Device and method for machining a surface of a workpiece

A method for machining a surface of a workpiece, comprising:

• rotating the workpiece about a workpiece rotational axis,
• moving a tool having a tool rotational axis and at least one blade having a blade curvature such that an active point of the blade comes into engagement with the workpiece, and
• pivoting the tool with a pivot motion about the tool rotational axis and moving the tool with an advancing motion such that the active point of the blade shifts along the blade,
• wherein the advancing motion is defined by a curve having at least a first radius of curvature and a second radius of curvature.

A method for machining a surface of a workpiece, comprising:

• rotating the workpiece about a workpiece rotational axis,
• moving a tool having a tool rotational axis and a blade having a blade length and a blade radius of curvature such that an active portion of the blade comes into engagement with the workpiece, and
• moving the tool such that the active point of the blade shifts along the length the blade,
• wherein the moving occurs along a first curve having a first radius of curvature and along a second curve having a second radius of curvature, and
• wherein the active point of the blade has a length less than the blade length.
