Cutting force test of sugarcane stalk

Cutting force test is an important means to study the mechanics of cutting sugarcane stalks. A single blade cutting test equipment was made in this paper. Three-factor and three-level orthogonal test was done to study their influences on unit cutting force and maximum cutting force. The three factors are sliding cutting angle, blade tilt angle, and cutting velocity. It is found that: 1) The significant order of influence on unit cutting force is cutting velocity, sliding cutting angle, and the blade tilt angle; The significant order of influence on maximum cutting force is cutting velocity, the blade tilt angle, and sliding cutting angle. Blade tilt angle has some significant influence on maximum cutting force, but has less influence on unit cutting force; 2) It would be more reasonable to use unit cutting force as test index when studying cutting force on big stem; 3) There is a linear relationship between unit cutting force and cutting velocity. When the cutting velocity is higher, the cutting force will be higher.
