Abstract
A method in which a cutting tip is ground to form an intermediate cutting tool; a first predetermined portion of the intermediate cutting tool is masked; a wear-resistant material is deposited onto the exposed portion of the intermediate cutting tool to form a sharpened cutting tool; and a workpiece is cut with the sharpened cutting tool.
Claims22
A method comprising:
- grinding a cutting tip to form an intermediate cutting tool, the cutting tip of the intermediate cutting tool comprising a planar face and a sharpened cutting edge at a distal end of the planar face, the cutting tip being relieved on a side and an end that cooperate with the planar face to define the sharpened cutting edge;
- masking the intermediate cutting tool such that a first predetermined portion of the planar face is exposed and a second predetermined portion of the planar face is not exposed, the exposed portion of the planar face including the sharpened cutting edge and including at least portions of the end and the side that cooperate to define the cutting edge;
- depositing a wear-resistant material onto the exposed portion of the planar face of the intermediate cutting tool to form a sharpened cutting tool;
- and
- forming a workpiece, the workpiece being cut with the sharpened cutting tool.

- masking the intermediate cutting tool such that a first predetermined portion of the planar face is exposed and a second predetermined portion of the planar face is not exposed, the second predetermined portion being spaced apart from the sharpened cutting edge;
- depositing a wear-resistant material onto the first predetermined portion of the cutting tip of the intermediate cutting tool to form a sharpened cutting tool, the wear-resistant material not being deposited on the second predetermined portion of the cutting tip of the intermediate cutting tool;
- and
- cutting a workpiece with the sharpened cutting tool.
