Wire saw, with its ability to cut very thin wafers from large diameter crystalline ingots of semiconductor materials, has emerged as a leading technology for wafer production in semiconductor and photovoltaic industry. Nevertheless, the wire saw cutting process remains lacking a theoretical methodology and is not properly understood. The modern times compulsion of more accurate and efficient ma...

The chip thickness is often used to characterize abrasive processes, particularly grinding. Unfortunately, because of the seemingly random nature geometrically undefined cutting points and difficulty in estimating cutting-point density, notoriously difficult quantify. Recently, dimensionless Aggressiveness number has gained popularity it circumvents need quantify wheel topography applicable any...

Mexico is the largest cactus exporter of the world and 40% of the production cost is provided from the harvest operation. Many workers are required to operate daily and suffer wrist pain after two weeks of collecting pears with mechanical pruners. A motor driven tool supplied from a photovoltaic system was employed for harvesting; different blades were tested at different cutting speeds. It was...

Abstrad-lo simulate general particle motion on the cross-section of a particle laden jetllow by using fractal point sets, a feedback control process is developed to ensurc the validity of nonlinear mapping techniques that transform an original fractal point set into the point set with any desired velocity profile. The points are utrlized to represent quantitatively functional ahrasive particles...

Abrasive Water Jet (AWJ); which may be accepted as a relatively new and nature-friendly technology for the industry, can simply be defined as the technological process that uses a transformation of the high-pressure jet to the high-speed waterjet as a tool for cutting substance, specially materials. As this technology has the ability of cutting some multicomponent materials in all directions, w...

This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...
