Abstract
The aim of this research is to investigate experimentally and theoretically the parameters affecting on the deformation of internally-spline sleeves manufactured by ball spinning tool. Internally-spline sleeves have an increased attention since these parts serve as power transmission means in many industrial applications. The process was investigated experimentally and theoretically for commercial Aluminum tubes. The experimentally investigated variables were: the rotational speed of the mandrel 76, 150, 230 and 305 rpm; the axial feed, 0.3, 0.6, 0.9 and 1.21 mm/ rev; the cross in-feed 1.5, 2, 2.5 and 3 mm. An analytical expression was derived to predict the deformation loads. The theoretically investigated variables were: the mentioned axial feed and cross in-feed at 230 mandrel rotational speed. The effects of these variables on the forming load and the quality of formed sleeves were investigated. The results showed that, these variables affect the forming load and product quality. The optimum values of these variables were determined. The theoretical results with pile up have been found to be in close agreement with the experimental results.
