Diamond turning of steel alloys is impractical due to catastrophic tool wear caused by a combination of chemical and abrasive wear. In the literature, several modifications of the cutting process have been proposed, e.g. cutting in an inert gas atmosphere, cryogenic cutting and vibration assisted cutting, e.g. elliptical vibration cutting (EVC) [1-5]. In this work, the EVC method was investigat...

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 ...

A theoretical framework is established for constructing arbitrary particle-laden jetflow by means of fractal sets in the sense of average scale. This novel approach involves three main coherent components, in which one (1) searches for an appropriate original point set and confirms its intrinsic properties such as chaos, symmetry and density distribution; (2) derives governing equations for the...

Abrasive water jet machining (AWJM) is a relatively new machining technique. Abrasive Water Jet Machining is extensively used in many industrial applications. AWJM is a nonconventional machining process where material is removed by impact erosion of high pressure high velocity of water and entrained high velocity of grit abrasives on a work piece. There are so many process parameter affect qual...

A general model is pre~nted for the simulation of a drilling process by abrasive waterjet. The conventional constitutive equation for the erosion rate of a single particle penetrating into a solid target is extended and applied to millions of particle strikes, taking into consideration their erosion histories. The theoretical advancement of this model reflects the inherent damping effect that o...
