Rh Milling a Groove in a Machine Part

In the illustration above, the work is of cast iron, in which a groove $1⁄4$ inch wide is to be milled parallel with the hole. The piece is held on an arbor mounted in a V block and clamped to the surface of the table. Its overhanging end rests on a set screw tapped into the base of a knee bolted to the table, and a bolt and strap clamp the end firmly to the side of the knee.

A plain milling cutter, $1⁄4$ inch face, 2 inches diameter, is used, and the table is fed longitudinally.
