One of the newly developed methods for obtaining super finished surfaces for freeform is Magnetorheological finishing (MRF). MRF is an advanced finishing process in which the grinding force is controlled by magnetic field. The material removal in MRF is governed by the magnetorheological fluid which mainly consists of carbonyl iron (CI), abrasives particles, carrier fluids and additives. MRF pr...

A crucial and costly step in the whole manufacturing process is precision super finishing procedure. of final involved production components. It accounts for a respectable portion cost overall, mostly uncontrolled, requires lot manpower. Abrasive finish methods are being developed to address issues including high direct costs components with particular characteristics inaccessible places. vast ...

For complex curved difficult-to-machine parts, a new method based on pneumatic suspension abrasive pool bright finishing processing is proposed, using the mixing of abrasive, workpiece surface, and fluidized to produce relative motion velocity, so that solid particles surface microscopic two-body wear achieve effect precision machining. The experimental test material widely used Q235 steel plat...

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 order to expand the possibilities of designing technological processes for finishing shut-off valve parts, in some cases it is advisable use varying various influences a single combined method with imposition an electromagnetic field. A reasonable combination physical allows us provide necessary design parameters, sufficient productivity and increase resource finished products.

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...
