Abstract
Micro-drilling is one of the advanced levels of metal cutting processes in the manufacturing and assembly industry, thereby producing micro-holes with higher depth, greater surface finish and better-quality of roundness. In this research work, micro-drilling has been done on Incoloy 800 which is an iron-based superalloy which has good resistance to corrosion, oxidation at higher temperature and is used in various equipments like superheaters, pressure vessels, heat exchangers, etc. The temperature and material removal rate (MRR) are analysed by varying the processes parameters like diameter of the tool, spindle speed and feed as per Taguchi L27 orthogonal array design. From this experiment, it is found that MRR and temperature increase with the increase in feed and speed of spindle. The results obtained by the experiments are optimized by using grey relational analysis (GRA).
