Power Skiving - the process

Power Skiving is a productive gear cutting process with a specific cutting edge that combines the productivity of gear hobbing and the geometric flexibility of gear shaping. It is particularly suitable for internal gears and for external gears with interfering contours. At present, little experience is available on the design of Power Skiving processes, as the process has only recently become available on the market. In addition, the multi-cut strategies, typical of the process, are characterized by a high number of degrees of freedom.

SkiveAll application software

The design process can be supported by using 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 module is the design module. Here, a technology proposal is developed on the basis of the workpiece and gear data and then checked for collision in a 3D environment. As a result, a cutting sequence including all cutting values, machine settings and further information is generated for each individual cut. Costs, times and tool usage for the individual technology variants can be compared in an overview.
