A professional who sets up and operates one or more straight-tooth bevel-gear generating machines to cut and shape straight teeth on metal bevel-gear blanks, according to machining instructions and knowledge of gear generating procedures. Respnsibilities include:

• Reads blueprint or machining instructions to determine machine settings, fixtures and cutters to use, and gear type, dimensions, tolerances, and number of teeth to be generated.
• Mounts workpiece on arbor and positions it to cutting angle.
• Positions and clamps two cutters in toolheads, and positions cutter cradle to specified angle, using wrenches.
• Mounts gears and cams in machine to control rotation speed and indexing of workpiece, cutting speed, and rolling motion of cutter cradle.
• Starts machine, turns valve handle, and directs flow of coolant against reciprocating cutters and workpiece.
• Verifies conformance of machined gear to specifications, using micrometers, master gears, and special gear inspection equipment.
• May compute such data as gear dimensions and machine settings, applying knowledge of shop mathematics.
• May machine plastics or other nonmetallic materials.
• May be required to have experience with custom or production work, or with particular material, product, or size, type, or trade name of machine.
