Method of loading and unloading a workpiece with internal gearing, and loading and unloading device

Method for loading and unloading an internally toothed workpiece (2) having an axis of rotation into or out of a clamping position, said workpiece having an annular space enclosed by said workpiece,

• wherein the workpiece (2), which is held by a retaining device comprising at least two retaining regions, is brought from a receiving position into the clamping position by means of a conveying movement (α) so that said workpiece, when clamped, has internal toothing cut by a gear cutting tool (T) that occupies a cutting chamber (U) and, after the cutting, said workpiece, which is held by the retaining device, is returned from the clamping position to a delivery position in a return movement (ω),
• characterised in that, prior to the cutting, at least one of the retaining regions of the retaining device (10) carries out an evasive movement (δ) that is different from the return movement (ω) or that is different from a reverse conveying movement (−α), said evasive movement providing a free space within said annular space enclosed by said workpiece, said cutting chamber being located in said free space.
