Surface Quality of Softwood Sawing by Various Tooth Type of Saw Blades
Commercial wood manual usually provides the basic physical properties of wood.However, very limited information about the machining performance of softwood is available for the furniture makers. In this experiment,seven tungsten carbide tipped saw blades with six teeth types (ST,KC,ATB,ATB+R,GJ, and KF) will be mounted on an auto-feeder table saw.The feed speeds will be changed during sawing.Teeth type of GJ and KF will be used to rip and ST, KC, ATB and ATB+R to crosscut Canada SPF and hemlock, respectively.The results of this study showed that the level of torn grain was depended on the type of crosscut sawing blade.According to this study, KC saw blade could obtain the best surface quality in crosscut sawing SPF and hemlock. KC saw blade also could produce clear edge in crosscut sawing of hemlock.On the contrary, ATB+R produced more serious burry edge in spruce and fir. Meanwhile, KC crosscut sawing blade consumed less power than other types of saw blade for SPF and hemlock. Furthermore, although GJ could produce finer surface for ripping softwood, KF40 may be the best choice because of less power consumption.
