On Hobbing of Watch Gears

Journal of the Japan Society of Precision Engineering, 1970
For many watch-gear-tooth profiles approximate cycloid curves consisting of arcs of circles and straight lines are being used. But watch-gears cannot always be hobbed, for in some cases there is no mating rack profile which is the tooth shape of the hob.
