In many manufacturing processes, some key process parameters have very strong relationship with the normal or various faulty products of finished products. The abnormal changes of these process parameters could result in various categories of faulty products. In this paper, a data mining model is developed for on-line intelligent monitoring and diagnosis of the manufacturing processes. In the p...

The present manufacturing sectors are burdened with increasing speed of transitioning new global business developments into production processes. This forces the old approaches of information management to adopt better evolution capabilities. Although the concept of virtual manufacturing is to facilitate integration of production processes in global industrial organizations, its information man...

This paper presents MEDIATOR, a feature recognition system which is designed to be maintainable and ex-tensible to families of related manufacturing processes. A problem in many feature recognition systems is that they are diicult to maintain. One of the reasons may be because they depend on use of a library of feature-types which are diicult to update when the manufacturing processes change du...

Virtual reality (VR) has become an important and useful tool in science and engineering. VR applications cover a wide range of industrial areas from product design to analysis, from product prototyping to manufacturing. The design and manufacturing of a product can be viewed, evaluated and improved in a virtual environment before its prototype is made, which is an enormous cost saving. Virtual ...

In this paper we present the first part of a project of flexible manufacturing process optimisation in a Slovenian furniture company. In this part we analysed the current state of the manufacturing system by constructing a discrete event simulation model that reflects the manufacturing processes. As the manufacturing process involves about 30,000 subprocesses it is not feasible to manually cons...

This paper deals with the problem of optimizing a factory floor layout in a Slovenian furniture factory. First, the current state of the manufacturing system is analyzed by constructing a discrete event simulation (DES) model that reflects the manufacturing processes. The company produces over 10,000 different products, and their manufacturing processes include approximately 30,000 subprocesses...

The philosophy of group technology (GT) is an important concept in the design of flexible manufacturing systems and manufacturing cells. Group technology is a manufacturing philosophy that identifies similar parts and groups them into families. Beside assigning unique codes to these parts, group technology developers intend to take advantage of part similarities during design and manufacturing ...

Micro-manufacturing emerged in the last years as a new engineering area with the potential of increasing peoples’ quality of life through the production of innovative micro-devices to be used, for example, in the biomedical, micro-electronics or telecommunication sectors. The possibility to decrease the energy consumption makes the micro-manufacturing extremely appealing in terms of environment...

The global development of the world has an adverse affect on the natural environment, such as global warming, is continuing to mount. Green manufacturing systems that focus on minimizing environmental impact of manufacturing processes and products are ever more important to sustain our future. Green manufacturing systems are slow to gain acceptance as manufacturers are focusing more on implemen...

a neural network with feed forward topology and back propagation algorithm was used to investigate the effect of composition on mechanical properties in api x65 microalloyed steel (used in manufacturing of large diameter pipes). experimental data was obtained by cutting 100 specimens from pipes manufactured in industrial scale (with similar heats and manufacturing processes). the chemical analy...
