Abrasive machining is a machining process where material is removed from a workpiece using a multitude of small abrasive particles. Common examples include grinding, honing, and polishing. Abrasive processes are usually expensive, but capable of tighter tolerances and better surface finish than other machining processes
Abrasive flow machining is a non-conventional machining process and was developed in late 1960's as a method to deburr, polish and radius difficult to reach surfaces such as intricate geometries ...

ماشین کاری با جریان ساینده، یک فرایند پرداخت کاری است که در آن حرکت یک خمیر نیمه جامد از ذرات ساینده بر روی سطحی که قرار است پرداخت شود باعث برداشت مقدار کمی ماده می‌شود.
پرداخت‌کاری با ساینده مغناطیسی (به انگلیسی: Magnetic Abrasive Finishing) یک روش پرداخت سطح است که از یک میدان مغناطیسی برای وارد کردن نیرو به ذرات ساینده جهت برخورد ذرات به سطح مورد نظر استفاده می‌کند.
Abstract. Micro-/nano-machining (abbreviated as MNM) processes are classified mainly in two classes: traditional and advanced. Majority of the traditional MNM processes are embedded abrasive or fixed geometry cutting tool type processes. Conversely, majority of the advanced MNM processes are loose flowing abrasive based processes in which abrasive orientation and its geometry at the time of ...

There is disclosed a method of monitoring abrasion of a component during abrasive machining. The method comprises generating an acceleration signal corresponding to movement of the component or of an abrasive tool in response to abrasive machining of the component by the tool; generating an acoustic emission signal corresponding to acoustic waves emitted from within the component; and ...
The process is abrasive only where the flow is restricted: the extrusion area. The machining action compares to a grinding or lapping operation as the abrasive media gently and uniformly hones the surface or edges. Materials from soft aluminum to tough nickel alloys, ceramics and carbides can be successfully micro-machined with this process.
Development of magneto abrasive flow machining process. Abrasive flow machining (AFM) is a relatively new process among non-conventional machining processes. Low material removal rate happens to be one serious limitation of almost all such processes. Limited efforts have hitherto been directed towards improving the efficiency of these processes ...

Abrasive flow machining (AFM) is a non-traditional finishing process, which possesses excellent capabilities for finishing complicated surface and inaccessible regions of a workpiece [1]. In AFM, an abrasive-laden polymeric medium is extruded under pressure through the surface to be machined or the restrictive passage formed by the workpiece ...
Abrasive flow machining is a finishing process in which a small quantity of material is removed by flowing semi-solid, abrasive-laden putty (called media) over the machined surface. The media is a rubber-like material of a high viscosity and can be deformed by applying a little pressure.

Modern manufacturing processes like abrasive flow machining (AFM) are often employed for finishing the conventionally inaccessible surfaces that include the inner surfaces of cylindrical workpieces. This process is used for accurate prediction of the generated surfaces. As such, regression models are useful for such a prediction. In the existing AFM setup, the nylon fixture is …

Abrasive-jet machining has become a helpful tool in medical and electronics manufacture, where it is used for drilling, deburring, beveling, lead cleaning, wire stripping, and coating removal. Unfortunately, the process tends to generate electrostatic charges within work chambers. In fact, abrading.
Embedding of abrasive particles can be an unwanted consequence of micro-abrasive air-jet machining (MAJM) of polydimethylsiloxane (PMDS). In this work, the extent to which the abrasive is embedded is analyzed quantitatively by a modeling analysis involving the impact velocity, impact force, and erosion depth of the single abrasive particle on PDMS combined with the change in the material ...
