Software and Hardware

Power Skiving is a productive gear machining process with a specific cutting edge that combines the productivity of gear hobbing with the geometric flexibility of gear shaping. It is particularly suitable for internal toothing and for external toothed workpieces with interfering contours. At present, there is still little empirical knowledge available on the design of Power Skiving processes, as the process has only recently become available on the market. The design process can be supported by the use of a mathematical process model and user software. The process model for the SkiveAll software was developed at Fraunhofer IWU. It contains algorithms for the design of Power Skiving processes - from workpiece definition and kinematic design to the calculation of tool geometry and process analysis functions. The software has a modular structure; the central component is the design module.

The deviation of the tool path during machining has so far been a major challenge for the user: it significantly influences the quality of the final workpiece, but is usually unknown. In order to avoid deviations, complex tests on the workpiece are therefore necessary, which can only be reacted to with a time delay. Scientists at Fraunhofer IWU have now developed a monitoring system that generates precise information about the real tool path in practically real time and thus enables corrections to be made during machining or even in the path planning process. The uneconomical testing effort can thus be reduced by a factor of 10 in individual applications. Translated with DeepL
