The Analysis of Process Parameters for Turning Cobalt-Based Super Alloy Haynes 25 / L 605 Using Design of Experiment

Abstract:

Haynes-25 alloy (also known as L-605 alloy) is extensively used in the applications of aerospace industry, turbine and furnace parts, power generators and heat exchangers and petroleum refining components due to its excellent properties. However, machining this alloy is more difficult compared to normal steel or even stainless one because of its characteristics of hardness and strength. This paper presents experimental investigation into machining parameters in the turning process of Haynes 25 alloy using uncoated carbide tools. Design of experiment (DOE) has been used for studying the effect of the main turning parameters such as cooling condition, cutting speed and feed rate on the arithmetic average surface roughness (Ra) of Haynes-25 alloy. Tests are designed according to Taguchi’s orthogonal array. Experiments have been performed under dry cutting and conventional wet cooling. Minimum surface roughness was obtained in turning using uncoated tools under wet cooling condition at the cutting speed of 45 m/min and feed rate of 0.12 mm/rev.
