Method for creating or machining toothings on workpieces by gear shaping with regulation of spindle rotation setpoints

A method for creating or machining toothings on workpieces in rolling machining engagement by gear shaping, in which an NC control of the rotary spindle drives of workpiece and tool comprises regulation of the rotation angle position of each particular spindle to setpoints depending upon the process parameters associated with the process design underlying the method, characterized in that data containing information relating to a deflection caused by the process forces that arise during machining and resulting in profile shape deviations on the workpiece, of the position of the tool flanks of tool and workpiece out of their position intended as per the process design, are used to determine a correction, taking the deflection into account, of the rotation angle position of the workpiece spindle and/or tool spindle and thus to modify the setpoints of the regulation wherein an amplitude of the setpoint correction is determined depending upon one or a plurality of the parameters:

• tool and workpiece diameter and number of teeth, resilience of the tool and workpiece, toothing module, helix angle of the toothing.
