TLDR
In this article, a method for creating or machining toothings on workpieces in rolling machining engagement, in particular 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 on the process parameters associated with the process design underlying the method, wherein 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 andAbstract:
The invention relates to a method for creating or machining toothings on workpieces in rolling machining engagement, in particular 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 on the process parameters associated with the process design underlying the method, wherein 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 workpiece spindle and/or tool spindle and thus to modify the setpoints of the regulation.read more
