Abstract:
A band saw blade for cutting a workpiece and generating a chip load on each tooth upon cutting the workpiece, comprising:a plurality of teeth defining a pitch pattern of at least eight teeth, and set patterns within each pitch pattern; wherein each set pattern is defined by an unset leading tooth and a plurality of offset trailing teeth, each offset trailing tooth is offset in a respective set direction relative to the unset leading tooth, and each offset trailing tooth defines approximately the same set magnitude as every other like set tooth within the respective set pattern;each tooth within each set pattern defines a pitch between the respective tooth and the preceding tooth in a cutting direction of the saw blade, and an accumulated pitch between the respective tooth and a preceding tooth of like set direction in the cutting direction of the saw blade; andthe ratio of pitch to accumulated pitch for each tooth of like set direction within each set pattern increases from one tooth to the next in the direction opposite the cutting direction of the saw blade for distributing the chip load over the teeth of the saw blade.
