Abstract
A cutting tool comprises a first cutting edge and a second cutting edge where the cutting edges are movable into engagement with one another. At least one of the cutting edges comprises an edge tip extending along at least a portion of the cutting edge. The edge tip has a curved outer surface that in cross-section is bounded by a first line defined by the equation y=74x2 where x is within the range −0.023 inches≦x≦0.023 inches and a second line defined by the equation y=294x2 where x is within the range −0.012 inches≦x≦0.012 inches. The outer surface may also be within a range defined by predetermined coordinates.
Claims19
A cutting tool comprising:
- a first cutting edge and a second cutting edge, said cutting edges being movable into engagement with one another;
- said first cutting edge comprising a edge tip extending along at least a portion of said cutting edge, said edge tip having a curved surface that is within the range defined by a first line defined by the equation y=74x2 where x is within the range −0.023 inches≦x≦0.023 inches and a second line defined by the equation y=294x2 where x is within the range −0.012 inches≦x≦0.012 inches.
A cutting tool comprising:
- a first cutting edge and a second cutting edge, said cutting edges being movable into engagement with one another;
- said first cutting edge comprising a edge tip extending along at least a portion of said cutting edge, said edge tip having an outer surface that is within the range defined by a first line defined by the equation y=74x2 where x is within the range −0.023 inches≦x≦0.023 inches and a second line defined by the equation y=294x2 where x is within the range −0.012 inches≦x≦0.012 inches, where seven values of y and seven values of x are used to define the curve.
A cutting tool comprising:
- a first cutting edge and a second cutting edge, said cutting edges being movable into engagement with one another;
- said first cutting edge comprising a edge tip having a distal end and extending along at least a portion of said cutting edge, said edge tip having an outer surface that is within the range defined by a first line defined by the equation y=74x2 where x is within the range −0.023 inches≦x≦0.023 inches and a second line defined by the equation y=294x2 where x is within the range −0.012 inches≦x≦0.012 inches, and where y extends between 0 and 0.040 inches from the distal end.
A method of making a cutting tool comprising;
- providing a first cutting edge and a second cutting edge where the first cutting edge and the second cutting edge are movable into engagement with one another;
- providing a edge tip along at a least a portion of the first cutting edge;
- shaping the edge tip to have a curved surface that is within the range defined by a first line defined by the equation y=74x2 where x is within the range −0.023 inches≦x≦0.023 inches and a second line defined by the equation y=294x2 where x is within the range −0.012 inches≦x≦0.012 inches.
