The correct selection of process parameters for manufacturing is one of the most important aspects taken into consideration in the majority of manufacturing processes and particularly, in process related to EDM. The machining characteristics are greatly influenced by the nature of dielectric used during micro-EDM. The present paper investigates the fuzzy logic model for micro-electrical dischar...

Ultrasonic elliptical vibration cutting has recently been utilized in industry for finishing of various precision parts such as mirror surface finishing and precision micro machining of dies and molds. However, its application has been limited to high-cost ultra-precision machining, where depth of cut is typically in a range from a few micrometers to several tens of micrometers due to power lim...

The effective creation of Virtual Enterprises emerges of a previous work and environment called recently as Virtual Organisations Breeding Environment. The framework here proposed is one of the results of five years research project in the field of Collaborative Network Organisations. This paper describes a framework to create and support the Virtual Enterprises life cycle in the mould and die ...

Wire electric discharge machine (WEDM) is spark erosion in unconventional machining technique to cut hard and the conductive material with a wire as an electrode. The blanking die material SKD 11 is a high carbon and high chromium tool steel with high hardness and high wearing resistance property. This tool steel has broad application in press tools and dies making industries. In this research ...

Woven fabric reinforced composite materials are typically applied in plate or shell structures, such as ribs, stiffeners and skins. Products of this type can be manufactured with several processes. A few examples are compression moulding, diaphragm forming, matched metal die forming and Rubber Press Forming (RPF). Shape distortions can occur during manufacturing of composite products. During th...
