Studies in Surface Finishing of Inconel718 Flat Surface with Magnetic Abrasive Finishing
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 4
Abstract
With technological developments in manufacturing industry, very hard and tough materials are being developed. Inconel 718 is one such material, which is a nickel based super alloy having high temperature and high-pressure applications. Inconel 718 is very difficult for machining, because of its materialistic properties. Surface finish produced after any machining process on inconel718, is generally not up to the required level. So, surface finishing of Inconel718 is a challenging job to tackle with. In the present research work, an attempt has been made for external surface finishing, of Inconel 718 flat surface (5mm thickness plate), by using magnetic abrasive finishing process. Several experiments have been designed and performed, to study the effect of three selected process parameters such as processing time, pole rotational speed and weight percentage of abrasive particles, on percentage improvement in surface finishing. An experimental set up has been developed, to investigate the performance in term of percentage improvement in surface finish and qualitative micro structural changes on the surface, by using SEM. For the analysis of experimental results, an ANOVA has been used. Experimental results indicate that, all the above-mentioned parameters have significant effect on surface finishing of Inconel718.
