In article reviewed advanced theoretical probability models of process quality formation quality of the surface layer in a centrifugal rotary process (CSO) details. Process CSO reviewed from the point of view reliability. Based on the results of theoretical studies were proposed the dependence of the influence of the main technological parameters centrifugal rotary finishing and strengthening treatment on the roughness of the processed surface, the depth of the hardened layer and the degree of hardening. Analysis of the technology processes CSO let to identify the factors exerting a dominant influence on the productivity and quality of processing. Conducted calculations of the influence the tolerances of the main quality parameters of the surface layer and technology modes centrifugal rotary processing of centrifugal rotary treatment on the magnitude of the coefficients offset instantaneous dispersion and stock accuracy which characterize the reliability of technological processes centrifugal rotary process. By results of calculations were constructed charts. Taking the presented methodology you can choose such a combination in choosing technological processes centrifugal rotary processing what will ensure the required quality of the workpiece.
Keywords: Reliability technology process, centrifugal rotary process, coefficients offset instantaneous dispersion, the roughness surface, the degree of hardening.
