Abstract

The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface thereon. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter is used to cut a surface of the part during a milling operation where the diamond cutter contacts the part a number of times with each rotation of the spindle of a milling machine. The diamond cutter has a cutting edge and a land. The cutting edge cuts the surface of the part and the land burnishes the surface of the part to form a highly reflective and smooth surface. Thus, the diamond cutter cuts and burnishes portions of the part, thereby eliminating a subsequent polishing step.

Dependent claims

A cutting tool assembly comprising:

a holder configured to rotate about an axis;
and
a cutting tool radially attached to the holder such that the cutting tool rotates about the axis during a cutting operation, the cutting tool comprising:
a shank having a first end secured to the holder, and
a cutter attached to a second end of the shank opposite the first end, the cutter comprising a cutting edge, a heel and a land corresponding to a substantially flat surface between the cutting edge and the heel, wherein during the cutting operation the cutting edge and the land are substantially parallel to the axis, wherein the cutting edge cuts material from a workpiece to form a surface of the workpiece having peaks and troughs, and the land removes at least a portion of the peaks, thereby burnishing the surface of the workpiece, wherein a relative angle of the land with respect to the cutting edge is adjustable so as to control an amount of burnishing by the land.
