Magneto-elastic abrasive grains have magnetism, low elastic modulus and excellent performance, the characteristics of bonded loose grains. The dual-disk magnetic preparation greatly improves quality efficiency. Firstly, magneto-elastic particles are introduced into edge tool, method 4035 silica gel is proposed. According to microscopic particles, finite element software ABAQUS used establish pa...

This research proposes an optimized magnetic abrasive machining process that uses an ultra-high-speed system to perform precision machining on a workpiece. The system can process several microns of material, either for machining surface roughness or for machining a workpiece for a precise micro-diameter. The stainless steel workpieces have been machined using an ultra-high-speed magnetic abrasi...

Wear maps were developed following a series of micro-abrasion-corrosion testing during idealised hip contact conditions for a CoCrMo alloy in a foetal calf serum solution. The main aim of the study was to characterise wear-corrosion or bio-tribocorrosion regimes of the alloy over a range of applied loads and applied potentials. The transitioning micro-abrasion-corrosion mechanisms, synergisms a...

The increasing use of high-pressure water jets in the industry for machining materials yields numerous studies aiming at the optimization of this technology. Since the experimental study of pure or abrasive water jet cutting is complex to carry out, the numerical simulation of this process stands as an attractive alternative. Such a simulation relies on the coupling of numerical tools devoted o...

The process monitoring and mechanics of fixed abrasive diamond wire saw machining are investigated in this study. New techniques to affix diamond particles to a steel wire core have advanced to make this process feasible for the machining of ceramics, wood, and foam materials. Developments in fixed abrasive diamond wire machining are first reviewed. Advantages of using fixed abrasive diamond wi...

Fluid jet machining has been widely used in of hard-brittle materials. However, the diffusion a flow significantly affects erosion capacity. Magnetorheological (MR) fluid considered to take role pure water for carrying abrasive particles, due its better concentration when external magnetic field is applied. The present investigation focuses on characteristics magnetorheological jet, which are i...

In this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. This mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (MAF) process. A permanent magnet which is mounted on a horn has been used as the processing tool. This polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. Ultrasoni...
