Beschreibung

In this paper, a novel approach for cutting simulation of skive hobbing is presented. Skive hobbing is a process applied for finishing of already hardened gears. The process is characterized by varying tool engagements and very small chip thicknesses. The paper describes the process-modeling and the analysis of the workpiece-tool contact. For efficient modeling, a novel dexel-based method is presented for the descriptionof a gear Segment with discretized stock allowance. Characteristic of the method is an analytical description of the target workpiece contour which allows to describe Points of the surfaceby Cartesian coordinates on the winding off. Dexel are oriented orthogonal to the Surface of the final workpiece contour. The initial lengths of the dexel describe the stock allowance. By cutting these dexel with a tool, a time- and positon-dependent prediction of material removal values, e. g. with of undeformed chip or undeformed chip thickness., is possible. Selected results are presented and interpreted.
