Abstract: A tip dresser cutter including a circumferential portion having a circular shape rotatable about an axis of rotation, a center portion located radially inward from the circumferential portion proximate the axis of rotation, and a cutting flute extending radially between the center portion and the circumferential portion. The cutting flute including a leading edge, a trailing edge, a radially inward canted surface extending between the leading edge and the trailing edge. The radially inward canted surface includes a first section extending between the center portion and a first location on the cutting flute and a second section extending between the first location on the cutting flute and a second location on the cutting flute. The second section of the radially inward canted surface including a curved portion that is parallel to a plane of rotation of the cutting flute.

Abstract: A system for electrode dressing including a cutter with a rim and a center land supported on the rim by a number of flutes defining openings between the flutes. The flutes and the center land define a cutting profile of the cutter. The cutter is configured to rotate about an axis passing through the center land. Cutting edges are disposed on the flutes and are made of a first material having a Vickers hardness (HV) of at least 850 HV, overlaid by a second material having a Vickers hardness of at least 3200 HV. The cutter profile comprises a face cutting profile extending radially outward from the axis that is disposed at an angle of less than six-degrees relative to a radial normal of the cutter.
