The reliability of technological processes of processing of details by the dynamic method of surface plastic deformation
The article examines the processes of machining dynamic methods of surface plastic deformation (SPD) in terms of improving their reliability. The factors that have a dominant influence on the performance and quality of processing. The paper presents the improved probability-theoretic model of the formation of the quality of the surface layer in the processing by dynamic methods of SPD. Based on the results of theoretical studies suggested depending influence of the main technological parameters of centrifugal rotary processing (CRP) and vibratory finishing and hardening treatment for surface finish, hardened layer depth and degree of hardening. Calculations of the effect of tolerances main quality parameters of the surface layer and technological regimes centrifugal rotary processing on the value of the offset coefficient, instantaneous dispersion and stock accuracy which characterize the reliability of technological processes. The calculations graphed. The resulting model can be used for analytical prediction reliability parameters of technological processes. Using the method presented, the choice of technology can be processing modes to choose a combination thereof, which will ensure the required quality of machined parts
