• ### GEARS AND GEAR CUTTINGMWDropBox

A gear is made by cutting a series of equally spaced specially shaped grooves on the periphery of a wheel (see fig. 14-1). To calculate the dimensions of a spur gear you must know the parts of the gear. You also must know the formulas for finding the dimensions of the parts. To cut the gear you must know what cutter to use and how 14-1
