摘要：Deformation of the big-diameter length rate shaft and turning process control mechanism were studied. When it was supported by the central frame, its theoretical mechanics models were established. Based on probability theory, considering the randomness of cutting force, elastic modulus, its length and its diameter, its theoretical model was established to calculate its standard deviation of the roundness. Moreover, its dynamic response finite element model was established, and the model was verified through comparison with the theoretical calculation results. The study provides the method and theoretical basis for the precision turning process planning of the big-diameter length rate shaft.
