In order to obtain the optimal range of surface roughness processing parameters for cold roll-beating spline in a given range, for the involute spline, the surface roughness test of cold roll-beating spline was carried out, and the exponential function empirical model of surface roughness for cold roll-beating spline was constructed. Then, the sensitivity of surface roughness for cold roll-beating spline to processing parameters was analyzed, and the stable and unsteady domains of cold roll-beating spline processing parameters were determined. Furthermore, the results of surface roughness test for cold roll-beating spline were analyzed, and the stable and unstable domains determined were optimized. The results show that the surface roughness is most sensitive to the changes of rotational speed of rolling wheel and is less sensitive to the changes of feeding rate of workpiece, and the preferred ranges of the rotational speed of rolling wheel and the feeding rate of workpiece are 2032-2258 r·min-1 and 21-35 mm·min-1 respectively. The research results provide theoretical basis and experimental basis for the control of surface roughness for cold roll-beating spline.
