Application of Taguchi-Response surface analysis to optimize the cutting parameters on turning of Inconel X-750 using Nanofluids suspended Al 2O 3 in coconut oil

摘要

Inconel X-750, a nickel-chromium alloy, is found as a component in applications of the airframe and hot-air duct system. This paper presents the effect of different nanofluids (NF) concentration along with cutting speed and federate on Fz: cutting force, Ra: surface roughness and Vba: tool wear with the application of vegetable oil NF on turning of Alloy 750. The NF and vegetable oil taken for present investigation are nAl2O3and coconut oil. Experimental is carried out using L9orthogonal array and turned with PVD (AlTiN) coated carbide inserts. From the experimental research, 1.00% nAl2O3nanofluids in coconut oil along with cutting speed of 87m/min and 0.14 mm/rev feed rate has proved the better machining performance to minimize the responses. Based on optical micrograph analysis, abrasion, adhesion and small BUE wear are three modes of wear mechanisms. Ribbon chips are produced with a different diameter, and curl diameter is increased with the increment of percentage concentration on turning of Inconel X-750.
