Analysis of Uncertainty Sources for Quality Management in the Bearing Ring Manufacturing Process

The article discusses the specifics of developing finishing technological operations in the manufacturing process of precision parts, using bearing rings as a case study. The main factors influencing deviations in the bearing ring production process are analyzed, with a focus on grinding operations. A study of subjectivity in technological decision-making is conducted. An expert assessment of the significance of various factors is employed. The absence of a single, unambiguous tool for objective technological decision-making is demonstrated. Factors and sources of uncertainty that lead to differences in technological decision-making are identified. A generalized decision-making model for the development of technological operations in the precision parts manufacturing process, accounting for uncertainties, is proposed.
