Abstract

Machining is one of the widely used methods in today's technology and there are many parameters that affect the machinability of the produced product. In the machining process, the machinability of the product depends on parameters such as feed rate, depth of cut, cutting speed and cutting fluid. The use of cutting fluid during the process has advantages such as improving surface quality, but also disadvantages such as increased cost and environmental damage. Due to these disadvantages of cutting fluid in manufacturing processes, alternative methods have been developed. The method called minimum quantity lubrication (MQL) not only reduces cost but also improves machinability. In this study, the machinability of titanium turning was evaluated with main cutting force, surface roughness and temperature measured in the primary cutting zone data. MQL method was used in the study and Taguchi L9 model was applied. The results were compared between dry cutting and MQL atmospheres. The reliability of the data and the degree of influence of the parameters were analyzed by ANOVA. In this study, the shear force data obtained in the dry shear atmosphere were higher than the data obtained in the MQL method. In addition, the surface roughness values obtained in dry cutting atmosphere were also relatively high. The optimum cutting speed, feed rate and depth of cut values for the process were determined as 60 m/min, 0.05 mm/rev and 0.5 mm, respectively.
