The Woodruff key slot milling cutter (Figure 4-36) must have the same diameter as that of the key
The upper portion fits into a slot in a mating part, such as a pulley or gear. The circular side of the key is seated into a keyway which is milled in the shaft.
The Woodruff keys are semicylindrical in shape and are manufactured in various diameters and widths. The most commonly used types of keys are the Woodruff key, the square-ends machine key, and the round-end machine key (Figure 4-35). The type of key and corresponding keyway to be used depends upon the class of work for which it is intended. A keyway is also machined in the mounted member to receive the key. Keyways are grooves of different shapes cut along the axis of the cylindrical surface of shafts, into which keys are fitted to provide a positive method of locating and driving members on the shafts.
