Abstract

This paper deals with the measurement of cutting force components generated in turning for different cutting parameters and different tools having various rake angles while machining EN 8 steel. The rake angles of the tool were changed using selected cutting parameters; thus, the cutting force components were measured. The selected cutting variables and the tools in different rake angles were tested practically under workshop conditions. During the tests, the depth of cut and cutting speed were kept constant and each test was conducted with a sharp tool. Finally, the effects of cutting parameters and rake angles on cutting forces were analyzed. A cylindrical EN8 work piece was turned using Carbide tools for 3 different rake angles (0°, 5° and 10°). A total of 9 experiments were carried out with three feed rates (0.065. 0.13 and 0.26 mm/rev) for each rake angle, keeping the cutting speed (384 rpm.) and depth of cut (1 mm) constant. During the experimentation, the forces were measured using a dynamometer. The experimental results show that the thrust force (Ft) is greater than the feed force (Ff) irrespective of the tool rake angle. The cutting forces were found to decrease with the increase in positive rake angle.
