Abstract
A gear manufacturing apparatus for machining a gear workpiece wherein, when at least one of end regions in a tooth trace direction of each tooth of the workpiece is machined, a control device executes a specific machining control for adjusting a relative position of a tool to the workpiece based on information about the relative position computed by setting, as a machining reference position, a position of the tool on an outer edge line in an X-axis-orthogonal cross section different from a normal machining point such that a distance between a center of the tool and a center of the gear workpiece in the X-axis-orthogonal cross section when the at least one of the end regions is machined is larger than when the at least one of the end regions is machined by setting the normal machining point as the machining reference position.
