An Experimental Investigation On Machinability Of Waspaloy
Nickel-based Superalloys such as Waspaloy provide several advantages, including a high-temperature strength
and high corrosion resistance. Therefore the demand for such material has rapidly increased, particularly in aerospace
industries, steam turbines and gas turbines applications. On the other hand they are known as one of the most difficult to cut
materials due to their mechanical and chemical properties and the tool life is extremely short. In this paper the analyses of
surface roughness (Ra), tool tip temperature (Ti), cutting force along x-direction (Fx), cutting force along y-direction (Fy) and
cutting force along z-direction (Fz) in machining of waspaloy by considering the cutting parameters feed, speed and depth of
cut. The machining tests have been carried out using carbide insert under different condition using Taguchi’s orthogonal array.
The experimental results are investigated using analysis of variance (ANOVA).
