Effect of knife velocity on cutting energy and efficiency during impact cutting of sorghum stalk



Effect of knife velocity on cutting energy and efficiency during impact cutting of sorghum stalk



Agricultural Engineering International 7: Manuscript PM 05 004



A laboratory test-rig consisting of a pendulum-like oscillating arm was designed and fabricated for measuring cutting energy requirement and cutting efficiency on sorghum stalk. The sorghum stalk was fixed in a stalk holder to simulate a free-standing stalk in the field. A blade, sharpened at 30% bevel angle, was attached to the lower end of the arm which cut the stalk at 90 degrees to the stalk axis with knife velocities up to 8.5 m/s.
