1. A cutting tool assembly arranged to perform a cutting operation along an edge of a part, comprising:
- a tool holder configured to rotate about an axis;
a first cutting tool attached to the tool holder and comprising a first cutting edge, the first cutting edge having a straight cutting surface configured to cut a planar surface along the edge of the part, the planar surface meeting an adjacent surface at a junction region; and
a second cutting tool attached to the tool holder and comprising a second cutting edge having a curved cutting surface, the curved cutting surface configured to round the junction region between the planar surface and the adjacent surface.

Abstract
The embodiments described herein relate to methods, systems, and structures for cutting a part to form a highly reflective and smooth surface. In some embodiments, the part includes substantially horizontal and vertical surfaces with edges and corners. In described embodiments, a diamond cutter can be 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. In some embodiments, a complex feature having planar and curved surfaces is cut into a part.
