Investigations and Modeling on Advancement in Magnetorheological Fluid Based Honing Process

Abstract

The internal surface finishing of cylindrical components at nano-meter level with good surface characteristics is highly demanded in today s industries for improving their operative functionalities. There are various cylindrical components which require internal surface finishing at a high precision level with good surface integrity. These cylindrical components are used for cylindrical molds and dies, hydraulic cylinders, cylindrical barrels for injection molding, air bearings and cylindrical tubes for the flow of high purity liquids etc. The highly finished internal surface of cylindrical components also results in resistance to wear, corrosion, pitting and oxidation. In industries, mostly traditional finishing processes like grinding or honing are used to finish the internal surface of the various cylindrical components because of their easy accessibility and low making cost. These traditional finishing processes make use of rigid tools and when the rigid tools perform surface finishing, they do not have control over the finishing forces. Owing to this, sometimes the defects get produced like pit holes, sharp edges, torn and folded metals etc. on the final finished surface. Moreover, the traditional finishing processes can finish the surface up to a certain level because of the use of the rigid abrasive tools and further to achieve a very fine level of surface finishing may not be possible. Therefore, there is a mandatory requirement of the advanced finishing processes to finish the internal surface of the cylindrical components for enhancing their operational life in real applications.
