Abstract: The goal of this project was to evaluate the wear resistance of different carbide associated with different cutting parameters and teeth geometry, during the sawing of wet spruce. We tried to simulated working conditions of a modern sawmill, with high feed and cutting speeds. Test saw blades, were tipped with tree grades of carbide, three rake angles and three different numbers of teeth. We used a Taguchi table to find the best compromise with all these parameters to reduce edge recession, during spruce rip-sawing, and we looked at energy consumption while machining MDF at different points. The aim of this study is to find the best carbide to saw spruce, according to a modern sawmill cutting parameters. With the collaboration of SIAT-BRAUN (the most important French softwood sawmill), RBD ONCI JAGUAR (a tool manufacturer) and CERATIZIT (European leader of carbide production), the goal was to increase circular saw life and decrease energy consumption of circular saw blades used in sawmill.

Key words: carbide, wear, saw blade.
