Investigations on the Performance of Minimum Quantity Lubrication using Non-Edible Oils in the Turning of AISI 630 Steel Objective: Enhance the turning performance by reducing the cutting temperature and surface roughness at the machining zone using vegetable oil-based spray cooling. Brief discussion: The work has been carried out systematically in three phases to establish the objectives. The experiment was conducted to investigate the spray characteristics of nonedible oils using PDPA and studied the effect of MQL system parameters on spray characteristics. The experiments were performed to investigate the performance of the turning process under a dry environment, and the optimum machining parameter was determined for the machining responses. The experiments were performed to analyse the machining performance under the MQL environment, and the optimum MQL system parameter was determined for the machining responses. Besides, A self-fabricated MQL system was developed for supplying the cutting fluid in the form of mist, and a temperature measurement system was also developed for measuring the tool-work interface temperature.
