Abstract
nIn machining of Titanium alloys, the cutting temperature plays a vital role that directly influences the performance and it is required to maintain as low as possible. In this study, a dual nozzle Vortex Tube Cooling System (VTCS) that supplies cool compressed CO2 gas is developed to reduce the cutting temperature in Ti-6Al-4V machining. The experiments were conducted at constant cutting and flow parameters during turning at different levels of nozzle angle, nozzle position from the cutting edge (tool tip distance) and at particular diameter of the nozzle. From the results, cutting force was found to improve with a greater nozzle angle and decrease with a greater nozzle tip, due to strain hardening effect on the Ti-6Al-4V and the high-pressure CO2 gas jet on the cutting tool. Cutting temperature reduced at higher nozzle angle, however it is first decreased and then increased with tip nozzle distance because of high heat transfer coefficient of cold compressed CO2 gas, and more heat removal from the machining zone. Surface roughness increased with the nozzle angle, it is first decreased and then increased with tip nozzle distance due to reduced coefficient of friction that CO2 gas provides at interfaces. The results demonstrate the effectiveness of the dual nozzle VTCS in improving machinability and surface quality for polymer and composite materials through efficient cooling and lubrication.
