Abstract
Residual stress is an important parameter in the evaluation of the performance of a cold rolling spline surface. However, research on cold rolling spline is rare. To improve the surface property of a spline, an involute spline is selected as the object of this study. The contour method for determining cold roll-beating residual stress involves measuring the force spatial distribution, performing a statistical analysis of the experimental results, establishing the parameters for the tooth profile for different positions (dedendum, pitch, and addendum) of residual stress, and determining the effect of pressure on the relationship between stress and the depth of the cold roll-beating. A response surface method is used to establish the spline tooth profile of the dedendum, pitch, and addendum of the residual stress and different depths of the stress layer to obtain the parameters of a multiple regression model and perform a comparative analysis of the experimental and prediction results. Research indicates that the prediction results have high reliability. The establishment of this model has important guiding significance to control the residual stress in the cold roll-beating forming process, optimize the cold roll-beating processing parameters, and improve the surface properties of cold rolling spline.

Cold roll-beating technology is a new type of chipless nearnet forming technology that enables environmental protection and energy savings with high efficiency, a high material utilization rate, and an extensive application value in the automobile industry and the aerospace sector and for major strategic equipment manufacturing processes
How do different cold roll-beating process parameters affect the workpiece residual stress state and its distribution? What method can be employed to predict the surface residual stress of a cold roll-beating workpiece when setting the cold rolling process parameters? What method can be employed to optimize the cold roll-beating process parameters according to the stress state of the workpiece application? Research on the spatial distribution and prediction model of the residual stresses in cold roll-beating during nonuniform thermal mechanical coupling is necessary
The residual stress distribution at the surface of the spline tooth profile was measured for cold roll-beating, the measurement data were analyzed, and the influence of different cold roll-beating parameters on the spatial distribution of the residual stress in different parts of the spline tooth profile was clarified
