Abstract |
The need of present industrial industries are 3-D component of complex shapes possessing extraordinary properties nano-Ievel surface finish and having miniature features because of development of new materials which are difficult to machine no traditional methods fulfill such demand. Precision finishing and machining complex geometry is difficult to control, labour intensive and hence always a big concern, If traditional methods may use to achieve same needs it require large labour and expensive equipments which make the process economically unimportant. There are no traditional methods which meet such industrial demand, so to develop the some advanced manufacturing processes is of utmost importance of present manufacturing scenario. Some of advanced manufacturing processes like AJM, EDM. USM, LBM. And ECM are widely used to Machine such hard materials. Many new methods have been developed for obtaining super finished surfaces one of them is Magnetorheological Fluid Finishing (MRFF), In MRFF, the magnetic field controls the grinding force. The magnetic rheological fluid (MR fluid) governs the material removal and it is composed of mainly Carbonyl Iron particles (CIP). Carrier fluids, abrasives. Nano metric- scale finishing can be achieved by using this process. MR fluid acts as a flexible tool in the MRFF process to provide the finishing action. Here a setup for MRFF application has been developed using the pillar drilling machine available in the workshop. Using design of experiments technique. Experiments have been planned to be conducted and obtain the data required for statistical analysis in Minitab software. The present study shows that the maximum percentage of surface improvement is obtained in flat-Cu work piece. The parameters which play a major role in improvement of surface roughness are rotational speed. Magnetic poles arrangement, duration of experiment and MR fluid composition. The surface roughness improvement also depends on hardness and geometry of the work piece. In the present work experimental results are compared with experimental result and it is found that both come in micron range. |
