Biomass cutting tests to determine the lowest value of the process force

Abstract

Abstract The paper presents experimental investigations of straw cutting in the form of triticale. The cutting was performed using a specialized testing station adapted for mounting on a MTS Insight 50 kN testing machine. It is allows to change the cutting blade, which made it possible to study the effect of changing the rake angle of its blade and the inclination of the cutting edge on cutting force value. The influence of the linear speed of the knife and the size of the gap between the blade and the counter-blade was also investigated. The results obtained allowed to select the most favorable values of the above-mentioned parameters of the cutting process in terms of obtaining the lowest value of the cutting force, which consequently determines the process energy consumption. Obtained results are not only guidelines for machine design and cutting devices, but these can also be used as input data for multicriteria analysis, which can result in looking for other values of process parameters not taken into account in the presented studies, and key ones in the direction of the next ones.
