Abstract
A method of machining a tooth flank of a gear with a gear machining tool. The method comprises rotating the tool and bringing the tool and the tooth flank into contact. Relative movements are provided between the tool and the gear to traverse the tool across the tooth flank along a path whereby the path produces a tooth flank geometry of a form which, when brought into mesh with a mating tooth flank under no load or light load to form a tooth pair, provides a motion graph curve comprising a sinusoidal portion (62, 89, 91, 90, 63) and a parabolic portion (92).
