The performance of a two-way cutting fluid application was investigated to examine how a change in the angle of cutting fluid (CF) feeding impacts it. The inspiration for this study stemmed from the fact that little or no research has been done on a two-way CF application, as well as the findings of our previous study. The studies were carried out on an XL400 centre lathe machine. The cutting tool was a rectangular cemented carbide tool insert, and the workpiece was medium carbon steel. The surface quality of the machined workpiece, the rate of tool wear, and the temperature of the cutting zone were all studied under various feeding angles. The experiments were carried out under the following machining conditions: Cut depth (t) =1.5 mm, rotational speed (V) = 180 rpm, and feed rate (f) = 0.75 mm/rev In terms of surface quality, the two-way cutting fluid application was most effective when the feeding angle was 150o. i.e. at this angle, the lowest surface roughness value was attained, which was 5.77 m compared to 9.67 m for one-way CF application. In other words, the roughness of the surface was reduced by 40.3 percent. The tool wear and temperature at the cutting zone for the two-way application were 0.11 mm and 25.60oc, respectively, compared to 0.15 mm and 30.48oc for the one-way application. At a feeding angle of 60o, the lowest tool wear (maximum tool life) and temperature were achieved. For the two-way application, the tool wear and temperature were 0.11 mm and 24.54oC, respectively, compared to 0.15 mm and 30.48oC for the one-way application. Self-excited vibrations of the machine tool may be to blame for some of the aberrant values obtained for the two-way application. At this angle, the surface roughness value was 6.79 m, which was the next lowest value in the entire experiment. As a result, the most effective angles for supplying CF to the cutting zone via two-way application were 60o and 150o, respectively. As a result of the findings, it can be concluded that the angle at which CF is fed to the cutting zone has a bigger impact on its effectiveness.
