Effect of Amalgamation of Al2O3 and Mustard Oil Nanofluids in the Machining of EN8

Abstract

Modern machining industries are facing a challenge to attain of high worth in terms of work piece, surface finish, high production rate, tool wear, chip formation, the economy in machining based on cutting fluids and type of work material. It is crucial to establish most favourable cutting fluids to attain in elevation superiority products under machining under various cutting parameters like spindle speed, feed rate, depth of cut, type of cutting fluids, chip morphology, tool–chip interface which depends on cutting parameters and cutting fluids. Some problems are occurring during usage of various fluids in machining such as pollution, sound, health, manufacturing and maintenance price which are to be considerable and essential to overcome problems obtaining during machining and for these reasons need to develop hybrid fluids. Within this experimental study, an attempt has been made to examine the machining distinctiveness on EN8 steel using amalgamation of Al2O3 and mustard oil nanocoolants. EN8 material is commonly used in the automobile applications. In this study examining the influence of cutting fluids, the cutting parameters on chip formation develop during machining, cutting tool temperature, work piece temperature, tool wear and surface roughness during the machining of EN8 material. Within the present work, initially amalgamation of Al2O3 and mustard oil nanofluids has been prepared through magnetic stirring process with varying weight percentages, i.e. 1, 2, 3, 4% of Al2O3, and the prepared fluids have been tested for their fluid and thermal properties. The machining operations were performed using conventional lathe machine and cutting operations done by using HSS cutting tool and operating conditions taken as spindle speed (n) of 190 rpm, feed rate (f) of 0.4 rev/min and 0.6 rev/min and cutting depth taken from 1 to 2 mm. The obtained results conclude that there is a reduction of 15% in tool tip and 19% in work piece temperatures for fluid composition of 1% Al2O3 and mustard oil amalgamation compared to pure mustard oil, and also there is a reduction in tool wear rate with 16% and enhancement in surface roughness with 16% for fluid composition of 2% Al2O3 and mustard oil amalgamation compared to pure mustard oil.
