Abstract:
A method for producing workpieces having inner and outer contours deviating from a circular shape, said method comprising the steps of:clamping at least one workpiece on a machine and driving said workpiece in rotation about a first rotational axis of said workpiece at a first constant velocity; arranging at least one tool on a carriage so as to be moveable radially to said first rotational axis of said workpiece as well as axially in the longitudinal direction of said first rotational axis of said workpiece; rotatably driving said tool about a second rotational axis of said tool that deviates from said first rotational axis of said workpiece such that an active cutting surface of said tool moves on a circular path at a second constant velocity; selecting said second constant velocity such that the revolutions per minute deviate from the revolutions per minute of said first constant velocity, wherein the deviation of said second constant velocity of said tool from said first constant velocity of said workpiece is a deviation of at least one of the sizes of said first and second constant velocities relative to one another and the directions of said first and second constant velocities relative to one another.
