Effect of Vibration on Surface Texture during Machining Multiphase Microalloyed Steel

Multiphase ferrite-bainite-martensite (FBM) microalloyed steel produced through two step cooling procedure was turned and compared with ferrite-pearlite (FP) microstructure and tempered-martensite (TM) microstructure to study the effect of vibration on surface finish. The cutting parameters like cutting speed, feed and depth of cut were varied to understand the parameter influence on surface finish due to vibration. The result shows that FBM microstructure steel gives better performance in terms of lower surface roughness and lower vibration compared to FP and TM microstructure steel.
