introduction: countries around the world are looking for an appropriate, stable, and affordable replacement for the natural energies. therefore, the waste is considered as an available resource to produce energy, which by controlling, its effects on the environment could be minimized. methods: to conduct this review article, all the scientific data related to the topic were gathered from scient...

This study deals with the selection of cutting process using grey fuzzy relation approach. The analysis was performed plasma arc machining, laser beam and abrasive waterjet machining on three different workpiece thicknesses speeds. objective to select best considering several performance characteristics such as time, dimensional accuracy, kerf width, surface roughness. Data normalization, coeff...

D.C. plasma torches are more and more widely used for different applications among which cutting, welding and spraying are probably the most developed. For a long period it is mainly their static characteristics which have been considered and their applications were studied on a macroscopic scale. However many transient phenomena occur, the systematic study of which has started only a few years...
