Analysis of Cutting Forces in Cross-Sawing of Wood: A Study of Sintered Carbide and High-Speed Steel Blades

This research deals with the processing of wood using a circular saw, which is associated several risks and factors that affect wood-splitting process. One them wear teeth saw blade change magnitude cutting forces. The aim this study to compare real measured values theoretical when Norway spruce two types blades, i.e., sintered carbide (SC) high-speed steel (HSS), diameter 600 mm 54 56 teeth, respectively. Experimental measurements were carried out on special test device possibility moving tested into devices simple replacement system. results contributions show significant differences, based defined represent feed speed, are supported by FEM analysis forces in process wood—when changing design blade. experiment conditions (cutting speed speed) do not have effect size stress for HSS discs ranged from 14 22 MPa. Significantly larger differences recorded SC, where maximum stresses around MPa ones 25 When disc SC slices, range 76 94 N 40 44 N.
