ABSTRACT
Due to the aesthetic appearance and applicability of the freeform surface, its manufacturing aspects are being explored by several industries especially working in the area of bio-implants. Due to their functional requirements, some products with freeform surfaces also need very high surface finish quality. However, due to the limitations of conventional finishing operations, super finishing of freeform and other complex surfaces is still considered challenging. Therefore, in the last 20 years, many super finishing processes have been developed to satisfy this requirement of finishing freeform and other non-planar surfaces. Several variants of magnetic field-based finishing processes have been evolved for different types of surfaces in this domain. A magnetic field assisted finishing (MFAF) process is a well-established technique that can finish various kinds of surfaces up to nanolevel surface roughness. In this chapter, some variants of the MFAF process (used for different types of 3D surfaces) have been discussed. Each of the discussed processes is based on MFAF and is used for a specific variety of 3D surfaces. In addition, experimental findings related to these processes have also been discussed to explain the process mechanism.
