied tasks.

摘要:

In the material flow sector, there is a great potential for rationalization which should be taken advantage of. In this report, modular elements for automated material flow in manufacturing— particularly in flexible manufacturing cells and systems—are presented and explained in the form of concepts for systems. The technical design and the implementation of these material flow components are illustrated on the basis of flexible manufacturing systems already built or in the planning stage.

摘要:

This paper deals with the problem in designing an efficient production system where perishable raw materials are to be professed into several kinds of end-products. This model can clarify the relationship between the production capacity and the buffer inventory of end-products that are able to control, within their acceptable limits, both the decaying loss of harvested raw materials and the out-of-stock level of end-products.

摘要:

More than ever before, the competitiveness of industrial companies with small batch production depends on their efficiency and flexibility in manufacturing, Classical methods of rationalization are available to all branches of industry. These methods still have their justification, but they are not sufficient to ensure lasting augmentation of productivity. Up to now, the productive output per employee was increased mainly by work simplification and mechanization. In order to obtain the required increase in efficiency now and in the future, automation and integration techniques have to be utilized to a higher degree.

摘要:

In the past considerable know-how has been generated with respect to dimensional accuracy and the surface finish of machined workpieces, however, efficient methods are lacking for the improvement of the geometrical form generating capabilities of machine tools. In this paper a forecasting compensatory control scheme for the reduction of form errors in machining is presented. The approach considerably departs from traditional methods since it does not require a high precision machine tool for the achievement of high precision results. The basic underlying idea is to make use of advances in computer. sensor and actuator technologies in connection with on-line system identification methods, to implement a forecasting compensatory controller. The error motion component signals are sensed on-line by a microcomputer which develops a stochastic difference equation of error motion which in turn is used to forecast the future relative, displacement between tool and workpiece forming the basis for a proper compensatory action. The feasibility of the method is demonstrated on examples of roundness and straightness control in grinding and milling respectively.
