Superalloys are developed to withstand severe mechanical stresses and high temperature
operation, and are widely used in aircraft and space vehicles, especially nickel-based ones, due to their
high corrosion resistance. In this study, three different cutting forces and surface roughness qualities were
evaluated depending on the cutting speed in the machining of Rene 41 superalloy with three different
ceramic tools KYON 4300, KSY25 and KSY30. In this work, The experimental results have revealed
that the feed rate had a serious effect on the cutting forces, while the effect of turning speed and type of
the cutting tool on the cutting forces are relatively small. On the other hand, the most important factor
influencing the surface roughness was cutting speed followed by tool type and feed rate, respectively. The
presented findings can help for understanding the machinability and surface characteristics of Rene’41
during high speed turning. In the experiments, it was observed that the cutting forces decreased as the
cutting speed increased.
