turning, surface roughness, cylindricity deviation, environmentally friendly machining


One of the defining global issues today is to reduce the load on the environment. Thus, in this paper, the effect, and consequences of the abandonment of cooling and lubrication were investigated when turning of non-alloyed steel. The 2D and 3D surface roughness parameters, cylindricity deviations and circularity errors were examined at different feeds and cutting speeds. The experiments were performed, using the full factorial experimental design method. It was found that with dry machining, the average roughness is slightly higher with increasing productivity, however, at lower feed and cutting speeds, the surface has better wear resistance and lubricant retention, and cylindricity deviation can be minimized.
