Simulative surface topography prediction of tribological surfaces on whirled thread flanks

verfasst von: Berend Denkena, Benjamin Bergmann, Christian Wege, Hans Gereke-Bornemann, Moritz von Soden
Abstract: This paper investigates the surface texture on trapezoidal thread flanks manufactured by whirling, which is used for machining long threaded spindles. An analytical and numerical approach for describing surface texture is compared, and texture parameters are developed based on existing methods. Although the analytical model provides a good description of texture height and length, it has limitations in representing the surface as a topography. In contrast, the numerical approach enables detailed modeling of the surface topography on the thread flank as a function of the process parameters. The effective number of flank cutters is found to significantly influence the resulting topography, leading to differences between the measured values and the analytical model within a specified investigation range. Using a material removal simulation, this effect could be explained by the flank cutter position error. In addition, material removal simulation offers great potential for optimizing the surface texture on thread flanks and for tailoring tribologically optimized surfaces in the whirling process.
