dc.description.abstractThe cutting characteristics values of plants are very important data for suitable design of a cutting and pruning machines and related equipment. The objective of this study was to determine of the cutting properties of cotton stalk with use of the multiple regression model for serrated (knife-edge thick and knife-edge thin) and flat-edge knives type. In accordance of this purpose, cutting tests were made with three different type knives. In this study, the knife edge angle, knife type and stalk diameter were selected independent variables. Dependent of these parameters, the cutting force, cutting strength and cutting energy were measured for each type of knife. This study clearly that predict cutting force, cutting strength and cutting energy are influenced by knife type, knife angle and cotton stalk diameter (P<0.01). According to regression equations, the cutting force and cutting energy increased with increase stalk diameter for all type of knife because the partial regression coefficient of cotton stalk diameter is positive. However, the cutting force and cutting energy decreased with increase knife edge angles because the partial regression coefficient of cutting angle is negative. The best results were obtained serrated types knives. The highest values were obtained at flat-edge knives. With using of proper knife type and angle, cutting force and cutting strength and cutting energy values can be reduced. As a result, we can say that the flat-edge knife type is not suitable, when compared to serrated knife types. As a result we can recommend that the serrated type knife for a new design of cutting machine and pruning for cotton shoots topping. According these results, if one is interested to study the joint affect of all these variables on cutting properties, one can use this technique.en_US
