| Abstract: | In this study, improvement of near-dry machining (NDM) and its effect on tool wear in turning of AISI 4142 by carbide tool (DNMG 150608-PM) is investigated. First, the preparation of experimental setup was carried out, and then, some experiments to study the process were performed. Surface roughness was used as the criterion of finding the optimal conditions of fluid flow rate and frequency, and position and angle of nozzle. After optimization of the process, some experiments were performed to study tool life. Machining force, roughness, and tool wear were chosen as the criteria to determine the tool life. Obtained results show that the tool life in NDM is longer than that in dry machining. |
