Next, the effects of varying knife oblique
angles from 0° to 30° in 10° increments on the cutting force
and cutting energy were determined at fixed knife edge and
shear angles of 20° and 90°, respectively. Finally, the effects
of varying knife shear angles from 60° to 90° in 10° increments
on the cutting force and cutting energy were determined
at fixed knife edge and oblique angles of 20°.
