Effect of Machining Variables on Cutting Temperature While Rotary Milling of Inconel 625

Abstract

In the metal cutting process, the cutting temperature is a serious problem in the aerospace industry while machining of aerospace materials like nickel-based superalloys, titanium alloys, and structural composites. The cutting temperature plays an important role in metal cutting processes. The cutting temperature influences the tool life and surface roughness. Many researchers are focusing on the reduction of the cutting temperature. There are more techniques available to reduce the cutting temperature like flood coolant, minimum quantity lubrication (MQL) and nanocoolants. In this work, the cutting temperature was reduced by a new technique that is the self-propelled rotary tool (SPRT) with MQL and nanocoolants. The cutting temperature was measured using the infrared thermometer. The effect of cutting parameters on the cutting temperature was studied. The effect of the inclination angle in rotary milling was also analyzed. The results were obtained while machining of Inconel 625, a nickel-based superalloy using a self-propelled rotary face milling tool.
