Globally, the methods by which the products are designed and manufactured are advancing at rapid pace. In the present scenario, the identity of the lubricants and the coolants are classified as the toxic fluids not only to operators but also degrade the environment. Industries and researchers are working for the new advancement to reduce or eliminate the use of cutting fluids, both for economic and ecological reasons. Minimum Quantity Lubrication (MQL), which minimizes the use of cutting fluid proved advantages comparative to Flood cooling reduces the quantity of the lubricant to much extent, had gained popularity as a new substitute for Flood Cooling. The use of MQL in machining not only results in increase tool life, controlled temperature at chip-tool interface but provides with a cleaner environment and much amount-effectual machining technology. This paper presents a parallel analysis into the effect of temperature, roughness and tool wear at different cutting speed during turning of C45 steel. Dry cutting and minimum quantity lubrication (MQL) results are also compared and conclusions are analyzed. The experimental outcome demonstrates that the cooling and lubricating conditions influence altogether the researched procedure and surface properties which depends to a substantial degree on the connected cutting parameters, in particular the cutting speed and feed rate.
