Investigate the effectt of approaching angle on cutting force during EN 8 steel turning
Main Article Content
Abstract
This paper deals ith the measurement of cutting force generated in turning for different cutting parameters and diferrent tools having various approaching angles while machining EN 8 steel. The approaching angles of the cutting tool were changed using selected parameters; and cutting force components were measured. The selected cutting variables and tools with diferrent approaching angles were tested practically under workshop conditions. During the experimentation, cutting speed and depth of cut were kept constant and each experiment was conducted with new sharp tools. Finally, the effects of cutting parameters and approaching angles on cutting force were analyzed. A cylindrical EN 8 workpiece was turned using carbide tools for three diferrent approaching angles (60̊, 75̊ and 90̊). A total 9 experiments were carried out with three feed rates (0.065, 0.13 and 0.26 mm/rev) for each approaching angle, keeping the cutting speed (384 rpm) and depth of cut (1 mm) constant. During the experimentation forces were measured using dynamometer. The experimental result show that the thrust force were decreased by increasing approaching angles and feed force were increased by increasing approaching angles.
