Advanced Fine Finishing Process

ABSTRACT

This technology is so helpful in our everyday life. This paper dealt extensively about the latest technology which is useful for finishing materials with a very high precision. These latest processes are known as Advanced Fine Finishing Processes. In this paper, we gave a thorough

insight into some of these processes.

With the demand of stringent technological and functional requirements of the parts from micro- to nano-meter range, evolution of ultra-precision finishing processes became obvious need of the manufacturing scientists and engineers. The traditional finishing processes of this category have various limitations, for example complex shapes, miniature sizes, and 3-D parts cannot be processed & finished economically and rapidly. This led to the development of advanced finishing techniques like Abrasive Flow Machining, Magnetic Abrasive Finishing, Magnetic Float Polishing, Magneto-rheological, Abrasive Finishing, and Ion Beam Machining. In all these processes except Ion Beam Machining, abrasion of the work piece takes place in a controlled fashion such that the depth of penetration in the work piece is a fraction of micrometer so that the final finish approaches towards the nano range.

The working principles and the applications of these processes are discussed in this paper along with some recent research going on in these areas.
