EN This work presents an experimental study of cutting corn stalks for thermal energy generation. The study was carried out for the values of blade angle in the range of a = 30–80°, distance between the blade and the counter-blade g = 0.1, 0.2, 0.3 mm and the velocity of the blade V = 1, 4, 8 mm/s. The measured results were used to determine shear stresses and cutting energy. The ANOVA variance analysis tool was used to determine the interactions between the initial process variables and the responses. Furthermore, the blade load-state analysis was carried out, together with determining the knife blade strength characteristic, based on the determination criteria for the strength of the cutting tool. Therefore, the force ratio F_cc/T_x was determined as the determinant of strength, and its variance characteristic in the function of the blade angle, a, was used in the performed optimization. The optimization criteria entailed the determination of such values of the blade angle, a, for which the cutting force value, F_cc, and the coefficient of knife blade strength approached the minimum value. Hence, the optimized value of the blade angle, a, within the range 40–60° was determined, depending on the assumed weight parameters for the above-mentioned criteria.
