A band saw profiling machine includes an indexing mechanism having a feed finger mechanically linked to a caliper finger for reciprocating movement therewith. The caliper finger is urged toward the feed finger during an indexing movement of the indexing mechanism to measure the spacing between adjacent teeth of a band saw blade on-the-fly and concurrently with advancement and sharpening of the saw blade. The tooth spacing measurement is then used in the band saw sharpening machine to provide feedback for a subsequent indexing movement of the indexing mechanism, to accurately position the band saw blade for sharpening of a row of teeth. A control unit of the sharpening machine accepts input of shape factors from an operator that define the pattern of motion of the indexing mechanism, the grinding wheel, or both, for sharpening of irregular tooth shapes.
