• An experimental investigation has been performed in turning of Ti-6Al-4V by using coated carbide tool employed under dry condition and pressurized coolant at the flank and rake surfaces concurrently. To impinge coolant in this manner, customized nozzle was designed and fabricated. As part of the study, the cutting force, feed force, cutting temperature, and chip characteristics were explored as quality indices at varied speed and feed. To do so, the cutting forces and temperature were measured by using a robust 3D dynamometer and tool-work thermocouple, respectively. Apart from experimental investigation, the role of each factor was quantified by the statistical analysis of variance; consequently, it was revealed that the high-pressure coolant exerted a significant impact on all the responses. Results showed that the effective cooling and lubrication were achieved by the coolant jets; this reduced the cutting forces and temperature. In addition, the shortened chip-tool contact length and jet activated wedge effect contributed to the improved machining performance. Nevertheless, the chip breakability was not favorable which can be attributed to the low pressure of the supplied coolant.
