Abstract

Because of its unique qualities, Nimonic C-263 Alloy is widely utilised in aircraft, gas turbine blades, power generators, and heat exchangers, among other applications. The materials are finding new uses in the fabrication of essential components for high-performance aviation gas turbine engines, partly because of their outstanding mechanical qualities that stay stable at high temperatures. According to a prior study, the most prevalent issue other researchers have run across while examining Nimonic C-263 Alloy is the cutting tool’s short life cycle and thermal degradation. Besides, the cutting tool's wear is the most common problem encountered throughout this procedure. This study aims to conduct an experimental investigation of the wear characteristics of tools when turning Nimonic C-263 Alloy. This research will focus on the experimental investigation and analysis of machining parameters while turning Nimonic C-263 Alloy with PVD coated inserts to predict their optimal values. Cutting speed, feed rate, and depth of cut were the parameters that were considered for the parameters. The indication of process performance, the cutting temperature, and tool wear will be monitored and recorded. Using Response Surface Methodology (RSM), an empirical model will be developed for predicting tool wear and heat generation. From the results, the highest tool life documented in the research is 19.25 minutes, while the least is 1.97 minutes. By comparing the experimental result with the theoretical value with an error of less than 10 per cent demonstrates that the mathematical model accurately predicted the tool life.
