Abstract
A method for shaping the edge of a blade element including first means for removing material from the blade having a first position to engage a portion of the edge of the blade, second means for supporting the blade during translation thereof relative to the first means while successive portions of the blade are in engagement with the first meams, third means for guiding the blade during translation and for presenting the edge portions for engagement with the first means at a predetermined angle and fourth means for holding the first means, the second means and the third means against translational movement with respect to each other.
Claims6
A method of shaping an edge of a blade having a leading edge and a trailng edge to a predetermined profile including:
- presenting successive portions of one of said edges for engagement with an abrasive element by translating said blade relative to said abrasive element;
- supporting and locating said blade such that said successive portions are presented to said abrasive element at a predetermined location;
- guiding said blade by engaging said blade with a cam surface configured to represent the loci of a portion of said blade such that said successive portions of said one of said edges are presented to said abrasive element at a predetermined angle at said predetermined location;
- and
- represent at least one of said loci which does not occupy the same point in space as other of said loci as successive portions of said blade are presented for engagement with said abrasive element at said predetermined angle.
