Controlled depth abrasive waterjet machining (AWJM) is an unconventional and promising process for materials introducing challenges in conventional high value manufacturing (HVM) industries such as aerospace automotive. In applications, acts a flexible cutting tool compared to milling. The kerf profile, i.e. the removed material volume, nonlinearly depends on parameters water pressure, jet trav...

Aluminium metal matrix composites (AMMCs) are now gaining their usage in aerospace and automotive industries. Because of their inherent nature, difficult to machine, they find very little applications in other sectors. Even non traditional processes like Laser Jet Machining and Electro Discharge Machining result in significant sub surface damage to the work. In this paper, an attempt is made to...

Sampling of the full range of particle sizes was carried out on 16 processes in six different General Motors plants over a period of 2.5 years. This article deals with particle characterization from five of the processes that relate to machining, specifically, wet machining with water-based fluids from old and new technology processes, grinding with straight oils from old and new technology pro...

Dry areas near the sea can obtain fresh water through solar distillation of saline sea water resources. However, these solar distillation sites produce wastewater as a result of desalination of sea water with high salt concentration. Waste must be disposed of with the least effect on the receiving environment (sea, in most cases). Initial dilution and its characteristics play important roles in...

As a new manufacturing process, abrasive water jet (AWJ)cutting has been very effective for difficult-to-machine materials. From the point of view of jet generation, abrasive water jets can be categorized as injection jeti or suspension jets. Injection jets are the most commonly used type for practical applications. An injection AWJ is formed by accelerating small abrasive particles through con...

Being subjected to a high-pressure abrasive water jet, solid samples will experience an essential variation of both internal stress and physical characteristics, which is closely associated with the kinetic energy attached to the abrasive particles involved in the jet stream. Here, experiments were performed, with particular emphasis being placed on the kinetic energy attenuation and turbulent ...
