Abstract

After the reliability analysis and maintainability analysis of numerical control machine tools, the influence degree of key components is analyzed respectively under the premise that it is not repairable and repairable. Under the premise that it is not repairable, the probability influence degree analysis is carried out, and on this basis, the critical influence degree analysis is carried out. Under the condition of repairable, Natvig method is used to analyze the comprehensive influence degree. Finally, the analysis results of influence degree were compared and analyzed. The Sorting results of influence degree of key components are consistent with the reality, and obtained results can further guide the reliability design and reliability growth of CNC machine tools. The Natvig method applied in this paper provides an effective way to study the repairable influence degree of CNC machine tools.
