When designing an abrasive tool, it is necessary to know the most important properties of grain-bond system. The greatest interest study physical and mechanical characteristics tool: hardness, density, bending strength, modulus elasticity, Poisson's ratio, coefficient thermal expansion, properties, etc. There are extensive experimental data on testing tools in which a number empirical formulas ...

When an abrasive mixed with a polymer of special rheological properties and forced through a restricting medium, the abrasive and polymer will act as a self forming tool that precisely removes work piece material and improve the surface finish at those areas restricting to the medium flow. It is capable of machining areas which are difficult to reach by conventional machining and can be used to...

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...

A vision shAred by mAny experts is thAt future communities (residential and commercial developments, university and industrial campuses, military installations, and so on) will be self-sufficient with respect to energy production and will adopt microgrids. With power generation capacities of 10–50 mW, microgrids are usually intended for the local production of power with islanding capabilities ...

The aim of this work is to analyze the micro mechanisms underlying the wear of macroscale tools during diamond machining of SiCp/Al6063 composites and to develop the mechanism-based diamond wear model in relation to the dominant wear behaviors. During drilling, high volume fraction SiCp/Al6063 composites containing Cu, the dominant wear mechanisms of diamond tool involve thermodynamically activ...

In this article, the effect of parameters like working gap, work piece rotational speed and material removal mechanism(injection of the SiC Abrasive slurry and Al2O3, use of diamond paste as abrasive tool) in Magnetic Abrasive Finishing process using designing of experiments on the external surface of Cylindrical work pieces of Stainless steel AISI 440C to get minimum surf...

Abstract—Ultrasonic machining is one of the most widely used non-traditional machining processes for machining of materials that are relatively brittle, hard, and fragile such as advanced ceramics, refractories, crystals, quartz etc. Present article has been targeted at investigating the impact of different experimental conditions (power rating, cobalt content, tool material, thickness of work ...
