Effect of lubricant on turning characteristics of duplex stainless steel

The way cutting liquids are applied during cutting processes affects the physical phenomena that take place during cutting as well as the characteristics of the produced surface, tool wear and dimensional accuracy. Their use, however, results in a number of ecological and social issues related to environmental pollution and worker health is improved by 10%. For their eradication or a large decrease of 3%, a similar machined surface quality under dry cutting circumstances or with little to no lubrication is needed. The present research compares the topographical surface qualities that were acquired after a conventional supply of emulsion to those that were obtained following dry and minimal quantity lubrication (MQL) turning of steel. The majority of earlier research on the impact of the cutting environment on the quality of the machined surface was done in dry or wet environments. Other significant surface features were ignored in favour of analysing the surface texture using the surface roughness parameter Ra. According to the experimental findings, the cutting zone's environment and parameters had a significant impact upto 7% on the profile bearing ratio, surface roughness and cutting force occurrence of surface defects.
