PEREZ-REYES, Rigoberto Antonio et al. Numerical Model for Sugarcane Base Cutting. Rev Cie Téc Agr [online]. 2022, vol.31, n.2  Epub 14-Mayo-2022. ISSN 2071-0054.

In the present work, a numerical model is developed for sugarcane base cutting from experimental data obtained in five varieties of cane evaluated in the Physics and Resistance of Materials Laboratories of Ciego de Ávila University. The performance of the BONEM and BUSSOLA base-cutter blade was analyzed in relation to process parameters such as stresses, cutting force and cutting moment. It was shown that BUSSOLA cutter blade had a better performance than BONEM for each of the varieties tested. In the analysis of a model with average magnitudes of the physical-mechanical properties of the stems of the varieties examined, the behavior graphs of the cutting forces over time and the Force - Displacement graphs for both segments were obtained. The main results show that there are no representative differences in relation to the magnitude of the stresses generated in the stems of each of the sugarcane varieties when they are cut with the different cutter blades. In addition, it was shown that the magnitudes of cutting force and cutting moment generated with the use of BONEM cutter-blade are significantly higher than those generated with BUSSOLA cutter-blade.
