Abstract: In the rapid development of high-end equipment, the complex curved surface part is growing in demand. To improve the machining efficiency of the complex curved surface turning, this study proposes a cutting speed scheduling method with kinematic constraints. Based on the calculation of feature points of the desired curve, the desired curve is sectioned into segments. The feasible kinematic parameters of the drive axis in each segment are derived, then the cutting speed is scheduled with the S-curve motion profile. The contrast experiments show that the surface roughness of the part machined with the proposed cutting speed scheduling method satisfied the requirement, meanwhile, compared with the constant spindle speed cutting and the constant cutting speed turning, the machining time of the proposed method is respectively reduced by 32.54% and 21.46%. The contribution of this study is significant for the development of complex curved surface part turning.
