Abstract
A method for dressing a tool of a gear grinding machine, including a workpiece holder and a tool holder, is provided. The tool holder, arranged on a machining head, is rotatable about a first axis of rotation, and is linearly movable via a first linear axis of movement, wherein a workpiece clamped in the workpiece holder can be machined by a tool clamped in the tool holder. The machine furthermore includes a dressing unit with a dressing tool holder rotatable about a second axis of rotation, wherein a dressing tool accommodated in the dressing tool holder is used for dressing the tool clamped in the tool holder. During the dressing operation the machining head is pivoted about the swivel axis in dependence on a tool profile and is linearly moved with the first linear axis of movement.
