Gear cutting WikipediaFigure 114 Gear Cutting Operation

Gear cutting is any machining process for creating a gearThe most common gear cutting processes include hobbing broaching milling and grindingSuch cutting operations may occur either after or instead of forming processes such as forging extruding investment casting or sand casting Gears are commonly made from metal plastic and woodAlthough gear cutting is a substantial industry Milling Figure 114 Gear Cutting Operation Helical Milling Operation Helical milling produces helical flutes or grooves on the periphery of a cylindrical or conical workpiece This is performed by swiveling the table to the required helix angle then rotating and feeding the workpiece against revolving cutting edges of milling cutter
