Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...

Abrasive machining is one of the most non-conventional processes for finishing. It is widely used in industry to machine the materials like mild steel, aluminum, copper, titanium, glass, hard rock material, graphite, composite material, ceramics etc.Like in abrasive jet machining. This technique uses jet which contains abrasive material. Now a day water-magnetic abrasive machining is one of the...

the vibratory finishing is one of the important mass finishing processes. this can be applied for finishing many metallic and non- metallic components using abrasive materials such as steel, ceramic, natural materials and etc. the vibratory finishing process is used for some purposes such as surfaces polishing, deburring, oxide layer removing and rounding the edges. evaluation of surface roughn...

In order to improve the finishing efficiency of Magnetic Abrasive Finishing process, we proposed a new MAF process with renewable abrasive particles using compound magnetic fluid circulatory system in this paper. This has circulating that uses conveyor belt renew mixed particles. not only maintains stability but also ensures processing does need be interrupted. study, investigated field distrib...

in magnetic abrasive finishing (maf), abrasive grains as a tool move on surface and can removechip from surface of work piece. in this study al 6061 tube was considered as the work piece andthe effect of finishing parameters such as gap distance between tube and poles, rotational speed oftube, abrasive ration and finishing time on surface roughness was investigated. the mixture offerromagnetic ...

Based on the characteristics of solid magnetic abrasive and abrasive flow finishing, a new technology of viscoelastic magnetic abrasive finishing is presented. The theoretical micro model of viscoelastic magnetic abrasive tools is established, and influencing factors of a positive pressure are determined by force analysis. Finishing mechanism of micro-grinding, slipping, rolling and so on is an...

In chemical mechanical polishing (CMP), a rigid wafer is forced on a rough elastomeric polishing pad, while a slurry containing abrasive particles flows through the interface. One of the important factors that influence the material removal rate in CMP is the magnitude of contact force transmitted to the abrasive particles trapped at the contact interface. The total push-down force is distribut...

Surface finishing is one of the most significant steps in industries which are engaged with surface quality. Finishing by magnetic field is a new method of surface finishing. In this process, machining is executed in mechanical way and semi-homogeneous abrasive slurry performs finishing of surfaces. Needed force to grind surfaces is made by magnetic field. Therefor this method is considered as ...

Applied pressure in chemical mechanical polishing CMP is shared by the two-body pad–wafer and the three-body pad–abrasive– wafer contacts. The fraction of applied pressure transferred through the particle contacts is a significant factor as most of the material removal is due to abrasive particles trapped in the pad–wafer interface. In this work, the contact of a rough, deformable pad and a smo...
