Statistical Analysis of Reliability Field Data in CNC System
Based on reliability field data of failure in the CNC system (Computer numerical control), failure spots, failure patterns and failure mechanism of the key parts in the CNC system was analyzed. According to the field data of reliability, the key subsystems of frequent failure were discovered through statistical analysis and criticality analysis. The fault tree was established, then the weak part of reliability was point out, and the basis for its reliability improvement was provided.
