EXPERIMENTAL EVALUATION ON THE QUALITY OF MACHINED SURFACE AFTER TURNING OF MATERIAL INCONEL 625

Abstract

Study relates to machining of toughly-machined metal materials specifically turning of the Inconel 625. There had been planned an experiment to find out the impact of setting the individual parameters of machining(cutting speed, feed rate, depth of cut)onto the quality of machined surface. Such experiment was the type of ‘box behnken’and contained 15 rounds. Following was the evaluation of the machined surface quality and their topography thanks to 3D profilometer Taylor Hobson Talysurf CCI Lite, based on which there were created 3D colour filtered pictures of the surface of the samples. Morphology of the surfaces was investigated by electron microscopy.
