Machinability of Nickel Chromium Case Hardened Steel (EN36C)
Nickel Chromium Case Hardened Steel (EN36C) is surface hardened low carbon steel provided with a strong core prepared by the thermo-mechanical process. Owing to high strength, corrosion resistance, shock resistance, and good fracture toughness properties this kind of steel is used. Heavy duty crane shafts, airplane gears, cam, rollers, truck construction, some structural members and other more are the applications of this steel. It is compatible with dynamic conditions where the load is fluctuating with time, but the rigorous amount of temperature develops due to friction. The paper presents the experimental study on machinability of the EN36C steel. Experimentation was carried out by Chemical vapor deposition (CVD) coated carbide tool. Speed, feed and depth of cuts are the input parameters and chip reduction coefficient, material removal rate (MRR) and Von Mises stress are the output responses. The input parameters were assigned with code and arranged in 33 factorial design forms according to the Design of Experiment (DOE).
