 in terms of the surface quality of the machined workpiece, tool wear and the temperature at the cutting zone. The research was conducted varying the angle of feeding from 30° to 180°, while the depth of cut and the feed rate were kept at constant values of 1.5 mm and 0.75mm/rev respectively. The speeds used were 63, 125 and 180 rpm respectively. The poorest performance of the cutting fluid (CF) was achieved when the speed was 125 rpm particularly in terms of the tool life and temperature, while the best performance of the CF was obtained under the speed value of 180 rpm particularly as regard the surface quality. The best surface quality (i.e. the lowest surface roughness) was 5.77µm when the angle of feeding was 150° followed 6.79µm at feeding angle of 60°. This certifies the fact that the angle of feeding affects the performance of the CF. The lowest tool wear value (the highest tool life) was established under the speed of 63 rpm corresponding to 0,04mm, while the lowest temperature was 24.54°C which was obtained at the speed of 180 rpm. The optimum speed recommended therefore, was 180 rpm.&picture=http://www.aascit.org/aascit/decorators/img/journal/896.jpg)

The cutting speed is one the most important parameters of machining processes. It influences the tool life by influencing the tool wear rate, the surface quality of machined workpiece by influencing the surface roughness of the workpiece. The speed also affects the temperature at the cutting zone. Therefore, this research investigated the influence of speed on the effectiveness of the two-way application of cutting fluids (CF) in terms of the surface quality of the machined workpiece, tool wear and the temperature at the cutting zone. The research was conducted varying the angle of feeding from 30° to 180°, while the depth of cut and the feed rate were kept at constant values of 1.5 mm and 0.75mm/rev respectively. The speeds used were 63, 125 and 180 rpm respectively. The poorest performance of the cutting fluid (CF) was achieved when the speed was 125 rpm particularly in terms of the tool life and temperature, while the best performance of the CF was obtained under the speed value of 180 rpm particularly as regard the surface quality. The best surface quality (i.e. the lowest surface roughness) was 5.77µm when the angle of feeding was 150° followed 6.79µm at feeding angle of 60°. This certifies the fact that the angle of feeding affects the performance of the CF. The lowest tool wear value (the highest tool life) was established under the speed of 63 rpm corresponding to 0,04mm, while the lowest temperature was 24.54°C which was obtained at the speed of 180 rpm. The optimum speed recommended therefore, was 180 rpm.
