In this study, micro fluid channels are machined on fused silica glass via powder blasting, a mechanical etching process, and the machining characteristics of the channels are experimentally evaluated. In the process, material removal is performed by the collision of micro abrasives injected by highly compressed air on to the target surface. This approach can be characterized as an integration ...

One of the common issues that arises in abrasive machining is the inconsistency of the surface roughness within the same batch and under identical machining conditions. Recent advances in engineered abrasives have allowed replacement of the random arrangement of minerals on conventional belts with precisely shaped structures uniformly cast directly onto a backing material. This allows for abras...

Finishing methods of machining superhard composite’s working elements based on cubic boron nitride BL group are considered. The results the microgeometry formation research cutting inserts’ surfaces during by free powders synthetic diamond, grinding wheels and a method vibro-magnetic-abrasive (VMAM) presented. It is shown that VMAM friction between abrasive particles result in microremoval mate...

Adhesion strength of exterior or interior coating of steel pipes is too important. Increasing of coating adhesion on surfaces can increase the life time of coating, safety factor of transmitting line pipe and decreasing the rate of corrosion and costs. Preparation of steel pipe surfaces before doing the coating process is done by shot and grit blasting. This is a mechanical way to do it. Some e...

In this work, the Prediction of acceleration amplitude and surface roughness of Aluminium alloy (Al6061), reinforced with 15% Silicon Carbide particle (SiCp) metal matrix composites, has been made in the end milling process considering various machining parameters. The MMC was considered the difficult to machining due its reinforcement hardness and nature of abrasive element and the prediction ...

Abrasive flow machining is one of the promising technologies for finishing rectangular channels, which are characterized by a constant increase in accuracy and reduction surface roughness. During modeling contact interaction grains corners part cross-section intended abrasive machining, key features size filler grain selection were fixed. In proposed spherical model, cutting edge represented an...

Abrasive air jet (AAJ) machining is attractive for micromachining hard and brittle materials, while it usually a big challenge to numerically investigate the particle velocity concentration distribution in erosion process AAJ. In this work, recently developed semi-resolved CFD-DEM approach which bridges simulation gap between resolved unresolved CFD-DEM, further improved reconstruct background ...

From last two decades, plant fiber reinforced polymer/polyester composites have been effectively used in structural and automotive applications. Researchers manufacturers are looking forward for an effective utilization of these composites. However, despite the outstanding properties terms load bearing capacity environmental sustainability fibers uptake limited due to its poor machinability cha...
