Effect on Magnetic Abrasive Machining with Different Range of Electrical Parameters

Magnetic abrasive machining is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible. The aim of this paper is to study maximum efficiency in terms of material removal rate with respect to magnetic flux density with respected to the different types of coils. Magnetic abrasive finishing is an efficient tool for internal finishing of bent tubes. In this research work SS 304, cast iron and brass cylindrical work piece was finished using a magnetic abrasive finishing process so as to study the effect of magnetic flux density on material removal rate with respect to various parameters so as to find the best parameters at a particular range of electromagnetic flux coil. A cylindrical workpieces was finished using a magnetic abrasive finishing process on an apparatus developed for carrying out testing work. The process principle and the finishing characteristics of magnetic abrasive finishing of cylindrical pipes using sintered magnetic abrasives are described in this paper. The sintered magnetic abrasive is a mixture of Al2O3 abrasive and ferromagnetic particles. Results showed maximum efficiency on a medium range of magnetic flux density.
