Objectives: To compare the process parameters such as tool performance, surface roughness in turning process under, dry and near-dry conditions. Methods\Statistical Analysis: This study deals with the comparative performance of carbide coated tools in conventional dry turning with minimal lubricant application method by varying depth of cut keeping feed and speed as constant. The performance of the tool and the roughness of the work material under different conditions are analyzed. Findings: It is found that according to the selected cutting conditions in the model-based comparisons, the predicted tool wear under near dry lubrication are reduced as high as about 30% compared with those in dry cutting while the predicted tool wear land lengths are reduced by 60% compared with those in dry cutting. After the physical behaviors in near dry turning are understood, it is possible to calculate the tool life with given material properties and cutting conditions. Applications\ Improvements: This study gives sufficient information about performance of carbide tool with minimum amount of lubrication.
