A machining apparatus machines a surface of a workpiece by feeding, relative to the workpiece, a cutting tool having a plurality of cutting edges A to D with tips of the cutting edges A to D arranged at equal intervals. The machining apparatus performs a cutting process of cutting the surface of the workpiece with the plurality of cutting edges A to D and a feeding process of feeding the cutting tool relative to the workpiece by a predetermined feed amount to form a plurality of grooves on the surface of the workpiece. The predetermined feed amount is set to a length that is not an integral multiple of the interval between the tips of cutting edges.

The invention relates to a method for machining a toothing (2) having an axis of rotation (C), in which a machining tool (4), which is rotationally driven about its axis of rotation (B), removes material from the toothing while executing a relative motion between the machining tool and toothing to generate a flank geometry of the toothing, which has been predefined over the full width of the toothing, in a machining operation, wherein the predefined flank geometry matches a motion control that defines a motion path of the tool center with respect to the toothing axis of rotation, said motion control having a defined, non-vanishing axial advancement with a defined advancing motion between machining tool and toothing, wherein in a first machining process, the relative motion is only executed for generating a part, more particularly a significant part (5), of the flank geometry according to this motion control, while a further part, more particularly the remaining part (6), of the flank geometry is generated in a second machining process, in which the distance between the tool center and the toothing axis of rotation with respect to the fixed motion path changes in a manner wherein the tool center moves away from the toothing, and in which the change to the machining operation caused thereby is counteracted by an additionally executed change in motion of the relative motion with respect to the motion control of the first machining process.
