Magnetic Abrasive Finishing Process

Abstract

The demand for high finish with accuracy combined with difficulty to finish components by conventional methods lead to the growth of advanced finishing processes. Magnetic abrasive finishing process is an advanced finishing process capable of finishing, deburring and precision chamfering of components. Magnetic abrasive finishing process can economically achieve nanometre surface finish on flat and cylindrical workpieces both internal and as well as externally. During magnetic abrasive finishing process, very low magnitude of finishing forces is applied on the magnetic abrasive particles to obtain nanometre surface finish. Therefore, it is particularly useful in finishing brittle materials without developing micro cracks and other defects. Various researchers modified the process and developed its hybrid variants. Their prime objective is to make the process more efficient and also capable of finishing micro features. To understand the physics of the process a considerable amount of work has been carried out in the form of experimental study with few attempts in the modeling of the magnetic abrasive finishing process.
